NAME
	 cmake - Cross-Platform Makefile Generator.

USAGE
	 cmake [options] <path-to-source>
	 cmake [options] <path-to-existing-build>

DESCRIPTION
       The  "cmake" executable is the CMake command-line interface.  It may be
       used to configure projects in scripts.  Project configuration  settings
       may be specified on the command line with the -D option.	 The -i option
       will cause cmake to interactively prompt for such settings.

       CMake is a cross-platform build	system	generator.   Projects  specify
       their  build process with platform-independent CMake listfiles included
       in each directory of a source tree with the name CMakeLists.txt.	 Users
       build  a project by using CMake to generate a build system for a native
       tool on their platform.

OPTIONS
       -C <initial-cache>
	      Pre-load a script to populate the cache.

	      When cmake is first run in an empty build	 tree,	it  creates  a
	      CMakeCache.txt  file and populates it with customizable settings
	      for the project.	This option may be used to specify a file from
	      which  to	 load  cache entries before the first pass through the
	      project's cmake listfiles.  The  loaded  entries	take  priority
	      over  the	 project's default values.  The given file should be a
	      CMake script containing SET commands that use the CACHE  option,
	      not a cache-format file.

       -D <var>:<type>=<value>
	      Create a cmake cache entry.

	      When  cmake  is  first  run in an empty build tree, it creates a
	      CMakeCache.txt file and populates it with customizable  settings
	      for  the	project.  This option may be used to specify a setting
	      that takes priority  over	 the  project's	 default  value.   The
	      option may be repeated for as many cache entries as desired.

       -U <globbing_expr>
	      Remove matching entries from CMake cache.

	      This option may be used to remove one or more variables from the
	      CMakeCache.txt file, globbing expressions using * and ? are sup‐
	      ported.  The option may be repeated for as many cache entries as
	      desired.

	      Use with care, you can make your CMakeCache.txt non-working.

       -G <generator-name>
	      Specify a build system generator.

	      CMake may support multiple native build systems on certain plat‐
	      forms.   A  generator is responsible for generating a particular
	      build system.  Possible generator names  are  specified  in  the
	      Generators section.

       -T <toolset-name>
	      Specify toolset name if supported by generator.

	      Some  CMake generators support a toolset name to be given to the
	      native build system to choose a  compiler.   This	 is  supported
	      only on specific generators:

		Visual Studio >= 10
		Xcode >= 3.0

	      See native build system documentation for allowed toolset names.

       -Wno-dev
	      Suppress developer warnings.

	      Suppress	warnings  that	are meant for the author of the CMake‐
	      Lists.txt files.

       -Wdev  Enable developer warnings.

	      Enable warnings that are meant for  the  author  of  the	CMake‐
	      Lists.txt files.

       -E     CMake command mode.

	      For  true	 platform  independence, CMake provides a list of com‐
	      mands that can be used on all systems. Run with -E help for  the
	      usage information. Commands available are: chdir, compare_files,
	      copy,  copy_directory,  copy_if_different,  echo,	  echo_append,
	      environment,  make_directory,  md5sum, remove, remove_directory,
	      rename, tar, time,  touch,  touch_nocreate.  In  addition,  some
	      platform	specific  commands are available. On Windows: comspec,
	      delete_regv, write_regv. On UNIX: create_symlink.

       -i     Run in wizard mode.

	      Wizard mode runs cmake interactively without a GUI.  The user is
	      prompted	to  answer  questions about the project configuration.
	      The answers are used to set cmake cache values.

       -L[A][H]
	      List non-advanced cached variables.

	      List cache variables will run CMake and list all	the  variables
	      from  the	 CMake	cache  that  are  not  marked  as  INTERNAL or
	      ADVANCED. This will effectively display current CMake  settings,
	      which  can  then be changed with -D option. Changing some of the
	      variables may result in more variables being created.  If	 A  is
	      specified, then it will display also advanced variables. If H is
	      specified, it will also display help for each variable.

       --build <dir>
	      Build a CMake-generated project binary tree.

	      This abstracts a native build tool's command-line interface with
	      the following options:

		<dir>	       = Project binary directory to be built.
		--target <tgt> = Build <tgt> instead of default targets.
		--config <cfg> = For multi-configuration tools, choose <cfg>.
		--clean-first  = Build target 'clean' first, then build.
				 (To clean only, use --target 'clean'.)
		--use-stderr   = Don't merge stdout/stderr output and pass the
				 original stdout/stderr handles to the native
				 tool so it can use the capabilities of the
				 calling terminal (e.g. colored output).
		--	       = Pass remaining options to the native tool.

	      Run cmake --build with no options for quick help.

       -N     View mode only.

	      Only  load the cache. Do not actually run configure and generate
	      steps.

       -P <file>
	      Process script mode.

	      Process the given cmake file as a script written	in  the	 CMake
	      language.	  No  configure	 or generate step is performed and the
	      cache is not modified. If variables are defined using  -D,  this
	      must be done before the -P argument.

       --find-package
	      Run in pkg-config like mode.

	      Search  a	 package  using find_package() and print the resulting
	      flags to stdout. This can	 be  used  to  use  cmake  instead  of
	      pkg-config  to  find installed libraries in plain Makefile-based
	      projects	or  in	autoconf-based	 projects   (via   share/aclo‐
	      cal/cmake.m4).

       --graphviz=[file]
	      Generate	 graphviz   of	 dependencies,	 see  CMakeGraphVizOp‐
	      tions.cmake for more.

	      Generate a graphviz input file that will contain all the library
	      and  executable  dependencies in the project. See the documenta‐
	      tion for CMakeGraphVizOptions.cmake for more details.

       --system-information [file]
	      Dump information about this system.

	      Dump a wide range of information about the  current  system.  If
	      run  from	 the  top of a binary tree for a CMake project it will
	      dump additional information such as the cache, log files etc.

       --debug-trycompile
	      Do not delete the try_compile build tree.	 Only  useful  on  one
	      try_compile at a time.

	      Do  not delete the files and directories created for try_compile
	      calls. This is useful in debugging failed try_compiles.  It  may
	      however  change the results of the try-compiles as old junk from
	      a previous try-compile may cause a different test to either pass
	      or  fail incorrectly.  This option is best used for one try-com‐
	      pile at a time, and only when debugging.

       --debug-output
	      Put cmake in a debug mode.

	      Print extra stuff during the cmake run like  stack  traces  with
	      message(send_error ) calls.

       --trace
	      Put cmake in trace mode.

	      Print  a	trace  of  all	calls  made  and  from where with mes‐
	      sage(send_error ) calls.

       --warn-uninitialized
	      Warn about uninitialized values.

	      Print a warning when an uninitialized variable is used.

       --warn-unused-vars
	      Warn about unused variables.

	      Find variables that are declared or set, but not used.

       --no-warn-unused-cli
	      Don't warn about command line options.

	      Don't find variables that are declared on the command line,  but
	      not used.

       --check-system-vars
	      Find problems with variable usage in system files.

	      Normally,	 unused	 and  uninitialized variables are searched for
	      only in CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR. This  flag	 tells
	      CMake to warn about other files as well.

COMMANDS
       add_compile_options
	      Adds options to the compilation of source files.

		add_compile_options(<option> ...)

	      Adds  options  to	 the  compiler command line for sources in the
	      current directory and below.  This command can be	 used  to  add
	      any  options, but alternative commands exist to add preprocessor
	      definitions or include directories.  See	documentation  of  the
	      directory	 and  target  COMPILE_OPTIONS  properties for details.
	      Arguments to add_compile_options may use "generator expressions"
	      with  the	 syntax "$<...>".  Generator expressions are evaluated
	      during build system generation to produce	 information  specific
	      to each build configuration.  Valid expressions are:

		$<0:...>		  = empty string (ignores "...")
		$<1:...>		  = content of "..."
		$<CONFIG:cfg>		  = '1' if config is "cfg", else '0'
		$<CONFIGURATION>	  = configuration name
		$<BOOL:...>		  = '1' if the '...' is true, else '0'
		$<STREQUAL:a,b>		  = '1' if a is STREQUAL b, else '0'
		$<ANGLE-R>		  = A literal '>'. Used to compare strings which contain a '>' for example.
		$<COMMA>		  = A literal ','. Used to compare strings which contain a ',' for example.
		$<SEMICOLON>		  = A literal ';'. Used to prevent list expansion on an argument with ';'.
		$<JOIN:list,...>	  = joins the list with the content of "..."
		$<TARGET_NAME:...>	  = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.	The '...' must be a literal name of a target- it may not contain generator expressions.
		$<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
		$<BUILD_INTERFACE:...>	  = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
		$<C_COMPILER_ID>	  = The CMake-id of the C compiler used.
		$<C_COMPILER_ID:comp>	  = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
		$<CXX_COMPILER_ID>	  = The CMake-id of the CXX compiler used.
		$<CXX_COMPILER_ID:comp>	  = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.

		$<VERSION_LESS:v1,v2>	  = '1' if v1 is a version less than v2, else '0'.
		$<VERSION_EQUAL:v1,v2>	  = '1' if v1 is the same version as v2, else '0'.
		$<C_COMPILER_VERSION>	  = The version of the C compiler used.
		$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
		$<CXX_COMPILER_VERSION>	  = The version of the CXX compiler used.
		$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
		$<TARGET_FILE:tgt>	  = main file (.exe, .so.1.2, .a)
		$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
		$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

	      where  "tgt"  is	the name of a target.  Target file expressions
	      produce a full path, but _DIR and _NAME versions can produce the
	      directory and file name components:

		$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
		$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
		$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

		$<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

	      Note  that  tgt  is not added as a dependency of the target this
	      expression is evaluated on.

		$<TARGET_POLICY:pol>	      = '1' if the policy was NEW when the 'head' target was created, else '0'.	 If the policy was not set, the warning message for the policy will be emitted.	 This generator expression only works for a subset of policies.
		$<INSTALL_PREFIX>	  = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

	      Boolean expressions:

		$<AND:?[,?]...>		  = '1' if all '?' are '1', else '0'
		$<OR:?[,?]...>		  = '0' if all '?' are '0', else '1'
		$<NOT:?>		  = '0' if '?' is '1', else '1'

	      where '?' is always either '0' or '1'.

	      Expressions with an implicit 'this' target:

		$<TARGET_PROPERTY:prop>	  = The value of the property prop on the target on which the generator expression is evaluated.

       add_custom_command
	      Add a custom build rule to the generated build system.

	      There are two main signatures for add_custom_command  The	 first
	      signature is for adding a custom command to produce an output.

		add_custom_command(OUTPUT output1 [output2 ...]
				   COMMAND command1 [ARGS] [args1...]
				   [COMMAND command2 [ARGS] [args2...] ...]
				   [MAIN_DEPENDENCY depend]
				   [DEPENDS [depends...]]
				   [IMPLICIT_DEPENDS <lang1> depend1
						    [<lang2> depend2] ...]
				   [WORKING_DIRECTORY dir]
				   [COMMENT comment] [VERBATIM] [APPEND])

	      This  defines a command to generate specified OUTPUT file(s).  A
	      target created in the same directory (CMakeLists.txt file)  that
	      specifies	 any  output of the custom command as a source file is
	      given a rule to generate the file using  the  command  at	 build
	      time.   Do not list the output in more than one independent tar‐
	      get that may build in parallel or the two instances of the  rule
	      may conflict (instead use add_custom_target to drive the command
	      and make the other targets depend on that one).	If  an	output
	      name  is	a relative path it will be interpreted relative to the
	      build tree directory corresponding to the current source	direc‐
	      tory.  Note  that	 MAIN_DEPENDENCY is completely optional and is
	      used as a suggestion to visual studio about where	 to  hang  the
	      custom  command.	In makefile terms this creates a new target in
	      the following form:

		OUTPUT: MAIN_DEPENDENCY DEPENDS
			COMMAND

	      If more than one command is specified they will be  executed  in
	      order.  The optional ARGS argument is for backward compatibility
	      and will be ignored.

	      The second signature adds a custom command to a target such as a
	      library  or  executable. This is useful for performing an opera‐
	      tion before or after building the target.	 The  command  becomes
	      part  of the target and will only execute when the target itself
	      is built.	 If the target is already built, the command will  not
	      execute.

		add_custom_command(TARGET target
				   PRE_BUILD | PRE_LINK | POST_BUILD
				   COMMAND command1 [ARGS] [args1...]
				   [COMMAND command2 [ARGS] [args2...] ...]
				   [WORKING_DIRECTORY dir]
				   [COMMENT comment] [VERBATIM])

	      This defines a new command that will be associated with building
	      the specified target. When the command will happen is determined
	      by which of the following is specified:

		PRE_BUILD - run before all other dependencies
		PRE_LINK - run after other dependencies
		POST_BUILD - run after the target has been built

	      Note  that the PRE_BUILD option is only supported on Visual Stu‐
	      dio 7 or later. For  all	other  generators  PRE_BUILD  will  be
	      treated as PRE_LINK.

	      If  WORKING_DIRECTORY  is specified the command will be executed
	      in the directory given. If it is a  relative  path  it  will  be
	      interpreted  relative  to the build tree directory corresponding
	      to the current source directory. If COMMENT is  set,  the	 value
	      will  be displayed as a message before the commands are executed
	      at build time. If APPEND is specified the	 COMMAND  and  DEPENDS
	      option  values  are appended to the custom command for the first
	      output specified. There must have already been a	previous  call
	      to  this	command	 with  the  same  output.  The	COMMENT, WORK‐
	      ING_DIRECTORY, and MAIN_DEPENDENCY options are currently ignored
	      when APPEND is given, but may be used in the future.

	      If  VERBATIM is given then all arguments to the commands will be
	      escaped properly for the build tool so that the invoked  command
	      receives	each  argument	unchanged.   Note  that	 one  level of
	      escapes is still used by the  CMake  language  processor	before
	      add_custom_command  even	sees the arguments. Use of VERBATIM is
	      recommended as it enables correct behavior. When VERBATIM is not
	      given the behavior is platform specific because there is no pro‐
	      tection of tool-specific special characters.

	      If the output of the custom command is not actually created as a
	      file   on	  disk	 it   should   be   marked  as	SYMBOLIC  with
	      SET_SOURCE_FILES_PROPERTIES.

	      The IMPLICIT_DEPENDS option requests scanning of implicit depen‐
	      dencies of an input file.	 The language given specifies the pro‐
	      gramming language whose corresponding dependency scanner	should
	      be  used.	  Currently  only C and CXX language scanners are sup‐
	      ported. The language has to be specified for every file  in  the
	      IMPLICIT_DEPENDS list. Dependencies discovered from the scanning
	      are added to those of the custom command at  build  time.	  Note
	      that the IMPLICIT_DEPENDS option is currently supported only for
	      Makefile generators and will be ignored by other generators.

	      If COMMAND specifies an executable target (created  by  ADD_EXE‐
	      CUTABLE)	it  will  automatically be replaced by the location of
	      the executable created  at  build	 time.	 Additionally  a  tar‐
	      get-level dependency will be added so that the executable target
	      will be built before any target using this custom command.  How‐
	      ever  this does NOT add a file-level dependency that would cause
	      the custom command to re-run whenever the executable  is	recom‐
	      piled.

	      Arguments	 to  COMMAND  may use "generator expressions" with the
	      syntax "$<...>".	Generator  expressions	are  evaluated	during
	      build  system generation to produce information specific to each
	      build configuration.  Valid expressions are:

		$<0:...>		  = empty string (ignores "...")
		$<1:...>		  = content of "..."
		$<CONFIG:cfg>		  = '1' if config is "cfg", else '0'
		$<CONFIGURATION>	  = configuration name
		$<BOOL:...>		  = '1' if the '...' is true, else '0'
		$<STREQUAL:a,b>		  = '1' if a is STREQUAL b, else '0'
		$<ANGLE-R>		  = A literal '>'. Used to compare strings which contain a '>' for example.
		$<COMMA>		  = A literal ','. Used to compare strings which contain a ',' for example.
		$<SEMICOLON>		  = A literal ';'. Used to prevent list expansion on an argument with ';'.
		$<JOIN:list,...>	  = joins the list with the content of "..."
		$<TARGET_NAME:...>	  = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.	The '...' must be a literal name of a target- it may not contain generator expressions.
		$<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
		$<BUILD_INTERFACE:...>	  = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
		$<C_COMPILER_ID>	  = The CMake-id of the C compiler used.
		$<C_COMPILER_ID:comp>	  = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
		$<CXX_COMPILER_ID>	  = The CMake-id of the CXX compiler used.
		$<CXX_COMPILER_ID:comp>	  = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
		$<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
		$<VERSION_LESS:v1,v2>	  = '1' if v1 is a version less than v2, else '0'.
		$<VERSION_EQUAL:v1,v2>	  = '1' if v1 is the same version as v2, else '0'.
		$<C_COMPILER_VERSION>	  = The version of the C compiler used.
		$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
		$<CXX_COMPILER_VERSION>	  = The version of the CXX compiler used.
		$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
		$<TARGET_FILE:tgt>	  = main file (.exe, .so.1.2, .a)
		$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
		$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

	      where "tgt" is the name of a target.   Target  file  expressions
	      produce a full path, but _DIR and _NAME versions can produce the
	      directory and file name components:

		$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
		$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
		$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

		$<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

	      Note that tgt is not added as a dependency of  the  target  this
	      expression is evaluated on.

		$<TARGET_POLICY:pol>	      = '1' if the policy was NEW when the 'head' target was created, else '0'.	 If the policy was not set, the warning message for the policy will be emitted.	 This generator expression only works for a subset of policies.
		$<INSTALL_PREFIX>	  = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

	      Boolean expressions:

		$<AND:?[,?]...>		  = '1' if all '?' are '1', else '0'
		$<OR:?[,?]...>		  = '0' if all '?' are '0', else '1'
		$<NOT:?>		  = '0' if '?' is '1', else '1'

	      where '?' is always either '0' or '1'.

	      Expressions with an implicit 'this' target:

		$<TARGET_PROPERTY:prop>	  = The value of the property prop on the target on which the generator expression is evaluated.

	      References  to  target names in generator expressions imply tar‐
	      get-level dependencies, but NOT file-level  dependencies.	  List
	      target names with the DEPENDS option to add file dependencies.

	      The DEPENDS option specifies files on which the command depends.
	      If any dependency is an OUTPUT of another custom command in  the
	      same  directory (CMakeLists.txt file) CMake automatically brings
	      the other custom command into the target in which	 this  command
	      is  built.   If  DEPENDS	is  not specified the command will run
	      whenever the OUTPUT is missing; if the command does not actually
	      create  the  OUTPUT  then	 the rule will always run.  If DEPENDS
	      specifies any target  (created  by  an  ADD_*  command)  a  tar‐
	      get-level dependency is created to make sure the target is built
	      before any target using this custom command.   Additionally,  if
	      the  target  is an executable or library a file-level dependency
	      is created to cause the custom command to	 re-run	 whenever  the
	      target is recompiled.

       add_custom_target
	      Add a target with no output so it will always be built.

		add_custom_target(Name [ALL] [command1 [args1...]]
				  [COMMAND command2 [args2...] ...]
				  [DEPENDS depend depend depend ... ]
				  [WORKING_DIRECTORY dir]
				  [COMMENT comment] [VERBATIM]
				  [SOURCES src1 [src2...]])

	      Adds  a  target with the given name that executes the given com‐
	      mands. The target has no output file and	is  ALWAYS  CONSIDERED
	      OUT  OF  DATE even if the commands try to create a file with the
	      name of the target. Use ADD_CUSTOM_COMMAND to  generate  a  file
	      with dependencies. By default nothing depends on the custom tar‐
	      get. Use ADD_DEPENDENCIES to add dependencies to or  from	 other
	      targets.	If  the ALL option is specified it indicates that this
	      target should be added to the default build target  so  that  it
	      will  be	run every time (the command cannot be called ALL). The
	      command and arguments are optional and if not specified an empty
	      target  will  be	created. If WORKING_DIRECTORY is set, then the
	      command will be run in that directory. If it is a relative  path
	      it will be interpreted relative to the build tree directory cor‐
	      responding to the current source directory. If COMMENT  is  set,
	      the value will be displayed as a message before the commands are
	      executed at build time. Dependencies  listed  with  the  DEPENDS
	      argument may reference files and outputs of custom commands cre‐
	      ated with add_custom_command() in	 the  same  directory  (CMake‐
	      Lists.txt file).

	      If  VERBATIM is given then all arguments to the commands will be
	      escaped properly for the build tool so that the invoked  command
	      receives	each  argument	unchanged.   Note  that	 one  level of
	      escapes is still used by the  CMake  language  processor	before
	      add_custom_target	 even  sees  the arguments. Use of VERBATIM is
	      recommended as it enables correct behavior. When VERBATIM is not
	      given the behavior is platform specific because there is no pro‐
	      tection of tool-specific special characters.

	      The SOURCES option  specifies  additional	 source	 files	to  be
	      included	in  the custom target.	Specified source files will be
	      added to IDE project files for convenience in  editing  even  if
	      they have not build rules.

       add_definitions
	      Adds -D define flags to the compilation of source files.

		add_definitions(-DFOO -DBAR ...)

	      Adds  flags to the compiler command line for sources in the cur‐
	      rent directory and below.	 This command can be used to  add  any
	      flags,  but it was originally intended to add preprocessor defi‐
	      nitions.	Flags beginning in -D or /D that look like  preproces‐
	      sor  definitions	are automatically added to the COMPILE_DEFINI‐
	      TIONS property for  the  current	directory.   Definitions  with
	      non-trivial  values  may	be left in the set of flags instead of
	      being converted for reasons  of  backwards  compatibility.   See
	      documentation  of	 the  directory,  target, and source file COM‐
	      PILE_DEFINITIONS properties for details on  adding  preprocessor
	      definitions to specific scopes and configurations.

       add_dependencies
	      Add a dependency between top-level targets.

		add_dependencies(target-name depend-target1
				 depend-target2 ...)

	      Make  a  top-level  target depend on other top-level targets.  A
	      top-level target is one created by ADD_EXECUTABLE,  ADD_LIBRARY,
	      or ADD_CUSTOM_TARGET.  Adding dependencies with this command can
	      be used to make sure one target is built before another  target.
	      Dependencies  added  to  an IMPORTED target are followed transi‐
	      tively in its place since the target itself does not build.  See
	      the  DEPENDS  option of ADD_CUSTOM_TARGET and ADD_CUSTOM_COMMAND
	      for adding file-level dependencies in  custom  rules.   See  the
	      OBJECT_DEPENDS  option  in  SET_SOURCE_FILES_PROPERTIES  to  add
	      file-level dependencies to object files.

       add_executable
	      Add an executable to the	project	 using	the  specified	source
	      files.

		add_executable(<name> [WIN32] [MACOSX_BUNDLE]
			       [EXCLUDE_FROM_ALL]
			       source1 source2 ... sourceN)

	      Adds  an	executable  target  called <name> to be built from the
	      source files listed in the command invocation.  The <name>  cor‐
	      responds	to the logical target name and must be globally unique
	      within a project.	 The actual file name of the executable	 built
	      is constructed based on conventions of the native platform (such
	      as <name>.exe or just <name>).

	      By default the executable file will be created in the build tree
	      directory	 corresponding	to  the source tree directory in which
	      the command was invoked.	See documentation of the  RUNTIME_OUT‐
	      PUT_DIRECTORY target property to change this location.  See doc‐
	      umentation of the OUTPUT_NAME  target  property  to  change  the
	      <name> part of the final file name.

	      If  WIN32	 is given the property WIN32_EXECUTABLE will be set on
	      the target created.  See documentation of that  target  property
	      for details.

	      If MACOSX_BUNDLE is given the corresponding property will be set
	      on the created target.  See documentation of  the	 MACOSX_BUNDLE
	      target property for details.

	      If  EXCLUDE_FROM_ALL is given the corresponding property will be
	      set  on  the  created  target.	See   documentation   of   the
	      EXCLUDE_FROM_ALL target property for details.

	      The  add_executable  command can also create IMPORTED executable
	      targets using this signature:

		add_executable(<name> IMPORTED [GLOBAL])

	      An IMPORTED executable  target  references  an  executable  file
	      located  outside	the  project.  No rules are generated to build
	      it.  The target name has scope in the directory in which	it  is
	      created and below, but the GLOBAL option extends visibility.  It
	      may be referenced like any  target  built	 within	 the  project.
	      IMPORTED	executables  are  useful for convenient reference from
	      commands like add_custom_command.	 Details  about	 the  imported
	      executable are specified by setting properties whose names begin
	      in  "IMPORTED_".	 The   most   important	  such	 property   is
	      IMPORTED_LOCATION	   (and	   its	  per-configuration    version
	      IMPORTED_LOCATION_<CONFIG>) which specifies the location of  the
	      main   executable	 file  on  disk.   See	documentation  of  the
	      IMPORTED_* properties for more information.

	      The signature

		add_executable(<name> ALIAS <target>)

	      creates an alias, such that <name> can be used to refer to <tar‐
	      get>  in subsequent commands.  The <name> does not appear in the
	      generated buildsystem as a make target.  The <target> may not be
	      an  IMPORTED  target  or an ALIAS.  Alias targets can be used as
	      linkable targets, targets to read properties  from,  executables
	      for custom commands and custom targets.  They can also be tested
	      for existance  with  the	regular	 if(TARGET)  subcommand.   The
	      <name>  may  not	be used to modify properties of <target>, that
	      is, it may not be used as the operand of set_property,  set_tar‐
	      get_properties,  target_link_libraries etc.  An ALIAS target may
	      not be installed of exported.

       add_library
	      Add a library to the project using the specified source files.

		add_library(<name> [STATIC | SHARED | MODULE]
			    [EXCLUDE_FROM_ALL]
			    source1 source2 ... sourceN)

	      Adds a library target called <name> to be built from the	source
	      files  listed in the command invocation.	The <name> corresponds
	      to the logical target name and must be globally unique within  a
	      project.	 The  actual  file  name  of the library built is con‐
	      structed based on conventions of the native  platform  (such  as
	      lib<name>.a or <name>.lib).

	      STATIC,  SHARED,	or  MODULE may be given to specify the type of
	      library to be created.  STATIC libraries are archives of	object
	      files  for use when linking other targets.  SHARED libraries are
	      linked dynamically and loaded at runtime.	 MODULE libraries  are
	      plugins that are not linked into other targets but may be loaded
	      dynamically at runtime using dlopen-like functionality.	If  no
	      type  is	given explicitly the type is STATIC or SHARED based on
	      whether the current value of the variable	 BUILD_SHARED_LIBS  is
	      true.   For  SHARED  and	MODULE libraries the POSITION_INDEPEN‐
	      DENT_CODE target property is set to TRUE automatically.

	      By default the library file will be created in  the  build  tree
	      directory	 corresponding	to  the source tree directory in which
	      the command was invoked.	See documentation of the  ARCHIVE_OUT‐
	      PUT_DIRECTORY,	LIBRARY_OUTPUT_DIRECTORY,   and	  RUNTIME_OUT‐
	      PUT_DIRECTORY target properties to change	 this  location.   See
	      documentation  of	 the OUTPUT_NAME target property to change the
	      <name> part of the final file name.

	      If EXCLUDE_FROM_ALL is given the corresponding property will  be
	      set   on	 the   created	 target.   See	documentation  of  the
	      EXCLUDE_FROM_ALL target property for details.

	      The add_library command can also create IMPORTED library targets
	      using this signature:

		add_library(<name> <SHARED|STATIC|MODULE|UNKNOWN> IMPORTED
			    [GLOBAL])

	      An  IMPORTED  library  target  references a library file located
	      outside the project.  No rules are generated to build  it.   The
	      target  name  has	 scope in the directory in which it is created
	      and below, but the GLOBAL option extends visibility.  It may  be
	      referenced  like	any target built within the project.  IMPORTED
	      libraries are useful for convenient reference from commands like
	      target_link_libraries.   Details	about the imported library are
	      specified	 by  setting   properties   whose   names   begin   in
	      "IMPORTED_".  The most important such property is IMPORTED_LOCA‐
	      TION (and its per-configuration version  IMPORTED_LOCATION_<CON‐
	      FIG>)  which  specifies the location of the main library file on
	      disk.  See documentation of the IMPORTED_* properties  for  more
	      information.

	      The signature

		add_library(<name> OBJECT <src>...)

	      creates  a  special  "object library" target.  An object library
	      compiles source files but does not archive or link their	object
	      files   into  a  library.	  Instead  other  targets  created  by
	      add_library or add_executable may reference the objects using an
	      expression  of  the  form	 $<TARGET_OBJECTS:objlib> as a source,
	      where "objlib" is the object library name.  For example:

		add_library(... $<TARGET_OBJECTS:objlib> ...)
		add_executable(... $<TARGET_OBJECTS:objlib> ...)

	      will include objlib's object files in  a	library	 and  an  exe‐
	      cutable  along  with  those  compiled  from  their  own sources.
	      Object libraries may contain only	 sources  (and	headers)  that
	      compile  to object files.	 They may contain custom commands gen‐
	      erating such sources, but not PRE_BUILD, PRE_LINK, or POST_BUILD
	      commands.	   Object  libraries  cannot  be  imported,  exported,
	      installed, or linked.  Some native build systems	may  not  like
	      targets that have only object files, so consider adding at least
	      one real source  file  to	 any  target  that  references	$<TAR‐
	      GET_OBJECTS:objlib>.

	      The signature

		add_library(<name> ALIAS <target>)

	      creates an alias, such that <name> can be used to refer to <tar‐
	      get> in subsequent commands.  The <name> does not appear in  the
	      generated buildsystem as a make target.  The <target> may not be
	      an IMPORTED target or an ALIAS.  Alias targets can  be  used  as
	      linkable	targets,  targets  to  read properties from.  They can
	      also be tested for existance with the regular if(TARGET) subcom‐
	      mand.   The <name> may not be used to modify properties of <tar‐
	      get>, that is, it may not be used as the	operand	 of  set_prop‐
	      erty,   set_target_properties,  target_link_libraries  etc.   An
	      ALIAS target may not be installed of exported.

       add_subdirectory
	      Add a subdirectory to the build.

		add_subdirectory(source_dir [binary_dir]
				 [EXCLUDE_FROM_ALL])

	      Add a subdirectory to the build. The  source_dir	specifies  the
	      directory	 in which the source CMakeLists.txt and code files are
	      located. If it is a relative path	 it  will  be  evaluated  with
	      respect to the current directory (the typical usage), but it may
	      also be an absolute path. The binary_dir specifies the directory
	      in  which to place the output files. If it is a relative path it
	      will be evaluated with respect to the current output  directory,
	      but it may also be an absolute path. If binary_dir is not speci‐
	      fied, the value of source_dir,  before  expanding	 any  relative
	      path,  will be used (the typical usage). The CMakeLists.txt file
	      in the specified source directory will be processed  immediately
	      by  CMake	 before processing in the current input file continues
	      beyond this command.

	      If the EXCLUDE_FROM_ALL argument is provided then targets in the
	      subdirectory  will not be included in the ALL target of the par‐
	      ent directory by default, and will be excluded from IDE  project
	      files.  Users must explicitly build targets in the subdirectory.
	      This is meant for use when the subdirectory contains a  separate
	      part  of the project that is useful but not necessary, such as a
	      set of examples.	Typically the subdirectory should contain  its
	      own  project()  command  invocation  so that a full build system
	      will be generated in the subdirectory (such as a VS IDE solution
	      file).   Note  that  inter-target	 dependencies  supercede  this
	      exclusion.  If a target built by the parent project depends on a
	      target in the subdirectory, the dependee target will be included
	      in the parent project build system to satisfy the dependency.

       add_test
	      Add a test to the project with the specified arguments.

		add_test(testname Exename arg1 arg2 ... )

	      If the ENABLE_TESTING command has been run, this command adds  a
	      test  target to the current directory. If ENABLE_TESTING has not
	      been run, this command does nothing.  The tests are run  by  the
	      testing  subsystem by executing Exename with the specified argu‐
	      ments.  Exename can  be  either  an  executable  built  by  this
	      project  or  an arbitrary executable on the system (like tclsh).
	      The test will be run with the current working directory  set  to
	      the  CMakeList.txt  files	 corresponding directory in the binary
	      tree.

		add_test(NAME <name> [CONFIGURATIONS [Debug|Release|...]]
			 [WORKING_DIRECTORY dir]
			 COMMAND <command> [arg1 [arg2 ...]])

	      Add a test called <name>.	 The test name may not contain spaces,
	      quotes, or other characters special in CMake syntax.  If COMMAND
	      specifies an executable target (created  by  add_executable)  it
	      will automatically be replaced by the location of the executable
	      created at build time.  If a CONFIGURATIONS option is given then
	      the  test	 will  be  executed only when testing under one of the
	      named configurations.  If a WORKING_DIRECTORY  option  is	 given
	      then the test will be executed in the given directory.

	      Arguments after COMMAND may use "generator expressions" with the
	      syntax "$<...>".	Generator  expressions	are  evaluated	during
	      build  system generation to produce information specific to each
	      build configuration.  Valid expressions are:

		$<0:...>		  = empty string (ignores "...")
		$<1:...>		  = content of "..."
		$<CONFIG:cfg>		  = '1' if config is "cfg", else '0'
		$<CONFIGURATION>	  = configuration name
		$<BOOL:...>		  = '1' if the '...' is true, else '0'
		$<STREQUAL:a,b>		  = '1' if a is STREQUAL b, else '0'
		$<ANGLE-R>		  = A literal '>'. Used to compare strings which contain a '>' for example.
		$<COMMA>		  = A literal ','. Used to compare strings which contain a ',' for example.
		$<SEMICOLON>		  = A literal ';'. Used to prevent list expansion on an argument with ';'.
		$<JOIN:list,...>	  = joins the list with the content of "..."
		$<TARGET_NAME:...>	  = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.	The '...' must be a literal name of a target- it may not contain generator expressions.
		$<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
		$<BUILD_INTERFACE:...>	  = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
		$<C_COMPILER_ID>	  = The CMake-id of the C compiler used.
		$<C_COMPILER_ID:comp>	  = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
		$<CXX_COMPILER_ID>	  = The CMake-id of the CXX compiler used.
		$<CXX_COMPILER_ID:comp>	  = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
		$<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
		$<VERSION_LESS:v1,v2>	  = '1' if v1 is a version less than v2, else '0'.
		$<VERSION_EQUAL:v1,v2>	  = '1' if v1 is the same version as v2, else '0'.
		$<C_COMPILER_VERSION>	  = The version of the C compiler used.
		$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
		$<CXX_COMPILER_VERSION>	  = The version of the CXX compiler used.
		$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
		$<TARGET_FILE:tgt>	  = main file (.exe, .so.1.2, .a)
		$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
		$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

	      where "tgt" is the name of a target.   Target  file  expressions
	      produce a full path, but _DIR and _NAME versions can produce the
	      directory and file name components:

		$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
		$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
		$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

		$<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

	      Note that tgt is not added as a dependency of  the  target  this
	      expression is evaluated on.

		$<TARGET_POLICY:pol>	      = '1' if the policy was NEW when the 'head' target was created, else '0'.	 If the policy was not set, the warning message for the policy will be emitted.	 This generator expression only works for a subset of policies.
		$<INSTALL_PREFIX>	  = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

	      Boolean expressions:

		$<AND:?[,?]...>		  = '1' if all '?' are '1', else '0'
		$<OR:?[,?]...>		  = '0' if all '?' are '0', else '1'
		$<NOT:?>		  = '0' if '?' is '1', else '1'

	      where '?' is always either '0' or '1'.

	      Example usage:

		add_test(NAME mytest
			 COMMAND testDriver --config $<CONFIGURATION>
					    --exe $<TARGET_FILE:myexe>)

	      This  creates  a	test  "mytest" whose command runs a testDriver
	      tool passing the configuration name and the  full	 path  to  the
	      executable file produced by target "myexe".

       aux_source_directory
	      Find all source files in a directory.

		aux_source_directory(<dir> <variable>)

	      Collects	the  names  of	all  the source files in the specified
	      directory and stores the list in the <variable> provided.	  This
	      command  is  intended  to	 be used by projects that use explicit
	      template instantiation.  Template	 instantiation	files  can  be
	      stored in a "Templates" subdirectory and collected automatically
	      using this command to avoid manually listing all instantiations.

	      It is tempting to use this command to avoid writing the list  of
	      source  files  for  a  library or executable target.  While this
	      seems to work, there is no way for CMake	to  generate  a	 build
	      system  that  knows when a new source file has been added.  Nor‐
	      mally the generated build system knows when it  needs  to	 rerun
	      CMake  because  the CMakeLists.txt file is modified to add a new
	      source.  When the source is just added to the directory  without
	      modifying	 this  file, one would have to manually rerun CMake to
	      generate a build system incorporating the new file.

       break  Break from an enclosing foreach or while loop.

		break()

	      Breaks from an enclosing foreach loop or while loop

       build_command
	      Get the command line to build this project.

		build_command(<variable>
			      [CONFIGURATION <config>]
			      [PROJECT_NAME <projname>]
			      [TARGET <target>])

	      Sets the given <variable> to a  string  containing  the  command
	      line  for	 building  one	configuration of a target in a project
	      using the build tool appropriate for the	current	 CMAKE_GENERA‐
	      TOR.

	      If  CONFIGURATION is omitted, CMake chooses a reasonable default
	      value  for  multi-configuration  generators.   CONFIGURATION  is
	      ignored for single-configuration generators.

	      If  PROJECT_NAME	is  omitted,  the  resulting command line will
	      build the top level PROJECT in the current build tree.

	      If TARGET is omitted, the	 resulting  command  line  will	 build
	      everything, effectively using build target 'all' or 'ALL_BUILD'.

		build_command(<cachevariable> <makecommand>)

	      This  second  signature  is  deprecated, but still available for
	      backwards compatibility. Use the first signature instead.

	      Sets the given <cachevariable> to a string containing  the  com‐
	      mand to build this project from the root of the build tree using
	      the build tool given by <makecommand>.  <makecommand> should  be
	      the  full	 path  to msdev, devenv, nmake, make or one of the end
	      user build tools.

       cmake_host_system_information
	      Query host system specific information.

		cmake_host_system_information(RESULT <variable> QUERY <key> ...)

	      Queries system information of the host  system  on  which	 cmake
	      runs.  One  or more <key> can be provided to select the informa‐
	      tion to be queried. The list of  queried	values	is  stored  in
	      <variable>.

	      <key> can be one of the following values:

		NUMBER_OF_LOGICAL_CORES	  = Number of logical cores.
		NUMBER_OF_PHYSICAL_CORES  = Number of physical cores.
		HOSTNAME		  = Hostname.
		FQDN			  = Fully qualified domain name.
		TOTAL_VIRTUAL_MEMORY	  = Total virtual memory in megabytes.
		AVAILABLE_VIRTUAL_MEMORY  = Available virtual memory in megabytes.
		TOTAL_PHYSICAL_MEMORY	  = Total physical memory in megabytes.
		AVAILABLE_PHYSICAL_MEMORY = Available physical memory in megabytes.

       cmake_minimum_required
	      Set the minimum required version of cmake for a project.

		cmake_minimum_required(VERSION major[.minor[.patch[.tweak]]]
				       [FATAL_ERROR])

	      If  the  current version of CMake is lower than that required it
	      will stop processing the project and report an  error.   When  a
	      version  higher  than  2.4  is  specified the command implicitly
	      invokes

		cmake_policy(VERSION major[.minor[.patch[.tweak]]])

	      which sets the cmake policy version level to the version	speci‐
	      fied.  When version 2.4 or lower is given the command implicitly
	      invokes

		cmake_policy(VERSION 2.4)

	      which enables compatibility features for CMake 2.4 and lower.

	      The FATAL_ERROR option is accepted but ignored by CMake 2.6  and
	      higher.	It should be specified so CMake versions 2.4 and lower
	      fail with an error instead of just a warning.

       cmake_policy
	      Manage CMake Policy settings.

	      As CMake evolves it is sometimes necessary  to  change  existing
	      behavior	in  order  to  fix  bugs or improve implementations of
	      existing features.  The CMake Policy mechanism  is  designed  to
	      help  keep  existing  projects building as new versions of CMake
	      introduce changes in  behavior.	Each  new  policy  (behavioral
	      change)  is  given  an  identifier of the form "CMP<NNNN>" where
	      "<NNNN>" is an integer  index.   Documentation  associated  with
	      each  policy  describes  the OLD and NEW behavior and the reason
	      the policy was introduced.  Projects  may	 set  each  policy  to
	      select  the  desired  behavior.	When CMake needs to know which
	      behavior to use  it  checks  for	a  setting  specified  by  the
	      project.	If no setting is available the OLD behavior is assumed
	      and a warning is produced requesting that the policy be set.

	      The cmake_policy command is used to set policies to OLD  or  NEW
	      behavior.	  While setting policies individually is supported, we
	      encourage projects to set policies based on CMake versions.

		cmake_policy(VERSION major.minor[.patch[.tweak]])

	      Specify that the current CMake list  file	 is  written  for  the
	      given  version  of CMake.	 All policies introduced in the speci‐
	      fied version or earlier will be set to use  NEW  behavior.   All
	      policies	introduced  after  the specified version will be unset
	      (unless variable CMAKE_POLICY_DEFAULT_CMP<NNNN> sets a default).
	      This effectively requests behavior preferred as of a given CMake
	      version and tells newer CMake versions to warn about  their  new
	      policies.	  The policy version specified must be at least 2.4 or
	      the command will report an error.	 In order to get compatibility
	      features	supporting versions earlier than 2.4 see documentation
	      of policy CMP0001.

		cmake_policy(SET CMP<NNNN> NEW)
		cmake_policy(SET CMP<NNNN> OLD)

	      Tell CMake to use the OLD or NEW behavior for  a	given  policy.
	      Projects	depending  on  the  old behavior of a given policy may
	      silence a policy warning by setting the  policy  state  to  OLD.
	      Alternatively  one  may  fix  the	 project  to work with the new
	      behavior and set the policy state to NEW.

		cmake_policy(GET CMP<NNNN> <variable>)

	      Check whether a given policy is set to OLD or NEW behavior.  The
	      output  variable	value  will be "OLD" or "NEW" if the policy is
	      set, and empty otherwise.

	      CMake keeps policy settings on a stack, so changes made  by  the
	      cmake_policy  command  affect  only the top of the stack.	 A new
	      entry on the policy stack is managed automatically for each sub‐
	      directory	 to protect its parents and siblings.  CMake also man‐
	      ages a new entry for scripts loaded by include() and  find_pack‐
	      age()  commands  except  when  invoked  with the NO_POLICY_SCOPE
	      option (see also policy CMP0011).	 The cmake_policy command pro‐
	      vides an interface to manage custom entries on the policy stack:

		cmake_policy(PUSH)
		cmake_policy(POP)

	      Each  PUSH  must have a matching POP to erase any changes.  This
	      is useful to make temporary changes to policy settings.

	      Functions and macros record policy settings when they  are  cre‐
	      ated  and use the pre-record policies when they are invoked.  If
	      the function or macro implementation sets policies, the  changes
	      automatically  propagate up through callers until they reach the
	      closest nested policy stack entry.

       configure_file
	      Copy a file to another location and modify its contents.

		configure_file(<input> <output>
			       [COPYONLY] [ESCAPE_QUOTES] [@ONLY]
			       [NEWLINE_STYLE [UNIX|DOS|WIN32|LF|CRLF] ])

	      Copies a file <input> to file <output> and substitutes  variable
	      values referenced in the file content.  If <input> is a relative
	      path it is evaluated with respect to the current	source	direc‐
	      tory.  The <input> must be a file, not a directory.  If <output>
	      is a relative path it is evaluated with respect to  the  current
	      binary  directory.   If <output> names an existing directory the
	      input file is placed in that directory with its original name.

	      If the <input> file is modified the  build  system  will	re-run
	      CMake  to	 re-configure  the  file and generate the build system
	      again.

	      This command replaces any variables in the input file referenced
	      as ${VAR} or @VAR@ with their values as determined by CMake.  If
	      a variable is not defined, it will be replaced with nothing.  If
	      COPYONLY	is  specified,	then  no  variable expansion will take
	      place.  If  ESCAPE_QUOTES	 is  specified	then  any  substituted
	      quotes  will  be	C-style	 escaped.  The file will be configured
	      with the current values of CMake variables. If @ONLY  is	speci‐
	      fied,  only  variables  of  the  form @VAR@ will be replaced and
	      ${VAR} will be ignored.  This is useful for configuring  scripts
	      that use ${VAR}.

	      Input  file  lines  of  the  form "#cmakedefine VAR ..." will be
	      replaced with either "#define VAR ..." or	 "/*  #undef  VAR  */"
	      depending	 on  whether VAR is set in CMake to any value not con‐
	      sidered a false constant by the if() command. (Content of "...",
	      if  any,	is  processed  as above.) Input file lines of the form
	      "#cmakedefine01 VAR" will be replaced with either	 "#define  VAR
	      1" or "#define VAR 0" similarly.

	      With NEWLINE_STYLE the line ending could be adjusted:

		  'UNIX' or 'LF' for \n, 'DOS', 'WIN32' or 'CRLF' for \r\n.

	      COPYONLY must not be used with NEWLINE_STYLE.

       create_test_sourcelist
	      Create a test driver and source list for building test programs.

		create_test_sourcelist(sourceListName driverName
				       test1 test2 test3
				       EXTRA_INCLUDE include.h
				       FUNCTION function)

	      A	 test driver is a program that links together many small tests
	      into a single executable.	 This is useful when  building	static
	      executables  with	 large	libraries to shrink the total required
	      size.  The list of source files needed to build the test	driver
	      will  be	in sourceListName.  DriverName is the name of the test
	      driver program.  The rest of the arguments consist of a list  of
	      test source files, can be semicolon separated.  Each test source
	      file should have a function in it that is the same name  as  the
	      file  with  no  extension	 (foo.cxx  should  have	 int  foo(int,
	      char*[]);) DriverName will be able to call each of the tests  by
	      name  on	the  command line. If EXTRA_INCLUDE is specified, then
	      the next argument is included into the generated file. If	 FUNC‐
	      TION is specified, then the next argument is taken as a function
	      name that is passed a pointer to ac and av.  This can be used to
	      add  extra command line processing to each test. The cmake vari‐
	      able CMAKE_TESTDRIVER_BEFORE_TESTMAIN can be set	to  have  code
	      that  will be placed directly before calling the test main func‐
	      tion.   CMAKE_TESTDRIVER_AFTER_TESTMAIN can be set to have  code
	      that  will  be  placed  directly after the call to the test main
	      function.

       define_property
	      Define and document custom properties.

		define_property(<GLOBAL | DIRECTORY | TARGET | SOURCE |
				 TEST | VARIABLE | CACHED_VARIABLE>
				 PROPERTY <name> [INHERITED]
				 BRIEF_DOCS <brief-doc> [docs...]
				 FULL_DOCS <full-doc> [docs...])

	      Define one property in a scope for use with the set_property and
	      get_property  commands.	This  is primarily useful to associate
	      documentation with property names that may be retrieved with the
	      get_property command.  The first argument determines the kind of
	      scope in which the property should be used.  It must be  one  of
	      the following:

		GLOBAL	  = associated with the global namespace
		DIRECTORY = associated with one directory
		TARGET	  = associated with one target
		SOURCE	  = associated with one source file
		TEST	  = associated with a test named with add_test
		VARIABLE  = documents a CMake language variable
		CACHED_VARIABLE = documents a CMake cache variable

	      Note  that  unlike set_property and get_property no actual scope
	      needs to be given; only the kind of scope is important.

	      The required PROPERTY option is immediately followed by the name
	      of the property being defined.

	      If the INHERITED option then the get_property command will chain
	      up to the next higher scope when the requested property  is  not
	      set  in  the scope given to the command.	DIRECTORY scope chains
	      to GLOBAL.  TARGET, SOURCE, and TEST chain to DIRECTORY.

	      The BRIEF_DOCS and FULL_DOCS options are followed by strings  to
	      be associated with the property as its brief and full documenta‐
	      tion.  Corresponding options to the  get_property	 command  will
	      retrieve the documentation.

       else   Starts the else portion of an if block.

		else(expression)

	      See the if command.

       elseif Starts the elseif portion of an if block.

		elseif(expression)

	      See the if command.

       enable_language
	      Enable a language (CXX/C/Fortran/etc)

		enable_language(<lang> [OPTIONAL] )

	      This  command  enables  support for the named language in CMake.
	      This is the same as the project command but does not create  any
	      of  the extra variables that are created by the project command.
	      Example languages are CXX, C, Fortran.

	      This command must be called in file scope,  not  in  a  function
	      call.   Furthermore,  it must be called in the highest directory
	      common to all targets using the named language directly for com‐
	      piling  sources  or indirectly through link dependencies.	 It is
	      simplest to enable all needed languages in the top-level	direc‐
	      tory of a project.

	      The  OPTIONAL keyword is a placeholder for future implementation
	      and does not currently work.

       enable_testing
	      Enable testing for current directory and below.

		enable_testing()

	      Enables testing for this directory  and  below.	See  also  the
	      add_test	command.   Note that ctest expects to find a test file
	      in the build directory root.  Therefore, this command should  be
	      in the source directory root.

	      Runs  the	 given sequence of one or more commands with the stan‐
	      dard output of each process piped to the standard input  of  the
	      next.   A	 single standard error pipe is used for all processes.
	      If WORKING_DIRECTORY is given the named directory will be set as
	      the  current working directory of the child processes.  If TIME‐
	      OUT is given the child processes will be terminated if  they  do
	      not  finish  in  the  specified number of seconds (fractions are
	      allowed).	 If RESULT_VARIABLE is given the variable will be  set
	      to contain the result of running the processes.  This will be an
	      integer return code from the last child or a  string  describing
	      an  error	 condition.   If OUTPUT_VARIABLE or ERROR_VARIABLE are
	      given the variable named will be set with the  contents  of  the
	      standard	output	and standard error pipes respectively.	If the
	      same variable is named for  both	pipes  their  output  will  be
	      merged  in  the  order produced.	If INPUT_FILE, OUTPUT_FILE, or
	      ERROR_FILE is given the file named will be attached to the stan‐
	      dard  input  of  the  first process, standard output of the last
	      process, or standard error of all	 processes  respectively.   If
	      OUTPUT_QUIET or ERROR_QUIET is given then the standard output or
	      standard error results will be quietly ignored.	If  more  than
	      one  OUTPUT_*  or	 ERROR_* option is given for the same pipe the
	      precedence is not specified.  If no OUTPUT_* or ERROR_*  options
	      are given the output will be shared with the corresponding pipes
	      of the CMake process itself.

	      The execute_process command is a newer more powerful version  of
	      exec_program,  but the old command has been kept for compatibil‐
	      ity.

       export Export targets from the build tree for use by outside projects.

		export(TARGETS [target1 [target2 [...]]] [NAMESPACE <namespace>]
		       [APPEND] FILE <filename> [EXPORT_LINK_INTERFACE_LIBRARIES])

	      Create a	file  <filename>  that	may  be	 included  by  outside
	      projects	to  import  targets  from  the current project's build
	      tree.  This is useful during cross-compiling  to	build  utility
	      executables that can run on the host platform in one project and
	      then import them into another project  being  compiled  for  the
	      target  platform.	  If the NAMESPACE option is given the <names‐
	      pace> string will be prepended to all target  names  written  to
	      the file.	 If the APPEND option is given the generated code will
	      be  appended  to	the  file  instead  of	overwriting  it.   The
	      EXPORT_LINK_INTERFACE_LIBRARIES  keyword, if present, causes the
	      contents	of  the	 properties  matching  (IMPORTED_)?LINK_INTER‐
	      FACE_LIBRARIES(_<CONFIG>)?  to  be exported, when policy CMP0022
	      is NEW.  If a library target is included in  the	export	but  a
	      target to which it links is not included the behavior is unspec‐
	      ified.

	      The file created by this command is specific to the  build  tree
	      and  should never be installed.  See the install(EXPORT) command
	      to export targets from an installation tree.

	      Do not set properties that affect the location of a target after
	      passing  it  to  this  command.	These include properties whose
	      names    match	"(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIREC‐
	      TORY)(_<CONFIG>)?", "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LAN‐
	      GUAGE".  Failure to follow this rule is not diagnosed and leaves
	      the location of the target undefined.

		export(PACKAGE <name>)

	      Store the current build directory in the CMake user package reg‐
	      istry for package <name>.	 The find_package command may consider
	      the  directory  while  searching for package <name>.  This helps
	      dependent projects find and  use	a  package  from  the  current
	      project's	 build tree without help from the user.	 Note that the
	      entry in the package registry that this  command	creates	 works
	      only   in	  conjunction	with   a  package  configuration  file
	      (<name>Config.cmake) that works with the build tree.

	      WRITE will write a message into a	 file  called  'filename'.  It
	      overwrites  the  file if it already exists, and creates the file
	      if it does not exist. (If the file is a build input, use config‐
	      ure_file to update the file only when its content changes.)

	      APPEND will write a message into a file same as WRITE, except it
	      will append it to the end of the file

	      READ will read the content of a file and store it into the vari‐
	      able. It will start at the given offset and read up to numBytes.
	      If the argument HEX is given, the binary data will be  converted
	      to  hexadecimal  representation  and  this will be stored in the
	      variable.

	      MD5, SHA1, SHA224, SHA256, SHA384, and  SHA512  will  compute  a
	      cryptographic hash of the content of a file.

	      STRINGS will parse a list of ASCII strings from a file and store
	      it in a variable. Binary data in the file are ignored.  Carriage
	      return  (CR) characters are ignored. It works also for Intel Hex
	      and Motorola S-record files, which are  automatically  converted
	      to   binary   format  when  reading  them.  Disable  this	 using
	      NO_HEX_CONVERSION.

	      LIMIT_COUNT sets	the  maximum  number  of  strings  to  return.
	      LIMIT_INPUT  sets	 the  maximum number of bytes to read from the
	      input file. LIMIT_OUTPUT sets the maximum	 number	 of  bytes  to
	      store  in	 the  output variable. LENGTH_MINIMUM sets the minimum
	      length of a string  to  return.  Shorter	strings	 are  ignored.
	      LENGTH_MAXIMUM  sets  the	 maximum length of a string to return.
	      Longer strings are split into strings no longer than the maximum
	      length.  NEWLINE_CONSUME	allows	newlines  to  be  included  in
	      strings instead of terminating them.

	      REGEX specifies a regular expression that a string must match to
	      be returned. Typical usage

		file(STRINGS myfile.txt myfile)

	      stores  a	 list in the variable "myfile" in which each item is a
	      line from the input file.

	      GLOB will generate a list of all files that match	 the  globbing
	      expressions and store it into the variable. Globbing expressions
	      are similar to regular expressions, but much simpler.  If	 RELA‐
	      TIVE  flag  is  specified for an expression, the results will be
	      returned as a relative path to the given path.  (We do not  rec‐
	      ommend  using  GLOB  to collect a list of source files from your
	      source tree.  If no CMakeLists.txt file changes when a source is
	      added  or	 removed  then	the generated build system cannot know
	      when to ask CMake to regenerate.)

	      Examples of globbing expressions include:

		 *.cxx	    - match all files with extension cxx
		 *.vt?	    - match all files with extension vta,...,vtz
		 f[3-5].txt - match files f3.txt, f4.txt, f5.txt

	      GLOB_RECURSE will generate a list similar to the	regular	 GLOB,
	      except  it  will	traverse all the subdirectories of the matched
	      directory and match the files. Subdirectories that are  symlinks
	      are  only	 traversed if FOLLOW_SYMLINKS is given or cmake policy
	      CMP0009 is not set to NEW. See cmake --help-policy  CMP0009  for
	      more information.

	      Examples of recursive globbing include:

		 /dir/*.py  - match all python files in /dir and subdirectories

	      MAKE_DIRECTORY  will create the given directories, also if their
	      parent directories don't exist yet

	      RENAME moves a file or directory within a filesystem,  replacing
	      the destination atomically.

	      REMOVE will remove the given files, also in subdirectories

	      REMOVE_RECURSE will remove the given files and directories, also
	      non-empty directories

	      RELATIVE_PATH will determine relative path from directory to the
	      given file.

	      TO_CMAKE_PATH  will  convert  path  into a cmake style path with
	      unix /.  The input can be a single path or a  system  path  like
	      "$ENV{PATH}".   Note  the	 double	 quotes	 around	 the  ENV call
	      TO_CMAKE_PATH only takes	one argument. This command  will  also
	      convert  the native list delimiters for a list of paths like the
	      PATH environment variable.

	      TO_NATIVE_PATH works just like TO_CMAKE_PATH, but	 will  convert
	      from   a	cmake style path into the native path style \ for win‐
	      dows and / for UNIX.

	      DOWNLOAD will download the given URL to the given file.  If  LOG
	      var  is  specified  a log of the download will be put in var. If
	      STATUS var is specified the status of the operation will be  put
	      in  var. The status is returned in a list of length 2. The first
	      element is the numeric return value for the operation,  and  the
	      second  element  is  a  string  value for the error. A 0 numeric
	      error means no error in the operation. If TIMEOUT time is speci‐
	      fied, the operation will timeout after time seconds, time should
	      be specified as an integer. The INACTIVITY_TIMEOUT specifies  an
	      integer  number  of seconds of inactivity after which the opera‐
	      tion should terminate. If EXPECTED_HASH ALGO=value is specified,
	      the operation will verify that the downloaded file's actual hash
	      matches the expected value, where ALGO  is  one  of  MD5,	 SHA1,
	      SHA224,  SHA256,	SHA384,	 or SHA512.  If it does not match, the
	      operation fails with an error. ("EXPECTED_MD5 sum" is short-hand
	      for  "EXPECTED_HASH  MD5=sum".)  If  SHOW_PROGRESS is specified,
	      progress information will be printed as  status  messages	 until
	      the  operation  is  complete. For https URLs CMake must be built
	      with OpenSSL.  TLS/SSL certificates are not checked by  default.
	      Set   TLS_VERIFY	 to   ON  to  check  certificates  and/or  use
	      EXPECTED_HASH to verify downloaded content.  Set	TLS_CAINFO  to
	      specify  a  custom  Certificate  Authority  file.	 If either TLS
	      option is not given CMake will check variables  CMAKE_TLS_VERIFY
	      and CMAKE_TLS_CAINFO, respectively.

	      UPLOAD  will  upload the given file to the given URL. If LOG var
	      is specified a log of the upload will be put in var.  If	STATUS
	      var is specified the status of the operation will be put in var.
	      The status is returned in a list of length 2. The first  element
	      is  the  numeric	return value for the operation, and the second
	      element is a string value for the error. A 0 numeric error means
	      no  error	 in  the  operation. If TIMEOUT time is specified, the
	      operation will timeout after time seconds, time should be speci‐
	      fied  as an integer. The INACTIVITY_TIMEOUT specifies an integer
	      number of seconds of inactivity after which the operation should
	      terminate.  If  SHOW_PROGRESS is specified, progress information
	      will be printed as status messages until the operation  is  com‐
	      plete.

	      TIMESTAMP will write a string representation of the modification
	      time of filename to variable.

	      Should the command be unable to obtain a timestamp variable will
	      be set to the empty string "".

	      See  documentation  of the string TIMESTAMP sub-command for more
	      details.

	      The file() command also provides COPY and INSTALL signatures:

		file(<COPY|INSTALL> files... DESTINATION <dir>
		     [FILE_PERMISSIONS permissions...]
		     [DIRECTORY_PERMISSIONS permissions...]
		     [NO_SOURCE_PERMISSIONS] [USE_SOURCE_PERMISSIONS]
		     [FILES_MATCHING]
		     [[PATTERN <pattern> | REGEX <regex>]
		      [EXCLUDE] [PERMISSIONS permissions...]] [...])

	      The COPY signature copies files, directories, and symlinks to  a
	      destination  folder.   Relative  input  paths are evaluated with
	      respect to the current source directory, and a relative destina‐
	      tion  is	evaluated with respect to the current build directory.
	      Copying preserves input file timestamps,	and  optimizes	out  a
	      file  if	it  exists at the destination with the same timestamp.
	      Copying preserves input permissions unless explicit  permissions
	      or  NO_SOURCE_PERMISSIONS	 are given (default is USE_SOURCE_PER‐
	      MISSIONS).  See the install(DIRECTORY) command for documentation
	      of permissions, PATTERN, REGEX, and EXCLUDE options.

	      The INSTALL signature differs slightly from COPY: it prints sta‐
	      tus messages, and NO_SOURCE_PERMISSIONS is  default.   Installa‐
	      tion  scripts generated by the install() command use this signa‐
	      ture (with some undocumented options for internal use).

	      GENERATE will  write  an	<output_file>  with  content  from  an
	      <input_file>,  or from <input_content>.  The output is generated
	      conditionally based on the content of the <condition>.  The file
	      is written at CMake generate-time and the input may contain gen‐
	      erator  expressions.    The   <condition>,   <output_file>   and
	      <input_file>  may also contain generator expressions.  The <con‐
	      dition> must evaluate to either '0' or '1'.   The	 <output_file>
	      must  evaluate  to  a  unique  name among all configurations and
	      among all invocations of file(GENERATE).

       find_file
	      Find the full path to a file.

		 find_file(<VAR> name1 [path1 path2 ...])

	      This is the short-hand signature for the command that is	suffi‐
	      cient  in	 many  cases.  It is the same as find_file(<VAR> name1
	      [PATHS path1 path2 ...])

		 find_file(
			   <VAR>
			   name | NAMES name1 [name2 ...]
			   [HINTS path1 [path2 ... ENV var]]
			   [PATHS path1 [path2 ... ENV var]]
			   [PATH_SUFFIXES suffix1 [suffix2 ...]]
			   [DOC "cache documentation string"]
			   [NO_DEFAULT_PATH]
			   [NO_CMAKE_ENVIRONMENT_PATH]
			   [NO_CMAKE_PATH]
			   [NO_SYSTEM_ENVIRONMENT_PATH]
			   [NO_CMAKE_SYSTEM_PATH]
			   [CMAKE_FIND_ROOT_PATH_BOTH |
			    ONLY_CMAKE_FIND_ROOT_PATH |
			    NO_CMAKE_FIND_ROOT_PATH]
			  )

	      This command is used to find a full path to named file. A	 cache
	      entry named by <VAR> is created to store the result of this com‐
	      mand.  If the full path to a file is found the result is	stored
	      in  the  variable and the search will not be repeated unless the
	      variable is cleared.  If nothing is found, the  result  will  be
	      <VAR>-NOTFOUND,  and the search will be attempted again the next
	      time find_file is invoked with the same variable.	 The  name  of
	      the full path to a file that is searched for is specified by the
	      names listed after the NAMES argument.   Additional search loca‐
	      tions  can be specified after the PATHS argument.	 If ENV var is
	      found in the HINTS or PATHS section the environment variable var
	      will be read and converted from a system environment variable to
	      a cmake style list of paths.  For example ENV PATH  would	 be  a
	      way  to  list  the  system path variable. The argument after DOC
	      will  be	used  for  the	documentation  string  in  the	cache.
	      PATH_SUFFIXES specifies additional subdirectories to check below
	      each search path.

	      If NO_DEFAULT_PATH is specified, then no	additional  paths  are
	      added  to	 the  search. If NO_DEFAULT_PATH is not specified, the
	      search process is as follows:

	      1. Search paths specified	 in  cmake-specific  cache  variables.
	      These  are  intended  to	be  used  on  the  command line with a
	      -DVAR=value.  This can be skipped if NO_CMAKE_PATH is passed.

		 <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
		 <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
		 CMAKE_INCLUDE_PATH
		 CMAKE_FRAMEWORK_PATH

	      2. Search paths specified in  cmake-specific  environment	 vari‐
	      ables.  These are intended to be set in the user's shell config‐
	      uration.	This can be skipped  if	 NO_CMAKE_ENVIRONMENT_PATH  is
	      passed.

		 <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
		 <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
		 CMAKE_INCLUDE_PATH
		 CMAKE_FRAMEWORK_PATH

	      3. Search the paths specified by the HINTS option.  These should
	      be paths computed by system introspection, such as a  hint  pro‐
	      vided by the location of another item already found.  Hard-coded
	      guesses should be specified with the PATHS option.

	      4. Search the standard system environment variables. This can be
	      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

		 PATH
		 INCLUDE

	      5.  Search cmake variables defined in the Platform files for the
	      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH  is
	      passed.

		 <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
		 <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
		 CMAKE_SYSTEM_INCLUDE_PATH
		 CMAKE_SYSTEM_FRAMEWORK_PATH

	      6.  Search  the  paths  specified	 by the PATHS option or in the
	      short-hand  version  of  the  command.   These   are   typically
	      hard-coded guesses.

	      On Darwin or systems supporting OS X Frameworks, the cmake vari‐
	      able    CMAKE_FIND_FRAMEWORK can be set to empty or one  of  the
	      following:

		 "FIRST"  - Try to find frameworks before standard
			    libraries or headers. This is the default on Darwin.
		 "LAST"	  - Try to find frameworks after standard
			    libraries or headers.
		 "ONLY"	  - Only try to find frameworks.
		 "NEVER" - Never try to find frameworks.

	      On  Darwin  or  systems supporting OS X Application Bundles, the
	      cmake variable CMAKE_FIND_APPBUNDLE can be set to empty  or  one
	      of the following:

		 "FIRST"  - Try to find application bundles before standard
			    programs. This is the default on Darwin.
		 "LAST"	  - Try to find application bundles after standard
			    programs.
		 "ONLY"	  - Only try to find application bundles.
		 "NEVER" - Never try to find application bundles.

	      The  CMake  variable  CMAKE_FIND_ROOT_PATH specifies one or more
	      directories to be prepended to  all  other  search  directories.
	      This  effectively "re-roots" the entire search under given loca‐
	      tions. By default it is empty.  It  is  especially  useful  when
	      cross-compiling  to  point  to  the root directory of the target
	      environment and CMake will search there too. By default at first
	      the  directories	listed	in  CMAKE_FIND_ROOT_PATH  and then the
	      non-rooted directories will be searched.	The  default  behavior
	      can  be  adjusted	 by setting CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.
	      This behavior can be manually overridden on a per-call basis. By
	      using  CMAKE_FIND_ROOT_PATH_BOTH	the  search  order  will be as
	      described	 above.	 If  NO_CMAKE_FIND_ROOT_PATH  is   used	  then
	      CMAKE_FIND_ROOT_PATH	will	  not	   be	  used.	    If
	      ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted direc‐
	      tories will be searched.

	      The  default  search  order  is  designed to be most-specific to
	      least-specific for common use cases.  Projects may override  the
	      order by simply calling the command multiple times and using the
	      NO_* options:

		 find_file(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
		 find_file(<VAR> NAMES name)

	      Once one of the calls succeeds the result variable will  be  set
	      and stored in the cache so that no call will search again.

       find_library
	      Find a library.

		 find_library(<VAR> name1 [path1 path2 ...])

	      This  is the short-hand signature for the command that is suffi‐
	      cient in many cases.  It is the same as find_library(<VAR> name1
	      [PATHS path1 path2 ...])

		 find_library(
			   <VAR>
			   name | NAMES name1 [name2 ...] [NAMES_PER_DIR]
			   [HINTS path1 [path2 ... ENV var]]
			   [PATHS path1 [path2 ... ENV var]]
			   [PATH_SUFFIXES suffix1 [suffix2 ...]]
			   [DOC "cache documentation string"]
			   [NO_DEFAULT_PATH]
			   [NO_CMAKE_ENVIRONMENT_PATH]
			   [NO_CMAKE_PATH]
			   [NO_SYSTEM_ENVIRONMENT_PATH]
			   [NO_CMAKE_SYSTEM_PATH]
			   [CMAKE_FIND_ROOT_PATH_BOTH |
			    ONLY_CMAKE_FIND_ROOT_PATH |
			    NO_CMAKE_FIND_ROOT_PATH]
			  )

	      This  command  is used to find a library. A cache entry named by
	      <VAR> is created to store the result of this  command.   If  the
	      library  is  found  the result is stored in the variable and the
	      search will not be repeated unless the variable is cleared.   If
	      nothing  is  found,  the	result will be <VAR>-NOTFOUND, and the
	      search will be attempted again the  next	time  find_library  is
	      invoked with the same variable.  The name of the library that is
	      searched for is specified by the names listed  after  the	 NAMES
	      argument.	   Additional  search locations can be specified after
	      the PATHS argument.  If ENV var is found in the HINTS  or	 PATHS
	      section  the environment variable var will be read and converted
	      from a system environment variable to  a	cmake  style  list  of
	      paths.   For  example ENV PATH would be a way to list the system
	      path variable. The argument after DOC will be used for the docu‐
	      mentation	 string	 in  the cache.	 PATH_SUFFIXES specifies addi‐
	      tional subdirectories to check below each search path.

	      If NO_DEFAULT_PATH is specified, then no	additional  paths  are
	      added  to	 the  search. If NO_DEFAULT_PATH is not specified, the
	      search process is as follows:

	      1. Search paths specified	 in  cmake-specific  cache  variables.
	      These  are  intended  to	be  used  on  the  command line with a
	      -DVAR=value.  This can be skipped if NO_CMAKE_PATH is passed.

		 <prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
		 <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
		 CMAKE_LIBRARY_PATH
		 CMAKE_FRAMEWORK_PATH

	      2. Search paths specified in  cmake-specific  environment	 vari‐
	      ables.  These are intended to be set in the user's shell config‐
	      uration.	This can be skipped  if	 NO_CMAKE_ENVIRONMENT_PATH  is
	      passed.

		 <prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
		 <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
		 CMAKE_LIBRARY_PATH
		 CMAKE_FRAMEWORK_PATH

	      3. Search the paths specified by the HINTS option.  These should
	      be paths computed by system introspection, such as a  hint  pro‐
	      vided by the location of another item already found.  Hard-coded
	      guesses should be specified with the PATHS option.

	      4. Search the standard system environment variables. This can be
	      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

		 PATH
		 LIB

	      5.  Search cmake variables defined in the Platform files for the
	      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH  is
	      passed.

		 <prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
		 <prefix>/lib for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
		 CMAKE_SYSTEM_LIBRARY_PATH
		 CMAKE_SYSTEM_FRAMEWORK_PATH

	      6.  Search  the  paths  specified	 by the PATHS option or in the
	      short-hand  version  of  the  command.   These   are   typically
	      hard-coded guesses.

	      On Darwin or systems supporting OS X Frameworks, the cmake vari‐
	      able    CMAKE_FIND_FRAMEWORK can be set to empty or one  of  the
	      following:

		 "FIRST"  - Try to find frameworks before standard
			    libraries or headers. This is the default on Darwin.
		 "LAST"	  - Try to find frameworks after standard
			    libraries or headers.
		 "ONLY"	  - Only try to find frameworks.
		 "NEVER" - Never try to find frameworks.

	      On  Darwin  or  systems supporting OS X Application Bundles, the
	      cmake variable CMAKE_FIND_APPBUNDLE can be set to empty  or  one
	      of the following:

		 "FIRST"  - Try to find application bundles before standard
			    programs. This is the default on Darwin.
		 "LAST"	  - Try to find application bundles after standard
			    programs.
		 "ONLY"	  - Only try to find application bundles.
		 "NEVER" - Never try to find application bundles.

	      The  CMake  variable  CMAKE_FIND_ROOT_PATH specifies one or more
	      directories to be prepended to  all  other  search  directories.
	      This  effectively "re-roots" the entire search under given loca‐
	      tions. By default it is empty.  It  is  especially  useful  when
	      cross-compiling  to  point  to  the root directory of the target
	      environment and CMake will search there too. By default at first
	      the  directories	listed	in  CMAKE_FIND_ROOT_PATH  and then the
	      non-rooted directories will be searched.	The  default  behavior
	      can  be  adjusted	 by setting CMAKE_FIND_ROOT_PATH_MODE_LIBRARY.
	      This behavior can be manually overridden on a per-call basis. By
	      using  CMAKE_FIND_ROOT_PATH_BOTH	the  search  order  will be as
	      described	 above.	 If  NO_CMAKE_FIND_ROOT_PATH  is   used	  then
	      CMAKE_FIND_ROOT_PATH	will	  not	   be	  used.	    If
	      ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted direc‐
	      tories will be searched.

	      The  default  search  order  is  designed to be most-specific to
	      least-specific for common use cases.  Projects may override  the
	      order by simply calling the command multiple times and using the
	      NO_* options:

		 find_library(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
		 find_library(<VAR> NAMES name)

	      Once one of the calls succeeds the result variable will  be  set
	      and stored in the cache so that no call will search again.

	      When  more than one value is given to the NAMES option this com‐
	      mand by default will consider one name  at  a  time  and	search
	      every  directory	for  it.   The NAMES_PER_DIR option tells this
	      command to consider one directory at a time and search  for  all
	      names in it.

	      If the library found is a framework, then VAR will be set to the
	      full path to the framework <fullPath>/A.framework. When  a  full
	      path  to	a  framework  is  used	as a library, CMake will use a
	      -framework A, and a -F<fullPath> to link the  framework  to  the
	      target.

	      If  the  global property FIND_LIBRARY_USE_LIB64_PATHS is set all
	      search paths will be tested as normal, with "64/" appended,  and
	      with all matches of "lib/" replaced with "lib64/". This property
	      is automatically set for the platforms that are known to need it
	      if  at  least one of the languages supported by the PROJECT com‐
	      mand is enabled.

       find_package
	      Load settings for an external project.

		find_package(<package> [version] [EXACT] [QUIET] [MODULE]
			     [REQUIRED] [[COMPONENTS] [components...]]
			     [OPTIONAL_COMPONENTS components...]
			     [NO_POLICY_SCOPE])

	      Finds and loads  settings	 from  an  external  project.	<pack‐
	      age>_FOUND  will	be  set	 to  indicate  whether the package was
	      found.  When the package is found	 package-specific  information
	      is provided through variables and imported targets documented by
	      the package itself.  The QUIET option disables messages  if  the
	      package  cannot be found.	 The MODULE option disables the second
	      signature documented below.  The REQUIRED option stops  process‐
	      ing with an error message if the package cannot be found.

	      A	 package-specific  list	 of  required components may be listed
	      after the COMPONENTS option (or after  the  REQUIRED  option  if
	      present).	  Additional  optional	components may be listed after
	      OPTIONAL_COMPONENTS.  Available components and  their  influence
	      on  whether  a  package is considered to be found are defined by
	      the target package.

	      The [version] argument requests a version with which the package
	      found	  should       be      compatible      (format	    is
	      major[.minor[.patch[.tweak]]]).  The EXACT option requests  that
	      the  version  be matched exactly.	 If no [version] and/or compo‐
	      nent list is given to a recursive invocation inside a  find-mod‐
	      ule,  the	 corresponding	arguments  are forwarded automatically
	      from the outer call (including the EXACT	flag  for  [version]).
	      Version support is currently provided only on a package-by-pack‐
	      age basis (details below).

	      User code should generally look for  packages  using  the	 above
	      simple  signature.   The remainder of this command documentation
	      specifies the full command signature and details of  the	search
	      process.	Project maintainers wishing to provide a package to be
	      found by this command are encouraged to read on.

	      The command has two modes by which  it  searches	for  packages:
	      "Module"	mode and "Config" mode.	 Module mode is available when
	      the command is invoked with the above reduced signature.	 CMake
	      searches	 for   a  file	called	"Find<package>.cmake"  in  the
	      CMAKE_MODULE_PATH followed by the CMake  installation.   If  the
	      file is found, it is read and processed by CMake.	 It is respon‐
	      sible for finding the package, checking the version, and produc‐
	      ing  any	needed messages.  Many find-modules provide limited or
	      no support for versioning; check the module  documentation.   If
	      no  module  is found and the MODULE option is not given the com‐
	      mand proceeds to Config mode.

	      The complete Config mode command signature is:

		find_package(<package> [version] [EXACT] [QUIET]
			     [REQUIRED] [[COMPONENTS] [components...]]
			     [CONFIG|NO_MODULE]
			     [NO_POLICY_SCOPE]
			     [NAMES name1 [name2 ...]]
			     [CONFIGS config1 [config2 ...]]
			     [HINTS path1 [path2 ... ]]
			     [PATHS path1 [path2 ... ]]
			     [PATH_SUFFIXES suffix1 [suffix2 ...]]
			     [NO_DEFAULT_PATH]
			     [NO_CMAKE_ENVIRONMENT_PATH]
			     [NO_CMAKE_PATH]
			     [NO_SYSTEM_ENVIRONMENT_PATH]
			     [NO_CMAKE_PACKAGE_REGISTRY]
			     [NO_CMAKE_BUILDS_PATH]
			     [NO_CMAKE_SYSTEM_PATH]
			     [NO_CMAKE_SYSTEM_PACKAGE_REGISTRY]
			     [CMAKE_FIND_ROOT_PATH_BOTH |
			      ONLY_CMAKE_FIND_ROOT_PATH |
			      NO_CMAKE_FIND_ROOT_PATH])

	      The CONFIG option may be used to skip Module mode explicitly and
	      switch  to  Config  mode.	  It is synonymous to using NO_MODULE.
	      Config mode is also implied by use of options not	 specified  in
	      the reduced signature.

	      Config  mode attempts to locate a configuration file provided by
	      the package to be found.	A cache entry called <package>_DIR  is
	      created  to  hold the directory containing the file.  By default
	      the command searches for a package with the name <package>.   If
	      the  NAMES  option  is  given  the  names	 following it are used
	      instead of <package>.  The command searches for  a  file	called
	      "<name>Config.cmake"   or	 "<lower-case-name>-config.cmake"  for
	      each name specified.  A replacement set of  possible  configura‐
	      tion  file  names	 may  be  given using the CONFIGS option.  The
	      search procedure is specified below.  Once found, the configura‐
	      tion  file  is  read  and processed by CMake.  Since the file is
	      provided by the package it already knows the location of package
	      contents.	  The full path to the configuration file is stored in
	      the cmake variable <package>_CONFIG.

	      All configuration files which  have  been	 considered  by	 CMake
	      while  searching	for  an	 installation  of  the package with an
	      appropriate version are stored  in  the  cmake  variable	<pack‐
	      age>_CONSIDERED_CONFIGS,	 the  associated  versions  in	<pack‐
	      age>_CONSIDERED_VERSIONS.

	      If the package configuration file cannot	be  found  CMake  will
	      generate	an error describing the problem unless the QUIET argu‐
	      ment is specified.  If REQUIRED is specified and the package  is
	      not  found  a  fatal  error  is generated and the configure step
	      stops executing.	If <package>_DIR has been set to  a  directory
	      not  containing  a  configuration	 file CMake will ignore it and
	      search from scratch.

	      When the [version] argument is given Config mode will only  find
	      a	 version  of  the  package  that claims compatibility with the
	      requested version (format is major[.minor[.patch[.tweak]]]).  If
	      the EXACT option is given only a version of the package claiming
	      an exact match of the requested version  may  be	found.	 CMake
	      does  not	 establish  any	 convention for the meaning of version
	      numbers.	Package version numbers are checked by "version" files
	      provided	by  the	 packages themselves.  For a candidate package
	      configuration file "<config-file>.cmake" the corresponding  ver‐
	      sion  file  is  located  next  to	 it  and  named	 either "<con‐
	      fig-file>-version.cmake" or "<config-file>Version.cmake".	 If no
	      such  version  file  is available then the configuration file is
	      assumed to not be compatible  with  any  requested  version.   A
	      basic  version file containing generic version matching code can
	      be created using the  macro  write_basic_package_version_file(),
	      see  its documentation for more details.	When a version file is
	      found it is loaded to check the requested version	 number.   The
	      version  file is loaded in a nested scope in which the following
	      variables have been defined:

		PACKAGE_FIND_NAME	   = the <package> name
		PACKAGE_FIND_VERSION	   = full requested version string
		PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0
		PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0
		PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0
		PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0
		PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4

	      The version file checks whether it satisfies the requested  ver‐
	      sion and sets these variables:

		PACKAGE_VERSION		   = full provided version string
		PACKAGE_VERSION_EXACT	   = true if version is exact match
		PACKAGE_VERSION_COMPATIBLE = true if version is compatible
		PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version

	      These  variables	are  checked  by  the  find_package command to
	      determine whether the configuration file provides an  acceptable
	      version.	 They  are  not	 available after the find_package call
	      returns.	If the version is acceptable the  following  variables
	      are set:

		<package>_VERSION	= full provided version string
		<package>_VERSION_MAJOR = major version if provided, else 0
		<package>_VERSION_MINOR = minor version if provided, else 0
		<package>_VERSION_PATCH = patch version if provided, else 0
		<package>_VERSION_TWEAK = tweak version if provided, else 0
		<package>_VERSION_COUNT = number of version components, 0 to 4

	      and  the	corresponding  package	configuration  file is loaded.
	      When multiple package configuration files	 are  available	 whose
	      version  files claim compatibility with the version requested it
	      is unspecified which one is  chosen.   No	 attempt  is  made  to
	      choose a highest or closest version number.

	      Config  mode  provides  an elaborate interface and search proce‐
	      dure.  Much of the interface is provided	for  completeness  and
	      for  use internally by find-modules loaded by Module mode.  Most
	      user code should simply call

		find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])

	      in order to find a package.  Package maintainers providing CMake
	      package  configuration  files are encouraged to name and install
	      them such that the procedure outlined below will find them with‐
	      out requiring use of additional options.

	      CMake constructs a set of possible installation prefixes for the
	      package.	Under each prefix several directories are searched for
	      a	 configuration	file.	The  tables below show the directories
	      searched.	 Each entry is meant for installation trees  following
	      Windows (W), UNIX (U), or Apple (A) conventions.

		<prefix>/						(W)
		<prefix>/(cmake|CMake)/					(W)
		<prefix>/<name>*/					(W)
		<prefix>/<name>*/(cmake|CMake)/				(W)
		<prefix>/(lib/<arch>|lib|share)/cmake/<name>*/		(U)
		<prefix>/(lib/<arch>|lib|share)/<name>*/		(U)
		<prefix>/(lib/<arch>|lib|share)/<name>*/(cmake|CMake)/	(U)

	      On  systems  supporting  OS X Frameworks and Application Bundles
	      the following directories are searched for frameworks or bundles
	      containing a configuration file:

		<prefix>/<name>.framework/Resources/			(A)
		<prefix>/<name>.framework/Resources/CMake/		(A)
		<prefix>/<name>.framework/Versions/*/Resources/		(A)
		<prefix>/<name>.framework/Versions/*/Resources/CMake/	(A)
		<prefix>/<name>.app/Contents/Resources/			(A)
		<prefix>/<name>.app/Contents/Resources/CMake/		(A)

	      In  all cases the <name> is treated as case-insensitive and cor‐
	      responds to any of the names specified (<package> or names given
	      by    NAMES).	Paths	with   lib/<arch>   are	  enabled   if
	      CMAKE_LIBRARY_ARCHITECTURE is set.  If PATH_SUFFIXES  is	speci‐
	      fied  the	 suffixes  are	appended  to each (W) or (U) directory
	      entry one-by-one.

	      This set of directories is intended to work in cooperation  with
	      projects	that provide configuration files in their installation
	      trees.  Directories above	 marked	 with  (W)  are	 intended  for
	      installations  on	 Windows where the prefix may point at the top
	      of an application's installation directory.  Those  marked  with
	      (U)  are	intended for installations on UNIX platforms where the
	      prefix is shared by multiple packages.  This is merely a conven‐
	      tion,  so	 all (W) and (U) directories are still searched on all
	      platforms.  Directories marked with (A) are intended for instal‐
	      lations	 on    Apple	platforms.     The   cmake   variables
	      CMAKE_FIND_FRAMEWORK  and	 CMAKE_FIND_APPBUNDLE  determine   the
	      order of preference as specified below.

	      The  set	of installation prefixes is constructed using the fol‐
	      lowing steps.  If NO_DEFAULT_PATH is specified all NO_*  options
	      are enabled.

	      1.  Search  paths	 specified  in cmake-specific cache variables.
	      These are intended to  be	 used  on  the	command	 line  with  a
	      -DVAR=value.  This can be skipped if NO_CMAKE_PATH is passed.

		 CMAKE_PREFIX_PATH
		 CMAKE_FRAMEWORK_PATH
		 CMAKE_APPBUNDLE_PATH

	      2.  Search  paths	 specified in cmake-specific environment vari‐
	      ables.  These are intended to be set in the user's shell config‐
	      uration.	 This  can  be skipped if NO_CMAKE_ENVIRONMENT_PATH is
	      passed.

		 <package>_DIR
		 CMAKE_PREFIX_PATH
		 CMAKE_FRAMEWORK_PATH
		 CMAKE_APPBUNDLE_PATH

	      3. Search paths specified by the HINTS option.  These should  be
	      paths  computed by system introspection, such as a hint provided
	      by the location  of  another  item  already  found.   Hard-coded
	      guesses should be specified with the PATHS option.

	      4. Search the standard system environment variables. This can be
	      skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed.	 Path  entries
	      ending in "/bin" or "/sbin" are automatically converted to their
	      parent directories.

		 PATH

	      5. Search project build trees recently  configured  in  a	 CMake
	      GUI.  This can be skipped if NO_CMAKE_BUILDS_PATH is passed.  It
	      is intended for the case when a user is building multiple depen‐
	      dent projects one after another.

	      6. Search paths stored in the CMake user package registry.  This
	      can be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed.  On  Win‐
	      dows a <package> may appear under registry key

		HKEY_CURRENT_USER\Software\Kitware\CMake\Packages\<package>

	      as  a  REG_SZ  value,  with  arbitrary  name, that specifies the
	      directory containing the package configuration  file.   On  UNIX
	      platforms a <package> may appear under the directory

		~/.cmake/packages/<package>

	      as  a  file,  with  arbitrary  name, whose content specifies the
	      directory containing the package configuration  file.   See  the
	      export(PACKAGE)  command to create user package registry entries
	      for project build trees.

	      7. Search cmake variables defined in the Platform files for  the
	      current  system.	This can be skipped if NO_CMAKE_SYSTEM_PATH is
	      passed.

		 CMAKE_SYSTEM_PREFIX_PATH
		 CMAKE_SYSTEM_FRAMEWORK_PATH
		 CMAKE_SYSTEM_APPBUNDLE_PATH

	      8. Search paths stored in the  CMake  system  package  registry.
	      This  can	 be  skipped  if  NO_CMAKE_SYSTEM_PACKAGE_REGISTRY  is
	      passed.  On Windows a <package> may appear under registry key

		HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package>

	      as a REG_SZ value,  with	arbitrary  name,  that	specifies  the
	      directory	 containing  the package configuration file.  There is
	      no system package registry on non-Windows platforms.

	      9. Search paths specified by the PATHS option.  These are	 typi‐
	      cally hard-coded guesses.

	      On Darwin or systems supporting OS X Frameworks, the cmake vari‐
	      able    CMAKE_FIND_FRAMEWORK can be set to empty or one  of  the
	      following:

		 "FIRST"  - Try to find frameworks before standard
			    libraries or headers. This is the default on Darwin.
		 "LAST"	  - Try to find frameworks after standard
			    libraries or headers.
		 "ONLY"	  - Only try to find frameworks.
		 "NEVER" - Never try to find frameworks.

	      On  Darwin  or  systems supporting OS X Application Bundles, the
	      cmake variable CMAKE_FIND_APPBUNDLE can be set to empty  or  one
	      of the following:

		 "FIRST"  - Try to find application bundles before standard
			    programs. This is the default on Darwin.
		 "LAST"	  - Try to find application bundles after standard
			    programs.
		 "ONLY"	  - Only try to find application bundles.
		 "NEVER" - Never try to find application bundles.

	      The  CMake  variable  CMAKE_FIND_ROOT_PATH specifies one or more
	      directories to be prepended to  all  other  search  directories.
	      This  effectively "re-roots" the entire search under given loca‐
	      tions. By default it is empty.  It  is  especially  useful  when
	      cross-compiling  to  point  to  the root directory of the target
	      environment and CMake will search there too. By default at first
	      the  directories	listed	in  CMAKE_FIND_ROOT_PATH  and then the
	      non-rooted directories will be searched.	The  default  behavior
	      can  be  adjusted	 by setting CMAKE_FIND_ROOT_PATH_MODE_PACKAGE.
	      This behavior can be manually overridden on a per-call basis. By
	      using  CMAKE_FIND_ROOT_PATH_BOTH	the  search  order  will be as
	      described	 above.	 If  NO_CMAKE_FIND_ROOT_PATH  is   used	  then
	      CMAKE_FIND_ROOT_PATH	will	  not	   be	  used.	    If
	      ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted direc‐
	      tories will be searched.

	      The  default  search  order  is  designed to be most-specific to
	      least-specific for common use cases.  Projects may override  the
	      order by simply calling the command multiple times and using the
	      NO_* options:

		 find_package(<package> PATHS paths... NO_DEFAULT_PATH)
		 find_package(<package>)

	      Once one of the calls succeeds the result variable will  be  set
	      and stored in the cache so that no call will search again.

	      Every  non-REQUIRED  find_package() call can be disabled by set‐
	      ting the variable CMAKE_DISABLE_FIND_PACKAGE_<package> to	 TRUE.
	      See  the documentation for the CMAKE_DISABLE_FIND_PACKAGE_<pack‐
	      age> variable for more information.

	      When  loading  a	find  module  or  package  configuration  file
	      find_package  defines variables to provide information about the
	      call arguments (and restores their original state before return‐
	      ing):

	       <package>_FIND_REQUIRED	    = true if REQUIRED option was given
	       <package>_FIND_QUIETLY	    = true if QUIET option was given
	       <package>_FIND_VERSION	    = full requested version string
	       <package>_FIND_VERSION_MAJOR = major version if requested, else 0
	       <package>_FIND_VERSION_MINOR = minor version if requested, else 0
	       <package>_FIND_VERSION_PATCH = patch version if requested, else 0
	       <package>_FIND_VERSION_TWEAK = tweak version if requested, else 0
	       <package>_FIND_VERSION_COUNT = number of version components, 0 to 4
	       <package>_FIND_VERSION_EXACT = true if EXACT option was given
	       <package>_FIND_COMPONENTS    = list of requested components
	       <package>_FIND_REQUIRED_<c>  = true if component <c> is required
					      false if component <c> is optional

	      In  Module  mode	the loaded find module is responsible to honor
	      the request detailed by these variables; see the find module for
	      details.	 In  Config mode find_package handles REQUIRED, QUIET,
	      and version options automatically but leaves it to  the  package
	      configuration  file  to  handle  components  in a way that makes
	      sense for the package.  The package configuration file  may  set
	      <package>_FOUND  to  false  to  tell find_package that component
	      requirements are not satisfied.

	      See the cmake_policy() command documentation for	discussion  of
	      the NO_POLICY_SCOPE option.

       find_path
	      Find the directory containing a file.

		 find_path(<VAR> name1 [path1 path2 ...])

	      This  is the short-hand signature for the command that is suffi‐
	      cient in many cases.  It is the same  as	find_path(<VAR>	 name1
	      [PATHS path1 path2 ...])

		 find_path(
			   <VAR>
			   name | NAMES name1 [name2 ...]
			   [HINTS path1 [path2 ... ENV var]]
			   [PATHS path1 [path2 ... ENV var]]
			   [PATH_SUFFIXES suffix1 [suffix2 ...]]
			   [DOC "cache documentation string"]
			   [NO_DEFAULT_PATH]
			   [NO_CMAKE_ENVIRONMENT_PATH]
			   [NO_CMAKE_PATH]
			   [NO_SYSTEM_ENVIRONMENT_PATH]
			   [NO_CMAKE_SYSTEM_PATH]
			   [CMAKE_FIND_ROOT_PATH_BOTH |
			    ONLY_CMAKE_FIND_ROOT_PATH |
			    NO_CMAKE_FIND_ROOT_PATH]
			  )

	      This  command  is	 used to find a directory containing the named
	      file. A cache entry named by  <VAR>  is  created	to  store  the
	      result of this command.  If the file in a directory is found the
	      result is stored in the variable and  the	 search	 will  not  be
	      repeated	unless	the variable is cleared.  If nothing is found,
	      the result will  be  <VAR>-NOTFOUND,  and	 the  search  will  be
	      attempted again the next time find_path is invoked with the same
	      variable.	 The name of the file in a directory that is  searched
	      for  is  specified by the names listed after the NAMES argument.
	      Additional search locations can be  specified  after  the	 PATHS
	      argument.	 If ENV var is found in the HINTS or PATHS section the
	      environment variable var will be read and converted from a  sys‐
	      tem  environment	variable  to a cmake style list of paths.  For
	      example ENV PATH would be a way to list the  system  path	 vari‐
	      able.  The argument after DOC will be used for the documentation
	      string in the cache.  PATH_SUFFIXES specifies additional	subdi‐
	      rectories to check below each search path.

	      If  NO_DEFAULT_PATH  is  specified, then no additional paths are
	      added to the search. If NO_DEFAULT_PATH is  not  specified,  the
	      search process is as follows:

	      1.  Search  paths	 specified  in cmake-specific cache variables.
	      These are intended to  be	 used  on  the	command	 line  with  a
	      -DVAR=value.  This can be skipped if NO_CMAKE_PATH is passed.

		 <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
		 <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
		 CMAKE_INCLUDE_PATH
		 CMAKE_FRAMEWORK_PATH

	      2.  Search  paths	 specified in cmake-specific environment vari‐
	      ables.  These are intended to be set in the user's shell config‐
	      uration.	 This  can  be skipped if NO_CMAKE_ENVIRONMENT_PATH is
	      passed.

		 <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
		 <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
		 CMAKE_INCLUDE_PATH
		 CMAKE_FRAMEWORK_PATH

	      3. Search the paths specified by the HINTS option.  These should
	      be  paths	 computed by system introspection, such as a hint pro‐
	      vided by the location of another item already found.  Hard-coded
	      guesses should be specified with the PATHS option.

	      4. Search the standard system environment variables. This can be
	      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

		 PATH
		 INCLUDE

	      5. Search cmake variables defined in the Platform files for  the
	      current  system.	This can be skipped if NO_CMAKE_SYSTEM_PATH is
	      passed.

		 <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
		 <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
		 CMAKE_SYSTEM_INCLUDE_PATH
		 CMAKE_SYSTEM_FRAMEWORK_PATH

	      6. Search the paths specified by the  PATHS  option  or  in  the
	      short-hand   version   of	 the  command.	 These	are  typically
	      hard-coded guesses.

	      On Darwin or systems supporting OS X Frameworks, the cmake vari‐
	      able     CMAKE_FIND_FRAMEWORK  can be set to empty or one of the
	      following:

		 "FIRST"  - Try to find frameworks before standard
			    libraries or headers. This is the default on Darwin.
		 "LAST"	  - Try to find frameworks after standard
			    libraries or headers.
		 "ONLY"	  - Only try to find frameworks.
		 "NEVER" - Never try to find frameworks.

	      On Darwin or systems supporting OS X  Application	 Bundles,  the
	      cmake  variable  CMAKE_FIND_APPBUNDLE can be set to empty or one
	      of the following:

		 "FIRST"  - Try to find application bundles before standard
			    programs. This is the default on Darwin.
		 "LAST"	  - Try to find application bundles after standard
			    programs.
		 "ONLY"	  - Only try to find application bundles.
		 "NEVER" - Never try to find application bundles.

	      The CMake variable CMAKE_FIND_ROOT_PATH specifies	 one  or  more
	      directories  to  be  prepended  to all other search directories.
	      This effectively "re-roots" the entire search under given	 loca‐
	      tions.  By  default  it  is  empty. It is especially useful when
	      cross-compiling to point to the root  directory  of  the	target
	      environment and CMake will search there too. By default at first
	      the directories listed  in  CMAKE_FIND_ROOT_PATH	and  then  the
	      non-rooted  directories  will  be searched. The default behavior
	      can be adjusted  by  setting  CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.
	      This behavior can be manually overridden on a per-call basis. By
	      using CMAKE_FIND_ROOT_PATH_BOTH the  search  order  will	be  as
	      described	  above.   If  NO_CMAKE_FIND_ROOT_PATH	is  used  then
	      CMAKE_FIND_ROOT_PATH     will	not	 be	 used.	    If
	      ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted direc‐
	      tories will be searched.

	      The default search order is  designed  to	 be  most-specific  to
	      least-specific  for common use cases.  Projects may override the
	      order by simply calling the command multiple times and using the
	      NO_* options:

		 find_path(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
		 find_path(<VAR> NAMES name)

	      Once  one	 of the calls succeeds the result variable will be set
	      and stored in the cache so that no call will search again.

	      When searching for frameworks,  if  the  file  is	 specified  as
	      A/b.h, then the framework search will look for A.framework/Head‐
	      ers/b.h. If that is found the path will be set to	 the  path  to
	      the  framework. CMake will convert this to the correct -F option
	      to include the file.

       find_program
	      Find an executable program.

		 find_program(<VAR> name1 [path1 path2 ...])

	      This is the short-hand signature for the command that is	suffi‐
	      cient in many cases.  It is the same as find_program(<VAR> name1
	      [PATHS path1 path2 ...])

		 find_program(
			   <VAR>
			   name | NAMES name1 [name2 ...]
			   [HINTS path1 [path2 ... ENV var]]
			   [PATHS path1 [path2 ... ENV var]]
			   [PATH_SUFFIXES suffix1 [suffix2 ...]]
			   [DOC "cache documentation string"]
			   [NO_DEFAULT_PATH]
			   [NO_CMAKE_ENVIRONMENT_PATH]
			   [NO_CMAKE_PATH]
			   [NO_SYSTEM_ENVIRONMENT_PATH]
			   [NO_CMAKE_SYSTEM_PATH]
			   [CMAKE_FIND_ROOT_PATH_BOTH |
			    ONLY_CMAKE_FIND_ROOT_PATH |
			    NO_CMAKE_FIND_ROOT_PATH]
			  )

	      This command is used to find a program. A cache entry  named  by
	      <VAR>  is	 created  to store the result of this command.	If the
	      program is found the result is stored in the  variable  and  the
	      search  will not be repeated unless the variable is cleared.  If
	      nothing is found, the result will	 be  <VAR>-NOTFOUND,  and  the
	      search  will  be	attempted  again the next time find_program is
	      invoked with the same variable.  The name of the program that is
	      searched	for  is	 specified by the names listed after the NAMES
	      argument.	  Additional search locations can be  specified	 after
	      the  PATHS  argument.  If ENV var is found in the HINTS or PATHS
	      section the environment variable var will be read and  converted
	      from  a  system  environment  variable  to a cmake style list of
	      paths.  For example ENV PATH would be a way to list  the	system
	      path variable. The argument after DOC will be used for the docu‐
	      mentation string in the cache.   PATH_SUFFIXES  specifies	 addi‐
	      tional subdirectories to check below each search path.

	      If  NO_DEFAULT_PATH  is  specified, then no additional paths are
	      added to the search. If NO_DEFAULT_PATH is  not  specified,  the
	      search process is as follows:

	      1.  Search  paths	 specified  in cmake-specific cache variables.
	      These are intended to  be	 used  on  the	command	 line  with  a
	      -DVAR=value.  This can be skipped if NO_CMAKE_PATH is passed.

		 <prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
		 CMAKE_PROGRAM_PATH
		 CMAKE_APPBUNDLE_PATH

	      2.  Search  paths	 specified in cmake-specific environment vari‐
	      ables.  These are intended to be set in the user's shell config‐
	      uration.	 This  can  be skipped if NO_CMAKE_ENVIRONMENT_PATH is
	      passed.

		 <prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
		 CMAKE_PROGRAM_PATH
		 CMAKE_APPBUNDLE_PATH

	      3. Search the paths specified by the HINTS option.  These should
	      be  paths	 computed by system introspection, such as a hint pro‐
	      vided by the location of another item already found.  Hard-coded
	      guesses should be specified with the PATHS option.

	      4. Search the standard system environment variables. This can be
	      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

		 PATH

	      5. Search cmake variables defined in the Platform files for  the
	      current  system.	This can be skipped if NO_CMAKE_SYSTEM_PATH is
	      passed.

		 <prefix>/[s]bin for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
		 CMAKE_SYSTEM_PROGRAM_PATH
		 CMAKE_SYSTEM_APPBUNDLE_PATH

	      6. Search the paths specified by the  PATHS  option  or  in  the
	      short-hand   version   of	 the  command.	 These	are  typically
	      hard-coded guesses.

	      On Darwin or systems supporting OS X Frameworks, the cmake vari‐
	      able     CMAKE_FIND_FRAMEWORK  can be set to empty or one of the
	      following:

		 "FIRST"  - Try to find frameworks before standard
			    libraries or headers. This is the default on Darwin.
		 "LAST"	  - Try to find frameworks after standard
			    libraries or headers.
		 "ONLY"	  - Only try to find frameworks.
		 "NEVER" - Never try to find frameworks.

	      On Darwin or systems supporting OS X  Application	 Bundles,  the
	      cmake  variable  CMAKE_FIND_APPBUNDLE can be set to empty or one
	      of the following:

		 "FIRST"  - Try to find application bundles before standard
			    programs. This is the default on Darwin.
		 "LAST"	  - Try to find application bundles after standard
			    programs.
		 "ONLY"	  - Only try to find application bundles.
		 "NEVER" - Never try to find application bundles.

	      The CMake variable CMAKE_FIND_ROOT_PATH specifies	 one  or  more
	      directories  to  be  prepended  to all other search directories.
	      This effectively "re-roots" the entire search under given	 loca‐
	      tions.  By  default  it  is  empty. It is especially useful when
	      cross-compiling to point to the root  directory  of  the	target
	      environment and CMake will search there too. By default at first
	      the directories listed  in  CMAKE_FIND_ROOT_PATH	and  then  the
	      non-rooted  directories  will  be searched. The default behavior
	      can be adjusted  by  setting  CMAKE_FIND_ROOT_PATH_MODE_PROGRAM.
	      This behavior can be manually overridden on a per-call basis. By
	      using CMAKE_FIND_ROOT_PATH_BOTH the  search  order  will	be  as
	      described	  above.   If  NO_CMAKE_FIND_ROOT_PATH	is  used  then
	      CMAKE_FIND_ROOT_PATH     will	not	 be	 used.	    If
	      ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted direc‐
	      tories will be searched.

	      The default search order is  designed  to	 be  most-specific  to
	      least-specific  for common use cases.  Projects may override the
	      order by simply calling the command multiple times and using the
	      NO_* options:

		 find_program(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
		 find_program(<VAR> NAMES name)

	      Once  one	 of the calls succeeds the result variable will be set
	      and stored in the cache so that no call will search again.

       fltk_wrap_ui
	      Create FLTK user interfaces Wrappers.

		fltk_wrap_ui(resultingLibraryName source1
			     source2 ... sourceN )

	      Produce .h and .cxx files for all the .fl and .fld files listed.
	      The  resulting  .h  and  .cxx  files will be added to a variable
	      named resultingLibraryName_FLTK_UI_SRCS which should be added to
	      your library.

       foreach
	      Evaluate a group of commands for each value in a list.

		foreach(loop_var arg1 arg2 ...)
		  COMMAND1(ARGS ...)
		  COMMAND2(ARGS ...)
		  ...
		endforeach(loop_var)

	      All  commands  between  foreach  and the matching endforeach are
	      recorded without being invoked.  Once the endforeach  is	evalu‐
	      ated,  the  recorded  list  of commands is invoked once for each
	      argument listed in the original foreach  command.	  Before  each
	      iteration	 of  the  loop "${loop_var}" will be set as a variable
	      with the current value in the list.

		foreach(loop_var RANGE total)
		foreach(loop_var RANGE start stop [step])

	      Foreach can also iterate over  a	generated  range  of  numbers.
	      There are three types of this iteration:

	      *	 When specifying single number, the range will have elements 0
	      to "total".

	      * When specifying two numbers, the range will have elements from
	      the first number to the second number.

	      *	 The  third  optional  number is the increment used to iterate
	      from the first number to the second number.

		foreach(loop_var IN [LISTS [list1 [...]]]
				    [ITEMS [item1 [...]]])

	      Iterates over a precise list of items.  The LISTS	 option	 names
	      list-valued  variables to be traversed, including empty elements
	      (an empty string is a zero-length list).	The ITEMS option  ends
	      argument	parsing and includes all arguments following it in the
	      iteration.

       function
	      Start recording a function for later invocation as a command.

		function(<name> [arg1 [arg2 [arg3 ...]]])
		  COMMAND1(ARGS ...)
		  COMMAND2(ARGS ...)
		  ...
		endfunction(<name>)

	      Define a function named <name> that takes arguments  named  arg1
	      arg2 arg3 (...).	Commands listed after function, but before the
	      matching endfunction, are not  invoked  until  the  function  is
	      invoked.	When it is invoked, the commands recorded in the func‐
	      tion are first modified by replacing formal parameters (${arg1})
	      with  the arguments passed, and then invoked as normal commands.
	      In addition to referencing the formal parameters you can	refer‐
	      ence  the variable ARGC which will be set to the number of argu‐
	      ments passed into the function as well as ARGV0 ARGV1 ARGV2  ...
	      which  will  have	 the actual values of the arguments passed in.
	      This facilitates creating	 functions  with  optional  arguments.
	      Additionally  ARGV  holds the list of all arguments given to the
	      function and ARGN holds the list	of  arguments  past  the  last
	      expected argument.

	      A	 function  opens  a  new  scope: see set(var PARENT_SCOPE) for
	      details.

	      See the cmake_policy() command documentation for the behavior of
	      policies inside functions.

       get_cmake_property
	      Get a property of the CMake instance.

		get_cmake_property(VAR property)

	      Get  a property from the CMake instance.	The value of the prop‐
	      erty is stored in the variable VAR.   If	the  property  is  not
	      found, VAR will be set to "NOTFOUND".  Some supported properties
	      include: VARIABLES, CACHE_VARIABLES, COMMANDS, MACROS, and  COM‐
	      PONENTS.

	      See also the more general get_property() command.

       get_directory_property
	      Get a property of DIRECTORY scope.

		get_directory_property(<variable> [DIRECTORY <dir>] <prop-name>)

	      Store  a	property of directory scope in the named variable.  If
	      the property is not defined the empty-string is  returned.   The
	      DIRECTORY	 argument  specifies  another  directory from which to
	      retrieve the property value.  The specified directory must  have
	      already been traversed by CMake.

		get_directory_property(<variable> [DIRECTORY <dir>]
				       DEFINITION <var-name>)

	      Get a variable definition from a directory.  This form is useful
	      to get a variable definition from another directory.

	      See also the more general get_property() command.

       get_filename_component
	      Get a specific component of a full filename.

		get_filename_component(<VAR> <FileName> <COMP> [CACHE])

	      Set <VAR> to a component of <FileName>, where <COMP> is one of:

	       DIRECTORY = Directory without file name
	       NAME	 = File name without directory
	       EXT	 = File name longest extension (.b.c from d/a.b.c)
	       NAME_WE	 = File name without directory or longest extension
	       ABSOLUTE	 = Full path to file
	       REALPATH	 = Full path to existing file with symlinks resolved
	       PATH	 = Legacy alias for DIRECTORY (use for CMake <= 2.8.11)

	      Paths are returned with forward slashes  and  have  no  trailing
	      slahes.  The longest file extension is always considered. If the
	      optional CACHE argument is specified,  the  result  variable  is
	      added to the cache.

		get_filename_component(<VAR> FileName
				       PROGRAM [PROGRAM_ARGS <ARG_VAR>]
				       [CACHE])

	      The  program in FileName will be found in the system search path
	      or left as a full path.  If PROGRAM_ARGS is  present  with  PRO‐
	      GRAM,  then  any	command-line arguments present in the FileName
	      string are split from the program name and stored in  <ARG_VAR>.
	      This  is used to separate a program name from its arguments in a

       get_property
	      Get a property.

		get_property(<variable>
			     <GLOBAL		 |
			      DIRECTORY [dir]	 |
			      TARGET	<target> |
			      SOURCE	<source> |
			      TEST	<test>	 |
			      CACHE	<entry>	 |
			      VARIABLE>
			     PROPERTY <name>
			     [SET | DEFINED | BRIEF_DOCS | FULL_DOCS])

	      Get one property from one object in a scope.  The first argument
	      specifies the variable in which to store the result.  The second
	      argument determines the scope from which to  get	the  property.
	      It must be one of the following:

	      GLOBAL scope is unique and does not accept a name.

	      DIRECTORY	 scope	defaults  to the current directory but another
	      directory (already processed by CMake) may be named by  full  or
	      relative path.

	      TARGET scope must name one existing target.

	      SOURCE scope must name one source file.

	      TEST scope must name one existing test.

	      CACHE scope must name one cache entry.

	      VARIABLE scope is unique and does not accept a name.

	      The required PROPERTY option is immediately followed by the name
	      of the property to get.  If the property is  not	set  an	 empty
	      value  is	 returned.  If the SET option is given the variable is
	      set to a boolean value indicating whether the property has  been
	      set.   If	 the  DEFINED option is given the variable is set to a
	      boolean value indicating whether the property has	 been  defined
	      such  as	with  define_property.	If  BRIEF_DOCS or FULL_DOCS is
	      given then the variable is set to a string containing documenta‐
	      tion  for the requested property.	 If documentation is requested
	      for a property that has not been defined NOTFOUND is returned.

       get_source_file_property
	      Get a property for a source file.

		get_source_file_property(VAR file property)

	      Get a property from a source file.  The value of the property is
	      stored  in  the variable VAR.  If the property is not found, VAR
	      will be set to "NOTFOUND".  Use  set_source_files_properties  to
	      set property values.  Source file properties usually control how
	      the file is built. One property that is always there is LOCATION

	      See also the more general get_property() command.

       get_target_property
	      Get a property from a target.

		get_target_property(VAR target property)

	      Get a property from a target.   The value	 of  the  property  is
	      stored  in  the variable VAR.  If the property is not found, VAR
	      will be set to "NOTFOUND".   Use	set_target_properties  to  set
	      property	values.	  Properties are usually used to control how a
	      target is built, but some query the target instead.   This  com‐
	      mand  can get properties for any target so far created. The tar‐
	      gets do not need to be in the current CMakeLists.txt file.

	      See also the more general get_property() command.

       get_test_property
	      Get a property of the test.

		get_test_property(test property VAR)

	      Get a property from the Test.  The  value	 of  the  property  is
	      stored  in  the variable VAR.  If the property is not found, VAR
	      will be set to "NOTFOUND". For a list of standard properties you
	      can type cmake --help-property-list

	      See also the more general get_property() command.

       if     Conditionally execute a group of commands.

		if(expression)
		  # then section.
		  COMMAND1(ARGS ...)
		  COMMAND2(ARGS ...)
		  ...
		elseif(expression2)
		  # elseif section.
		  COMMAND1(ARGS ...)
		  COMMAND2(ARGS ...)
		  ...
		else(expression)
		  # else section.
		  COMMAND1(ARGS ...)
		  COMMAND2(ARGS ...)
		  ...
		endif(expression)

	      Evaluates the given expression.  If the result is true, the com‐
	      mands in the THEN section are invoked.  Otherwise, the  commands
	      in  the  else section are invoked.  The elseif and else sections
	      are optional. You may have multiple elseif  clauses.  Note  that
	      the  expression  in  the else and endif clause is optional. Long
	      expressions can be used and there	 is  a	traditional  order  of
	      precedence.  Parenthetical  expressions are evaluated first fol‐
	      lowed by unary operators such as EXISTS, COMMAND,	 and  DEFINED.
	      Then  any	 EQUAL,	 LESS, GREATER, STRLESS, STRGREATER, STREQUAL,
	      MATCHES will be evaluated. Then NOT operators and	 finally  AND,
	      OR operators will be evaluated. Possible expressions are:

		if(<constant>)

	      True  if the constant is 1, ON, YES, TRUE, Y, or a non-zero num‐
	      ber.  False if the constant is 0, OFF,  NO,  FALSE,  N,  IGNORE,
	      NOTFOUND,	 '', or ends in the suffix '-NOTFOUND'.	 Named boolean
	      constants are case-insensitive.  If the argument is not  one  of
	      these constants, it is treated as a variable:

		if(<variable>)

	      True  if	the variable is defined to a value that is not a false
	      constant.	 False otherwise.  (Note macro arguments are not vari‐
	      ables.)

		if(NOT <expression>)

	      True if the expression is not true.

		if(<expr1> AND <expr2>)

	      True if both expressions would be considered true individually.

		if(<expr1> OR <expr2>)

	      True if either expression would be considered true individually.

		if(COMMAND command-name)

	      True  if the given name is a command, macro or function that can
	      be invoked.

		if(POLICY policy-id)

	      True if the given name  is  an  existing	policy	(of  the  form
	      CMP<NNNN>).

		if(TARGET target-name)

	      True if the given name is an existing target, built or imported.

		if(EXISTS file-name)
		if(EXISTS directory-name)

	      True  if	the  named  file  or  directory	 exists.   Behavior is
	      well-defined only for full paths.

		if(file1 IS_NEWER_THAN file2)

	      True if file1 is newer than file2 or if one  of  the  two	 files
	      doesn't  exist. Behavior is well-defined only for full paths. If
	      the file time stamps are exactly the same, an IS_NEWER_THAN com‐
	      parison  returns	true,  so  that any dependent build operations
	      will occur in the event of a tie.	 This  includes	 the  case  of
	      passing the same file name for both file1 and file2.

		if(IS_DIRECTORY directory-name)

	      True if the given name is a directory.  Behavior is well-defined
	      only for full paths.

		if(IS_SYMLINK file-name)

	      True if  the  given  name	 is  a	symbolic  link.	  Behavior  is
	      well-defined only for full paths.

		if(IS_ABSOLUTE path)

	      True if the given path is an absolute path.

		if(<variable|string> MATCHES regex)

	      True  if	the given string or variable's value matches the given
	      regular expression.

		if(<variable|string> LESS <variable|string>)
		if(<variable|string> GREATER <variable|string>)
		if(<variable|string> EQUAL <variable|string>)

	      True if the given string or variable's value is a	 valid	number
	      and the inequality or equality is true.

		if(<variable|string> STRLESS <variable|string>)
		if(<variable|string> STRGREATER <variable|string>)
		if(<variable|string> STREQUAL <variable|string>)

	      True  if	the  given string or variable's value is lexicographi‐
	      cally less (or greater, or equal) than the string or variable on
	      the right.

		if(<variable|string> VERSION_LESS <variable|string>)
		if(<variable|string> VERSION_EQUAL <variable|string>)
		if(<variable|string> VERSION_GREATER <variable|string>)

	      Component-wise integer version number comparison (version format
	      is major[.minor[.patch[.tweak]]]).

		if(DEFINED <variable>)

	      True if the given variable is defined. It does not matter if the
	      variable is true or false just if it has been set.

		if((expression) AND (expression OR (expression)))

	      The  expressions	inside the parenthesis are evaluated first and
	      then the remaining expression is evaluated as  in	 the  previous
	      examples.	 Where	there are nested parenthesis the innermost are
	      evaluated as part of evaluating  the  expression	that  contains
	      them.

	      The  if  command was written very early in CMake's history, pre‐
	      dating the ${} variable evaluation syntax, and  for  convenience
	      evaluates variables named by its arguments as shown in the above
	      signatures.  Note	 that  normal  variable	 evaluation  with  ${}
	      applies  before  the  if	command	 even  receives the arguments.
	      Therefore code like

		set(var1 OFF)
		set(var2 "var1")
		if(${var2})

	      appears to the if command as

		if(var1)

	      and is evaluated according to the if(<variable>) case documented
	      above.  The result is OFF which is false.	 However, if we remove
	      the ${} from the example then the command sees

		if(var2)

	      which is true because var2 is defined to "var1" which is	not  a
	      false constant.

	      Automatic	 evaluation  applies  in  the other cases whenever the
	      above-documented signature accepts <variable|string>:

	      1) The left hand argument to MATCHES is first checked to see  if
	      it  is  a	 defined variable, if so the variable's value is used,
	      otherwise the original value is used.

	      2) If the left hand argument to MATCHES is  missing  it  returns
	      false without error

	      3)  Both left and right hand arguments to LESS GREATER EQUAL are
	      independently tested to see if they are defined variables, if so
	      their  defined  values  are used otherwise the original value is
	      used.

	      4) Both left and right hand arguments to STRLESS	STREQUAL  STR‐
	      GREATER  are  independently  tested  to  see if they are defined
	      variables, if so their defined values  are  used	otherwise  the
	      original value is used.

	      5)  Both	left  and  right  hand argumemnts to VERSION_LESS VER‐
	      SION_EQUAL VERSION_GREATER are independently tested  to  see  if
	      they  are defined variables, if so their defined values are used
	      otherwise the original value is used.

	      6) The right hand argument to NOT is tested to see if  it	 is  a
	      boolean  constant,  if  so  the  value  is used, otherwise it is
	      assumed to be a variable and it is dereferenced.

	      7) The left and right hand arguments to AND OR are independently
	      tested to see if they are boolean constants, if so they are used
	      as such, otherwise they are assumed  to  be  variables  and  are
	      dereferenced.

       include
	      Load and run CMake code from a file or module.

		include(<file|module> [OPTIONAL] [RESULT_VARIABLE <VAR>]
				      [NO_POLICY_SCOPE])

	      Load and run CMake code from the file given.  Variable reads and
	      writes access the scope of the  caller  (dynamic	scoping).   If
	      OPTIONAL	is  present,  then no error is raised if the file does
	      not exist.  If RESULT_VARIABLE is given the variable will be set
	      to  the  full filename which has been included or NOTFOUND if it
	      failed.

	      If a module is specified instead of a file, the file  with  name
	      <modulename>.cmake  is searched first in CMAKE_MODULE_PATH, then
	      in the CMake module directory. There is one exception  to	 this:
	      if the file which calls include() is located itself in the CMake
	      module directory, then  first  the  CMake	 module	 directory  is
	      searched	and  CMAKE_MODULE_PATH	afterwards.  See  also	policy
	      CMP0017.

	      See the cmake_policy() command documentation for	discussion  of
	      the NO_POLICY_SCOPE option.

       include_directories
	      Add include directories to the build.

		include_directories([AFTER|BEFORE] [SYSTEM] dir1 dir2 ...)

	      Add  the	given directories to those the compiler uses to search
	      for include files.  Relative paths are interpreted  as  relative
	      to the current source directory.

	      The  include  directories	 are  added  to the directory property
	      INCLUDE_DIRECTORIES for the current CMakeLists  file.  They  are
	      also  added  to the target property INCLUDE_DIRECTORIES for each
	      target in the current CMakeLists file. The target property  val‐
	      ues are the ones used by the generators.

	      By default the directories are appended onto the current list of
	      directories. This default behavior can  be  changed  by  setting
	      CMAKE_INCLUDE_DIRECTORIES_BEFORE to ON. By using AFTER or BEFORE
	      explicitly, you can select  between  appending  and  prepending,
	      independent of the default.

	      If  the  SYSTEM  option  is given, the compiler will be told the
	      directories are meant as	system	include	 directories  on  some
	      platforms (signalling this setting might achieve effects such as
	      the compiler skipping warnings, or  these	 fixed-install	system
	      files not being considered in dependency calculations - see com‐
	      piler docs).

       include_external_msproject
	      Include an external Microsoft project file in a workspace.

		include_external_msproject(projectname location
					   [TYPE projectTypeGUID]
					   [GUID projectGUID]
					   [PLATFORM platformName]
					   dep1 dep2 ...)

	      Includes	an  external  Microsoft	 project  in   the   generated
	      workspace	 file.	Currently does nothing on UNIX. This will cre‐
	      ate a target named [projectname].	  This	can  be	 used  in  the
	      add_dependencies	command	 to make things depend on the external
	      project.

	      TYPE, GUID and PLATFORM are optional parameters that  allow  one
	      to specify the type of project, id (GUID) of the project and the
	      name of the  target  platform.   This  is	 useful	 for  projects
	      requiring	 values	 other	than  the default (e.g. WIX projects).
	      These options are not supported by the Visual Studio  6  genera‐
	      tor.

       include_regular_expression
	      Set the regular expression used for dependency checking.

		include_regular_expression(regex_match [regex_complain])

	      Set  the	regular expressions used in dependency checking.  Only
	      files matching regex_match will be traced as dependencies.  Only
	      files  matching  regex_complain  will  generate warnings if they
	      cannot be found (standard header paths are not  searched).   The
	      defaults are:

		regex_match    = "^.*$" (match everything)
		regex_complain = "^$" (match empty string only)

       install
	      Specify rules to run at install time.

	      This  command generates installation rules for a project.	 Rules
	      specified by calls to this command within a source directory are
	      executed	in order during installation.  The order across direc‐
	      tories is not defined.

	      There are multiple signatures for this command.	Some  of  them
	      define  installation  properties for files and targets.  Proper‐
	      ties common to multiple signatures are covered here but they are
	      valid only for signatures that specify them.

	      DESTINATION  arguments  specify the directory on disk to which a
	      file will be installed.  If a full path (with a leading slash or
	      drive  letter) is given it is used directly.  If a relative path
	      is  given	 it  is	 interpreted  relative	 to   the   value   of
	      CMAKE_INSTALL_PREFIX.  The  prefix  can  be relocated at install
	      time using DESTDIR mechanism explained in the CMAKE_INSTALL_PRE‐
	      FIX variable documentation.

	      PERMISSIONS  arguments  specify permissions for installed files.
	      Valid permissions are  OWNER_READ,  OWNER_WRITE,	OWNER_EXECUTE,
	      GROUP_READ, GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE,
	      WORLD_EXECUTE, SETUID, and SETGID.  Permissions that do not make
	      sense on certain platforms are ignored on those platforms.

	      The CONFIGURATIONS argument specifies a list of build configura‐
	      tions for which the install rule applies (Debug, Release, etc.).

	      The COMPONENT argument specifies an installation component  name
	      with  which the install rule is associated, such as "runtime" or
	      "development".   During  component-specific  installation	  only
	      install  rules  associated with the given component name will be
	      executed.	  During  a  full  installation	 all  components   are
	      installed.  If  COMPONENT	 is  not  provided a default component
	      "Unspecified" is created. The default component name may be con‐
	      trolled with the CMAKE_INSTALL_DEFAULT_COMPONENT_NAME variable.

	      The  RENAME argument specifies a name for an installed file that
	      may be different from the original file.	 Renaming  is  allowed
	      only when a single file is installed by the command.

	      The  OPTIONAL  argument specifies that it is not an error if the
	      file to be installed does not exist.

	      The TARGETS signature:

		install(TARGETS targets... [EXPORT <export-name>]
			[[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|
			  PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]
			 [DESTINATION <dir>]
			 [INCLUDES DESTINATION [<dir> ...]]
			 [PERMISSIONS permissions...]
			 [CONFIGURATIONS [Debug|Release|...]]
			 [COMPONENT <component>]
			 [OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
			] [...])

	      The TARGETS form specifies rules for installing targets  from  a
	      project.	 There	are  five  kinds  of  target files that may be
	      installed: ARCHIVE, LIBRARY,  RUNTIME,  FRAMEWORK,  and  BUNDLE.
	      Executables  are	treated	 as RUNTIME targets, except that those
	      marked with the MACOSX_BUNDLE property  are  treated  as	BUNDLE
	      targets  on OS X. Static libraries are always treated as ARCHIVE
	      targets. Module libraries are always treated as LIBRARY targets.
	      For  non-DLL  platforms  shared libraries are treated as LIBRARY
	      targets, except that those marked with  the  FRAMEWORK  property
	      are treated as FRAMEWORK targets on OS X.	 For DLL platforms the
	      DLL part of a shared library is treated as a RUNTIME target  and
	      the  corresponding  import library is treated as an ARCHIVE tar‐
	      get. All Windows-based systems including Cygwin  are  DLL	 plat‐
	      forms.  The  ARCHIVE,  LIBRARY, RUNTIME, and FRAMEWORK arguments
	      change the type of target to  which  the	subsequent  properties
	      apply.   If  none	 is given the installation properties apply to
	      all target types.	 If only one is given  then  only  targets  of
	      that type will be installed (which can be used to install just a
	      DLL or just an import library).The INCLUDES  DESTINATION	speci‐
	      fies  a  list  of	 directories which will be added to the INTER‐
	      FACE_INCLUDE_DIRECTORIES	of  the	 <targets>  when  exported  by
	      install(EXPORT).	If a relative path is specified, it is treated
	      as relative to the $<INSTALL_PREFIX>.

	      The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments	 cause
	      subsequent  properties  to  be applied to installing a FRAMEWORK
	      shared library target's associated files on non-Apple platforms.
	      Rules  defined by these arguments are ignored on Apple platforms
	      because the associated files are installed into the  appropriate
	      locations inside the framework folder.  See documentation of the
	      PRIVATE_HEADER, PUBLIC_HEADER, and  RESOURCE  target  properties
	      for details.

	      Either  NAMELINK_ONLY  or	 NAMELINK_SKIP	may  be specified as a
	      LIBRARY option.  On some platforms a  versioned  shared  library
	      has a symbolic link such as

		lib<name>.so -> lib<name>.so.1

	      where   "lib<name>.so.1"	is  the	 soname	 of  the  library  and
	      "lib<name>.so" is a "namelink"  allowing	linkers	 to  find  the
	      library  when given "-l<name>".  The NAMELINK_ONLY option causes
	      installation of only the	namelink  when	a  library  target  is
	      installed.   The	NAMELINK_SKIP  option  causes  installation of
	      library files other than the namelink when a library  target  is
	      installed.   When	 neither  option  is  given  both portions are
	      installed.  On platforms where versioned shared libraries do not
	      have   namelinks	 or  when  a  library  is  not	versioned  the
	      NAMELINK_SKIP option installs the library and the	 NAMELINK_ONLY
	      option  installs	nothing.  See the VERSION and SOVERSION target
	      properties for details on creating versioned shared libraries.

	      One or more groups of properties may be specified	 in  a	single
	      call  to	the  TARGETS  form  of	this command.  A target may be
	      installed more than once to different locations.	Consider hypo‐
	      thetical targets "myExe", "mySharedLib", and "myStaticLib".  The
	      code

		  install(TARGETS myExe mySharedLib myStaticLib
			  RUNTIME DESTINATION bin
			  LIBRARY DESTINATION lib
			  ARCHIVE DESTINATION lib/static)
		  install(TARGETS mySharedLib DESTINATION /some/full/path)

	      will install myExe to  <prefix>/bin  and	myStaticLib  to	 <pre‐
	      fix>/lib/static.	 On  non-DLL  platforms	 mySharedLib  will  be
	      installed to <prefix>/lib and /some/full/path.  On DLL platforms
	      the  mySharedLib	DLL  will  be  installed  to  <prefix>/bin and
	      /some/full/path and its import  library  will  be	 installed  to
	      <prefix>/lib/static and /some/full/path.

	      The  EXPORT option associates the installed target files with an
	      export called <export-name>.  It must appear before any RUNTIME,
	      LIBRARY,	or  ARCHIVE  options.	To actually install the export
	      file itself, call install(EXPORT).   See	documentation  of  the
	      install(EXPORT ...) signature below for details.

	      Installing  a target with EXCLUDE_FROM_ALL set to true has unde‐
	      fined behavior.

	      The FILES signature:

		install(FILES files... DESTINATION <dir>
			[PERMISSIONS permissions...]
			[CONFIGURATIONS [Debug|Release|...]]
			[COMPONENT <component>]
			[RENAME <name>] [OPTIONAL])

	      The FILES form  specifies	 rules	for  installing	 files	for  a
	      project.	 File  names  given  as relative paths are interpreted
	      with respect to the current source directory.   Files  installed
	      by  this	form  are  by  default	given permissions OWNER_WRITE,
	      OWNER_READ, GROUP_READ, and WORLD_READ if no  PERMISSIONS	 argu‐
	      ment is given.

	      The PROGRAMS signature:

		install(PROGRAMS files... DESTINATION <dir>
			[PERMISSIONS permissions...]
			[CONFIGURATIONS [Debug|Release|...]]
			[COMPONENT <component>]
			[RENAME <name>] [OPTIONAL])

	      The PROGRAMS form is identical to the FILES form except that the
	      default  permissions  for	 the  installed	 file	also   include
	      OWNER_EXECUTE,  GROUP_EXECUTE,  and WORLD_EXECUTE.  This form is
	      intended to install programs that are not targets, such as shell
	      scripts.	 Use  the TARGETS form to install targets built within
	      the project.

	      The DIRECTORY signature:

		install(DIRECTORY dirs... DESTINATION <dir>
			[FILE_PERMISSIONS permissions...]
			[DIRECTORY_PERMISSIONS permissions...]
			[USE_SOURCE_PERMISSIONS] [OPTIONAL]
			[CONFIGURATIONS [Debug|Release|...]]
			[COMPONENT <component>] [FILES_MATCHING]
			[[PATTERN <pattern> | REGEX <regex>]
			 [EXCLUDE] [PERMISSIONS permissions...]] [...])

	      The DIRECTORY form installs contents of one or more  directories
	      to  a given destination.	The directory structure is copied ver‐
	      batim to the destination.	 The last component of each  directory
	      name  is	appended  to  the destination directory but a trailing
	      slash may be used to avoid this because it leaves the last  com‐
	      ponent  empty.   Directory  names	 given	as  relative paths are
	      interpreted with respect to the current source directory.	 If no
	      input  directory	names are given the destination directory will
	      be created but nothing will be installed into it.	 The FILE_PER‐
	      MISSIONS	and  DIRECTORY_PERMISSIONS options specify permissions
	      given  to	 files	and  directories  in  the   destination.    If
	      USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not,
	      file permissions will be copied from the source directory struc‐
	      ture.   If  no permissions are specified files will be given the
	      default permissions specified in the FILES form of the  command,
	      and the directories will be given the default permissions speci‐
	      fied in the PROGRAMS form of the command.

	      Installation of directories may be controlled with  fine	granu‐
	      larity  using  the  PATTERN  or  REGEX  options.	 These "match"
	      options specify a globbing  pattern  or  regular	expression  to
	      match directories or files encountered within input directories.
	      They may be used to apply certain options (see below) to a  sub‐
	      set  of the files and directories encountered.  The full path to
	      each input file or directory (with forward slashes)  is  matched
	      against the expression.  A PATTERN will match only complete file
	      names: the portion of the full path matching  the	 pattern  must
	      occur at the end of the file name and be preceded by a slash.  A
	      REGEX will match any portion of the full path but it may use '/'
	      and  '$' to simulate the PATTERN behavior.  By default all files
	      and directories are installed whether or not they	 are  matched.
	      The  FILES_MATCHING  option  may be given before the first match
	      option to disable installation of files  (but  not  directories)
	      not matched by any expression.  For example, the code

		install(DIRECTORY src/ DESTINATION include/myproj
			FILES_MATCHING PATTERN "*.h")

	      will extract and install header files from a source tree.

	      Some  options  may  follow a PATTERN or REGEX expression and are
	      applied only to files or directories matching them.  The EXCLUDE
	      option will skip the matched file or directory.  The PERMISSIONS
	      option overrides the permissions setting for the matched file or
	      directory.  For example the code

		install(DIRECTORY icons scripts/ DESTINATION share/myproj
			PATTERN "CVS" EXCLUDE
			PATTERN "scripts/*"
			PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ
				    GROUP_EXECUTE GROUP_READ)

	      will  install  the icons directory to share/myproj/icons and the
	      scripts directory to share/myproj.  The icons will  get  default
	      file  permissions,  the  scripts	will be given specific permis‐
	      sions, and any CVS directories will be excluded.

	      The SCRIPT and CODE signature:

		install([[SCRIPT <file>] [CODE <code>]] [...])

	      The SCRIPT form will invoke the given CMake script files	during
	      installation.   If  the  script  file name is a relative path it
	      will be interpreted with respect to the  current	source	direc‐
	      tory.   The  CODE	 form  will invoke the given CMake code during
	      installation.  Code is specified as a single argument  inside  a
	      double-quoted string. For example, the code

		install(CODE "MESSAGE(\"Sample install message.\")")

	      will print a message during installation.

	      The EXPORT signature:

		install(EXPORT <export-name> DESTINATION <dir>
			[NAMESPACE <namespace>] [FILE <name>.cmake]
			[PERMISSIONS permissions...]
			[CONFIGURATIONS [Debug|Release|...]]
			[EXPORT_LINK_INTERFACE_LIBRARIES]
			[COMPONENT <component>])

	      The  EXPORT  form generates and installs a CMake file containing
	      code to import targets from the installation tree	 into  another
	      project.	 Target	 installations	are associated with the export
	      <export-name> using the EXPORT  option  of  the  install(TARGETS
	      ...)  signature  documented  above.   The	 NAMESPACE option will
	      prepend <namespace> to the target names as they are  written  to
	      the  import  file.  By default the generated file will be called
	      <export-name>.cmake but the FILE option may be used to specify a
	      different	 name.	 The  value given to the FILE option must be a
	      file name with the  ".cmake"  extension.	 If  a	CONFIGURATIONS
	      option is given then the file will only be installed when one of
	      the named configurations is installed.  Additionally, the gener‐
	      ated import file will reference only the matching target config‐
	      urations.	  The  EXPORT_LINK_INTERFACE_LIBRARIES	 keyword,   if
	      present,	 causes	  the  contents	 of  the  properties  matching
	      (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)? to be exported,
	      when  policy CMP0022 is NEW.  If a COMPONENT option is specified
	      that does not match that given to the  targets  associated  with
	      <export-name> the behavior is undefined.	If a library target is
	      included in the export but a target to which  it	links  is  not
	      included the behavior is unspecified.

	      The  EXPORT  form is useful to help outside projects use targets
	      built and installed by the current project.   For	 example,  the
	      code

		install(TARGETS myexe EXPORT myproj DESTINATION bin)
		install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)

	      will  install  the  executable myexe to <prefix>/bin and code to
	      import it in the	file  "<prefix>/lib/myproj/myproj.cmake".   An
	      outside  project may load this file with the include command and
	      reference the myexe executable from the installation tree	 using
	      the imported target name mp_myexe as if the target were built in
	      its own tree.

	      NOTE: This command supercedes the	 INSTALL_TARGETS  command  and
	      the      target	   properties	   PRE_INSTALL_SCRIPT	   and
	      POST_INSTALL_SCRIPT.  It also replaces the FILES	forms  of  the
	      INSTALL_FILES  and  INSTALL_PROGRAMS  commands.	The processing
	      order of these install rules  relative  to  those	 generated  by
	      INSTALL_TARGETS, INSTALL_FILES, and INSTALL_PROGRAMS commands is
	      not defined.

       link_directories
	      Specify directories in which the linker will look for libraries.

		link_directories(directory1 directory2 ...)

	      Specify  the  paths  in  which  the  linker  should  search  for
	      libraries.  The command will apply only to targets created after
	      it is called. Relative paths given to this  command  are	inter‐
	      preted as relative to the current source directory, see CMP0015.

	      Note  that  this command is rarely necessary.  Library locations
	      returned	by  find_package()  and	 find_library()	 are  absolute
	      paths.   Pass  these absolute library file paths directly to the
	      target_link_libraries() command.	CMake will ensure  the	linker
	      finds them.

       list   List operations.

		list(LENGTH <list> <output variable>)
		list(GET <list> <element index> [<element index> ...]
		     <output variable>)
		list(APPEND <list> <element> [<element> ...])
		list(FIND <list> <value> <output variable>)
		list(INSERT <list> <element_index> <element> [<element> ...])
		list(REMOVE_ITEM <list> <value> [<value> ...])
		list(REMOVE_AT <list> <index> [<index> ...])
		list(REMOVE_DUPLICATES <list>)
		list(REVERSE <list>)
		list(SORT <list>)

	      LENGTH will return a given list's length.

	      GET  will	 return list of elements specified by indices from the
	      list.

	      APPEND will append elements to the list.

	      FIND will return the index of the element specified in the  list
	      or -1 if it wasn't found.

	      INSERT  will  insert elements to the list to the specified loca‐
	      tion.

	      REMOVE_AT and REMOVE_ITEM will remove items from the  list.  The
	      difference  is  that  REMOVE_ITEM	 will  remove the given items,
	      while REMOVE_AT will remove the items at the given indices.

	      REMOVE_DUPLICATES will remove duplicated items in the list.

	      REVERSE reverses the contents of the list in-place.

	      SORT sorts the list in-place alphabetically.

	      The list subcommands  APPEND,  INSERT,  REMOVE_AT,  REMOVE_ITEM,
	      REMOVE_DUPLICATES,  REVERSE  and	SORT may create new values for
	      the list within the current CMake variable scope. Similar to the
	      SET command, the LIST command creates new variable values in the
	      current scope, even if the list itself is actually defined in  a
	      parent  scope.  To  propagate  the  results  of these operations
	      upwards, use SET with PARENT_SCOPE, SET with CACHE INTERNAL,  or
	      some other means of value propagation.

	      NOTES:  A	 list  in  cmake is a ; separated group of strings. To
	      create a list the set command can be used. For example,  set(var
	      a	 b c d e)  creates a list with a;b;c;d;e, and set(var "a b c d
	      e") creates a string or a list with one item in it.

	      When specifying  index  values,  if  <element  index>  is	 0  or
	      greater,	it  is	indexed from the beginning of the list, with 0
	      representing the first list element. If <element index> is -1 or
	      lesser,  it  is indexed from the end of the list, with -1 repre‐
	      senting the last list element. Be	 careful  when	counting  with
	      negative	indices: they do not start from 0. -0 is equivalent to
	      0, the first list element.

       load_cache
	      Load in the values from another project's CMake cache.

		load_cache(pathToCacheFile READ_WITH_PREFIX
			   prefix entry1...)

	      Read the cache and store the requested entries in variables with
	      their  name prefixed with the given prefix.  This only reads the
	      values, and does not  create  entries  in	 the  local  project's
	      cache.

		load_cache(pathToCacheFile [EXCLUDE entry1...]
			   [INCLUDE_INTERNALS entry1...])

	      Load  in	the  values  from  another cache and store them in the
	      local project's cache as internal entries.  This is useful for a
	      project  that  depends  on  another project built in a different
	      tree.  EXCLUDE option can be used to provide a list  of  entries
	      to be excluded.  INCLUDE_INTERNALS can be used to provide a list
	      of internal entries  to  be  included.   Normally,  no  internal
	      entries  are  brought  in.   Use	of this form of the command is
	      strongly discouraged, but it is provided for  backward  compati‐
	      bility.

       load_command
	      Load a command into a running CMake.

		load_command(COMMAND_NAME <loc1> [loc2 ...])

	      The  given  locations  are  searched for a library whose name is
	      cmCOMMAND_NAME.  If found, it is loaded as a module and the com‐
	      mand  is added to the set of available CMake commands.  Usually,
	      TRY_COMPILE is used before this command to compile  the  module.
	      If the command is successfully loaded a variable named

		CMAKE_LOADED_COMMAND_<COMMAND_NAME>

	      will  be	set  to	 the  full path of the module that was loaded.
	      Otherwise the variable will not be set.

       macro  Start recording a macro for later invocation as a command.

		macro(<name> [arg1 [arg2 [arg3 ...]]])
		  COMMAND1(ARGS ...)
		  COMMAND2(ARGS ...)
		  ...
		endmacro(<name>)

	      Define a macro named <name> that takes arguments named arg1 arg2
	      arg3  (...).  Commands listed after macro, but before the match‐
	      ing endmacro, are not invoked until the macro is invoked.	  When
	      it is invoked, the commands recorded in the macro are first mod‐
	      ified by replacing formal parameters (${arg1})  with  the	 argu‐
	      ments  passed,  and then invoked as normal commands. In addition
	      to referencing the formal parameters you can reference the  val‐
	      ues  ${ARGC} which will be set to the number of arguments passed
	      into the function as well	 as  ${ARGV0}  ${ARGV1}	 ${ARGV2}  ...
	      which  will  have	 the actual values of the arguments passed in.
	      This facilitates creating macros with optional arguments.	 Addi‐
	      tionally	${ARGV}	 holds	the list of all arguments given to the
	      macro and ${ARGN} holds the list	of  arguments  past  the  last
	      expected	argument. Note that the parameters to a macro and val‐
	      ues such as ARGN are not variables in  the  usual	 CMake	sense.
	      They  are string replacements much like the C preprocessor would
	      do with a macro. If you want true CMake variables and/or	better
	      CMake scope control you should look at the function command.

	      See the cmake_policy() command documentation for the behavior of
	      policies inside macros.

       mark_as_advanced
	      Mark cmake cached variables as advanced.

		mark_as_advanced([CLEAR|FORCE] VAR VAR2 VAR...)

	      Mark the named cached variables as advanced.  An advanced	 vari‐
	      able  will  not be displayed in any of the cmake GUIs unless the
	      show advanced option is on.  If  CLEAR  is  the  first  argument
	      advanced	variables are changed back to unadvanced.  If FORCE is
	      the first argument, then the variable is made advanced.  If nei‐
	      ther  FORCE nor CLEAR is specified, new values will be marked as
	      advanced,	  but	 if    the    variable	  already    has    an
	      advanced/non-advanced state, it will not be changed.

	      It does nothing in script mode.

       math   Mathematical expressions.

		math(EXPR <output variable> <math expression>)

	      EXPR evaluates mathematical expression and returns result in the
	      output variable. Example mathematical expression is '5 * ( 10  +
	      13  )'.	Supported operators are + - * / % | & ^ ~ << >> * / %.
	      They have the same meaning  as they do in C code.

       message
	      Display a message to the user.

		message([STATUS|WARNING|AUTHOR_WARNING|FATAL_ERROR|SEND_ERROR]
			"message to display" ...)

	      The optional keyword determines the type of message:

		(none)	       = Important information
		STATUS	       = Incidental information
		WARNING	       = CMake Warning, continue processing
		AUTHOR_WARNING = CMake Warning (dev), continue processing
		SEND_ERROR     = CMake Error, continue processing,
					      but skip generation
		FATAL_ERROR    = CMake Error, stop processing and generation

	      The CMake command-line tool displays STATUS messages  on	stdout
	      and  all	other message types on stderr.	The CMake GUI displays
	      all messages in its log area.  The interactive  dialogs  (ccmake
	      and  CMakeSetup)	show STATUS messages one at a time on a status
	      line and other messages in interactive pop-up boxes.

	      CMake Warning and Error message text  displays  using  a	simple
	      markup language.	Non-indented text is formatted in line-wrapped
	      paragraphs delimited by newlines.	 Indented text	is  considered
	      pre-formatted.

       option Provides an option that the user can optionally select.

		option(<option_variable> "help string describing option"
		       [initial value])

	      Provide  an  option  for the user to select as ON or OFF.	 If no
	      initial value is provided, OFF is used.

	      If you have options that depend on the values of other  options,
	      see the module help for CMakeDependentOption.

       project
	      Set a name for the entire project.

		project(<projectname> [languageName1 languageName2 ... ] )

	      Sets  the name of the project.  Additionally this sets the vari‐
	      ables <projectName>_BINARY_DIR and  <projectName>_SOURCE_DIR  to
	      the respective values.

	      Optionally  you  can  specify  which languages your project sup‐
	      ports.  Example languages are CXX (i.e. C++), C,	Fortran,  etc.
	      By default C and CXX are enabled.	 E.g. if you do not have a C++
	      compiler, you can disable the check for it by explicitly listing
	      the languages you want to support, e.g. C.  By using the special
	      language "NONE" all checks for any language can be disabled.  If
	      a	 variable  exists  called CMAKE_PROJECT_<projectName>_INCLUDE,
	      the file pointed to by that variable will	 be  included  as  the
	      last step of the project command.

	      The  top-level  CMakeLists.txt file for a project must contain a
	      literal, direct call  to	the  project()	command;  loading  one
	      through  the  include()  command	is not sufficient.  If no such
	      call exists CMake will  implicitly  add  one  to	the  top  that
	      enables the default languages (C and CXX).

       qt_wrap_cpp
	      Create Qt Wrappers.

		qt_wrap_cpp(resultingLibraryName DestName
			    SourceLists ...)

	      Produce	moc   files  for  all  the  .h	files  listed  in  the
	      SourceLists.  The moc files will be added to the	library	 using
	      the DestName source list.

       qt_wrap_ui
	      Create Qt user interfaces Wrappers.

		qt_wrap_ui(resultingLibraryName HeadersDestName
			   SourcesDestName SourceLists ...)

	      Produce  .h  and	.cxx files for all the .ui files listed in the
	      SourceLists.  The .h files will be added to  the	library	 using
	      the HeadersDestNamesource list.  The .cxx files will be added to
	      the library using the SourcesDestNamesource list.

       remove_definitions
	      Removes -D define flags added by add_definitions.

		remove_definitions(-DFOO -DBAR ...)

	      Removes flags (added by add_definitions) from the compiler  com‐
	      mand line for sources in the current directory and below.

       return Return from a file, directory or function.

		return()

	      Returns from a file, directory or function. When this command is
	      encountered in an included file  (via  include()	or  find_pack‐
	      age()),  it  causes  processing  of the current file to stop and
	      control is returned to the including file. If it is  encountered
	      in  a  file which is not included by another file, e.g. a CMake‐
	      Lists.txt, control is returned to the parent directory if	 there
	      is  one.	If return is called in a function, control is returned
	      to the caller of the function. Note that a macro is not a	 func‐
	      tion and does not handle return like a function does.

       separate_arguments
	      Parse space-separated arguments into a semicolon-separated list.

		separate_arguments(<var> <UNIX|WINDOWS>_COMMAND "<args>")

	      Parses a unix- or windows-style command-line string "<args>" and
	      stores a semicolon-separated list of  the	 arguments  in	<var>.
	      The entire command line must be given in one "<args>" argument.

	      The  UNIX_COMMAND	 mode  separates  arguments by unquoted white‐
	      space.  It recognizes both single-quote and double-quote	pairs.
	      A	 backslash escapes the next literal character (\" is "); there
	      are no special escapes (\n is just n).

	      The WINDOWS_COMMAND mode parses a windows command-line using the
	      same  syntax  the	 runtime  library  uses	 to  construct argv at
	      startup.	It separates arguments by whitespace that is not  dou‐
	      ble-quoted.   Backslashes	 are  literal unless they precede dou‐
	      ble-quotes.  See the MSDN article "Parsing C Command-Line	 Argu‐
	      ments" for details.

		separate_arguments(VARIABLE)

	      Convert  the  value  of VARIABLE to a semi-colon separated list.
	      All spaces are replaced with ';'.	 This  helps  with  generating
	      command lines.

       set    Set a CMake, cache or environment variable to a given value.

		set(<variable> <value>
		    [[CACHE <type> <docstring> [FORCE]] | PARENT_SCOPE])

	      Within  CMake  sets <variable> to the value <value>.  <value> is
	      expanded before <variable> is set to it.	Normally, set will set
	      a	 regular  CMake variable. If CACHE is present, then the <vari‐
	      able> is put in the cache instead, unless it is already  in  the
	      cache.  See  section 'Variable types in CMake' below for details
	      of regular and cache variables and their interactions. If	 CACHE
	      is  used, <type> and <docstring> are required. <type> is used by
	      the CMake GUI to choose a widget with  which  the	 user  sets  a
	      value. The value for <type> may be one of

		FILEPATH = File chooser dialog.
		PATH	 = Directory chooser dialog.
		STRING	 = Arbitrary string.
		BOOL	 = Boolean ON/OFF checkbox.
		INTERNAL = No GUI entry (used for persistent variables).

	      If <type> is INTERNAL, the cache variable is marked as internal,
	      and will not be shown to the user in tools like cmake-gui.  This
	      is  intended  for	 values that should be persisted in the cache,
	      but which users should not  normally  change.  INTERNAL  implies
	      FORCE.

	      Normally, set(...CACHE...) creates cache variables, but does not
	      modify them. If FORCE is specified, the value of the cache vari‐
	      able  is set, even if the variable is already in the cache. This
	      should normally be avoided, as it will remove any changes to the
	      cache variable's value by the user.

	      If  PARENT_SCOPE	is  present,  the  variable will be set in the
	      scope above the current scope. Each new  directory  or  function
	      creates  a new scope. This command will set the value of a vari‐
	      able into the parent directory or calling function (whichever is
	      applicable to the case at hand). PARENT_SCOPE cannot be combined
	      with CACHE.

	      If <value> is not specified then the variable is removed instead
	      of set.  See also: the unset() command.

		set(<variable> <value1> ... <valueN>)

	      In  this case <variable> is set to a semicolon separated list of
	      values.

	      <variable> can be an environment variable such as:

		set( ENV{PATH} /home/martink )

	      in which case the environment variable will be set.

	      *** Variable types in CMake ***

	      In CMake there are two types of variables: normal variables  and
	      cache variables. Normal variables are meant for the internal use
	      of the script (just like	variables  in  most  programming  lan‐
	      guages);	they  are not persisted across CMake runs. Cache vari‐
	      ables (unless set with INTERNAL) are mostly intended for config‐
	      uration settings where the first CMake run determines a suitable
	      default value, which the user can then override, by editing  the
	      cache  with  tools  such as ccmake or cmake-gui. Cache variables
	      are stored in the CMake cache file,  and	are  persisted	across
	      CMake runs.

	      Both  types  can	exist  at the same time with the same name but
	      different values. When ${FOO} is evaluated,  CMake  first	 looks
	      for  a normal variable 'FOO' in scope and uses it if set. If and
	      only if no normal variable exists then  it  falls	 back  to  the
	      cache variable 'FOO'.

	      Some examples:

	      The  code 'set(FOO "x")' sets the normal variable 'FOO'. It does
	      not touch the cache, but it will hide any existing  cache	 value
	      'FOO'.

	      The code 'set(FOO "x" CACHE ...)' checks for 'FOO' in the cache,
	      ignoring any normal variable of the same name. If	 'FOO'	is  in
	      the  cache then nothing happens to either the normal variable or
	      the cache variable. If 'FOO' is not in the  cache,  then	it  is
	      added to the cache.

	      Finally,	whenever  a  cache  variable is added or modified by a
	      command, CMake also *removes* the normal variable	 of  the  same
	      name  from  the  current	scope so that an immediately following
	      evaluation of it will expose the newly cached value.

	      Normally projects should avoid using normal and cache  variables
	      of  the  same  name,  as this interaction can be hard to follow.
	      However, in some situations it can be useful. One example	 (used
	      by some projects):

	      A project has a subproject in its source tree. The child project
	      has its own CMakeLists.txt, which is included  from  the	parent
	      CMakeLists.txt  using add_subdirectory(). Now, if the parent and
	      the child project provide the same option (for  example  a  com‐
	      piler  option),  the  parent  gets  the  first  chance  to add a
	      user-editable option to the cache.  Normally,  the  child	 would
	      then use the same value that the parent uses. However, it may be
	      necessary to hard-code the value for the child project's	option
	      while still allowing the user to edit the value used by the par‐
	      ent project. The parent project can achieve this simply by  set‐
	      ting  a  normal  variable	 with the same name as the option in a
	      scope sufficient to hide the option's cache  variable  from  the
	      child completely. The parent has already set the cache variable,
	      so the child's set(...CACHE...) will do nothing, and  evaluating
	      the option variable will use the value from the normal variable,
	      which hides the cache variable.

       set_directory_properties
	      Set a property of the directory.

		set_directory_properties(PROPERTIES prop1 value1 prop2 value2)

	      Set a property for the current directory and subdirectories.  If
	      the property is not found, CMake will report an error. The prop‐
	      erties	include:    INCLUDE_DIRECTORIES,     LINK_DIRECTORIES,
	      INCLUDE_REGULAR_EXPRESSION,   and	  ADDITIONAL_MAKE_CLEAN_FILES.
	      ADDITIONAL_MAKE_CLEAN_FILES is a list  of	 files	that  will  be
	      cleaned as a part of "make clean" stage.

       set_property
	      Set a named property in a given scope.

		set_property(<GLOBAL				|
			      DIRECTORY [dir]			|
			      TARGET	[target1 [target2 ...]] |
			      SOURCE	[src1 [src2 ...]]	|
			      TEST	[test1 [test2 ...]]	|
			      CACHE	[entry1 [entry2 ...]]>
			     [APPEND] [APPEND_STRING]
			     PROPERTY <name> [value1 [value2 ...]])

	      Set  one property on zero or more objects of a scope.  The first
	      argument determines the scope in which the property is set.   It
	      must be one of the following:

	      GLOBAL scope is unique and does not accept a name.

	      DIRECTORY	 scope	defaults  to the current directory but another
	      directory (already processed by CMake) may be named by  full  or
	      relative path.

	      TARGET scope may name zero or more existing targets.

	      SOURCE  scope  may  name	zero  or more source files.  Note that
	      source file properties are visible only to targets added in  the
	      same directory (CMakeLists.txt).

	      TEST scope may name zero or more existing tests.

	      CACHE scope must name zero or more cache existing entries.

	      The required PROPERTY option is immediately followed by the name
	      of the property to set.  Remaining arguments are used to compose
	      the  property  value  in the form of a semicolon-separated list.
	      If the APPEND option is given the list is appended to any exist‐
	      ing  property  value.If  the  APPEND_STRING  option is given the
	      string is append to any existing property value as string,  i.e.
	      it results in a longer string and not a list of strings.

       set_source_files_properties
	      Source files can have properties that affect how they are built.

		set_source_files_properties([file1 [file2 [...]]]
					    PROPERTIES prop1 value1
					    [prop2 value2 [...]])

	      Set  properties  associated  with source files using a key/value
	      paired list.  See properties documentation for  those  known  to
	      CMake.   Unrecognized properties are ignored.  Source file prop‐
	      erties are visible only to targets added in the  same  directory
	      (CMakeLists.txt).

       set_target_properties
	      Targets can have properties that affect how they are built.

		set_target_properties(target1 target2 ...
				      PROPERTIES prop1 value1
				      prop2 value2 ...)

	      Set  properties  on  a  target. The syntax for the command is to
	      list all the files you want to change, and then provide the val‐
	      ues  you	want to set next.  You can use any prop value pair you
	      want and extract it later with the GET_TARGET_PROPERTY command.

	      Properties that affect the name of a target's output file are as
	      follows.	 The PREFIX and SUFFIX properties override the default
	      target name prefix (such as "lib") and suffix (such  as  ".so").
	      IMPORT_PREFIX  and  IMPORT_SUFFIX	 are the equivalent properties
	      for the import  library  corresponding  to  a  DLL  (for	SHARED
	      library  targets).   OUTPUT_NAME	sets the real name of a target
	      when it is built and can be used to help create two  targets  of
	      the  same	 name even though CMake requires unique logical target
	      names.  There is also a <CONFIG>_OUTPUT_NAME that	 can  set  the
	      output name on a per-configuration basis.	 <CONFIG>_POSTFIX sets
	      a postfix for the real name of the target when it is built under
	      the  configuration  named	 by  <CONFIG>  (in upper-case, such as
	      "DEBUG_POSTFIX").	 The value of  this  property  is  initialized
	      when  the	 target	 is  created  to  the  value  of  the variable
	      CMAKE_<CONFIG>_POSTFIX (except for  executable  targets  because
	      earlier  CMake versions which did not use this variable for exe‐
	      cutables).

	      The LINK_FLAGS property can be used to add extra	flags  to  the
	      link  step of a target. LINK_FLAGS_<CONFIG> will add to the con‐
	      figuration <CONFIG>, for example,	 DEBUG,	 RELEASE,  MINSIZEREL,
	      RELWITHDEBINFO.  DEFINE_SYMBOL sets the name of the preprocessor
	      symbol defined when compiling sources in a  shared  library.  If
	      not  set	here then it is set to target_EXPORTS by default (with
	      some substitutions if the target is not a valid  C  identifier).
	      This  is	useful	for  headers  to  know	whether they are being
	      included from inside their library or outside to properly	 setup
	      dllexport/dllimport decorations. The COMPILE_FLAGS property sets
	      additional compiler flags used to build sources within the  tar‐
	      get.   It may also be used to pass additional preprocessor defi‐
	      nitions.

	      The LINKER_LANGUAGE property is used to change the tool used  to
	      link  an	executable  or	shared library. The default is set the
	      language to match the files in the library. CXX and C are common
	      values for this property.

	      For  shared libraries VERSION and SOVERSION can be used to spec‐
	      ify the build version and API version respectively. When	build‐
	      ing  or installing appropriate symlinks are created if the plat‐
	      form supports symlinks and the linker supports so-names. If only
	      one of both is specified the missing is assumed to have the same
	      version number. For executables VERSION can be used  to  specify
	      the  build version. When building or installing appropriate sym‐
	      links are created if the platform supports symlinks. For	shared
	      libraries	 and  executables  on Windows the VERSION attribute is
	      parsed to extract a "major.minor" version number. These  numbers
	      are used as the image version of the binary.

	      There  are  a  few  properties  used  to	specify	 RPATH	rules.
	      INSTALL_RPATH is a semicolon-separated list specifying the rpath
	      to  use  in  installed  targets (for platforms that support it).
	      INSTALL_RPATH_USE_LINK_PATH is a boolean that  if	 set  to  true
	      will  append  directories	 in the linker search path and outside
	      the project to the INSTALL_RPATH. SKIP_BUILD_RPATH is a  boolean
	      specifying  whether  to  skip  automatic	generation of an rpath
	      allowing	 the   target	to   run   from	  the	build	 tree.
	      BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link
	      the target in the build tree with the INSTALL_RPATH.  This takes
	      precedence over SKIP_BUILD_RPATH and avoids the need for relink‐
	      ing before installation.	INSTALL_NAME_DIR is a string  specify‐
	      ing  the directory portion of the "install_name" field of shared
	      libraries on Mac OSX to use in the installed targets.  When  the
	      target	is    created	 the	values	  of   the   variables
	      CMAKE_INSTALL_RPATH,	    CMAKE_INSTALL_RPATH_USE_LINK_PATH,
	      CMAKE_SKIP_BUILD_RPATH,	 CMAKE_BUILD_WITH_INSTALL_RPATH,   and
	      CMAKE_INSTALL_NAME_DIR are used to initialize these properties.

	      PROJECT_LABEL can be used to change the name of the target in an
	      IDE  like	 visual	 studio.   VS_KEYWORD can be set to change the
	      visual studio keyword, for example Qt integration	 works	better
	      if this is set to Qt4VSv1.0.

	      VS_SCC_PROJECTNAME,    VS_SCC_LOCALPATH,	 VS_SCC_PROVIDER   and
	      VS_SCC_AUXPATH can be set to  add	 support  for  source  control
	      bindings in a  Visual Studio project file.

	      VS_GLOBAL_<variable>   can   be  set  to	add  a	Visual	Studio
	      project-specific global variable. Qt integration works better if
	      VS_GLOBAL_QtVersion  is  set  to	the  Qt	 version FindQt4.cmake
	      found. For example, "4.7.3"

	      The PRE_INSTALL_SCRIPT and  POST_INSTALL_SCRIPT  properties  are
	      the  old	way  to	 specify CMake scripts to run before and after
	      installing  a  target.   They  are  used	only  when   the   old
	      INSTALL_TARGETS  command is used to install the target.  Use the
	      INSTALL command instead.

	      The EXCLUDE_FROM_DEFAULT_BUILD property is used  by  the	visual
	      studio  generators.   If	it  is set to 1 the target will not be
	      part of the default build when you select "Build Solution". This
	      can   also   be	set   on   a   per-configuration  basis	 using
	      EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>.

       set_tests_properties
	      Set a property of the tests.

		set_tests_properties(test1 [test2...] PROPERTIES prop1 value1 prop2 value2)

	      Set a property for the tests. If	the  property  is  not	found,
	      CMake will report an error. The properties include:

	      WILL_FAIL:  If  set to true, this will invert the pass/fail flag
	      of the test.

	      PASS_REGULAR_EXPRESSION: If set, the test output will be checked
	      against  the  specified  regular expressions and at least one of
	      the regular expressions has to match, otherwise  the  test  will
	      fail.

		Example: PASS_REGULAR_EXPRESSION "TestPassed;All ok"

	      FAIL_REGULAR_EXPRESSION: If set, if the output will match to one
	      of specified regular expressions, the test will fail.

		Example: PASS_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"

	      Both PASS_REGULAR_EXPRESSION and FAIL_REGULAR_EXPRESSION	expect
	      a list of regular expressions.

	      TIMEOUT:	Setting this will limit the test runtime to the number
	      of seconds specified.

       site_name
	      Set the given variable to the name of the computer.

		site_name(variable)

       source_group
	      Define a grouping for sources in the makefile.

		source_group(name [REGULAR_EXPRESSION regex] [FILES src1 src2 ...])

	      Defines a group into which sources will  be  placed  in  project
	      files.  This is mainly used to setup file tabs in Visual Studio.
	      Any file whose name is listed or matches the regular  expression
	      will  be	placed	in  this  group.   If  a file matches multiple
	      groups, the LAST group that explicitly lists the	file  will  be
	      favored,	if  any.   If  no group explicitly lists the file, the
	      LAST group whose regular expression matches  the	file  will  be
	      favored.

	      The  name	 of  the group may contain backslashes to specify sub‐
	      groups:

		source_group(outer\\inner ...)

	      For backwards compatibility, this command also supports the for‐
	      mat:

		source_group(name regex)

       string String operations.

		string(REGEX MATCH <regular_expression>
		       <output variable> <input> [<input>...])
		string(REGEX MATCHALL <regular_expression>
		       <output variable> <input> [<input>...])
		string(REGEX REPLACE <regular_expression>
		       <replace_expression> <output variable>
		       <input> [<input>...])
		string(REPLACE <match_string>
		       <replace_string> <output variable>
		       <input> [<input>...])
		string(<MD5|SHA1|SHA224|SHA256|SHA384|SHA512>
		       <output variable> <input>)
		string(COMPARE EQUAL <string1> <string2> <output variable>)
		string(COMPARE NOTEQUAL <string1> <string2> <output variable>)
		string(COMPARE LESS <string1> <string2> <output variable>)
		string(COMPARE GREATER <string1> <string2> <output variable>)
		string(ASCII <number> [<number> ...] <output variable>)
		string(CONFIGURE <string1> <output variable>
		       [@ONLY] [ESCAPE_QUOTES])
		string(TOUPPER <string1> <output variable>)
		string(TOLOWER <string1> <output variable>)
		string(LENGTH <string> <output variable>)
		string(SUBSTRING <string> <begin> <length> <output variable>)
		string(STRIP <string> <output variable>)
		string(RANDOM [LENGTH <length>] [ALPHABET <alphabet>]
		       [RANDOM_SEED <seed>] <output variable>)
		string(FIND <string> <substring> <output variable> [REVERSE])
		string(TIMESTAMP <output variable> [<format string>] [UTC])
		string(MAKE_C_IDENTIFIER <input string> <output variable>)

	      REGEX MATCH will match the regular expression once and store the
	      match in the output variable.

	      REGEX MATCHALL will match the regular expression as  many	 times
	      as  possible  and	 store the matches in the output variable as a
	      list.

	      REGEX REPLACE will match the regular expression as many times as
	      possible and substitute the replacement expression for the match
	      in the output.  The replace expression may refer to paren-delim‐
	      ited  subexpressions  of	the match using \1, \2, ..., \9.  Note
	      that two backslashes (\\1) are required in CMake code to	get  a
	      backslash through argument parsing.

	      REPLACE  will  replace  all  occurrences	of match_string in the
	      input with replace_string and store the result in the output.

	      MD5, SHA1, SHA224, SHA256, SHA384, and  SHA512  will  compute  a
	      cryptographic hash of the input string.

	      COMPARE EQUAL/NOTEQUAL/LESS/GREATER will compare the strings and
	      store true or false in the output variable.

	      ASCII will convert all numbers into corresponding ASCII  charac‐
	      ters.

	      CONFIGURE will transform a string like CONFIGURE_FILE transforms
	      a file.

	      TOUPPER/TOLOWER will convert string to upper/lower characters.

	      LENGTH will return a given string's length.

	      SUBSTRING will return a substring of a given string.  If	length
	      is  -1  the  remainder  of  the string starting at begin will be
	      returned.

	      STRIP will return a substring of a given string with leading and
	      trailing spaces removed.

	      RANDOM will return a random string of given length consisting of
	      characters from the given alphabet. Default length is 5  charac‐
	      ters  and	 default  alphabet  is all numbers and upper and lower
	      case letters.  If an integer RANDOM_SEED	is  given,  its	 value
	      will be used to seed the random number generator.

	      FIND  will  return  the  position	 where the given substring was
	      found in the supplied string. If the REVERSE flag was used,  the
	      command  will  search for the position of the last occurrence of
	      the specified substring.

	      The following characters have special meaning in regular expres‐
	      sions:

		 ^	   Matches at beginning of input
		 $	   Matches at end of input
		 .	   Matches any single character
		 [ ]	   Matches any character(s) inside the brackets
		 [^ ]	   Matches any character(s) not inside the brackets
		  -	   Inside brackets, specifies an inclusive range between
			   characters on either side e.g. [a-f] is [abcdef]
			   To match a literal - using brackets, make it the first
			   or the last character e.g. [+*/-] matches basic
			   mathematical operators.
		 *	   Matches preceding pattern zero or more times
		 +	   Matches preceding pattern one or more times
		 ?	   Matches preceding pattern zero or once only
		 |	   Matches a pattern on either side of the |
		 ()	   Saves a matched subexpression, which can be referenced
			   in the REGEX REPLACE operation. Additionally it is saved
			   by all regular expression-related commands, including
			   e.g. if( MATCHES ), in the variables CMAKE_MATCH_(0..9).

	      *,  +  and  ?  have  higher precedence than concatenation. | has
	      lower precedence than concatenation. This means that the regular
	      expression "^ab+d$" matches "abbd" but not "ababd", and the reg‐
	      ular expression "^(ab|cd)$" matches "ab" but not "abd".

	      TIMESTAMP will write a string representation of the current date
	      and/or time to the output variable.

	      Should  the  command  be unable to obtain a timestamp the output
	      variable will be set to the empty string "".

	      The optional UTC flag requests the current date/time representa‐
	      tion to be in Coordinated Universal Time (UTC) rather than local
	      time.

	      The optional <format string> may contain	the  following	format
	      specifiers:

		 %d	   The day of the current month (01-31).
		 %H	   The hour on a 24-hour clock (00-23).
		 %I	   The hour on a 12-hour clock (01-12).
		 %j	   The day of the current year (001-366).
		 %m	   The month of the current year (01-12).
		 %M	   The minute of the current hour (00-59).
		 %S	   The second of the current minute.
			   60 represents a leap second. (00-60)
		 %U	   The week number of the current year (00-53).
		 %w	   The day of the current week. 0 is Sunday. (0-6)
		 %y	   The last two digits of the current year (00-99)
		 %Y	   The current year.

	      Unknown format specifiers will be ignored and copied to the out‐
	      put as-is.

	      If no explicit <format string> is given it will default to:

		 %Y-%m-%dT%H:%M:%S    for local time.
		 %Y-%m-%dT%H:%M:%SZ   for UTC.

	      MAKE_C_IDENTIFIER will write a string which can be  used	as  an
	      identifier in C.

       target_compile_definitions
	      Add compile definitions to a target.

		target_compile_definitions(<target> <INTERFACE|PUBLIC|PRIVATE> [items1...]
		  [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])

	      Specify  compile	definitions to use when compiling a given tar‐
	      get.  The named <target> must have been  created	by  a  command
	      such  as	add_executable	or  add_library	 and  must  not	 be an
	      IMPORTED target.	The INTERFACE, PUBLIC and PRIVATE keywords are
	      required	to specify the scope of the following arguments.  PRI‐
	      VATE and PUBLIC  items  will  populate  the  COMPILE_DEFINITIONS
	      property	of <target>.  PUBLIC and INTERFACE items will populate
	      the INTERFACE_COMPILE_DEFINITIONS property  of  <target>.	   The
	      following arguments specify compile definitions.	Repeated calls
	      for the same <target> append items in the order called.

	      Arguments	 to  target_compile_definitions	 may  use   "generator
	      expressions"  with  the  syntax "$<...>".	 Generator expressions
	      are evaluated during build system generation to produce informa‐
	      tion  specific  to  each build configuration.  Valid expressions
	      are:

		$<0:...>		  = empty string (ignores "...")
		$<1:...>		  = content of "..."
		$<CONFIG:cfg>		  = '1' if config is "cfg", else '0'
		$<CONFIGURATION>	  = configuration name
		$<BOOL:...>		  = '1' if the '...' is true, else '0'
		$<STREQUAL:a,b>		  = '1' if a is STREQUAL b, else '0'
		$<ANGLE-R>		  = A literal '>'. Used to compare strings which contain a '>' for example.
		$<COMMA>		  = A literal ','. Used to compare strings which contain a ',' for example.
		$<SEMICOLON>		  = A literal ';'. Used to prevent list expansion on an argument with ';'.
		$<JOIN:list,...>	  = joins the list with the content of "..."
		$<TARGET_NAME:...>	  = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.	The '...' must be a literal name of a target- it may not contain generator expressions.
		$<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
		$<BUILD_INTERFACE:...>	  = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
		$<C_COMPILER_ID>	  = The CMake-id of the C compiler used.
		$<C_COMPILER_ID:comp>	  = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.

       target_link_libraries
	      Link a target to given libraries.

		target_link_libraries(<target> [item1 [item2 [...]]]
				      [[debug|optimized|general] <item>] ...)

	      Specify  libraries  or flags to use when linking a given target.
	      The named <target> must have been created in the current	direc‐
	      tory  by	a  command such as add_executable or add_library.  The
	      remaining arguments specify library names	 or  flags.   Repeated
	      calls for the same <target> append items in the order called.

	      If  a library name matches that of another target in the project
	      a dependency will automatically be added in the build system  to
	      make sure the library being linked is up-to-date before the tar‐
	      get links.  Item names  starting	with  '-',  but	 not  '-l'  or
	      '-framework', are treated as linker flags.

	      A	 "debug", "optimized", or "general" keyword indicates that the
	      library immediately following it is to be used only for the cor‐
	      responding build configuration.  The "debug" keyword corresponds
	      to the Debug configuration (or to configurations	named  in  the
	      DEBUG_CONFIGURATIONS  global property if it is set).  The "opti‐
	      mized" keyword corresponds to  all  other	 configurations.   The
	      "general"	 keyword  corresponds  to  all	configurations, and is
	      purely optional (assumed if omitted).  Higher granularity may be
	      achieved	for per-configuration rules by creating and linking to
	      IMPORTED	library	 targets.   See	 the  IMPORTED	mode  of   the
	      add_library command for more information.

	      Library  dependencies are transitive by default.	When this tar‐
	      get is linked into another target then the libraries  linked  to
	      this  target  will  appear on the link line for the other target
	      too.  See the INTERFACE_LINK_LIBRARIES target property to	 over‐
	      ride  the	 set  of  transitive  link  dependencies for a target.
	      Calls to other signatures of this command may set	 the  property
	      making  any  libraries linked exclusively by this signature pri‐
	      vate.

	      CMake will  also	propagate  "usage  requirements"  from	linked
	      library  targets.	  Usage	 requirements  affect  compilation  of
	      sources in the  <target>.	  They	are  specified	by  properties
	      defined  on linked targets.  During generation of the build sys‐
	      tem, CMake integrates usage requirement property values with the
	      corresponding build properties for <target>:

	       INTERFACE_COMPILE_DEFINITONS: Appends to COMPILE_DEFINITONS
	       INTERFACE_INCLUDE_DIRECTORIES: Appends to INCLUDE_DIRECTORIES
	       INTERFACE_POSITION_INDEPENDENT_CODE: Sets POSITION_INDEPENDENT_CODE
		 or checked for consistency with existing value

	      If  an  <item>  is  a library in a Mac OX framework, the Headers
	      directory of the framework will also be processed	 as  a	"usage
	      requirement".  This has the same effect as passing the framework
	      directory as an include directory.   target_link_libraries(<tar‐
	      get>

				    <PRIVATE|PUBLIC|INTERFACE> <lib> ...
				    [<PRIVATE|PUBLIC|INTERFACE> <lib> ... ] ...])

	      The  PUBLIC, PRIVATE and INTERFACE keywords can be used to spec‐
	      ify both the link dependencies and the  link  interface  in  one
	      command.	 Libraries and targets following PUBLIC are linked to,
	      and are made part of the link interface.	Libraries and  targets
	      following	 PRIVATE  are  linked to, but are not made part of the
	      link interface.  Libraries following INTERFACE are  appended  to
	      the link interface and are not used for linking <target>.

		target_link_libraries(<target> LINK_INTERFACE_LIBRARIES
				      [[debug|optimized|general] <lib>] ...)

	      The  LINK_INTERFACE_LIBRARIES  mode appends the libraries to the
	      INTERFACE_LINK_LIBRARIES target property instead of  using  them
	      for  linking.  If policy CMP0022 is not NEW, then this mode also
	      appends  libraries  to  the  LINK_INTERFACE_LIBRARIES  and   its
	      per-configuration equivalent.  This signature is for compatibil‐
	      ity only. Prefer the INTERFACE mode instead.   Libraries	speci‐
	      fied  as "debug" are wrapped in a generator expression to corre‐
	      spond to debug builds.   If  policy  CMP0022  is	not  NEW,  the
	      libraries	   are	  also	  appended    to    the	   LINK_INTER‐
	      FACE_LIBRARIES_DEBUG property (or to the properties  correspond‐
	      ing  to configurations listed in the DEBUG_CONFIGURATIONS global
	      property if it is set).  Libraries specified as "optimized"  are
	      appended	to  the	 INTERFACE_LINK_LIBRARIES property.  If policy
	      CMP0022 is not NEW, they are also appended  to  the  LINK_INTER‐
	      FACE_LIBRARIES  property.	  Libraries specified as "general" (or
	      without any keyword)  are	 treated  as  if  specified  for  both
	      "debug" and "optimized".

		target_link_libraries(<target>
				      <LINK_PRIVATE|LINK_PUBLIC>
					[[debug|optimized|general] <lib>] ...
				      [<LINK_PRIVATE|LINK_PUBLIC>
					[[debug|optimized|general] <lib>] ...])

	      The  LINK_PUBLIC	and  LINK_PRIVATE modes can be used to specify
	      both the link dependencies and the link interface	 in  one  com‐
	      mand.  This signature is for compatibility only. Prefer the PUB‐
	      LIC or PRIVATE keywords instead.	Libraries and targets  follow‐
	      ing  LINK_PUBLIC	are linked to, and are made part of the INTER‐
	      FACE_LINK_LIBRARIES.  If policy CMP0022 is  not  NEW,  they  are
	      also  made  part of the LINK_INTERFACE_LIBRARIES.	 Libraries and
	      targets following LINK_PRIVATE are linked to, but are  not  made
	      part    of    the	  INTERFACE_LINK_LIBRARIES   (or   LINK_INTER‐
	      FACE_LIBRARIES).

	      The library dependency graph is normally acyclic (a DAG), but in
	      the case of mutually-dependent STATIC libraries CMake allows the
	      graph to contain cycles (strongly connected  components).	  When
	      another  target  links to one of the libraries CMake repeats the
	      entire connected component.  For example, the code

		add_library(A STATIC a.c)
		add_library(B STATIC b.c)
		target_link_libraries(A B)
		target_link_libraries(B A)
		add_executable(main main.c)
		target_link_libraries(main A)

	      links 'main' to 'A B A B'.  (While  one  repetition  is  usually
	      sufficient, pathological object file and symbol arrangements can
	      require more.  One may handle such cases by  manually  repeating
	      the  component in the last target_link_libraries call.  However,
	      if two archives are really so interdependent they should	proba‐
	      bly be combined into a single archive.)

	      Arguments	 to  target_link_libraries  may use "generator expres‐
	      sions" with the syntax "$<...>".	Note however,  that  generator
	      expressions  will	 not  be  used	in  OLD handling of CMP0003 or
	      CMP0004.

	      Generator expressions are evaluated during build system  genera‐
	      tion  to	produce	 information specific to each build configura‐
	      tion.  Valid expressions are:

			    [OUTPUT_VARIABLE <var>])

	      Try  building  a project.	 In this form, srcdir should contain a
	      complete CMake  project  with  a	CMakeLists.txt	file  and  all
	      sources.	The  bindir  and srcdir will not be deleted after this
	      command is run. Specify targetName to build  a  specific	target
	      instead of the 'all' or 'ALL_BUILD' target.

		try_compile(RESULT_VAR <bindir> <srcfile|SOURCES srcfile...>
			    [CMAKE_FLAGS flags...]
			    [COMPILE_DEFINITIONS flags...]
			    [LINK_LIBRARIES libs...]
			    [OUTPUT_VARIABLE <var>]
			    [COPY_FILE <fileName> [COPY_FILE_ERROR <var>]])

	      Try  building  an	 executable from one or more source files.  In
	      this form the user need only supply one  or  more	 source	 files
	      that  include  a	definition  for	 'main'.   CMake will create a
	      CMakeLists.txt file to build the	source(s)  as  an  executable.
	      Specify  COPY_FILE to get a copy of the linked executable at the
	      given fileName and optionally  COPY_FILE_ERROR  to  capture  any
	      error.

	      In  this version all files in bindir/CMakeFiles/CMakeTmp will be
	      cleaned automatically. For debugging, --debug-trycompile can  be
	      passed  to  cmake to avoid this clean. However, multiple sequen‐
	      tial try_compile operations reuse this single output  directory.
	      If  you  use --debug-trycompile, you can only debug one try_com‐
	      pile call at a time. The recommended procedure is	 to  configure
	      with cmake all the way through once, then delete the cache entry
	      associated with the  try_compile	call  of  interest,  and  then
	      re-run cmake again with --debug-trycompile.

	      Some extra flags that can be included are,  INCLUDE_DIRECTORIES,
	      LINK_DIRECTORIES, and LINK_LIBRARIES.   COMPILE_DEFINITIONS  are
	      -Ddefinition that will be passed to the compile line.

	      The  srcfile  signature  also  accepts a LINK_LIBRARIES argument
	      which may contain a list of libraries or IMPORTED targets	 which
	      will  be	linked to in the generated project.  If LINK_LIBRARIES
	      is  specified  as	 a  parameter	to   try_compile,   then   any
	      LINK_LIBRARIES passed as CMAKE_FLAGS will be ignored.

	      try_compile  creates  a CMakeList.txt file on the fly that looks
	      like this:

		add_definitions( <expanded COMPILE_DEFINITIONS from calling cmake>)
		include_directories(${INCLUDE_DIRECTORIES})
		link_directories(${LINK_DIRECTORIES})
		add_executable(cmTryCompileExec sources)
		target_link_libraries(cmTryCompileExec ${LINK_LIBRARIES})

	      In both versions of the command, if  OUTPUT_VARIABLE  is	speci‐
	      fied,  then  the	output from the build process is stored in the
	      given variable. The success or failure of the try_compile,  i.e.
	      TRUE   or	  FALSE	  respectively,	 is  returned  in  RESULT_VAR.
	      CMAKE_FLAGS can be used to pass -DVAR:TYPE=VALUE	flags  to  the
	      cmake  that is run during the build. Set variable CMAKE_TRY_COM‐
	      PILE_CONFIGURATION to choose a build configuration.

       try_run
	      Try compiling and then running some code.

		try_run(RUN_RESULT_VAR COMPILE_RESULT_VAR
			bindir srcfile [CMAKE_FLAGS <Flags>]
			[COMPILE_DEFINITIONS <flags>]
			[COMPILE_OUTPUT_VARIABLE comp]
			[RUN_OUTPUT_VARIABLE run]
			[OUTPUT_VARIABLE var]
			[ARGS <arg1> <arg2>...])

	      Try compiling a srcfile.	Return TRUE or FALSE  for  success  or
	      failure  in  COMPILE_RESULT_VAR.	Then if the compile succeeded,
	      run the executable and return its exit code  in  RUN_RESULT_VAR.
	      If   the	 executable   was  built,  but	failed	to  run,  then
	      RUN_RESULT_VAR  will  be	set  to	 FAILED_TO_RUN.	  COMPILE_OUT‐
	      PUT_VARIABLE  specifies  the  variable where the output from the
	      compile step goes. RUN_OUTPUT_VARIABLE  specifies	 the  variable
	      where the output from the running executable goes.

	      For  compatibility  reasons  OUTPUT_VARIABLE is still supported,
	      which gives you the output from the compile and  run  step  com‐
	      bined.

	      Cross compiling issues

	      When  cross compiling, the executable compiled in the first step
	      usually cannot be run on the build host.	try_run()  checks  the
	      CMAKE_CROSSCOMPILING  variable  to  detect  whether  CMake is in
	      crosscompiling mode. If that's the case, it will	still  try  to
	      compile  the  executable,	 but  it  will not try to run the exe‐
	      cutable. Instead it will create cache variables  which  must  be
	      filled  by  the  user or by presetting them in some CMake script
	      file to the values the executable would have produced if it  had
	      been  run	 on  its  actual  target platform. These variables are
	      RUN_RESULT_VAR (explanation see above) and  if  RUN_OUTPUT_VARI‐
	      ABLE (or OUTPUT_VARIABLE) was used, an additional cache variable
	      RUN_RESULT_VAR__COMPILE_RESULT_VAR__TRYRUN_OUTPUT.This	    is
	      intended to hold stdout and stderr from the executable.

	      In  order	 to  make  cross  compiling  your  project easier, use
	      try_run only  if	really	required.  If  you  use	 try_run,  use
	      RUN_OUTPUT_VARIABLE   (or	  OUTPUT_VARIABLE)   only   if	really
	      required. Using them will require that when crosscompiling,  the
	      cache  variables	will  have to be set manually to the output of
	      the executable. You can also "guard" the calls to	 try_run  with
	      if(CMAKE_CROSSCOMPILING)	and provide an easy-to-preset alterna‐
	      tive for this case.

	      Set variable CMAKE_TRY_COMPILE_CONFIGURATION to choose  a	 build
	      configuration.

       unset  Unset a variable, cache variable, or environment variable.

		unset(<variable> [CACHE])

	      Removes  the  specified variable causing it to become undefined.
	      If CACHE is present then the variable is removed from the	 cache
	      instead of the current scope.

	      <variable> can be an environment variable such as:

		unset(ENV{LD_LIBRARY_PATH})

	      in  which	 case  the  variable  will be removed from the current
	      environment.

       variable_watch
	      Watch the CMake variable for change.

		variable_watch(<variable name> [<command to execute>])

	      If the specified variable changes, the message will  be  printed
	      about  the  variable being changed. If the command is specified,
	      the command will be executed. The command will receive the  fol‐
	      lowing  arguments:  COMMAND(<variable> <access> <value> <current
	      list file> <stack>)

       while  Evaluate a group of commands while a condition is true

		while(condition)
		  COMMAND1(ARGS ...)
		  COMMAND2(ARGS ...)
		  ...
		endwhile(condition)

	      All  commands  between  while  and  the  matching	 endwhile  are
	      recorded without being invoked.  Once the endwhile is evaluated,
	      the recorded list of commands is invoked as long as  the	condi‐
	      tion is true. The condition is evaluated using the same logic as
	      the if command.

PROPERTIES
	 CMake Properties - Properties supported by CMake, the Cross-Platform Makefile Generator.

       This is the documentation for the properties supported by CMake.	 Prop‐
       erties  can  have  different  scopes.  They can either be assigned to a
       source file, a directory, a target or globally to CMake.	 By  modifying
       the  values of properties the behaviour of the build system can be cus‐
       tomized.

PROPERTIES OF GLOBAL SCOPE
       ALLOW_DUPLICATE_CUSTOM_TARGETS
	      Allow duplicate custom targets to be created.

	      Normally CMake requires that all targets built in a project have
	      globally	unique	logical	 names	(see policy CMP0002).  This is
	      necessary to generate meaningful project file names in Xcode and
	      VS IDE generators.  It also allows the target names to be refer‐
	      enced unambiguously.

	      Makefile generators are capable of supporting  duplicate	custom
	      target names.  For projects that care only about Makefile gener‐
	      ators and do not wish to support Xcode or VS IDE generators, one
	      may set this property to true to allow duplicate custom targets.
	      The property allows multiple add_custom_target command calls  in
	      different directories to specify the same target name.  However,
	      setting this property will cause non-Makefile generators to pro‐
	      duce an error and refuse to generate the project.

       AUTOMOC_TARGETS_FOLDER
	      Name  of	FOLDER	for *_automoc targets that are added automati‐
	      cally by CMake for targets for which AUTOMOC is enabled.

	      If not set, CMake uses the FOLDER property of the parent	target
	      as a default value for this property. See also the documentation
	      for the FOLDER target property and the AUTOMOC target property.

       DEBUG_CONFIGURATIONS
	      Specify which configurations are for debugging.

	      The value must be a semi-colon separated list  of	 configuration
	      names.   Currently  this	property  is  used  only  by  the tar‐
	      get_link_libraries command (see its documentation for  details).
	      Additional uses may be defined in the future.

	      This  property  must  be set at the top level of the project and
	      before the first target_link_libraries command  invocation.   If
	      any  entry  in the list does not match a valid configuration for
	      the project the behavior is undefined.

       DISABLED_FEATURES
	      List of features which are disabled during the CMake run.

	      List of features which are disabled during  the  CMake  run.  By
	      default  it  contains  the  names of all packages which were not
	      found. This is  determined  using	 the  <NAME>_FOUND  variables.
	      Packages	which are searched QUIET are not listed. A project can
	      add its own features to this list. This property is used by  the
	      macros in FeatureSummary.cmake.

       ENABLED_FEATURES
	      List of features which are enabled during the CMake run.

	      List  of	features  which	 are  enabled during the CMake run. By
	      default it contains the names of all packages which were	found.
	      This  is	determined  using the <NAME>_FOUND variables. Packages
	      which are searched QUIET are not listed. A project can  add  its
	      own  features  to this list. This property is used by the macros
	      in FeatureSummary.cmake.

       ENABLED_LANGUAGES
	      Read-only property that contains the list of  currently  enabled
	      languages

	      Set to list of currently enabled languages.

       FIND_LIBRARY_USE_LIB64_PATHS
	      Whether  FIND_LIBRARY should automatically search lib64 directo‐
	      ries.

	      FIND_LIBRARY_USE_LIB64_PATHS is a boolean specifying whether the
	      FIND_LIBRARY command should automatically search the lib64 vari‐
	      ant of directories called lib in the search path	when  building
	      64-bit binaries.

       FIND_LIBRARY_USE_OPENBSD_VERSIONING
	      Whether FIND_LIBRARY should find OpenBSD-style shared libraries.

	      This  property  is a boolean specifying whether the FIND_LIBRARY
	      command should find shared  libraries  with  OpenBSD-style  ver‐
	      sioned extension: ".so.<major>.<minor>".	The property is set to
	      true on OpenBSD and false on other platforms.

       GLOBAL_DEPENDS_DEBUG_MODE
	      Enable global target dependency graph debug mode.

	      CMake automatically analyzes the global inter-target  dependency
	      graph  at the beginning of native build system generation.  This
	      property causes it to display details of its analysis to stderr.

       GLOBAL_DEPENDS_NO_CYCLES
	      Disallow global target dependency graph cycles.

	      CMake automatically analyzes the global inter-target  dependency
	      graph  at	 the  beginning of native build system generation.  It
	      reports an error if the dependency graph contains a  cycle  that
	      does  not	 consist of all STATIC library targets.	 This property
	      tells CMake to disallow all cycles completely, even among static
	      libraries.

       IN_TRY_COMPILE
	      Read-only	 property that is true during a try-compile configura‐
	      tion.

	      True when building a project inside  a  TRY_COMPILE  or  TRY_RUN
	      command.

       PACKAGES_FOUND
	      List of packages which were found during the CMake run.

	      List  of packages which were found during the CMake run. Whether
	      a package has been found is determined  using  the  <NAME>_FOUND
	      variables.

       PACKAGES_NOT_FOUND
	      List of packages which were not found during the CMake run.

	      List  of	packages  which	 were  not found during the CMake run.
	      Whether a	 package  has  been  found  is	determined  using  the
	      <NAME>_FOUND variables.

       PREDEFINED_TARGETS_FOLDER
	      Name  of	FOLDER	for  targets  that  are added automatically by
	      CMake.

	      If not set, CMake uses  "CMakePredefinedTargets"	as  a  default
	      value  for  this	property. Targets such as INSTALL, PACKAGE and
	      RUN_TESTS will be organized into this FOLDER. See also the docu‐
	      mentation for the FOLDER target property.

       REPORT_UNDEFINED_PROPERTIES
	      If set, report any undefined properties to this file.

	      If  this	property  is set to a filename then when CMake runs it
	      will report any properties or variables that were	 accessed  but
	      not defined into the filename specified in this property.

       RULE_LAUNCH_COMPILE
	      Specify a launcher for compile rules.

	      Makefile	generators  prefix  compiler  commands	with the given
	      launcher command line.  This is intended to allow	 launchers  to
	      intercept	 build	problems  with high granularity.  Non-Makefile
	      generators currently ignore this property.

       RULE_LAUNCH_CUSTOM
	      Specify a launcher for custom rules.

	      Makefile	generators  prefix  custom  commands  with  the	 given
	      launcher	command	 line.	This is intended to allow launchers to
	      intercept build problems with  high  granularity.	  Non-Makefile
	      generators currently ignore this property.

       RULE_LAUNCH_LINK
	      Specify a launcher for link rules.

	      Makefile	generators  prefix  link and archive commands with the
	      given launcher command line.  This is intended to allow  launch‐
	      ers   to	 intercept   build  problems  with  high  granularity.
	      Non-Makefile generators currently ignore this property.

       RULE_MESSAGES
	      Specify whether to report a message for each make rule.

	      This property specifies whether Makefile generators should add a
	      progress	message	 describing what each build rule does.	If the
	      property is not set the default is ON.  Set the property to  OFF
	      to disable granular messages and report only as each target com‐
	      pletes.  This is intended to allow scripted builds to avoid  the
	      build  time  cost of detailed reports.  If a CMAKE_RULE_MESSAGES
	      cache entry exists its value initializes the value of this prop‐
	      erty.  Non-Makefile generators currently ignore this property.

       TARGET_ARCHIVES_MAY_BE_SHARED_LIBS
	      Set if shared libraries may be named like archives.

	      On  AIX shared libraries may be named "lib<name>.a".  This prop‐
	      erty is set to true on such platforms.

       TARGET_SUPPORTS_SHARED_LIBS
	      Does the target platform support shared libraries.

	      TARGET_SUPPORTS_SHARED_LIBS is a boolean specifying whether  the
	      target platform supports shared libraries. Basically all current
	      general general purpose OS do  so,  the  exception  are  usually
	      embedded systems with no or special OSs.

       USE_FOLDERS
	      Use the FOLDER target property to organize targets into folders.

	      If  not set, CMake treats this property as OFF by default. CMake
	      generators that are capable of organizing into  a	 hierarchy  of
	      folders  use  the	 values	 of the FOLDER target property to name
	      those folders. See also the documentation for the FOLDER	target
	      property.

       __CMAKE_DELETE_CACHE_CHANGE_VARS_
	      Internal property

	      Used to detect compiler changes, Do not set.

PROPERTIES ON DIRECTORIES
       ADDITIONAL_MAKE_CLEAN_FILES
	      Additional files to clean during the make clean stage.

	      A	 list  of  files  that	will be cleaned as a part of the "make
	      clean" stage.

       CACHE_VARIABLES
	      List of cache variables available in the current directory.

	      This read-only property specifies the list of CMake cache	 vari‐
	      ables currently defined.	It is intended for debugging purposes.

       CLEAN_NO_CUSTOM
	      Should the output of custom commands be left.

	      If  this	is  true  then the outputs of custom commands for this
	      directory will not be removed during the "make clean" stage.

       COMPILE_DEFINITIONS
	      Preprocessor definitions for compiling a directory's sources.

	      The COMPILE_DEFINITIONS property may be set to a semicolon-sepa‐
	      rated  list  of preprocessor definitions using the syntax VAR or
	      VAR=value.  Function-style definitions are not supported.	 CMake
	      will  automatically  escape  the	value correctly for the native
	      build system  (note  that	 CMake	language  syntax  may  require
	      escapes  to specify some values).	 This property may be set on a
	      per-configuration basis using the name COMPILE_DEFINITIONS_<CON‐
	      FIG>  where <CONFIG> is an upper-case name (ex. "COMPILE_DEFINI‐
	      TIONS_DEBUG").  This property will be initialized in each direc‐
	      tory by its value in the directory's parent.

	      CMake will automatically drop some definitions that are not sup‐
	      ported by the native build tool.	The VS6 IDE does  not  support
	      definition values with spaces (but NMake does).

	      Disclaimer: Most native build tools have poor support for escap‐
	      ing certain values.  CMake has work-arounds for many  cases  but
	      some  values  may	 just not be possible to pass correctly.  If a
	      value does not seem to be escaped correctly, do not  attempt  to
	      work-around the problem by adding escape sequences to the value.
	      Your work-around may break in a future version of CMake that has
	      improved escape support.	Instead consider defining the macro in
	      a (configured) header file.  Then report the limitation.	 Known
	      limitations include:

		#	   - broken almost everywhere
		;	   - broken in VS IDE 7.0 and Borland Makefiles
		,	   - broken in VS IDE
		%	   - broken in some cases in NMake
		& |	   - broken in some cases on MinGW
		^ < > \"   - broken in most Make tools on Windows

	      CMake does not reject these values outright because they do work
	      in some cases.  Use with caution.

       COMPILE_DEFINITIONS_<CONFIG>
	      Per-configuration preprocessor definitions in a directory.

	      This is the configuration-specific  version  of  COMPILE_DEFINI‐
	      TIONS.   This  property will be initialized in each directory by
	      its value in the directory's parent.

       COMPILE_OPTIONS
	      List of options to pass to the compiler.

	      This property specifies the list of directories given so far for
	      this property.  This property exists on directories and targets.

	      The target property values are used by the generators to set the
	      options for the compiler.

	      Contents of COMPILE_OPTIONS may use "generator expressions" with
	      the syntax "$<...>".  Generator expressions are evaluated during
	      build system generation to produce information specific to  each
	      build configuration.  Valid expressions are:

		$<0:...>		  = empty string (ignores "...")
		$<1:...>		  = content of "..."
		$<CONFIG:cfg>		  = '1' if config is "cfg", else '0'
		$<CONFIGURATION>	  = configuration name
		$<BOOL:...>		  = '1' if the '...' is true, else '0'
		$<STREQUAL:a,b>		  = '1' if a is STREQUAL b, else '0'
		$<ANGLE-R>		  = A literal '>'. Used to compare strings which contain a '>' for example.
		$<COMMA>		  = A literal ','. Used to compare strings which contain a ',' for example.
		$<SEMICOLON>		  = A literal ';'. Used to prevent list expansion on an argument with ';'.
		$<JOIN:list,...>	  = joins the list with the content of "..."
		$<TARGET_NAME:...>	  = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.	The '...' must be a literal name of a target- it may not contain generator expressions.
		$<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
		$<BUILD_INTERFACE:...>	  = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
		$<C_COMPILER_ID>	  = The CMake-id of the C compiler used.
		$<C_COMPILER_ID:comp>	  = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
		$<CXX_COMPILER_ID>	  = The CMake-id of the CXX compiler used.
		$<CXX_COMPILER_ID:comp>	  = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
		$<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
		$<VERSION_LESS:v1,v2>	  = '1' if v1 is a version less than v2, else '0'.
		$<VERSION_EQUAL:v1,v2>	  = '1' if v1 is the same version as v2, else '0'.
		$<C_COMPILER_VERSION>	  = The version of the C compiler used.
		$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
		$<CXX_COMPILER_VERSION>	  = The version of the CXX compiler used.
		$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
		$<TARGET_FILE:tgt>	  = main file (.exe, .so.1.2, .a)
		$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
		$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

	      where  "tgt"  is	the name of a target.  Target file expressions
	      produce a full path, but _DIR and _NAME versions can produce the
	      directory and file name components:

		$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
		$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
		$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

		$<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

	      Note  that  tgt  is not added as a dependency of the target this
	      expression is evaluated on.

		$<TARGET_POLICY:pol>	      = '1' if the policy was NEW when the 'head' target was created, else '0'.	 If the policy was not set, the warning message for the policy will be emitted.	 This generator expression only works for a subset of policies.
		$<INSTALL_PREFIX>	  = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

	      Boolean expressions:

		$<AND:?[,?]...>		  = '1' if all '?' are '1', else '0'
		$<OR:?[,?]...>		  = '0' if all '?' are '0', else '1'
		$<NOT:?>		  = '0' if '?' is '1', else '1'

	      where '?' is always either '0' or '1'.

	      Expressions with an implicit 'this' target:

		$<TARGET_PROPERTY:prop>	  = The value of the property prop on the target on which the generator expression is evaluated.

       DEFINITIONS
	      For  CMake  2.4  compatibility  only.   Use  COMPILE_DEFINITIONS
	      instead.

	      This read-only property specifies the list of flags given so far
	      to the add_definitions command.  It is  intended	for  debugging
	      purposes.	 Use the COMPILE_DEFINITIONS instead.

       EXCLUDE_FROM_ALL
	      Exclude the directory from the all target of its parent.

	      A	 property  on  a  directory  that indicates if its targets are
	      excluded from the default build target. If it is not, then  with
	      a	 Makefile for example typing make will cause the targets to be
	      built. The same concept applies to the default  build  of	 other
	      generators.

       IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
	      Specify  #include	 line  transforms for dependencies in a direc‐
	      tory.

	      This property specifies rules to transform  macro-like  #include
	      lines  during  implicit  dependency scanning of C and C++ source
	      files.  The list of rules must be semicolon-separated with  each
	      entry  of the form "A_MACRO(%)=value-with-%" (the % must be lit‐
	      eral).  During dependency scanning occurrences  of  A_MACRO(...)
	      on  #include  lines will be replaced by the value given with the
	      macro argument substituted for '%'.  For example, the entry

		MYDIR(%)=<mydir/%>

	      will convert lines of the form

		#include MYDIR(myheader.h)

	      to

		#include <mydir/myheader.h>

	      allowing the dependency to be followed.

	      This property applies to sources in all targets within a	direc‐
	      tory.   The  property  value is initialized in each directory by
	      its value in the directory's parent.

       INCLUDE_DIRECTORIES
	      List of preprocessor include file search directories.

	      This property specifies the list of directories given so far  to
	      the include_directories command.	This property exists on direc‐
	      tories and targets.  In addition to accepting  values  from  the
	      include_directories  command,  values may be set directly on any
	      directory or any target using the set_property command.  A  tar‐
	      get  gets	 its initial value for this property from the value of
	      the directory property.  A directory gets its initial value from
	      its  parent  directory if it has one.  Both directory and target
	      property values are adjusted by calls to the include_directories
	      command.

	      The target property values are used by the generators to set the
	      include paths for the compiler.  See also	 the  include_directo‐
	      ries command.

       INCLUDE_REGULAR_EXPRESSION
	      Include file scanning regular expression.

	      This  read-only  property	 specifies the regular expression used
	      during dependency scanning to match include files that should be
	      followed.	 See the include_regular_expression command.

       INTERPROCEDURAL_OPTIMIZATION
	      Enable interprocedural optimization for targets in a directory.

	      If  set  to  true, enables interprocedural optimizations if they
	      are known to be supported by the compiler.

       INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
	      Per-configuration interprocedural optimization for a directory.

	      This is a per-configuration version of INTERPROCEDURAL_OPTIMIZA‐
	      TION.   If set, this property overrides the generic property for
	      the named configuration.

       LINK_DIRECTORIES
	      List of linker search directories.

	      This read-only property specifies the list of directories	 given
	      so  far  to  the	link_directories  command.  It is intended for
	      debugging purposes.

       LISTFILE_STACK
	      The current stack of listfiles being processed.

	      This property is mainly useful when trying to  debug  errors  in
	      your  CMake  scripts.  It	 returns a list of what list files are
	      currently being processed, in order. So if one listfile does  an
	      INCLUDE  command	then  that is effectively pushing the included
	      listfile onto the stack.

       MACROS List of macro commands available in the current directory.

	      This read-only property specifies the list of CMake macros  cur‐
	      rently defined.  It is intended for debugging purposes.  See the
	      macro command.

       PARENT_DIRECTORY
	      Source directory that added current subdirectory.

	      This read-only property  specifies  the  source  directory  that
	      added  the  current  source  directory  as a subdirectory of the
	      build.   In  the	top-level   directory	the   value   is   the
	      empty-string.

       RULE_LAUNCH_COMPILE
	      Specify a launcher for compile rules.

	      See  the	global	property  of  the same name for details.  This
	      overrides the global property for a directory.

       RULE_LAUNCH_CUSTOM
	      Specify a launcher for custom rules.

	      See the global property of the  same  name  for  details.	  This
	      overrides the global property for a directory.

       RULE_LAUNCH_LINK
	      Specify a launcher for link rules.

	      See  the	global	property  of  the same name for details.  This
	      overrides the global property for a directory.

       TEST_INCLUDE_FILE
	      A cmake file that will be included when ctest is run.

	      If you specify TEST_INCLUDE_FILE, that file will be included and
	      processed when ctest is run on the directory.

       VARIABLES
	      List of variables defined in the current directory.

	      This  read-only  property	 specifies the list of CMake variables
	      currently defined.  It is intended for debugging purposes.

       VS_GLOBAL_SECTION_POST_<section>
	      Specify a postSolution global section in Visual Studio.

	      Setting a property like this generates an entry of the following
	      form in the solution file:

		GlobalSection(<section>) = postSolution
		  <contents based on property value>
		EndGlobalSection

	      The  property  must  be  set  to	a  semicolon-separated list of
	      key=value pairs. Each such pair  will  be	 transformed  into  an
	      entry  in the solution global section. Whitespace around key and
	      value is ignored. List elements which do not  contain  an	 equal
	      sign are skipped.

	      This  property  only  works for Visual Studio 7 and above; it is
	      ignored on other generators. The property only applies when  set
	      on  a  directory	whose CMakeLists.txt contains a project() com‐
	      mand.

	      Note that CMake generates postSolution  sections	Extensibility‐
	      Globals  and ExtensibilityAddIns by default. If you set the cor‐
	      responding property, it will override the default	 section.  For
	      example,	 setting   VS_GLOBAL_SECTION_POST_ExtensibilityGlobals
	      will override the default contents of  the  ExtensibilityGlobals
	      section, while keeping ExtensibilityAddIns on its default.

       VS_GLOBAL_SECTION_PRE_<section>
	      Specify a preSolution global section in Visual Studio.

	      Setting a property like this generates an entry of the following
	      form in the solution file:

		GlobalSection(<section>) = preSolution
		  <contents based on property value>
		EndGlobalSection

	      The property must	 be  set  to  a	 semicolon-separated  list  of
	      key=value	 pairs.	 Each  such  pair  will be transformed into an
	      entry in the solution global section. Whitespace around key  and
	      value  is	 ignored.  List elements which do not contain an equal
	      sign are skipped.

	      This property only works for Visual Studio 7 and	above;	it  is
	      ignored  on other generators. The property only applies when set
	      on a directory whose CMakeLists.txt contains  a  project()  com‐
	      mand.

PROPERTIES ON TARGETS
       <CONFIG>_OUTPUT_NAME
	      Old per-configuration target file base name.

	      This  is	a  configuration-specific version of OUTPUT_NAME.  Use
	      OUTPUT_NAME_<CONFIG> instead.

       <CONFIG>_POSTFIX
	      Postfix to append to the	target	file  name  for	 configuration
	      <CONFIG>.

	      When  building  with  configuration  <CONFIG>  the value of this
	      property is appended to the target file name built on disk.  For
	      non-executable  targets,	this  property	is  initialized by the
	      value of the variable CMAKE_<CONFIG>_POSTFIX if it is set when a
	      target  is  created.   This  property  is ignored on the Mac for
	      Frameworks and App Bundles.

       <LANG>_VISIBILITY_PRESET
	      Value for symbol visibility compile flags

	      The  <LANG>_VISIBILITY_PRESET  property  determines  the	 value
	      passed  in  a visibility related compile option, such as -fvisi‐
	      bility= for <LANG>.   This  property  only  has  an  affect  for
	      libraries	 and  executables with exports.	 This property is ini‐
	      tialized by the  value  of  the  variable	 CMAKE_<LANG>_VISIBIL‐
	      ITY_PRESET if it is set when a target is created.

       ALIASED_TARGET
	      Name of target aliased by this target.

	      If  this	is an ALIAS target, this property contains the name of
	      the target aliased.

       ARCHIVE_OUTPUT_DIRECTORY
	      Output directory in which to build ARCHIVE target files.

	      This property specifies the directory into which archive	target
	      files  should  be	 built.	 Multi-configuration  generators  (VS,
	      Xcode) append a per-configuration subdirectory to the  specified
	      directory.   There  are  three kinds of target files that may be
	      built: archive, library, and runtime.   Executables  are	always
	      treated  as runtime targets. Static libraries are always treated
	      as archive targets.  Module  libraries  are  always  treated  as
	      library  targets.	 For  non-DLL  platforms  shared libraries are
	      treated as library targets. For DLL platforms the DLL part of  a
	      shared  library  is  treated  as a runtime target and the corre‐
	      sponding import library is treated as  an	 archive  target.  All
	      Windows-based  systems including Cygwin are DLL platforms.  This
	      property is initialized by the value of the  variable  CMAKE_AR‐
	      CHIVE_OUTPUT_DIRECTORY if it is set when a target is created.

       ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
	      Per-configuration output directory for ARCHIVE target files.

	      This is a per-configuration version of ARCHIVE_OUTPUT_DIRECTORY,
	      but multi-configuration generators (VS, Xcode) do NOT  append  a
	      per-configuration subdirectory to the specified directory.  This
	      property is initialized by the value of the  variable  CMAKE_AR‐
	      CHIVE_OUTPUT_DIRECTORY_<CONFIG>  if  it  is set when a target is
	      created.

       ARCHIVE_OUTPUT_NAME
	      Output name for ARCHIVE target files.

	      This property specifies the base name for archive target	files.
	      It  overrides  OUTPUT_NAME  and OUTPUT_NAME_<CONFIG> properties.
	      There are three kinds of target files that  may  be  built:  ar‐
	      chive,  library, and runtime.  Executables are always treated as
	      runtime targets. Static libraries are always treated as  archive
	      targets. Module libraries are always treated as library targets.
	      For non-DLL platforms shared libraries are  treated  as  library
	      targets.	For  DLL platforms the DLL part of a shared library is
	      treated as a runtime target and the corresponding import library
	      is  treated  as  an  archive  target.  All Windows-based systems
	      including Cygwin are DLL platforms.

       ARCHIVE_OUTPUT_NAME_<CONFIG>
	      Per-configuration output name for ARCHIVE target files.

	      This  is	the  configuration-specific  version  of  ARCHIVE_OUT‐
	      PUT_NAME.

       AUTOMOC
	      Should the target be processed with automoc (for Qt projects).

	      AUTOMOC is a boolean specifying whether CMake will handle the Qt
	      moc preprocessor automatically, i.e. without having to  use  the
	      QT4_WRAP_CPP()  or  QT5_WRAP_CPP()  macro. Currently Qt4 and Qt5
	      are supported.  When this property is set to  TRUE,  CMake  will
	      scan  the source files at build time and invoke moc accordingly.
	      If an #include statement like #include "moc_foo.cpp"  is	found,
	      the  Q_OBJECT  class  declaration is expected in the header, and
	      moc is run on the header file. If	 an  #include  statement  like
	      #include	"foo.moc" is found, then a Q_OBJECT is expected in the
	      current source file and moc is run on the file itself. Addition‐
	      ally,  all  header  files are parsed for Q_OBJECT macros, and if
	      found, moc is also executed on those files.  The	resulting  moc
	      files,  which  are  not  included	 as  shown above in any of the
	      source files are	included  in  a	 generated  <targetname>_auto‐
	      moc.cpp file, which is compiled as part of the target.This prop‐
	      erty is initialized by the value of the  variable	 CMAKE_AUTOMOC
	      if it is set when a target is created.

	      Additional command line options for moc can be set via the AUTO‐
	      MOC_MOC_OPTIONS property.

	      By setting the CMAKE_AUTOMOC_RELAXED_MODE variable to  TRUE  the
	      rules for searching the files which will be processed by moc can
	      be relaxed. See the documentation for  this  variable  for  more
	      details.

	      The  global property AUTOMOC_TARGETS_FOLDER can be used to group
	      the automoc targets together in an IDE, e.g. in MSVS.

       AUTOMOC_MOC_OPTIONS
	      Additional options for moc when using automoc (see  the  AUTOMOC
	      property)

	      This  property  is  only	used if the AUTOMOC property is set to
	      TRUE for this target. In this case, it holds additional  command
	      line  options which will be used when moc is executed during the
	      build, i.e. it is equivalent to the optional OPTIONS argument of
	      the qt4_wrap_cpp() macro.

	      By default it is empty.

       BUILD_WITH_INSTALL_RPATH
	      Should build tree targets have install tree rpaths.

	      BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link
	      the target in the build tree with the INSTALL_RPATH.  This takes
	      precedence over SKIP_BUILD_RPATH and avoids the need for relink‐
	      ing before installation.	This property is  initialized  by  the
	      value  of	 the  variable CMAKE_BUILD_WITH_INSTALL_RPATH if it is
	      set when a target is created.

       BUNDLE This target is a CFBundle on the Mac.

	      If a module library target has this property set to true it will
	      be  built	 as a CFBundle when built on the mac. It will have the
	      directory structure required for a CFBundle and will be suitable
	      to  be  used  for	 creating Browser Plugins or other application
	      resources.

       BUNDLE_EXTENSION
	      The file extension used to name a BUNDLE target on the Mac.

	      The default value is "bundle" - you can  also  use  "plugin"  or
	      whatever	file  extension	 is  required by the host app for your
	      bundle.

       COMPATIBLE_INTERFACE_BOOL
	      Properties which must be compatible with their link interface

	      The COMPATIBLE_INTERFACE_BOOL property may  contain  a  list  of
	      propertiesfor  this  target which must be consistent when evalu‐
	      ated as a boolean in the INTERFACE of all linked dependees.  For
	      example,	if a property "FOO" appears in the list, then for each
	      dependee, the "INTERFACE_FOO" property content  in  all  of  its
	      dependencies  must  be  consistent with each other, and with the
	      "FOO" property in the dependee.  Consistency in this  sense  has
	      the  meaning  that if the property is set, then it must have the
	      same boolean value as all others, and if	the  property  is  not
	      set,  then  it is ignored.  Note that for each dependee, the set
	      of properties from this property must not intersect with the set
	      of properties from the COMPATIBLE_INTERFACE_STRING property.

       COMPATIBLE_INTERFACE_STRING
	      Properties  which	 must  be  string-compatible  with  their link
	      interface

	      The COMPATIBLE_INTERFACE_STRING property may contain a  list  of
	      properties for this target which must be the same when evaluated
	      as a string in the INTERFACE of all linked dependees.  For exam‐
	      ple,  if	a  property  "FOO"  appears in the list, then for each
	      dependee, the "INTERFACE_FOO" property content  in  all  of  its
	      dependencies  must  be equal with each other, and with the "FOO"
	      property in the dependee.	 If the property is not set,  then  it
	      is  ignored.  Note that for each dependee, the set of properties
	      from this property must not intersect with the set of properties
	      from the COMPATIBLE_INTERFACE_BOOL property.

       COMPILE_DEFINITIONS
	      Preprocessor definitions for compiling a target's sources.

	      The COMPILE_DEFINITIONS property may be set to a semicolon-sepa‐
	      rated list of preprocessor definitions using the syntax  VAR  or
	      VAR=value.  Function-style definitions are not supported.	 CMake
	      will automatically escape the value  correctly  for  the	native
	      build  system  (note  that  CMake	 language  syntax  may require
	      escapes to specify some values).	This property may be set on  a
	      per-configuration basis using the name COMPILE_DEFINITIONS_<CON‐
	      FIG> where <CONFIG> is an upper-case name (ex.  "COMPILE_DEFINI‐
	      TIONS_DEBUG").

	      CMake will automatically drop some definitions that are not sup‐
	      ported by the native build tool.	The VS6 IDE does  not  support
	      definition values with spaces (but NMake does).

	      Contents	of COMPILE_DEFINITIONS may use "generator expressions"
	      with the syntax "$<...>".	 Generator expressions	are  evaluated
	      during  build  system generation to produce information specific
	      to each build configuration.  Valid expressions are:

		$<0:...>		  = empty string (ignores "...")
		$<1:...>		  = content of "..."
		$<CONFIG:cfg>		  = '1' if config is "cfg", else '0'
		$<CONFIGURATION>	  = configuration name
		$<BOOL:...>		  = '1' if the '...' is true, else '0'
		$<STREQUAL:a,b>		  = '1' if a is STREQUAL b, else '0'
		$<ANGLE-R>		  = A literal '>'. Used to compare strings which contain a '>' for example.
		$<COMMA>		  = A literal ','. Used to compare strings which contain a ',' for example.
		$<SEMICOLON>		  = A literal ';'. Used to prevent list expansion on an argument with ';'.
		$<JOIN:list,...>	  = joins the list with the content of "..."
		$<TARGET_NAME:...>	  = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.	The '...' must be a literal name of a target- it may not contain generator expressions.
		$<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
		$<BUILD_INTERFACE:...>	  = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
		$<C_COMPILER_ID>	  = The CMake-id of the C compiler used.
		$<C_COMPILER_ID:comp>	  = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
		$<CXX_COMPILER_ID>	  = The CMake-id of the CXX compiler used.
		$<CXX_COMPILER_ID:comp>	  = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
		$<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
		$<VERSION_LESS:v1,v2>	  = '1' if v1 is a version less than v2, else '0'.
		$<VERSION_EQUAL:v1,v2>	  = '1' if v1 is the same version as v2, else '0'.
		$<C_COMPILER_VERSION>	  = The version of the C compiler used.
		$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
		$<CXX_COMPILER_VERSION>	  = The version of the CXX compiler used.
		$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
		$<TARGET_FILE:tgt>	  = main file (.exe, .so.1.2, .a)
		$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
		$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

	      where "tgt" is the name of a target.   Target  file  expressions
	      produce a full path, but _DIR and _NAME versions can produce the
	      directory and file name components:

		$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
		$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
		$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

		$<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

	      Note that tgt is not added as a dependency of  the  target  this
	      expression is evaluated on.

		$<TARGET_POLICY:pol>	      = '1' if the policy was NEW when the 'head' target was created, else '0'.	 If the policy was not set, the warning message for the policy will be emitted.	 This generator expression only works for a subset of policies.
		$<INSTALL_PREFIX>	  = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

	      Boolean expressions:

		$<AND:?[,?]...>		  = '1' if all '?' are '1', else '0'
		$<OR:?[,?]...>		  = '0' if all '?' are '0', else '1'
		$<NOT:?>		  = '0' if '?' is '1', else '1'

	      where '?' is always either '0' or '1'.

	      Expressions with an implicit 'this' target:

		$<TARGET_PROPERTY:prop>	  = The value of the property prop on the target on which the generator expression is evaluated.

	      Disclaimer: Most native build tools have poor support for escap‐
	      ing certain values.  CMake has work-arounds for many  cases  but
	      some  values  may	 just not be possible to pass correctly.  If a
	      value does not seem to be escaped correctly, do not  attempt  to
	      work-around the problem by adding escape sequences to the value.
	      Your work-around may break in a future version of CMake that has
	      improved escape support.	Instead consider defining the macro in
	      a (configured) header file.  Then report the limitation.	 Known
	      limitations include:

		#	   - broken almost everywhere
		;	   - broken in VS IDE 7.0 and Borland Makefiles
		,	   - broken in VS IDE
		%	   - broken in some cases in NMake
		& |	   - broken in some cases on MinGW
		^ < > \"   - broken in most Make tools on Windows

	      CMake does not reject these values outright because they do work
	      in some cases.  Use with caution.

       COMPILE_DEFINITIONS_<CONFIG>
	      Per-configuration preprocessor definitions on a target.

	      This is the configuration-specific  version  of  COMPILE_DEFINI‐
	      TIONS.

       COMPILE_FLAGS
	      Additional flags to use when compiling this target's sources.

	      The  COMPILE_FLAGS  property sets additional compiler flags used
	      to build sources within the target.  Use COMPILE_DEFINITIONS  to
	      pass additional preprocessor definitions.

       COMPILE_OPTIONS
	      List of options to pass to the compiler.

	      This property specifies the list of options specified so far for
	      this property.  This property exists on directories and targets.

	      The target property values are used by the generators to set the
	      options for the compiler.

	      Contents of COMPILE_OPTIONS may use "generator expressions" with
	      the syntax "$<...>".  Generator expressions are evaluated during
	      build  system generation to produce information specific to each
	      build configuration.  Valid expressions are:

		$<0:...>		  = empty string (ignores "...")
		$<1:...>		  = content of "..."
		$<CONFIG:cfg>		  = '1' if config is "cfg", else '0'
		$<CONFIGURATION>	  = configuration name
		$<BOOL:...>		  = '1' if the '...' is true, else '0'
		$<STREQUAL:a,b>		  = '1' if a is STREQUAL b, else '0'
		$<ANGLE-R>		  = A literal '>'. Used to compare strings which contain a '>' for example.
		$<COMMA>		  = A literal ','. Used to compare strings which contain a ',' for example.
		$<SEMICOLON>		  = A literal ';'. Used to prevent list expansion on an argument with ';'.
		$<JOIN:list,...>	  = joins the list with the content of "..."
		$<TARGET_NAME:...>	  = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.	The '...' must be a literal name of a target- it may not contain generator expressions.
		$<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
		$<BUILD_INTERFACE:...>	  = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
		$<C_COMPILER_ID>	  = The CMake-id of the C compiler used.
		$<C_COMPILER_ID:comp>	  = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
		$<CXX_COMPILER_ID>	  = The CMake-id of the CXX compiler used.
		$<CXX_COMPILER_ID:comp>	  = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
		$<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
		$<VERSION_LESS:v1,v2>	  = '1' if v1 is a version less than v2, else '0'.
		$<VERSION_EQUAL:v1,v2>	  = '1' if v1 is the same version as v2, else '0'.
		$<C_COMPILER_VERSION>	  = The version of the C compiler used.
		$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
		$<CXX_COMPILER_VERSION>	  = The version of the CXX compiler used.
		$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
		$<TARGET_FILE:tgt>	  = main file (.exe, .so.1.2, .a)
		$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
		$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

	      where "tgt" is the name of a target.   Target  file  expressions
	      produce a full path, but _DIR and _NAME versions can produce the
	      directory and file name components:

		$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
		$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
		$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

		$<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

	      Note that tgt is not added as a dependency of  the  target  this
	      expression is evaluated on.

		$<TARGET_POLICY:pol>	      = '1' if the policy was NEW when the 'head' target was created, else '0'.	 If the policy was not set, the warning message for the policy will be emitted.	 This generator expression only works for a subset of policies.
		$<INSTALL_PREFIX>	  = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

	      Boolean expressions:

		$<AND:?[,?]...>		  = '1' if all '?' are '1', else '0'
		$<OR:?[,?]...>		  = '0' if all '?' are '0', else '1'
		$<NOT:?>		  = '0' if '?' is '1', else '1'

	      where '?' is always either '0' or '1'.

	      Expressions with an implicit 'this' target:

		$<TARGET_PROPERTY:prop>	  = The value of the property prop on the target on which the generator expression is evaluated.

       DEBUG_POSTFIX
	      See target property <CONFIG>_POSTFIX.

	      This  property  is  a  special  case  of	the more-general <CON‐
	      FIG>_POSTFIX property for the DEBUG configuration.

       DEFINE_SYMBOL
	      Define a symbol when compiling this target's sources.

	      DEFINE_SYMBOL sets the name of the preprocessor  symbol  defined
	      when compiling sources in a shared library. If not set here then
	      it is set to target_EXPORTS by default (with some	 substitutions
	      if  the  target is not a valid C identifier). This is useful for
	      headers to know whether they  are	 being	included  from	inside
	      their  library  or outside to properly setup dllexport/dllimport
	      decorations.

       ENABLE_EXPORTS
	      Specify whether an executable exports symbols for loadable  mod‐
	      ules.

	      Normally an executable does not export any symbols because it is
	      the final program.  It is possible for an executable  to	export
	      symbols  to  be used by loadable modules.	 When this property is
	      set to true CMake will allow other targets to "link" to the exe‐
	      cutable  with  the  TARGET_LINK_LIBRARIES command.  On all plat‐
	      forms a target-level dependency on the executable is created for
	      targets  that  link  to it.  For DLL platforms an import library
	      will be created for the exported symbols and then used for link‐
	      ing.   All  Windows-based systems including Cygwin are DLL plat‐
	      forms.  For non-DLL platforms that require  all  symbols	to  be
	      resolved	at link time, such as Mac OS X, the module will "link"
	      to the executable using a flag like "-bundle_loader".  For other
	      non-DLL  platforms  the  link  rule  is simply ignored since the
	      dynamic loader will automatically bind symbols when  the	module
	      is loaded.

       EXCLUDE_FROM_ALL
	      Exclude the target from the all target.

	      A	 property on a target that indicates if the target is excluded
	      from the default build target. If it is not, then with  a	 Make‐
	      file for example typing make will cause this target to be built.
	      The same concept applies to the default build of	other  genera‐
	      tors.  Installing a target with EXCLUDE_FROM_ALL set to true has
	      undefined behavior.

       EXCLUDE_FROM_DEFAULT_BUILD
	      Exclude target from "Build Solution".

	      This property is only used by Visual  Studio  generators	7  and
	      above.  When  set to TRUE, the target will not be built when you
	      press "Build Solution".

       EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>
	      Per-configuration version of target exclusion from "Build	 Solu‐
	      tion".

	      This     is     the     configuration-specific	 version    of
	      EXCLUDE_FROM_DEFAULT_BUILD.	 If	   the	       generic
	      EXCLUDE_FROM_DEFAULT_BUILD    is	 also	set   on   a   target,
	      EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG> takes precedence in configu‐
	      rations for which it has a value.

       EXPORT_NAME
	      Exported name for target files.

	      This  sets  the  name  for the IMPORTED target generated when it
	      this target is is exported.  If not set, the logical target name
	      is used by default.

       EchoString
	      A message to be displayed when the target is built.

	      A message to display on some generators (such as makefiles) when
	      the target is built.

       FOLDER Set the folder name. Use to organize targets in an IDE.

	      Targets with no FOLDER property will appear as top  level	 enti‐
	      ties  in	IDEs  like Visual Studio. Targets with the same FOLDER
	      property value will appear next to each other  in	 a  folder  of
	      that   name.   To	 nest  folders,	 use  FOLDER  values  such  as
	      'GUI/Dialogs' with '/' characters separating folder levels.

       FRAMEWORK
	      This target is a framework on the Mac.

	      If a shared library target has this property set to true it will
	      be  built as a framework when built on the mac. It will have the
	      directory structure required for a framework and will  be	 suit‐
	      able to be used with the -framework option

       Fortran_FORMAT
	      Set to FIXED or FREE to indicate the Fortran source layout.

	      This  property tells CMake whether the Fortran source files in a
	      target use fixed-format or free-format.	CMake  will  pass  the
	      corresponding  format flag to the compiler.  Use the source-spe‐
	      cific Fortran_FORMAT property to change the format of a specific
	      source file.  If the variable CMAKE_Fortran_FORMAT is set when a
	      target is created its value is used to initialize this property.

       Fortran_MODULE_DIRECTORY
	      Specify output directory for Fortran  modules  provided  by  the
	      target.

	      If the target contains Fortran source files that provide modules
	      and the compiler supports a module output directory this	speci‐
	      fies  the	 directory  in which the modules will be placed.  When
	      this property is not set the modules will be placed in the build
	      directory	 corresponding	to  the target's source directory.  If
	      the variable CMAKE_Fortran_MODULE_DIRECTORY is set when a target
	      is created its value is used to initialize this property.

	      Note  that  some	compilers will automatically search the module
	      output directory for modules USEd during compilation but	others
	      will  not.   If  your sources USE modules their location must be
	      specified by INCLUDE_DIRECTORIES regardless of this property.

       GENERATOR_FILE_NAME
	      Generator's file for this target.

	      An internal property used by some generators to record the  name
	      of  the  project	or  dsp file associated with this target. Note
	      that at configure time, this property is only  set  for  targets
	      created by include_external_msproject().

       GNUtoMS
	      Convert GNU import library (.dll.a) to MS format (.lib).

	      When linking a shared library or executable that exports symbols
	      using GNU tools  on  Windows  (MinGW/MSYS)  with	Visual	Studio
	      installed	 convert  the  import  library (.dll.a) from GNU to MS
	      format (.lib).  Both  import  libraries  will  be	 installed  by
	      install(TARGETS) and exported by install(EXPORT) and export() to
	      be linked by applications	 with  either  GNU-  or	 MS-compatible
	      tools.

	      If  the  variable	 CMAKE_GNUtoMS is set when a target is created
	      its value is used to initialize  this  property.	 The  variable
	      must  be	set prior to the first command that enables a language
	      such as project()	 or  enable_language().	  CMake	 provides  the
	      variable as an option to the user automatically when configuring
	      on Windows with GNU tools.

       HAS_CXX
	      Link the target using the C++ linker tool (obsolete).

	      This is equivalent to setting the	 LINKER_LANGUAGE  property  to
	      CXX.  See that property's documentation for details.

       IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
	      Specify #include line transforms for dependencies in a target.

	      This  property  specifies rules to transform macro-like #include
	      lines during implicit dependency scanning of C  and  C++	source
	      files.   The list of rules must be semicolon-separated with each
	      entry of the form "A_MACRO(%)=value-with-%" (the % must be  lit‐
	      eral).   During  dependency scanning occurrences of A_MACRO(...)
	      on #include lines will be replaced by the value given  with  the
	      macro argument substituted for '%'.  For example, the entry

		MYDIR(%)=<mydir/%>

	      will convert lines of the form

		#include MYDIR(myheader.h)

	      to

		#include <mydir/myheader.h>

	      allowing the dependency to be followed.

	      This  property  applies  to sources in the target on which it is
	      set.

       IMPORTED
	      Read-only indication of whether a target is IMPORTED.

	      The boolean value of this property is true for  targets  created
	      with  the	 IMPORTED option to add_executable or add_library.  It
	      is false for targets built within the project.

       IMPORTED_CONFIGURATIONS
	      Configurations provided for an IMPORTED target.

	      Set this to the list of configuration  names  available  for  an
	      IMPORTED target.	The names correspond to configurations defined
	      in the project from  which  the  target  is  imported.   If  the
	      importing	 project  uses	a  different set of configurations the
	      names may be mapped using the MAP_IMPORTED_CONFIG_<CONFIG> prop‐
	      erty.  Ignored for non-imported targets.

       IMPORTED_IMPLIB
	      Full path to the import library for an IMPORTED target.

	      Set  this	 to  the location of the ".lib" part of a windows DLL.
	      Ignored for non-imported targets.

       IMPORTED_IMPLIB_<CONFIG>
	      <CONFIG>-specific version of IMPORTED_IMPLIB property.

	      Configuration names correspond to those provided by the  project
	      from which the target is imported.

       IMPORTED_LINK_DEPENDENT_LIBRARIES
	      Dependent shared libraries of an imported shared library.

	      Shared libraries may be linked to other shared libraries as part
	      of their implementation.	On some platforms the linker  searches
	      for the dependent libraries of shared libraries they are includ‐
	      ing in the link.	Set this property to  the  list	 of  dependent
	      shared  libraries	 of  an	 imported library.  The list should be
	      disjoint from the list of	 interface  libraries  in  the	INTER‐
	      FACE_LINK_LIBRARIES  property.  On platforms requiring dependent
	      shared libraries to be found at link time CMake uses  this  list
	      to  add  appropriate  files  or  paths to the link command line.
	      Ignored for non-imported targets.

       IMPORTED_LINK_DEPENDENT_LIBRARIES_<CONFIG>
	      <CONFIG>-specific version of IMPORTED_LINK_DEPENDENT_LIBRARIES.

	      Configuration names correspond to those provided by the  project
	      from  which  the target is imported.  If set, this property com‐
	      pletely overrides the generic property for the named  configura‐
	      tion.

       IMPORTED_LINK_INTERFACE_LANGUAGES
	      Languages compiled into an IMPORTED static library.

	      Set  this	 to  the list of languages of source files compiled to
	      produce a STATIC IMPORTED library (such as "C" or "CXX").	 CMake
	      accounts for these languages when computing how to link a target
	      to the imported library.	For example, when a C executable links
	      to  an  imported C++ static library CMake chooses the C++ linker
	      to satisfy language runtime dependencies of the static library.

	      This property  is	 ignored  for  targets	that  are  not	STATIC
	      libraries.  This property is ignored for non-imported targets.

       IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
	      <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LANGUAGES.

	      Configuration  names correspond to those provided by the project
	      from which the target is imported.  If set, this	property  com‐
	      pletely  overrides the generic property for the named configura‐
	      tion.

       IMPORTED_LINK_INTERFACE_LIBRARIES
	      Transitive link interface of an IMPORTED target.

	      Set this to the list of libraries whose  interface  is  included
	      when  an	IMPORTED  library  target is linked to another target.
	      The libraries will be included on the link line for the  target.
	      Unlike  the  LINK_INTERFACE_LIBRARIES  property,	this  property
	      applies  to  all	imported  target   types,   including	STATIC
	      libraries.  This property is ignored for non-imported targets.

	      This  property  is  ignored  if  the target also has a non-empty
	      INTERFACE_LINK_LIBRARIES property.

	      This  property  is  deprecated.	Use   INTERFACE_LINK_LIBRARIES
	      instead.

       IMPORTED_LINK_INTERFACE_LIBRARIES_<CONFIG>
	      <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LIBRARIES.

	      Configuration  names correspond to those provided by the project
	      from which the target is imported.  If set, this	property  com‐
	      pletely  overrides the generic property for the named configura‐
	      tion.

	      This property is ignored if the  target  also  has  a  non-empty
	      INTERFACE_LINK_LIBRARIES property.

	      This   property	is  deprecated.	 Use  INTERFACE_LINK_LIBRARIES
	      instead.

       IMPORTED_LINK_INTERFACE_MULTIPLICITY
	      Repetition count for cycles of IMPORTED static libraries.

	      This is LINK_INTERFACE_MULTIPLICITY for IMPORTED targets.

       IMPORTED_LINK_INTERFACE_MULTIPLICITY_<CONFIG>
	      <CONFIG>-specific version of  IMPORTED_LINK_INTERFACE_MULTIPLIC‐
	      ITY.

	      If  set, this property completely overrides the generic property
	      for the named configuration.

       IMPORTED_LOCATION
	      Full path to the main file on disk for an IMPORTED target.

	      Set this to the location of an IMPORTED  target  file  on	 disk.
	      For  executables	this  is  the location of the executable file.
	      For bundles on OS X this is the location of the executable  file
	      inside  Contents/MacOS under the application bundle folder.  For
	      static libraries and modules this is the location of the library
	      or  module.   For	 shared libraries on non-DLL platforms this is
	      the location of the shared library.  For frameworks on OS X this
	      is  the  location	 of  the  library file symlink just inside the
	      framework folder.	 For DLLs this is the location of  the	".dll"
	      part of the library.  For UNKNOWN libraries this is the location
	      of the file to be linked.	 Ignored for non-imported targets.

	      Projects may skip IMPORTED_LOCATION  if  the  configuration-spe‐
	      cific  property  IMPORTED_LOCATION_<CONFIG>  is set.  To get the
	      location of an imported target read one of the LOCATION or LOCA‐
	      TION_<CONFIG> properties.

       IMPORTED_LOCATION_<CONFIG>
	      <CONFIG>-specific version of IMPORTED_LOCATION property.

	      Configuration  names correspond to those provided by the project
	      from which the target is imported.

       IMPORTED_NO_SONAME
	      Specifies that an IMPORTED shared library target	has  no	 "son‐
	      ame".

	      Set  this	 property  to true for an imported shared library file
	      that has no "soname" field.  CMake  may  adjust  generated  link
	      commands for some platforms to prevent the linker from using the
	      path to the library in place of its missing soname.  Ignored for
	      non-imported targets.

       IMPORTED_NO_SONAME_<CONFIG>
	      <CONFIG>-specific version of IMPORTED_NO_SONAME property.

	      Configuration  names correspond to those provided by the project
	      from which the target is imported.

       IMPORTED_SONAME
	      The "soname" of an IMPORTED target of shared library type.

	      Set this to the "soname" embedded in an imported shared library.
	      This  is	meaningful  only  on platforms supporting the feature.
	      Ignored for non-imported targets.

       IMPORTED_SONAME_<CONFIG>
	      <CONFIG>-specific version of IMPORTED_SONAME property.

	      Configuration names correspond to those provided by the  project
	      from which the target is imported.

       IMPORT_PREFIX
	      What comes before the import library name.

	      Similar  to  the	target	property  PREFIX,  but used for import
	      libraries (typically corresponding to a DLL) instead of  regular
	      libraries.  A  target  property  that can be set to override the
	      prefix (such as "lib") on an import library name.

       IMPORT_SUFFIX
	      What comes after the import library name.

	      Similar to the target  property  SUFFIX,	but  used  for	import
	      libraries	 (typically corresponding to a DLL) instead of regular
	      libraries. A target property that can be	set  to	 override  the
	      suffix (such as ".lib") on an import library name.

       INCLUDE_DIRECTORIES
	      List of preprocessor include file search directories.

	      This  property specifies the list of directories given so far to
	      the include_directories command. This property exists on	direc‐
	      tories  and  targets.  In	 addition to accepting values from the
	      include_directories command, values may be set directly  on  any
	      directory or any target using the set_property command. A target
	      gets its initial value for this property from the value  of  the
	      directory	 property. A directory gets its initial value from its
	      parent directory if it has one. Both directory and target	 prop‐
	      erty  values  are	 adjusted  by calls to the include_directories
	      command.

	      The target property values are used by the generators to set the
	      include  paths  for the compiler.	 See also the include_directo‐
	      ries command.

	      Contents of INCLUDE_DIRECTORIES may use "generator  expressions"
	      with  the	 syntax "$<...>".  Generator expressions are evaluated
	      during build system generation to produce	 information  specific
	      to each build configuration.  Valid expressions are:

		$<0:...>		  = empty string (ignores "...")
		$<1:...>		  = content of "..."
		$<CONFIG:cfg>		  = '1' if config is "cfg", else '0'
		$<CONFIGURATION>	  = configuration name
		$<BOOL:...>		  = '1' if the '...' is true, else '0'
		$<STREQUAL:a,b>		  = '1' if a is STREQUAL b, else '0'
		$<ANGLE-R>		  = A literal '>'. Used to compare strings which contain a '>' for example.
		$<COMMA>		  = A literal ','. Used to compare strings which contain a ',' for example.
		$<SEMICOLON>		  = A literal ';'. Used to prevent list expansion on an argument with ';'.
		$<JOIN:list,...>	  = joins the list with the content of "..."
		$<TARGET_NAME:...>	  = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.	The '...' must be a literal name of a target- it may not contain generator expressions.
		$<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
		$<BUILD_INTERFACE:...>	  = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
		$<C_COMPILER_ID>	  = The CMake-id of the C compiler used.
		$<C_COMPILER_ID:comp>	  = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
		$<CXX_COMPILER_ID>	  = The CMake-id of the CXX compiler used.
		$<CXX_COMPILER_ID:comp>	  = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
		$<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
		$<VERSION_LESS:v1,v2>	  = '1' if v1 is a version less than v2, else '0'.
		$<VERSION_EQUAL:v1,v2>	  = '1' if v1 is the same version as v2, else '0'.

		$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
		$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
		$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

		$<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

	      Note that tgt is not added as a dependency of  the  target  this
	      expression is evaluated on.

		$<TARGET_POLICY:pol>	      = '1' if the policy was NEW when the 'head' target was created, else '0'.	 If the policy was not set, the warning message for the policy will be emitted.	 This generator expression only works for a subset of policies.
		$<INSTALL_PREFIX>	  = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

	      Boolean expressions:

		$<AND:?[,?]...>		  = '1' if all '?' are '1', else '0'
		$<OR:?[,?]...>		  = '0' if all '?' are '0', else '1'
		$<NOT:?>		  = '0' if '?' is '1', else '1'

	      where '?' is always either '0' or '1'.

	      Expressions with an implicit 'this' target:

		$<TARGET_PROPERTY:prop>	  = The value of the property prop on the target on which the generator expression is evaluated.

       INTERPROCEDURAL_OPTIMIZATION
	      Enable interprocedural optimization for a target.

	      If  set  to  true, enables interprocedural optimizations if they
	      are known to be supported by the compiler.

       INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
	      Per-configuration interprocedural optimization for a target.

	      This is a per-configuration version of INTERPROCEDURAL_OPTIMIZA‐
	      TION.   If set, this property overrides the generic property for
	      the named configuration.

       LABELS Specify a list of text labels associated with a target.

	      Target label semantics are currently unspecified.

       LIBRARY_OUTPUT_DIRECTORY
	      Output directory in which to build LIBRARY target files.

	      This property specifies the directory into which library	target
	      files  should  be	 built.	 Multi-configuration  generators  (VS,
	      Xcode) append a per-configuration subdirectory to the  specified
	      directory.   There  are  three kinds of target files that may be
	      built: archive, library, and runtime.   Executables  are	always
	      treated  as runtime targets. Static libraries are always treated
	      as archive targets.  Module  libraries  are  always  treated  as
	      library  targets.	 For  non-DLL  platforms  shared libraries are
	      treated as library targets. For DLL platforms the DLL part of  a
	      shared  library  is  treated  as a runtime target and the corre‐
	      sponding import library is treated as  an	 archive  target.  All
	      Windows-based  systems including Cygwin are DLL platforms.  This
	      property	is  initialized	 by  the   value   of	the   variable
	      CMAKE_LIBRARY_OUTPUT_DIRECTORY  if  it  is  set when a target is
	      created.

       LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
	      Per-configuration output directory for LIBRARY target files.

	      This is a per-configuration version of LIBRARY_OUTPUT_DIRECTORY,
	      but  multi-configuration	generators (VS, Xcode) do NOT append a
	      per-configuration subdirectory to the specified directory.  This
	      property	 is   initialized   by	 the  value  of	 the  variable
	      CMAKE_LIBRARY_OUTPUT_DIRECTORY_<CONFIG> if it is set when a tar‐
	      get is created.

       LIBRARY_OUTPUT_NAME
	      Output name for LIBRARY target files.

	      This  property specifies the base name for library target files.
	      It overrides OUTPUT_NAME	and  OUTPUT_NAME_<CONFIG>  properties.
	      There  are  three	 kinds	of target files that may be built: ar‐
	      chive, library, and runtime.  Executables are always treated  as
	      runtime  targets. Static libraries are always treated as archive
	      targets. Module libraries are always treated as library targets.
	      For  non-DLL  platforms  shared libraries are treated as library
	      targets. For DLL platforms the DLL part of a shared  library  is
	      treated as a runtime target and the corresponding import library
	      is treated as  an	 archive  target.  All	Windows-based  systems
	      including Cygwin are DLL platforms.

       LIBRARY_OUTPUT_NAME_<CONFIG>
	      Per-configuration output name for LIBRARY target files.

	      This  is	the  configuration-specific  version  of  LIBRARY_OUT‐
	      PUT_NAME.

       LINKER_LANGUAGE
	      Specifies language whose compiler will invoke the linker.

	      For executables, shared libraries, and modules,  this  sets  the
	      language	whose compiler is used to link the target (such as "C"
	      or "CXX").  A typical value for an executable is the language of
	      the  source  file	 providing the program entry point (main).  If
	      not set, the language with the highest linker  preference	 value
	      is  the default.	See documentation of CMAKE_<LANG>_LINKER_PREF‐
	      ERENCE variables.

	      If this property is not set by the user, it will	be  calculated
	      at generate-time by CMake.

       LINK_DEPENDS
	      Additional files on which a target binary depends for linking.

	      Specifies	 a  semicolon-separated list of full-paths to files on
	      which the link rule for this target depends.  The target	binary
	      will be linked if any of the named files is newer than it.

	      This  property  is  ignored  by  non-Makefile generators.	 It is
	      intended to specify dependencies on "linker scripts" for	custom
	      Makefile link rules.

       LINK_DEPENDS_NO_SHARED
	      Do not depend on linked shared library files.

	      Set  this	 property  to true to tell CMake generators not to add
	      file-level dependencies on the shared library  files  linked  by
	      this  target.   Modification to the shared libraries will not be
	      sufficient to re-link this target.  Logical target-level	depen‐
	      dencies will not be affected so the linked shared libraries will
	      still be brought up to date before this target is built.

	      This property is	initialized  by	 the  value  of	 the  variable
	      CMAKE_LINK_DEPENDS_NO_SHARED  if it is set when a target is cre‐
	      ated.

       LINK_FLAGS
	      Additional flags to use when linking this target.

	      The LINK_FLAGS property can be used to add extra	flags  to  the
	      link  step of a target. LINK_FLAGS_<CONFIG> will add to the con‐
	      figuration <CONFIG>, for example,	 DEBUG,	 RELEASE,  MINSIZEREL,
	      RELWITHDEBINFO.

       LINK_FLAGS_<CONFIG>
	      Per-configuration linker flags for a target.

	      This is the configuration-specific version of LINK_FLAGS.

       LINK_INTERFACE_LIBRARIES
	      List  public  interface  libraries  for a shared library or exe‐
	      cutable.

	      By default linking to a shared library target transitively links
	      to  targets  with	 which	the library itself was linked.	For an
	      executable with exports (see  the	 ENABLE_EXPORTS	 property)  no
	      default  transitive  link	 dependencies are used.	 This property
	      replaces	the  default  transitive  link	dependencies  with  an
	      explicit	list.	When  the target is linked into another target
	      the libraries  listed  (and  recursively	their  link  interface
	      libraries)  will	be  provided to the other target also.	If the
	      list is empty then  no  transitive  link	dependencies  will  be
	      incorporated when this target is linked into another target even
	      if the default set is non-empty.	This property  is  initialized
	      by  the  value of the variable CMAKE_LINK_INTERFACE_LIBRARIES if
	      it is set when a target is created.  This	 property  is  ignored
	      for STATIC libraries.

	      This property is overriden by the INTERFACE_LINK_LIBRARIES prop‐
	      erty if policy CMP0022 is NEW.

	      This  property  is  deprecated.	Use   INTERFACE_LINK_LIBRARIES
	      instead.

       LINK_INTERFACE_LIBRARIES_<CONFIG>
	      Per-configuration	 list of public interface libraries for a tar‐
	      get.

	      This  is	the  configuration-specific  version  of   LINK_INTER‐
	      FACE_LIBRARIES.	If set, this property completely overrides the
	      generic property for the named configuration.

	      This property is overriden by the INTERFACE_LINK_LIBRARIES prop‐
	      erty if policy CMP0022 is NEW.

	      This   property	is  deprecated.	 Use  INTERFACE_LINK_LIBRARIES
	      instead.

       LINK_INTERFACE_MULTIPLICITY
	      Repetition count for STATIC libraries with cyclic dependencies.

	      When linking to a STATIC library target with cyclic dependencies
	      the  linker may need to scan more than once through the archives
	      in the strongly connected component  of  the  dependency	graph.
	      CMake  by	 default  constructs  the link line so that the linker
	      will scan through the component at least twice.	This  property
	      specifies	 the  minimum number of scans if it is larger than the
	      default.	CMake uses the largest value specified by  any	target
	      in a component.

       LINK_INTERFACE_MULTIPLICITY_<CONFIG>
	      Per-configuration	  repetition   count   for  cycles  of	STATIC
	      libraries.

	      This  is	the  configuration-specific  version  of   LINK_INTER‐
	      FACE_MULTIPLICITY.   If  set, this property completely overrides
	      the generic property for the named configuration.

       LINK_LIBRARIES
	      List of direct link dependencies.

	      This property specifies the list of libraries or	targets	 which
	      will  be	used for linking. In addition to accepting values from
	      the target_link_libraries command, values may be set directly on
	      any target using the set_property command.

	      The target property values are used by the generators to set the
	      link  libraries  for  the	  compiler.    See   also   the	  tar‐
	      get_link_libraries command.

	      Contents	of LINK_LIBRARIES may use "generator expressions" with
	      the syntax "$<...>".  Generator expressions are evaluated during
	      build  system generation to produce information specific to each
	      build configuration.  Valid expressions are:

		$<0:...>		  = empty string (ignores "...")
		$<1:...>		  = content of "..."
		$<CONFIG:cfg>		  = '1' if config is "cfg", else '0'
		$<CONFIGURATION>	  = configuration name
		$<BOOL:...>		  = '1' if the '...' is true, else '0'
		$<STREQUAL:a,b>		  = '1' if a is STREQUAL b, else '0'
		$<ANGLE-R>		  = A literal '>'. Used to compare strings which contain a '>' for example.
		$<COMMA>		  = A literal ','. Used to compare strings which contain a ',' for example.
		$<SEMICOLON>		  = A literal ';'. Used to prevent list expansion on an argument with ';'.
		$<JOIN:list,...>	  = joins the list with the content of "..."
		$<TARGET_NAME:...>	  = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.	The '...' must be a literal name of a target- it may not contain generator expressions.
		$<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
		$<BUILD_INTERFACE:...>	  = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
		$<C_COMPILER_ID>	  = The CMake-id of the C compiler used.
		$<C_COMPILER_ID:comp>	  = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
		$<CXX_COMPILER_ID>	  = The CMake-id of the CXX compiler used.
		$<CXX_COMPILER_ID:comp>	  = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
		$<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
		$<VERSION_LESS:v1,v2>	  = '1' if v1 is a version less than v2, else '0'.
		$<VERSION_EQUAL:v1,v2>	  = '1' if v1 is the same version as v2, else '0'.
		$<C_COMPILER_VERSION>	  = The version of the C compiler used.
		$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
		$<CXX_COMPILER_VERSION>	  = The version of the CXX compiler used.
		$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
		$<TARGET_FILE:tgt>	  = main file (.exe, .so.1.2, .a)
		$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
		$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

	      where "tgt" is the name of a target.   Target  file  expressions
	      produce a full path, but _DIR and _NAME versions can produce the
	      directory and file name components:

		$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
		$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
		$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

		$<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

	      Note that tgt is not added as a dependency of  the  target  this
	      expression is evaluated on.

		$<TARGET_POLICY:pol>	      = '1' if the policy was NEW when the 'head' target was created, else '0'.	 If the policy was not set, the warning message for the policy will be emitted.	 This generator expression only works for a subset of policies.
		$<INSTALL_PREFIX>	  = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

	      Boolean expressions:

		$<AND:?[,?]...>		  = '1' if all '?' are '1', else '0'
		$<OR:?[,?]...>		  = '0' if all '?' are '0', else '1'
		$<NOT:?>		  = '0' if '?' is '1', else '1'

	      where '?' is always either '0' or '1'.

	      Expressions with an implicit 'this' target:

		$<TARGET_PROPERTY:prop>	  = The value of the property prop on the target on which the generator expression is evaluated.

       LINK_SEARCH_END_STATIC
	      End a link line such that static system libraries are used.

	      Some  linkers support switches such as -Bstatic and -Bdynamic to
	      determine whether to use static or shared	 libraries  for	 -lXXX
	      options.	 CMake	uses  these  options  to set the link type for
	      libraries whose full paths are not known or (in some cases)  are
	      in implicit link directories for the platform.  By default CMake
	      adds an option at the end of the library list (if necessary)  to
	      set  the	linker	search	type  back to its starting type.  This
	      property switches the  final  linker  search  type  to  -Bstatic
	      regardless      of     how     it	    started.	  See	  also
	      LINK_SEARCH_START_STATIC.

       LINK_SEARCH_START_STATIC
	      Assume the linker looks for static libraries by default.

	      Some linkers support switches such as -Bstatic and -Bdynamic  to
	      determine	 whether  to  use static or shared libraries for -lXXX
	      options.	CMake uses these options to  set  the  link  type  for
	      libraries	 whose full paths are not known or (in some cases) are
	      in implicit link directories for the platform.  By  default  the
	      linker  search  type is assumed to be -Bdynamic at the beginning
	      of the library list.  This property switches the	assumption  to
	      -Bstatic.	  It  is  intended  for use when linking an executable
	      statically  (e.g.	 with  the  GNU	 -static  option).   See  also
	      LINK_SEARCH_END_STATIC.

       LOCATION
	      Read-only location of a target on disk.

	      For  an  imported	 target,  this	read-only property returns the
	      value of the LOCATION_<CONFIG> property for an unspecified  con‐
	      figuration <CONFIG> provided by the target.

	      For a non-imported target, this property is provided for compat‐
	      ibility with CMake 2.4 and below.	 It was meant to get the loca‐
	      tion  of	an executable target's output file for use in add_cus‐
	      tom_command.  The path may contain a build-system-specific  por‐
	      tion  that is replaced at build time with the configuration get‐
	      ting built (such as "$(ConfigurationName)" in VS). In CMake  2.6
	      and  above  add_custom_command automatically recognizes a target
	      name in its COMMAND and DEPENDS options and computes the	target
	      location.	  In  CMake  2.8.4 and above add_custom_command recog‐
	      nizes generator expressions to refer to  target  locations  any‐
	      where in the command.  Therefore this property is not needed for
	      creating custom commands.

	      Do not set properties that affect the location of a target after
	      reading  this  property.	 These	include properties whose names
	      match  "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CON‐
	      FIG>)?",	 "(IMPLIB_)?(PREFIX|SUFFIX)",	or  "LINKER_LANGUAGE".
	      Failure to follow this rule is  not  diagnosed  and  leaves  the
	      location of the target undefined.

       LOCATION_<CONFIG>
	      Read-only property providing a target location on disk.

	      A	 read-only  property that indicates where a target's main file
	      is located on disk for the configuration <CONFIG>.  The property
	      is defined only for library and executable targets.  An imported
	      target may provide a set of configurations different  from  that
	      of  the  importing  project.   By	 default  CMake	 looks	for an
	      exact-match but otherwise uses an arbitrary available configura‐
	      tion.   Use  the	MAP_IMPORTED_CONFIG_<CONFIG>  property	to map
	      imported configurations explicitly.

	      Do not set properties that affect the location of a target after
	      reading  this  property.	 These	include properties whose names
	      match  "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CON‐
	      FIG>)?",	 "(IMPLIB_)?(PREFIX|SUFFIX)",	or  "LINKER_LANGUAGE".
	      Failure to follow this rule is  not  diagnosed  and  leaves  the
	      location of the target undefined.

       MACOSX_BUNDLE
	      Build an executable as an application bundle on Mac OS X.

	      When  this  property is set to true the executable when built on
	      Mac OS X will be created as an application bundle.   This	 makes
	      it  a  GUI executable that can be launched from the Finder.  See
	      the MACOSX_BUNDLE_INFO_PLIST  target  property  for  information
	      about  creation  of the Info.plist file for the application bun‐
	      dle.  This property is initialized by the value of the  variable
	      CMAKE_MACOSX_BUNDLE if it is set when a target is created.

       MACOSX_BUNDLE_INFO_PLIST
	      Specify a custom Info.plist template for a Mac OS X App Bundle.

	      An executable target with MACOSX_BUNDLE enabled will be built as
	      an application bundle on Mac OS X.  By  default  its  Info.plist
	      file  is	created by configuring a template called MacOSXBundle‐
	      Info.plist.in located in the CMAKE_MODULE_PATH.	This  property
	      specifies	 an alternative template file name which may be a full
	      path.

	      The following target properties may be set to specify content to
	      be configured into the file:

		MACOSX_BUNDLE_INFO_STRING
		MACOSX_BUNDLE_ICON_FILE
		MACOSX_BUNDLE_GUI_IDENTIFIER
		MACOSX_BUNDLE_LONG_VERSION_STRING
		MACOSX_BUNDLE_BUNDLE_NAME
		MACOSX_BUNDLE_SHORT_VERSION_STRING
		MACOSX_BUNDLE_BUNDLE_VERSION
		MACOSX_BUNDLE_COPYRIGHT

	      CMake  variables	of the same name may be set to affect all tar‐
	      gets in a directory that do not have each specific property set.
	      If  a  custom Info.plist is specified by this property it may of
	      course hard-code all the settings instead of  using  the	target
	      properties.

       MACOSX_FRAMEWORK_INFO_PLIST
	      Specify a custom Info.plist template for a Mac OS X Framework.

	      A	 library  target  with	FRAMEWORK  enabled  will be built as a
	      framework on Mac OS X.  By default its Info.plist file  is  cre‐
	      ated   by	  configuring	a   template  called  MacOSXFramework‐
	      Info.plist.in located in the CMAKE_MODULE_PATH.	This  property
	      specifies	 an alternative template file name which may be a full
	      path.

	      The following target properties may be set to specify content to
	      be configured into the file:

		MACOSX_FRAMEWORK_ICON_FILE
		MACOSX_FRAMEWORK_IDENTIFIER
		MACOSX_FRAMEWORK_SHORT_VERSION_STRING
		MACOSX_FRAMEWORK_BUNDLE_VERSION

	      CMake  variables	of the same name may be set to affect all tar‐
	      gets in a directory that do not have each specific property set.
	      If  a  custom Info.plist is specified by this property it may of
	      course hard-code all the settings instead of  using  the	target
	      properties.

       MACOSX_RPATH
	      Whether to use rpaths on Mac OS X.

	      When  this  property  is	set  to true, the directory portion of
	      the"install_name" field of  shared  libraries  will  default  to
	      "@rpath".Runtime	paths  will also be embedded in binaries using
	      this target.This property is initialized by  the	value  of  the
	      variable	CMAKE_MACOSX_RPATH  if it is set when a target is cre‐
	      ated.

       MAP_IMPORTED_CONFIG_<CONFIG>
	      Map from project configuration to IMPORTED  target's  configura‐
	      tion.

	      Set  this	 to  the  list of configurations of an imported target
	      that may be used for the current project's  <CONFIG>  configura‐
	      tion.  Targets imported from another project may not provide the
	      same  set	 of  configuration  names  available  in  the  current
	      project.	 Setting  this property tells CMake what imported con‐
	      figurations are suitable for use when building the <CONFIG> con‐
	      figuration.   The	 first	configuration  in the list found to be
	      provided by the imported target is selected.  If	this  property
	      is  set  and  no matching configurations are available, then the
	      imported target is considered to be not found.  This property is
	      ignored for non-imported targets.

       NAME   Logical name for the target.

	      Read-only logical name for the target as used by CMake.

       NO_SONAME
	      Whether to set "soname" when linking a shared library or module.

	      Enable  this  boolean  property if a generated shared library or
	      module should not have "soname" set. Default is to set  "soname"
	      on all shared libraries and modules as long as the platform sup‐
	      ports it. Generally, use this property  only  for	 leaf  private
	      libraries	 or  plugins. If you use it on normal shared libraries
	      which other targets link against, on  some  platforms  a	linker
	      will  insert  a  full  path to the library (as specified at link
	      time) into the dynamic section of the dependent  binary.	There‐
	      fore,  once  installed,  dynamic	loader	may eventually fail to
	      locate the library for the binary.

       OSX_ARCHITECTURES
	      Target specific architectures for OS X.

	      The OSX_ARCHITECTURES property sets the target binary  architec‐
	      ture  for	 targets on OS X.  This property is initialized by the
	      value of the variable CMAKE_OSX_ARCHITECTURES if it is set  when
	      a	 target is created.  Use OSX_ARCHITECTURES_<CONFIG> to set the
	      binary architectures on a per-configuration basis.  <CONFIG>  is
	      an upper-case name (ex: "OSX_ARCHITECTURES_DEBUG").

       OSX_ARCHITECTURES_<CONFIG>
	      Per-configuration OS X binary architectures for a target.

	      This   property	is   the   configuration-specific  version  of
	      OSX_ARCHITECTURES.

       OUTPUT_NAME
	      Output name for target files.

	      This sets the base name for output files	created	 for  an  exe‐
	      cutable  or library target.  If not set, the logical target name
	      is used by default.

       OUTPUT_NAME_<CONFIG>
	      Per-configuration target file base name.

	      This is the configuration-specific version of OUTPUT_NAME.

       PDB_NAME
	      Output name for MS debug symbols .pdb file from linker.

	      Set the base name for debug symbols file	created	 for  an  exe‐
	      cutable  or shared library target.  If not set, the logical tar‐
	      get name is used by default.

	      This property is not implemented by the Visual Studio 6  genera‐
	      tor.

       PDB_NAME_<CONFIG>
	      Per-configuration name for MS debug symbols .pdb file.

	      This is the configuration-specific version of PDB_NAME.

	      This  property is not implemented by the Visual Studio 6 genera‐
	      tor.

       PDB_OUTPUT_DIRECTORY
	      Output directory for MS debug symbols .pdb file from linker.

	      This property specifies the directory into which	the  MS	 debug
	      symbols will be placed by the linker.  This property is initial‐
	      ized by the value of the variable CMAKE_PDB_OUTPUT_DIRECTORY  if
	      it is set when a target is created.

	      This  property is not implemented by the Visual Studio 6 genera‐
	      tor.

       PDB_OUTPUT_DIRECTORY_<CONFIG>
	      Per-configuration output directory for  MS  debug	 symbols  .pdb
	      files.

	      This is a per-configuration version of PDB_OUTPUT_DIRECTORY, but
	      multi-configuration generators  (VS,  Xcode)  do	NOT  append  a
	      per-configuration	 subdirectory to the specified directory. This
	      property	is  initialized	 by  the   value   of	the   variable
	      CMAKE_PDB_OUTPUT_DIRECTORY_<CONFIG>  if  it is set when a target
	      is created.

	      This property is not implemented by the Visual Studio 6  genera‐
	      tor.

       POSITION_INDEPENDENT_CODE
	      Whether to create a position-independent target

	      The  POSITION_INDEPENDENT_CODE property determines whether posi‐
	      tion independent executables or shared libraries	will  be  cre‐
	      ated.   This  property  is true by default for SHARED and MODULE
	      library targets and false otherwise.  This property is  initial‐
	      ized  by	the  value  of	the  variable  CMAKE_POSITION_INDEPEN‐
	      DENT_CODE if it is set when a target is created.

       POST_INSTALL_SCRIPT
	      Deprecated install support.

	      The PRE_INSTALL_SCRIPT and  POST_INSTALL_SCRIPT  properties  are
	      the  old	way  to	 specify CMake scripts to run before and after
	      installing  a  target.   They  are  used	only  when   the   old
	      INSTALL_TARGETS  command is used to install the target.  Use the
	      INSTALL command instead.

       PREFIX What comes before the library name.

	      A target property that can be set to override the	 prefix	 (such
	      as "lib") on a library name.

       PRE_INSTALL_SCRIPT
	      Deprecated install support.

	      The  PRE_INSTALL_SCRIPT  and  POST_INSTALL_SCRIPT properties are
	      the old way to specify CMake scripts to  run  before  and	 after
	      installing   a   target.	 They  are  used  only	when  the  old
	      INSTALL_TARGETS command is used to install the target.  Use  the
	      INSTALL command instead.

       PRIVATE_HEADER
	      Specify  private header files in a FRAMEWORK shared library tar‐
	      get.

	      Shared library targets marked with the FRAMEWORK property gener‐
	      ate  frameworks  on  OS  X  and normal shared libraries on other
	      platforms.  This property may be set to a list of	 header	 files
	      to  be  placed in the PrivateHeaders directory inside the frame‐
	      work folder.   On	 non-Apple  platforms  these  headers  may  be
	      installed	 using	the  PRIVATE_HEADER option to the install(TAR‐
	      GETS) command.

       PROJECT_LABEL
	      Change the name of a target in an IDE.

	      Can be used to change the name of the target in an IDE like Vis‐
	      ual Studio.

       PUBLIC_HEADER
	      Specify  public  header files in a FRAMEWORK shared library tar‐
	      get.

	      Shared library targets marked with the FRAMEWORK property gener‐
	      ate  frameworks  on  OS  X  and normal shared libraries on other
	      platforms.  This property may be set to a list of	 header	 files
	      to  be  placed  in  the  Headers	directory inside the framework
	      folder.  On non-Apple platforms these headers may	 be  installed
	      using the PUBLIC_HEADER option to the install(TARGETS) command.

       RESOURCE
	      Specify resource files in a FRAMEWORK shared library target.

	      Shared library targets marked with the FRAMEWORK property gener‐
	      ate frameworks on OS X and  normal  shared  libraries  on	 other
	      platforms.   This	 property  may be set to a list of files to be
	      placed in the Resources directory inside the  framework  folder.
	      On  non-Apple  platforms	these files may be installed using the
	      RESOURCE option to the install(TARGETS) command.

       RULE_LAUNCH_COMPILE
	      Specify a launcher for compile rules.

	      See the global property of the  same  name  for  details.	  This
	      overrides the global and directory property for a target.

       RULE_LAUNCH_CUSTOM
	      Specify a launcher for custom rules.

	      See  the	global	property  of  the same name for details.  This
	      overrides the global and directory property for a target.

       RULE_LAUNCH_LINK
	      Specify a launcher for link rules.

	      See the global property of the  same  name  for  details.	  This
	      overrides the global and directory property for a target.

       RUNTIME_OUTPUT_DIRECTORY
	      Output directory in which to build RUNTIME target files.

	      This  property specifies the directory into which runtime target
	      files  should  be	 built.	 Multi-configuration  generators  (VS,
	      Xcode)  append a per-configuration subdirectory to the specified
	      directory.  There are three kinds of target files	 that  may  be
	      built:  archive,	library,  and runtime.	Executables are always
	      treated as runtime targets. Static libraries are always  treated
	      as  archive  targets.  Module  libraries	are  always treated as
	      library targets. For  non-DLL  platforms	shared	libraries  are
	      treated  as library targets. For DLL platforms the DLL part of a
	      shared library is treated as a runtime  target  and  the	corre‐
	      sponding	import	library	 is  treated as an archive target. All
	      Windows-based systems including Cygwin are DLL platforms.	  This
	      property	is initialized by the value of the variable CMAKE_RUN‐
	      TIME_OUTPUT_DIRECTORY if it is set when a target is created.

       RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
	      Per-configuration output directory for RUNTIME target files.

	      This is a per-configuration version of RUNTIME_OUTPUT_DIRECTORY,
	      but  multi-configuration	generators (VS, Xcode) do NOT append a
	      per-configuration subdirectory to the specified directory.  This
	      property	is initialized by the value of the variable CMAKE_RUN‐
	      TIME_OUTPUT_DIRECTORY_<CONFIG> if it is set  when	 a  target  is
	      created.

       RUNTIME_OUTPUT_NAME
	      Output name for RUNTIME target files.

	      This  property specifies the base name for runtime target files.
	      It overrides OUTPUT_NAME	and  OUTPUT_NAME_<CONFIG>  properties.
	      There  are  three	 kinds	of target files that may be built: ar‐
	      chive, library, and runtime.  Executables are always treated  as
	      runtime  targets. Static libraries are always treated as archive
	      targets. Module libraries are always treated as library targets.
	      For  non-DLL  platforms  shared libraries are treated as library
	      targets. For DLL platforms the DLL part of a shared  library  is
	      treated as a runtime target and the corresponding import library
	      is treated as  an	 archive  target.  All	Windows-based  systems
	      including Cygwin are DLL platforms.

       RUNTIME_OUTPUT_NAME_<CONFIG>
	      Per-configuration output name for RUNTIME target files.

	      This  is	the  configuration-specific  version  of  RUNTIME_OUT‐
	      PUT_NAME.

       SKIP_BUILD_RPATH
	      Should rpaths be used for the build tree.

	      SKIP_BUILD_RPATH is a boolean specifying whether to  skip	 auto‐
	      matic generation of an rpath allowing the target to run from the
	      build tree.  This property is initialized by the	value  of  the
	      variable	CMAKE_SKIP_BUILD_RPATH	if  it is set when a target is
	      created.

       SOURCES
	      Source names specified for a target.

	      Read-only list of sources specified for  a  target.   The	 names
	      returned	are suitable for passing to the set_source_files_prop‐
	      erties command.

       SOVERSION
	      What version number is this target.

	      For shared libraries VERSION and SOVERSION can be used to	 spec‐
	      ify  the build version and API version respectively. When build‐
	      ing or installing appropriate symlinks are created if the	 plat‐
	      form supports symlinks and the linker supports so-names. If only
	      one of both is specified the missing is assumed to have the same
	      version  number.	SOVERSION  is ignored if NO_SONAME property is
	      set. For shared libraries and executables on Windows the VERSION
	      attribute	 is  parsed to extract a "major.minor" version number.
	      These numbers are used as the image version of the binary.

       STATIC_LIBRARY_FLAGS
	      Extra flags to use when linking static libraries.

	      Extra flags to use when linking a static library.

       STATIC_LIBRARY_FLAGS_<CONFIG>
	      Per-configuration flags for creating a static library.

	      This    is     the     configuration-specific	version	    of
	      STATIC_LIBRARY_FLAGS.

       SUFFIX What comes after the target name.

	      A	 target	 property that can be set to override the suffix (such
	      as ".so" or ".exe") on the name of a  library,  module  or  exe‐
	      cutable.

       TYPE   The type of the target.

	      This  read-only  property	 can  be  used to test the type of the
	      given target. It will be one of STATIC_LIBRARY,  MODULE_LIBRARY,
	      SHARED_LIBRARY, EXECUTABLE or one of the internal target types.

       VERSION
	      What version number is this target.

	      For  shared libraries VERSION and SOVERSION can be used to spec‐
	      ify the build version and API version respectively. When	build‐
	      ing  or installing appropriate symlinks are created if the plat‐
	      form supports symlinks and the linker supports so-names. If only
	      one of both is specified the missing is assumed to have the same
	      version number. For executables VERSION can be used  to  specify
	      the  build version. When building or installing appropriate sym‐
	      links are created if the platform supports symlinks. For	shared
	      libraries	 and  executables  on Windows the VERSION attribute is
	      parsed to extract a "major.minor" version number. These  numbers
	      are used as the image version of the binary.

       VISIBILITY_INLINES_HIDDEN
	      Whether  to  add	a compile flag to hide symbols of inline func‐
	      tions

	      The VISIBILITY_INLINES_HIDDEN property determines whether a flag
	      for  hiding  symbols for inline functions. the value passed used
	      in a visibility related compile option, such  as	-fvisibility=.
	      This  property  only has an affect for libraries and executables
	      with exports.  This property is initialized by the value of  the
	      variable	CMAKE_VISIBILITY_INLINES_HIDDEN	 if  it	 is set when a
	      target is created.

       VS_DOTNET_REFERENCES
	      Visual Studio managed project .NET references

	      Adds one or more semicolon-delimited .NET references to a gener‐
	      ated  Visual  Studio  project.  For example, "System;System.Win‐
	      dows.Forms".

       VS_DOTNET_TARGET_FRAMEWORK_VERSION
	      Specify the .NET target framework version.

	      For example, "v4.5".

       VS_GLOBAL_<variable>
	      Visual Studio project-specific global variable.

	      Tell  the	 Visual	 Studio	 generator  to set the global variable
	      '<variable>' to a given value in	the  generated	Visual	Studio
	      project.	Ignored on other generators. Qt integration works bet‐
	      ter if VS_GLOBAL_QtVersion is set to the	version	 FindQt4.cmake
	      found. For example, "4.7.3"

       VS_GLOBAL_KEYWORD
	      Visual Studio project keyword.

	      Sets  the	 "keyword"  attribute  for  a  generated Visual Studio
	      project. Defaults to "Win32Proj". You may wish to override  this
	      value  with "ManagedCProj", for example, in a Visual Studio man‐
	      aged C++ unit test project.

       VS_GLOBAL_PROJECT_TYPES
	      Visual Studio project type(s).

	      Can be set to one or more UUIDs recognized by Visual  Studio  to
	      indicate the type of project. This value is copied verbatim into
	      the generated project file. Example for a managed C++ unit test‐
	      ing project:

	       {3AC096D0-A1C2-E12C-1390-A8335801FDAB};{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}

	      UUIDs are semicolon-delimited.

       VS_GLOBAL_ROOTNAMESPACE
	      Visual Studio project root namespace.

	      Sets the "RootNamespace" attribute for a generated Visual Studio
	      project.	The attribute will be generated only if this is set.

       VS_KEYWORD
	      Visual Studio project keyword.

	      Can be set to change the visual studio keyword, for  example  Qt
	      integration works better if this is set to Qt4VSv1.0.

       VS_SCC_AUXPATH
	      Visual Studio Source Code Control Aux Path.

	      Can  be set to change the visual studio source code control aux‐
	      path property.

	      project name property.

       VS_SCC_PROVIDER
	      Visual Studio Source Code Control Provider.

	      Can be set to change  the	 visual	 studio	 source	 code  control
	      provider property.

       VS_WINRT_EXTENSIONS
	      Visual  Studio  project  C++/CX  language extensions for Windows
	      Runtime

	      Can be set to enable C++/CX language extensions.

       VS_WINRT_REFERENCES
	      Visual Studio project Windows Runtime Metadata references

	      Adds one or more semicolon-delimited WinRT references to a  gen‐
	      erated   Visual	Studio	project.  For  example,	 "Windows;Win‐
	      dows.UI.Core".

       WIN32_EXECUTABLE
	      Build an executable with a WinMain entry point on windows.

	      When this property is set to true the executable when linked  on
	      Windows  will be created with a WinMain() entry point instead of
	      just main().  This makes it a GUI executable instead of  a  con‐
	      sole application.	 See the CMAKE_MFC_FLAG variable documentation
	      to configure use of MFC for WinMain executables.	This  property
	      is  initialized  by  the	value of the variable CMAKE_WIN32_EXE‐
	      CUTABLE if it is set when a target is created.

       XCODE_ATTRIBUTE_<an-attribute>
	      Set Xcode target attributes directly.

	      Tell the Xcode generator to  set	'<an-attribute>'  to  a	 given
	      value  in the generated Xcode project.  Ignored on other genera‐
	      tors.

PROPERTIES ON TESTS
       ATTACHED_FILES
	      Attach a list of files to a dashboard submission.

	      Set this property to a list of files that will  be  encoded  and
	      submitted to the dashboard as an addition to the test result.

       ATTACHED_FILES_ON_FAIL
	      Attach  a	 list  of  files to a dashboard submission if the test
	      fails.

	      Same as ATTACHED_FILES, but these files will only be included if
	      the test does not pass.

       COST   Set  this to a floating point value. Tests in a test set will be
	      run in descending order of cost.

	      This property describes the cost of a test. You  can  explicitly
	      set this value; tests with higher COST values will run first.

       DEPENDS
	      Specifies	 that this test should only be run after the specified
	      list of tests.

	      Set this to a list of tests that must finish before this test is
	      run.

       ENVIRONMENT
	      Specify environment variables that should be defined for running
	      a test.

	      If set to a list of environment variables and values of the form
	      MYVAR=value  those  environment  variables will be defined while
	      running the test. The environment is restored  to	 its  previous
	      state after the test is done.

       FAIL_REGULAR_EXPRESSION
	      If  the  output  matches	this  regular expression the test will
	      fail.

	      If set, if the output matches one of specified  regular  expres‐
	      sions,  the  test will fail.For example: FAIL_REGULAR_EXPRESSION
	      "[^a-z]Error;ERROR;Failed"

       LABELS Specify a list of text labels associated with a test.

	      The list is reported in dashboard submissions.

       MEASUREMENT
	      Specify a CDASH measurement and value to be reported for a test.

	      If set to a name then that name will be reported to CDASH	 as  a
	      named  measurement  with	a  value  of 1. You may also specify a
	      value by setting MEASUREMENT to "measurement=value".

       PASS_REGULAR_EXPRESSION
	      The output must match this regular expression for	 the  test  to
	      pass.

	      If  set,	the  test output will be checked against the specified
	      regular expressions and at least one of the regular  expressions
	      has to match, otherwise the test will fail.

       PROCESSORS
	      How many process slots this test requires

	      Denotes  the  number  of processors that this test will require.
	      This is typically used for MPI tests, and should be used in con‐
	      junction with the ctest_test PARALLEL_LEVEL option.

       REQUIRED_FILES
	      List of files required to run the test.

	      If  set  to a list of files, the test will not be run unless all
	      of the files exist.

       RESOURCE_LOCK
	      Specify a list of resources that are locked by this test.

	      If multiple tests specify the same resource lock, they are guar‐
	      anteed not to run concurrently.

       RUN_SERIAL
	      Do not run this test in parallel with any other test.

	      Use  this	 option	 in  conjunction  with	the  ctest_test PARAL‐
	      LEL_LEVEL option to specify that this test should not be run  in
	      parallel with any other tests.

       TIMEOUT
	      How many seconds to allow for this test.

	      This property if set will limit a test to not take more than the
	      specified number of seconds to run. If it exceeds that the  test
	      process  will  be	 killed	 and ctest will move to the next test.
	      This setting takes precedence over CTEST_TESTING_TIMEOUT.

       WILL_FAIL
	      If set to true, this will invert the pass/fail flag of the test.

	      This property can be used for tests that are  expected  to  fail
	      and return a non zero return code.

       WORKING_DIRECTORY
	      The directory from which the test executable will be called.

	      If this is not set it is called from the directory the test exe‐
	      cutable is located in.

PROPERTIES ON SOURCE FILES
       ABSTRACT
	      Is this source file an abstract class.

	      A property on a source file that indicates if  the  source  file
	      represents  a  class that is abstract. This only makes sense for
	      languages that have a notion of an abstract class and it is only
	      used by some tools that wrap classes into other languages.

       COMPILE_DEFINITIONS
	      Preprocessor definitions for compiling a source file.

	      The COMPILE_DEFINITIONS property may be set to a semicolon-sepa‐
	      rated list of preprocessor definitions using the syntax  VAR  or
	      VAR=value.  Function-style definitions are not supported.	 CMake
	      will automatically escape the value  correctly  for  the	native
	      build  system  (note  that  CMake	 language  syntax  may require
	      escapes to specify some values).	This property may be set on  a
	      per-configuration basis using the name COMPILE_DEFINITIONS_<CON‐
	      FIG> where <CONFIG> is an upper-case name (ex.  "COMPILE_DEFINI‐
	      TIONS_DEBUG").

	      CMake will automatically drop some definitions that are not sup‐
	      ported by the native build tool.	The VS6 IDE does  not  support
	      definition  values with spaces (but NMake does).	Xcode does not
	      support per-configuration definitions on source files.

	      Disclaimer: Most native build tools have poor support for escap‐
	      ing  certain  values.  CMake has work-arounds for many cases but
	      some values may just not be possible to pass  correctly.	 If  a
	      value  does  not seem to be escaped correctly, do not attempt to
	      work-around the problem by adding escape sequences to the value.
	      Your work-around may break in a future version of CMake that has
	      improved escape support.	Instead consider defining the macro in
	      a	 (configured) header file.  Then report the limitation.	 Known
	      limitations include:

		#	   - broken almost everywhere

	      CMake does not reject these values outright because they do work
	      in some cases.  Use with caution.

       COMPILE_DEFINITIONS_<CONFIG>
	      Per-configuration preprocessor definitions on a source file.

	      This  is	the  configuration-specific version of COMPILE_DEFINI‐
	      TIONS.  Note  that  Xcode	 does  not  support  per-configuration
	      source  file flags so this property will be ignored by the Xcode
	      generator.

       COMPILE_FLAGS
	      Additional flags to be added when compiling this source file.

	      These flags will be added to the list of compile flags when this
	      source  file builds.  Use COMPILE_DEFINITIONS to pass additional
	      preprocessor definitions.

       EXTERNAL_OBJECT
	      If set to true then this is an object file.

	      If this property is set to true then the source file  is	really
	      an  object  file	and  should not be compiled.  It will still be
	      linked into the target though.

       Fortran_FORMAT
	      Set to FIXED or FREE to indicate the Fortran source layout.

	      This property tells CMake whether a given	 Fortran  source  file
	      uses  fixed-format  or  free-format.  CMake will pass the corre‐
	      sponding format flag to the compiler.  Consider using  the  tar‐
	      get-wide Fortran_FORMAT property if all source files in a target
	      share the same format.

       GENERATED
	      Is this source file generated as part of the build process.

	      If a source file is generated by the build  process  CMake  will
	      handle  it differently in terms of dependency checking etc. Oth‐
	      erwise having a non-existent source file could create problems.

       HEADER_FILE_ONLY
	      Is this source file only a header file.

	      A property on a source file that indicates if the source file is
	      a	 header	 file  with  no associated implementation. This is set
	      automatically based on the file extension and is used  by	 CMake
	      to  determine  if	 certain dependency information should be com‐
	      puted.

       KEEP_EXTENSION
	      Make the output file have the same extension as the source file.

	      If this property is set then the file extension  of  the	output
	      file  will  be the same as that of the source file. Normally the
	      output file extension is computed based on the language  of  the
	      source file, for example .cxx will go to a .o extension.

       LABELS Specify a list of text labels associated with a source file.

	      This property has meaning only when the source file is listed in
	      a target whose LABELS property is also set.  No other  semantics
	      are currently specified.

       LANGUAGE
	      What programming language is the file.

	      A property that can be set to indicate what programming language
	      the source file is. If it is not set the language is  determined
	      based  on the file extension. Typical values are CXX C etc. Set‐
	      ting this property for a file means this file will be  compiled.
	      Do  not  set  this  for headers or files that should not be com‐
	      piled.

       LOCATION
	      The full path to a source file.

	      A read only property on a SOURCE FILE  that  contains  the  full
	      path to the source file.

       MACOSX_PACKAGE_LOCATION
	      Place  a	source	file  inside  a	 Mac OS X bundle, CFBundle, or
	      framework.

	      Executable targets with the MACOSX_BUNDLE property set are built
	      as  Mac  OS  X  application  bundles on Apple platforms.	Shared
	      library targets with the FRAMEWORK property set are built as Mac
	      OS X frameworks on Apple platforms.  Module library targets with
	      the BUNDLE property set are built as Mac OS X  CFBundle  bundles
	      on Apple platforms.  Source files listed in the target with this
	      property set will be copied to a directory inside the bundle  or
	      framework	 content  folder specified by the property value.  For
	      bundles the content folder is "<name>.app/Contents".  For frame‐
	      works  the  content  folder  is "<name>.framework/Versions/<ver‐
	      sion>".  For cfbundles the content folder is "<name>.bundle/Con‐
	      tents"   (unless	the  extension	is  changed).	See  the  PUB‐
	      LIC_HEADER, PRIVATE_HEADER, and RESOURCE target  properties  for
	      specifying files meant for Headers, PrivateHeaders, or Resources
	      directories.

       OBJECT_DEPENDS
	      Additional files on which a compiled object file depends.

	      Specifies a semicolon-separated list of full-paths to  files  on
	      which  any  object  files compiled from this source file depend.
	      An object file will be recompiled if any of the named  files  is
	      newer than it.

	      This  property  need  not be used to specify the dependency of a
	      source file  on  a  generated  header  file  that	 it  includes.
	      Although	the  property  was originally introduced for this pur‐
	      pose, it is no longer necessary.	If the generated  header  file
	      is  created by a custom command in the same target as the source
	      file, the automatic dependency scanning process  will  recognize
	      the  dependency.	 If  the  generated  header file is created by
	      another target, an inter-target  dependency  should  be  created
	      with the add_dependencies command (if one does not already exist
	      due to linking relationships).

       OBJECT_OUTPUTS
	      Additional outputs for a Makefile rule.

	      Additional outputs created by compilation of this	 source	 file.
	      If  any  of  these  outputs is missing the object will be recom‐
	      piled. This is supported only on Makefile generators and will be
	      ignored on other generators.

       SYMBOLIC
	      Is this just a name for a rule.

	      If  SYMBOLIC  (boolean)  is set to true the build system will be
	      informed that the source file is not actually  created  on  disk
	      but instead used as a symbolic name for a build rule.

       WRAP_EXCLUDE
	      Exclude this source file from any code wrapping techniques.

	      Some  packages can wrap source files into alternate languages to
	      provide additional functionality. For example, C++ code  can  be
	      wrapped  into Java or Python etc using SWIG etc. If WRAP_EXCLUDE
	      is set to true (1 etc) that  indicates  that  this  source  file
	      should not be wrapped.

PROPERTIES ON CACHE ENTRIES
       ADVANCED
	      True if entry should be hidden by default in GUIs.

	      This  is a boolean value indicating whether the entry is consid‐
	      ered  interesting	 only	for   advanced	 configuration.	   The
	      mark_as_advanced() command modifies this property.

       HELPSTRING
	      Help associated with entry in GUIs.

	      This string summarizes the purpose of an entry to help users set
	      it through a CMake GUI.

       MODIFIED
	      Internal management property.  Do not set or get.

	      This is an internal cache entry property	managed	 by  CMake  to
	      track interactive user modification of entries.  Ignore it.

       STRINGS
	      Enumerate possible STRING entry values for GUI selection.

	      For  cache  entries  with	 type STRING, this enumerates a set of
	      values.  CMake GUIs may use this to provide a  selection	widget
	      instead  of  a  generic  string entry field.  This is for conve‐
	      nience only.  CMake does not enforce that the value matches  one
	      of those listed.

       TYPE   Widget type for entry in GUIs.

	      Cache  entry  values  are always strings, but CMake GUIs present
	      widgets to help users set values.	 The GUIs use this property as
	      a hint to determine the widget type.  Valid TYPE values are:

		BOOL	      = Boolean ON/OFF value.
		PATH	      = Path to a directory.
		FILEPATH      = Path to a file.
		STRING	      = Generic string value.
		INTERNAL      = Do not present in GUI at all.
		STATIC	      = Value managed by CMake, do not change.
		UNINITIALIZED = Type not yet specified.

	      Generally the TYPE of a cache entry should be set by the command
	      which creates it (set, option, find_library, etc.).

       VALUE  Value of a cache entry.

	      This property maps to the actual value of a cache	 entry.	  Set‐
	      ting  this  property  always sets the value without checking, so
	      use with care.

COMPATIBILITY COMMANDS
	 CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.

       This is the documentation for now obsolete listfile commands from  pre‐
       vious  CMake versions, which are still supported for compatibility rea‐
       sons. You should instead use the newer, faster  and  shinier  new  com‐
       mands. ;-)

       build_name
	      Deprecated.    Use   ${CMAKE_SYSTEM}  and	 ${CMAKE_CXX_COMPILER}
	      instead.

		build_name(variable)

	      Sets the specified variable to a string representing  the	 plat‐
	      form  and	 compiler  settings.   These  values are now available
	      through the CMAKE_SYSTEM and CMAKE_CXX_COMPILER variables.

       exec_program
	      Deprecated.  Use the execute_process() command instead.

	      Run an executable program during the processing  of  the	CMake‐
	      List.txt file.

		exec_program(Executable [directory in which to run]
			     [ARGS <arguments to executable>]
			     [OUTPUT_VARIABLE <var>]
			     [RETURN_VALUE <var>])

	      The  executable  is  run	in the optionally specified directory.
	      The executable can include arguments if it is double quoted, but
	      it  is better to use the optional ARGS argument to specify argu‐
	      ments to the program.   This is because cmake will then be  able
	      to  escape  spaces in the executable path.  An optional argument
	      OUTPUT_VARIABLE specifies a variable in which to store the  out‐
	      put.  To	capture	 the  return value of the execution, provide a
	      RETURN_VALUE. If OUTPUT_VARIABLE is specified,  then  no	output
	      will go to the stdout/stderr of the console running cmake.

       export_library_dependencies
	      Deprecated.  Use INSTALL(EXPORT) or EXPORT command.

	      This  command  generates an old-style library dependencies file.
	      Projects requiring CMake 2.6 or later should not	use  the  com‐
	      mand.   Use  instead  the install(EXPORT) command to help export
	      targets from an installation tree and the	 export()  command  to
	      export targets from a build tree.

	      The  old-style  library  dependencies  file  does	 not take into
	      account per-configuration names of libraries or the  LINK_INTER‐
	      FACE_LIBRARIES target property.

		export_library_dependencies(<file> [APPEND])

	      Create  a	 file  named  <file> that can be included into a CMake
	      listfile with the INCLUDE command.  The file will contain a num‐
	      ber  of  SET commands that will set all the variables needed for
	      library dependency information.  This should be the last command
	      in  the  top  level  CMakeLists.txt file of the project.	If the
	      APPEND option is specified, the SET commands will be appended to
	      the given file instead of replacing it.

       install_files
	      Deprecated.  Use the install(FILES ) command instead.

	      This  command has been superceded by the install command.	 It is
	      provided for compatibility with older  CMake  code.   The	 FILES
	      form  is directly replaced by the FILES form of the install com‐
	      mand.  The regexp form can be expressed more clearly  using  the
	      GLOB form of the file command.

		install_files(<dir> extension file file ...)

	      Create  rules  to install the listed files with the given exten‐
	      sion into the given directory.  Only files existing in the  cur‐
	      rent  source  tree  or  its corresponding location in the binary
	      tree may be listed.  If a file specified already has  an	exten‐
	      sion,  that extension will be removed first.  This is useful for
	      providing lists of source files such as foo.cxx  when  you  want
	      the  corresponding foo.h to be installed. A typical extension is
	      '.h'.

		install_files(<dir> regexp)

	      Any files in the current source directory that match the regular
	      expression will be installed.

		install_files(<dir> FILES file file ...)

	      Any  files  listed  after	 the  FILES  keyword will be installed
	      explicitly from the names given.	Full paths are allowed in this
	      form.

	      The  directory  <dir>  is	 relative  to the installation prefix,
	      which is stored in the variable CMAKE_INSTALL_PREFIX.

       install_programs
	      Deprecated. Use the install(PROGRAMS ) command instead.

	      This command has been superceded by the install command.	It  is
	      provided	for  compatibility  with  older CMake code.  The FILES
	      form is directly replaced by the PROGRAMS form  of  the  INSTALL
	      command.	 The  regexp  form can be expressed more clearly using
	      the GLOB form of the FILE command.

		install_programs(<dir> file1 file2 [file3 ...])
		install_programs(<dir> FILES file1 [file2 ...])

	      Create rules to install  the  listed  programs  into  the	 given
	      directory.  Use  the  FILES  argument to guarantee that the file
	      list version of the command will be used even when there is only
	      one argument.

		install_programs(<dir> regexp)

	      In  the  second form any program in the current source directory
	      that matches the regular expression will be installed.

	      This command is intended to install programs that are not	 built
	      by  cmake,  such	as shell scripts.  See the TARGETS form of the
	      INSTALL command to create installation rules for	targets	 built
	      by cmake.

	      The  directory  <dir>  is	 relative  to the installation prefix,
	      which is stored in the variable CMAKE_INSTALL_PREFIX.

       install_targets
	      Deprecated. Use the install(TARGETS )  command instead.

	      This command has been superceded by the install command.	It  is
	      provided for compatibility with older CMake code.

		install_targets(<dir> [RUNTIME_DIRECTORY dir] target target)

	      Create rules to install the listed targets into the given direc‐
	      tory.  The directory <dir> is relative to the installation  pre‐
	      fix,  which  is  stored in the variable CMAKE_INSTALL_PREFIX. If
	      RUNTIME_DIRECTORY is specified, then  on	systems	 with  special
	      runtime  files  (Windows	DLL), the files will be copied to that
	      directory.

       link_libraries
	      Deprecated. Use the target_link_libraries() command instead.

	      Link libraries to all targets added later.

		link_libraries(library1 <debug | optimized> library2 ...)

	      Specify a list of libraries to be linked into any following tar‐
	      gets  (typically	added  with  the add_executable or add_library
	      calls).  This command is passed down to all subdirectories.  The
	      debug  and  optimized  strings  may be used to indicate that the
	      next library listed is to be used only for that specific type of
	      build.

       make_directory
	      Deprecated. Use the file(MAKE_DIRECTORY ) command instead.

		make_directory(directory)

	      Creates  the  specified  directory.  Full paths should be given.
	      Any parent directories that do not exist will also  be  created.
	      Use with care.

       output_required_files
	      Deprecated.  Approximate C preprocessor dependency scanning.

	      This command exists only because ancient CMake versions provided
	      it.  CMake handles preprocessor  dependency  scanning  automati‐
	      cally using a more advanced scanner.

		output_required_files(srcfile outputfile)

	      Outputs  a list of all the source files that are required by the
	      specified srcfile. This list is written into outputfile. This is
	      similar  to writing out the dependencies for srcfile except that
	      it jumps from .h files into .cxx, .c and .cpp files if possible.

       remove Deprecated. Use the list(REMOVE_ITEM ) command instead.

		remove(VAR VALUE VALUE ...)

	      Removes VALUE from the variable VAR.  This is typically used  to
	      remove  entries  from  a vector (e.g. semicolon separated list).
	      VALUE is expanded.

       subdir_depends
	      Deprecated.  Does nothing.

		subdir_depends(subdir dep1 dep2 ...)

	      Does not do anything.  This command used to help projects	 order
	      parallel builds correctly.  This functionality is now automatic.

       subdirs
	      Deprecated. Use the add_subdirectory() command instead.

	      Add a list of subdirectories to the build.

		subdirs(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...]
			[PREORDER] )

	      Add  a list of subdirectories to the build. The add_subdirectory
	      command should be used instead of subdirs although subdirs  will
	      still  work. This will cause any CMakeLists.txt files in the sub
	      directories to be processed by CMake.  Any directories after the
	      PREORDER	flag  are traversed first by makefile builds, the PRE‐
	      ORDER flag has no effect on IDE projects.	 Any directories after
	      the  EXCLUDE_FROM_ALL  marker  will  not	be included in the top
	      level makefile or project file. This is useful for having	 CMake
	      create makefiles or projects for a set of examples in a project.
	      You would want CMake to generate makefiles or project files  for
	      all  the	examples at the same time, but you would not want them
	      to show up in the top level project or be built each  time  make
	      is run from the top.

       use_mangled_mesa
	      Copy mesa headers for use in combination with system GL.

		use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY)

	      The path to mesa includes, should contain gl_mangle.h.  The mesa
	      headers are copied to  the  specified  output  directory.	  This
	      allows  mangled  mesa  headers  to  override other GL headers by
	      being added to the include directory path earlier.

       utility_source
	      Specify the source tree of a third-party utility.

		utility_source(cache_entry executable_name
			       path_to_source [file1 file2 ...])

	      When a third-party utility's source is included in the distribu‐
	      tion,  this  command specifies its location and name.  The cache
	      entry will not be set unless the path_to_source and  all	listed
	      files  exist.  It is assumed that the source tree of the utility
	      will have been built before it is needed.

	      When cross compiling CMake will  print  a	 warning  if  a	 util‐
	      ity_source()  command  is	 executed, because in many cases it is
	      used to build an executable which is  executed  later  on.  This
	      doesn't  work when cross compiling, since the executable can run
	      only on their target platform. So in this case the  cache	 entry
	      has  to be adjusted manually so it points to an executable which
	      is runnable on the build host.

       variable_requires
	      Deprecated. Use the if() command instead.

	      Assert satisfaction of an option's required variables.

		variable_requires(TEST_VARIABLE RESULT_VARIABLE
				  REQUIRED_VARIABLE1
				  REQUIRED_VARIABLE2 ...)

	      The first argument (TEST_VARIABLE) is the name of	 the  variable
	      to be tested, if that variable is false nothing else is done. If
	      TEST_VARIABLE is true, then the next argument  (RESULT_VARIABLE)
	      is  a variable that is set to true if all the required variables
	      are set. The rest of the arguments are variables	that  must  be
	      true  or	not set to NOTFOUND to avoid an error.	If any are not
	      true, an error is reported.

       write_file
	      Deprecated. Use the file(WRITE ) command instead.

		write_file(filename "message to write"... [APPEND])

	      The first argument is the file name, the rest of	the  arguments
	      are messages to write. If the argument APPEND is specified, then
	      the message will be appended.

	      NOTE 1: file(WRITE ... and file(APPEND ... do exactly  the  same
	      as this one but add some more functionality.

	      NOTE  2:	When using write_file the produced file cannot be used
	      as an input to CMake (CONFIGURE_FILE, source file	 ...)  because
	      it will lead to an infinite loop. Use configure_file if you want
	      to generate input files to CMake.

MODULES
       The following modules are provided with CMake. They can	be  used  with
       INCLUDE(ModuleName).

	 CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.

       This  is	 the  documentation  for  the  modules and scripts coming with
       CMake. Using these modules  you	can  check  the	 computer  system  for
       installed software packages, features of the compiler and the existence
       of headers to name just a few.

       AddFileDependencies
	      ADD_FILE_DEPENDENCIES(source_file depend_files...)

	      Adds the given files as dependencies to source_file

       BundleUtilities
	      Functions to help assemble a standalone bundle application.

	      A collection of CMake utility functions useful for dealing  with
	      .app bundles on the Mac and bundle-like directories on any OS.

	      The following functions are provided by this module:

		 fixup_bundle
		 copy_and_fixup_bundle
		 verify_app
		 get_bundle_main_executable
		 get_dotapp_dir
		 get_bundle_and_executable
		 get_bundle_all_executables
		 get_item_key
		 clear_bundle_keys
		 set_bundle_key_values
		 get_bundle_keys
		 copy_resolved_item_into_bundle
		 copy_resolved_framework_into_bundle
		 fixup_bundle_item
		 verify_bundle_prerequisites
		 verify_bundle_symlinks

	      Requires	CMake  2.6  or greater because it uses function, break
	      and PARENT_SCOPE. Also depends on GetPrerequisites.cmake.

		FIXUP_BUNDLE(<app> <libs> <dirs>)

	      Fix up a bundle in-place and make it standalone,	such  that  it
	      can  be  drag-n-drop  copied  to another machine and run on that
	      machine as long as all of the system libraries are compatible.

	      If you pass plugins to fixup_bundle as the libs  parameter,  you
	      should  install them or copy them into the bundle before calling
	      fixup_bundle. The "libs" parameter is a list of  libraries  that
	      must  be fixed up, but that cannot be determined by otool output
	      analysis. (i.e., plugins)

	      Gather all the keys for all the executables and libraries	 in  a
	      bundle,  and then, for each key, copy each prerequisite into the
	      bundle. Then fix each one up according to its own list  of  pre‐
	      requisites.

	      Then  clear all the keys and call verify_app on the final bundle
	      to ensure that it is truly standalone.

		COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)

	      Makes a copy of the bundle <src>	at  location  <dst>  and  then
	      fixes up the new copied bundle in-place at <dst>...

		VERIFY_APP(<app>)

	      Verifies	that  an application <app> appears valid based on run‐
	      ning analysis tools on it. Calls	"message(FATAL_ERROR"  if  the
	      application is not verified.

		GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)

	      The  result will be the full path name of the bundle's main exe‐
	      cutable file or an "error:" prefixed string if it could  not  be
	      determined.

		GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)

	      Returns the nearest parent dir whose name ends with ".app" given
	      the full path to an executable. If there is no such parent  dir,
	      then simply return the dir containing the executable.

	      The returned directory may or may not exist.

		GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)

	      Takes  either  a	".app"	directory  name or the name of an exe‐
	      cutable nested inside a ".app" directory and returns the path to
	      the  ".app"  directory  in <bundle_var> and the path to its main
	      executable in <executable_var>

		GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)

	      Scans the given bundle recursively for all executable files  and
	      accumulates them into a variable.

		GET_ITEM_KEY(<item> <key_var>)

	      Given  a	file (item) name, generate a key that should be unique
	      considering the set of libraries that need copying or fixing  up
	      to  make	a bundle standalone. This is essentially the file name
	      including extension with "." replaced by "_"

	      This key is used as a prefix for CMake variables so that we  can
	      associate a set of variables with a given item based on its key.

		CLEAR_BUNDLE_KEYS(<keys_var>)

	      Loop  over  the list of keys, clearing all the variables associ‐
	      ated with each key. After the  loop,  clear  the	list  of  keys
	      itself.

	      Caller  of  get_bundle_keys  should  call clear_bundle_keys when
	      done with list of keys.

		SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
				      <copyflag>)

	      Add a key to the list (if necessary)  for	 the  given  item.  If
	      added, also set all the variables associated with that key.

		GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)

	      Loop over all the executable and library files within the bundle
	      (and given as extra <libs>) and accumulate a list of keys repre‐
	      senting  them.  Set values associated with each key such that we
	      can loop over all of them and copy prerequisite  libs  into  the
	      bundle and then do appropriate install_name_tool fixups.

		COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

	      Copy  a  resolved item into the bundle if necessary. Copy is not
	      necessary	 if  the  resolved_item	  is   "the   same   as"   the
	      resolved_embedded_item.

		COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

	      Copy  a resolved framework into the bundle if necessary. Copy is
	      not  necessary  if  the  resolved_item  is  "the	same  as"  the
	      resolved_embedded_item.

	      By  default,  BU_COPY_FULL_FRAMEWORK_CONTENTS is not set. If you
	      want   full   frameworks	 embedded   in	 your	bundles,   set
	      BU_COPY_FULL_FRAMEWORK_CONTENTS  to ON before calling fixup_bun‐
	      dle. By default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies  the
	      framework dylib itself plus the framework Resources directory.

		FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)

	      Get the direct/non-system prerequisites of the resolved embedded
	      item. For each prerequisite, change the way it is referenced  to
	      the  value of the _EMBEDDED_ITEM keyed variable for that prereq‐
	      uisite. (Most likely changing  to	 an  "@executable_path"	 style
	      reference.)

	      This   function  requires	 that  the  resolved_embedded_item  be
	      "inside" the bundle already. In other words, if you pass plugins
	      to  fixup_bundle	as the libs parameter, you should install them
	      or copy them into the bundle before  calling  fixup_bundle.  The
	      "libs"  parameter	 is a list of libraries that must be fixed up,
	      but that cannot be determined by otool output  analysis.	(i.e.,
	      plugins)

	      Also,  change  the  id  of  the  item  being fixed up to its own
	      _EMBEDDED_ITEM value.

	      Accumulate changes in a local variable and make  *one*  call  to
	      install_name_tool	 at  the  end  of  the	function  with all the
	      changes at once.

	      If the BU_CHMOD_BUNDLE_ITEMS variable is set then	 bundle	 items
	      will be marked writable before install_name_tool tries to change
	      them.

		VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)

	      Verifies that the sum of all prerequisites of all	 files	inside
	      the  bundle  are	contained  within  the	bundle or are "system"
	      libraries, presumed to exist everywhere.

		VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)

	      Verifies that any symlinks found in the bundle  point  to	 other
	      files  that  are	already	 also  in  the bundle... Anything that
	      points to an external file causes this function to fail the ver‐
	      ification.

       CMakeAddFortranSubdirectory
	      Use MinGW gfortran from VS if a fortran compiler is not found.

	      The 'add_fortran_subdirectory' function adds a subdirectory to a
	      project that contains a fortran  only  sub-project.  The	module
	      will  check  the current compiler and see if it can support for‐
	      tran. If no fortran compiler is found and the compiler is	 MSVC,
	      then this module will find the MinGW gfortran.  It will then use
	      an external project to build with the MinGW tools.  It will also
	      create  imported	targets	 for the libraries created.  This will
	      only  work  if  the  fortran  code  is  built  into  a  dll,  so
	      BUILD_SHARED_LIBS	 is turned on in the project.  In addition the
	      CMAKE_GNUtoMS option is set to on, so that the MS .lib files are
	      created. Usage is as follows:

		cmake_add_fortran_subdirectory(
		 <subdir>		 # name of subdirectory
		 PROJECT <project_name>	 # project name in subdir top CMakeLists.txt
		 ARCHIVE_DIR <dir>	 # dir where project places .lib files
		 RUNTIME_DIR <dir>	 # dir where project places .dll files
		 LIBRARIES <lib>...	 # names of library targets to import
		 LINK_LIBRARIES		 # link interface libraries for LIBRARIES
		  [LINK_LIBS <lib> <dep>...]...
		 CMAKE_COMMAND_LINE ...	 # extra command line flags to pass to cmake
		 NO_EXTERNAL_INSTALL	 # skip installation of external project
		 )

	      Relative	paths  in  ARCHIVE_DIR and RUNTIME_DIR are interpreted
	      with respect to the build directory corresponding to the	source
	      directory in which the function is invoked.

	      Limitations:

	      NO_EXTERNAL_INSTALL is required for forward compatibility with a
	      future  version  that  supports  installation  of	 the  external
	      project binaries during "make install".

       CMakeBackwardCompatibilityCXX
	      define a bunch of backwards compatibility variables

		CMAKE_ANSI_CXXFLAGS - flag for ansi c++
		CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
		include(TestForANSIStreamHeaders)
		include(CheckIncludeFileCXX)
		include(TestForSTDNamespace)
		include(TestForANSIForScope)

       CMakeDependentOption
	      Macro to provide an option dependent on other options.

	      This macro presents an option to the user only if a set of other
	      conditions are true.  When the option is not presented a default
	      value  is	 used,	but any value set by the user is preserved for
	      when the option is presented again. Example invocation:

		CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
				       "USE_BAR;NOT USE_ZOT" OFF)

	      If USE_BAR is true and USE_ZOT is false, this provides an option
	      called  USE_FOO that defaults to ON.  Otherwise, it sets USE_FOO
	      to OFF.  If the status of USE_BAR or USE_ZOT ever	 changes,  any
	      value for the USE_FOO option is saved so that when the option is
	      re-enabled it retains its old value.

       CMakeDetermineVSServicePack
	      Determine the Visual Studio service pack of the 'cl' in use.

	      The functionality of this module	has  been  superseded  by  the
	      platform	variable  CMAKE_<LANG>_COMPILER_VERSION	 that contains
	      the compiler version number.

	      Usage:

		if(MSVC)
		  include(CMakeDetermineVSServicePack)
		  DetermineVSServicePack( my_service_pack )
		  if( my_service_pack )
		    message(STATUS "Detected: ${my_service_pack}")
		  endif()
		endif()

	      Function DetermineVSServicePack sets the given variable  to  one
	      of the following values or an empty string if unknown:

		vc80, vc80sp1
		vc90, vc90sp1
		vc100, vc100sp1
		vc110, vc110sp1, vc110sp2

       CMakeExpandImportedTargets

	      CMAKE_EXPAND_IMPORTED_TARGETS(<var> LIBRARIES lib1 lib2...libN

						   [CONFIGURATION <config>] )

	      CMAKE_EXPAND_IMPORTED_TARGETS()  takes  a	 list of libraries and
	      replaces all imported targets contained in this list with	 their
	      actual file paths of the referenced libraries on disk, including
	      the libraries from their link interfaces. If a CONFIGURATION  is
	      given, it uses the respective configuration of the imported tar‐
	      gets if it exists. If no CONFIGURATION is	 given,	 it  uses  the
	      first  configuration  from  ${CMAKE_CONFIGURATION_TYPES} if set,
	      otherwise	 ${CMAKE_BUILD_TYPE}.  This  macro  is	used  by   all
	      Check*.cmake files which use try_compile() or try_run() and sup‐
	      port CMAKE_REQUIRED_LIBRARIES , so  that	these  checks  support
	      imported targets in CMAKE_REQUIRED_LIBRARIES:

		  cmake_expand_imported_targets(expandedLibs LIBRARIES ${CMAKE_REQUIRED_LIBRARIES}
							     CONFIGURATION "${CMAKE_TRY_COMPILE_CONFIGURATION}" )

       CMakeFindFrameworks
	      helper module to find OSX frameworks

       CMakeFindPackageMode

	      This file is executed by cmake when invoked with --find-package.
	      It expects that the following variables are set using -D:

		 NAME = name of the package
		 COMPILER_ID = the CMake compiler ID for which the result is, i.e. GNU/Intel/Clang/MSVC, etc.
		 LANGUAGE = language for which the result will be used, i.e. C/CXX/Fortan/ASM
		 MODE = EXIST : only check for existence of the given package
			COMPILE : print the flags needed for compiling an object file which uses the given package
			LINK : print the flags needed for linking when using the given package
		 QUIET = if TRUE, don't print anything

       CMakeForceCompiler

	      This module defines macros intended for use  by  cross-compiling
	      toolchain	 files	when CMake is not able to automatically detect
	      the compiler identification.

	      Macro CMAKE_FORCE_C_COMPILER has the following signature:

		 CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

	      It sets CMAKE_C_COMPILER to the given  compiler  and  the	 cmake
	      internal	variable CMAKE_C_COMPILER_ID to the given compiler-id.
	      It also bypasses the check for working compiler and  basic  com‐
	      piler information tests.

	      Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

		 CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

	      It  sets	CMAKE_CXX_COMPILER to the given compiler and the cmake
	      internal	variable  CMAKE_CXX_COMPILER_ID	 to  the  given	  com‐
	      piler-id.	 It  also  bypasses the check for working compiler and
	      basic compiler information tests.

	      Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:

		 CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>)

	      It sets CMAKE_Fortran_COMPILER to the  given  compiler  and  the
	      cmake  internal  variable CMAKE_Fortran_COMPILER_ID to the given
	      compiler-id. It also bypasses the check for working compiler and
	      basic compiler information tests.

	      So a simple toolchain file could look like this:

		 include (CMakeForceCompiler)
		 set(CMAKE_SYSTEM_NAME Generic)
		 CMAKE_FORCE_C_COMPILER	  (chc12 MetrowerksHicross)
		 CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)

       CMakeGraphVizOptions
	      The builtin graphviz support of CMake.

	      CMake  can  generate  graphviz  files,  showing the dependencies
	      between the targets in a project	and  also  external  libraries
	      which  are  linked  against.  When  CMake is run with the --gra‐
	      phiz=foo option, it will produce

		  * a foo.dot file showing all dependencies in the project
		  * a foo.dot.<target> file for each target, file showing on which other targets the respective target depends
		  * a foo.dot.<target>.dependers file, showing which other targets depend on the respective target

	      This can result in huge graphs. Using the file  CMakeGraphVizOp‐
	      tions.cmake  the look and content of the generated graphs can be
	      influenced. This file is searched first  in  ${CMAKE_BINARY_DIR}
	      and  then	 in  ${CMAKE_SOURCE_DIR}. If found, it is read and the
	      variables set in it are used to adjust options for the generated
	      graphviz files.

		GRAPHVIZ_GRAPH_TYPE - The graph type
		   Mandatory : NO
		   Default   : "digraph"
		GRAPHVIZ_GRAPH_NAME - The graph name.
		   Mandatory : NO
		   Default   : "GG"
		GRAPHVIZ_GRAPH_HEADER - The header written at the top of the graphviz file.
		   Mandatory : NO
		   Default   : "node [n	 fontsize = "12"];"
		GRAPHVIZ_NODE_PREFIX - The prefix for each node in the graphviz file.
		   Mandatory : NO
		   Default   : "node"
		GRAPHVIZ_EXECUTABLES - Set this to FALSE to exclude executables from the generated graphs.
		   Mandatory : NO
		   Default   : TRUE
		GRAPHVIZ_STATIC_LIBS - Set this to FALSE to exclude static libraries from the generated graphs.
		   Mandatory : NO
		   Default   : TRUE
		GRAPHVIZ_SHARED_LIBS - Set this to FALSE to exclude shared libraries from the generated graphs.
		   Mandatory : NO
		   Default   : TRUE
		GRAPHVIZ_MODULE_LIBS - Set this to FALSE to exclude static libraries from the generated graphs.
		   Mandatory : NO
		   Default   : TRUE
		GRAPHVIZ_EXTERNAL_LIBS - Set this to FALSE to exclude external libraries from the generated graphs.
		   Mandatory : NO
		   Default   : TRUE
		GRAPHVIZ_IGNORE_TARGETS - A list of regular expressions for ignoring targets.
		   Mandatory : NO
		   Default   : empty

       CMakePackageConfigHelpers
	      CONFIGURE_PACKAGE_CONFIG_FILE(),	      WRITE_BASIC_PACKAGE_VER‐
	      SION_FILE()

		  CONFIGURE_PACKAGE_CONFIG_FILE(<input> <output> INSTALL_DESTINATION <path>
								 [PATH_VARS <var1> <var2> ... <varN>]
								 [NO_SET_AND_CHECK_MACRO]
								 [NO_CHECK_REQUIRED_COMPONENTS_MACRO])

	      CONFIGURE_PACKAGE_CONFIG_FILE() should be used  instead  of  the
	      plain  configure_file()  command	when  creating	the <Name>Con‐
	      fig.cmake or <Name>-config.cmake file for installing  a  project
	      or library. It helps making the resulting package relocatable by
	      avoiding hardcoded paths in the installed Config.cmake file.

	      In a FooConfig.cmake file there may be code like	this  to  make
	      the install destinations know to the using project:

		 set(FOO_INCLUDE_DIR   "@CMAKE_INSTALL_FULL_INCLUDEDIR@" )
		 set(FOO_DATA_DIR   "@CMAKE_INSTALL_PREFIX@/@RELATIVE_DATA_INSTALL_DIR@" )
		 set(FOO_ICONS_DIR   "@CMAKE_INSTALL_PREFIX@/share/icons" )
		 ...logic to determine installedPrefix from the own location...
		 set(FOO_CONFIG_DIR  "${installedPrefix}/@CONFIG_INSTALL_DIR@" )

	      All  4 options shown above are not sufficient, since the first 3
	      hardcode the absolute directory  locations,  and	the  4th  case
	      works only if the logic to determine the installedPrefix is cor‐
	      rect, and if CONFIG_INSTALL_DIR contains a relative path,	 which
	      in  general  cannot  be guaranteed. This has the effect that the
	      resulting FooConfig.cmake file would work poorly	under  Windows
	      and  OSX, where users are used to choose the install location of
	      a	 binary	 package  at  install  time,  independent   from   how
	      CMAKE_INSTALL_PREFIX was set at build/cmake time.

	      Using  CONFIGURE_PACKAGE_CONFIG_FILE() helps. If used correctly,
	      it makes the resulting FooConfig.cmake file relocatable. Usage:

		 1. write a FooConfig.cmake.in file as you are used to
		 2. insert a line containing only the string "@PACKAGE_INIT@"
		 3. instead of set(FOO_DIR "@SOME_INSTALL_DIR@"), use set(FOO_DIR "@PACKAGE_SOME_INSTALL_DIR@")
		    (this must be after the @PACKAGE_INIT@ line)
		 4. instead of using the normal configure_file(), use CONFIGURE_PACKAGE_CONFIG_FILE()

	      The <input> and <output> arguments  are  the  input  and	output
	      file, the same way as in configure_file().

	      The  <path> given to INSTALL_DESTINATION must be the destination
	      where the FooConfig.cmake file will be installed	to.  This  can
	      either be a relative or absolute path, both work.

	      The  variables <var1> to <varN> given as PATH_VARS are the vari‐
	      ables which contain install destinations. For each of  them  the
	      macro  will  create  a  helper  variable PACKAGE_<var...>. These
	      helper variables must be used in the FooConfig.cmake.in file for
	      setting  the  installed location. They are calculated by CONFIG‐
	      URE_PACKAGE_CONFIG_FILE() so that they are  always  relative  to
	      the installed location of the package. This works both for rela‐
	      tive and also for absolute locations. For absolute locations  it
	      works  only  if  the  absolute  location	is  a  subdirectory of
	      CMAKE_INSTALL_PREFIX.

	      By default configure_package_config_file()  also	generates  two
	      helper  macros,  set_and_check() and check_required_components()
	      into the FooConfig.cmake file.

	      set_and_check() should be used instead of the normal set()  com‐
	      mand for setting directories and file locations. Additionally to
	      setting the variable it also checks that the referenced file  or
	      directory	 actually  exists  and fails with a FATAL_ERROR other‐
	      wise. This makes sure that the created FooConfig.cmake file does
	      not     contain	  wrong	   references.	  When	  using	   the
	      NO_SET_AND_CHECK_MACRO, this macro is  not  generated  into  the
	      FooConfig.cmake file.

	      check_required_components(<package_name>)	 should	 be  called at
	      the end of the FooConfig.cmake file if the package supports com‐
	      ponents.	This  macro checks whether all requested, non-optional
	      components have been found, and if this is not  the  case,  sets
	      the  Foo_FOUND variable to FALSE, so that the package is consid‐
	      ered to be not found. It does that by  testing  the  Foo_<Compo‐
	      nent>_FOUND  variables  for  all	requested required components.
	      When using the NO_CHECK_REQUIRED_COMPONENTS option,  this	 macro
	      is not generated into the FooConfig.cmake file.

	      For an example see below the documentation for WRITE_BASIC_PACK‐
	      AGE_VERSION_FILE().

		WRITE_BASIC_PACKAGE_VERSION_FILE( filename VERSION major.minor.patch COMPATIBILITY (AnyNewerVersion|SameMajorVersion|ExactVersion) )

	      Writes a file for use as	<package>ConfigVersion.cmake  file  to
	      <filename>.  See the documentation of find_package() for details
	      on this.

		  filename is the output filename, it should be in the build tree.
		  major.minor.patch is the version number of the project to be installed

	      The COMPATIBILITY mode AnyNewerVersion means that the  installed
	      package  version will be considered compatible if it is newer or
	      exactly the same as the requested version. This mode  should  be
	      used  for	 packages  which  are  fully backward compatible, also
	      across major versions. If SameMajorVersion is used instead, then
	      the  behaviour  differs  from  AnyNewerVersion in that the major
	      version number must be the same as requested, e.g.  version  2.0
	      will not be considered compatible if 1.0 is requested. This mode
	      should be used for packages which guarantee backward compatibil‐
	      ity within the same major version. If ExactVersion is used, then
	      the package is only considered compatible if the requested  ver‐
	      sion matches exactly its own version number (not considering the
	      tweak version). For example, version 1.2.3 of a package is  only
	      considered  compatible  to requested version 1.2.3. This mode is
	      for packages without compatibility guarantees. If	 your  project
	      has  more	 elaborated  version  matching rules, you will need to
	      write your own custom ConfigVersion.cmake file instead of	 using
	      this macro.

	      Internally,  this	 macro executes configure_file() to create the
	      resulting version file. Depending on  the	 COMPATIBLITY,	either
	      the  file BasicConfigVersion-SameMajorVersion.cmake.in or Basic‐
	      ConfigVersion-AnyNewerVersion.cmake.in is used. Please note that
	      these  two  files	 are internal to CMake and you should not call
	      configure_file() on them yourself,  but  they  can  be  used  as
	      starting	point  to  create  more sophisticted custom ConfigVer‐
	      sion.cmake files.

	      Example	using	both	configure_package_config_file()	   and
	      write_basic_package_version_file(): CMakeLists.txt:

		 set(INCLUDE_INSTALL_DIR include/ ... CACHE )
		 set(LIB_INSTALL_DIR lib/ ... CACHE )
		 set(SYSCONFIG_INSTALL_DIR etc/foo/ ... CACHE )
		 ...
		 include(CMakePackageConfigHelpers)
		 configure_package_config_file(FooConfig.cmake.in ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake
					       INSTALL_DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake
					       PATH_VARS INCLUDE_INSTALL_DIR SYSCONFIG_INSTALL_DIR)
		 write_basic_package_version_file(${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
						  VERSION 1.2.3
						  COMPATIBILITY SameMajorVersion )
		 install(FILES ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake ${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
			 DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake )

	      With a FooConfig.cmake.in:

		 set(FOO_VERSION x.y.z)
		 ...
		 @PACKAGE_INIT@
		 ...
		 set_and_check(FOO_INCLUDE_DIR "@PACKAGE_INCLUDE_INSTALL_DIR@")
		 set_and_check(FOO_SYSCONFIG_DIR "@PACKAGE_SYSCONFIG_INSTALL_DIR@")

		 check_required_components(Foo)

       CMakeParseArguments

	      CMAKE_PARSE_ARGUMENTS(<prefix>   <options>  <one_value_keywords>
	      <multi_value_keywords> args...)

	      CMAKE_PARSE_ARGUMENTS() is intended to  be  used	in  macros  or
	      functions for parsing the arguments given to that macro or func‐
	      tion. It processes the arguments and defines a set of  variables
	      which hold the values of the respective options.

	      The  <options>  argument contains all options for the respective
	      macro, i.e. keywords which can be used when  calling  the	 macro
	      without  any  value following, like e.g. the OPTIONAL keyword of
	      the install() command.

	      The <one_value_keywords> argument contains all keywords for this
	      macro  which  are	 followed  by one value, like e.g. DESTINATION
	      keyword of the install() command.

	      The <multi_value_keywords> argument contains  all	 keywords  for
	      this  macro  which  can be followed by more than one value, like
	      e.g. the TARGETS or FILES keywords of the install() command.

	      When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of
	      the  keywords  listed  in	 <options>,  <one_value_keywords>  and
	      <multi_value_keywords> a variable composed of the given <prefix>
	      followed	by  "_"	 and the name of the respective keyword. These
	      variables will then hold the respective value from the  argument
	      list. For the <options> keywords this will be TRUE or FALSE.

	      All  remaining  arguments	 are  collected	 in  a	variable <pre‐
	      fix>_UNPARSED_ARGUMENTS, this can be checked afterwards  to  see
	      whether your macro was called with unrecognized parameters.

	      As  an  example  here  a my_install() macro, which takes similar
	      arguments as the real install() command:

		 function(MY_INSTALL)
		   set(options OPTIONAL FAST)
		   set(oneValueArgs DESTINATION RENAME)
		   set(multiValueArgs TARGETS CONFIGURATIONS)
		   cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} )
		   ...

	      Assume my_install() has been called like this:

		 my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)

	      After the cmake_parse_arguments() call the macro will  have  set
	      the following variables:

		 MY_INSTALL_OPTIONAL = TRUE
		 MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
		 MY_INSTALL_DESTINATION = "bin"
		 MY_INSTALL_RENAME = "" (was not used)
		 MY_INSTALL_TARGETS = "foo;bar"
		 MY_INSTALL_CONFIGURATIONS = "" (was not used)
		 MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"

	      You can then continue and process these variables.

	      Keywords	terminate  lists  of  values, e.g. if directly after a
	      one_value_keyword another recognized keyword  follows,  this  is
	      interpreted   as	 the   beginning   of  the  new	 option.  E.g.
	      my_install(TARGETS foo DESTINATION  OPTIONAL)  would  result  in
	      MY_INSTALL_DESTINATION  set to "OPTIONAL", but MY_INSTALL_DESTI‐
	      NATION would be empty and MY_INSTALL_OPTIONAL would  be  set  to
	      TRUE therefor.

       CMakePrintHelpers
	      Convenience macros for printing properties and variables, useful
	      e.g. for debugging.

	      CMAKE_PRINT_PROPERTIES([TARGETS target1 .. targetN]

				      [SOURCES source1 .. sourceN]
				      [DIRECTORIES dir1 .. dirN]
				      [TESTS test1 .. testN]
				      [CACHE_ENTRIES entry1 .. entryN]
				      PROPERTIES prop1 .. propN )

	      This macro prints the values of the properties of the given tar‐
	      gets, source files, directories, tests or cache entries. Exactly
	      one of the scope keywords must be used. Example:

		 cmake_print_properties(TARGETS foo bar PROPERTIES LOCATION INTERFACE_INCLUDE_DIRS)

	      This will print the LOCATION and INTERFACE_INCLUDE_DIRS  proper‐
	      ties for both targets foo and bar.

	      CMAKE_PRINT_VARIABLES(var1 var2 .. varN)

	      This  macro will print the name of each variable followed by its
	      value. Example:

		 cmake_print_variables(CMAKE_C_COMPILER CMAKE_MAJOR_VERSION THIS_ONE_DOES_NOT_EXIST)

	      Gives:

		 -- CMAKE_C_COMPILER="/usr/bin/gcc" ; CMAKE_MAJOR_VERSION="2" ; THIS_ONE_DOES_NOT_EXIST=""

       CMakePrintSystemInformation
	      print system information

	      This file can be used for diagnostic purposes just include it in
	      a project to see various internal CMake variables.

       CMakePushCheckState

	      This   module  defines  three  macros:  CMAKE_PUSH_CHECK_STATE()
	      CMAKE_POP_CHECK_STATE()  and   CMAKE_RESET_CHECK_STATE()	 These
	      macros  can be used to save, restore and reset (i.e., clear con‐
	      tents)  the  state  of   the   variables	 CMAKE_REQUIRED_FLAGS,
	      CMAKE_REQUIRED_DEFINITIONS,     CMAKE_REQUIRED_LIBRARIES	   and
	      CMAKE_REQUIRED_INCLUDES used by the various  Check-files	coming
	      with  CMake, like e.g. check_function_exists() etc. The variable
	      contents are pushed on a stack, pushing multiple times  is  sup‐
	      ported.  This  is	 useful	 e.g.  when  executing such tests in a
	      Find-module, where they have to be set, but after the  Find-mod‐
	      ule  has	been  executed they should have the same value as they
	      had before.

	      CMAKE_PUSH_CHECK_STATE() macro receives optional argument RESET.
	      Whether  it's  specified,	 CMAKE_PUSH_CHECK_STATE() will set all
	      CMAKE_REQUIRED_*	 variables   to	  empty	  values,   same    as
	      CMAKE_RESET_CHECK_STATE() call will do.

	      Usage:

		 cmake_push_check_state(RESET)
		 set(CMAKE_REQUIRED_DEFINITIONS -DSOME_MORE_DEF)
		 check_function_exists(...)
		 cmake_reset_check_state()
		 set(CMAKE_REQUIRED_DEFINITIONS -DANOTHER_DEF)
		 check_function_exists(...)
		 cmake_pop_check_state()

       CMakeVerifyManifest

	      CMakeVerifyManifest.cmake

	      This script is used to verify that embeded manifests and side by
	      side manifests for a project match.  To run this script, cd to a
	      directory	 and run the script with cmake -P. On the command line
	      you can pass in versions that are OK even if not	found  in  the
	      .manifest files. For example, cmake -Dallow_versions=8.0.50608.0
	      -PCmakeVerifyManifest.cmake could be used to  allow  an  embeded
	      manifest	of  8.0.50608.0	 to  be used in a project even if that
	      version was not found in the .manifest file.

       CPack  Build binary and source package installers.

	      The CPack module generates binary and  source  installers	 in  a
	      variety  of  formats  using  the cpack program. Inclusion of the
	      CPack module adds two new targets to  the	 resulting  makefiles,
	      package  and  package_source,  which build the binary and source
	      installers, respectively. The generated binary  installers  con‐
	      tain  everything	installed via CMake's INSTALL command (and the
	      deprecated INSTALL_FILES, INSTALL_PROGRAMS, and  INSTALL_TARGETS
	      commands).

	      For  certain kinds of binary installers (including the graphical
	      installers on Mac OS X and Windows), CPack generates  installers
	      that  allow users to select individual application components to
	      install. See CPackComponent module for that.

	      The CPACK_GENERATOR variable has different meanings in different
	      contexts.	 In  your  CMakeLists.txt  file,  CPACK_GENERATOR is a
	      *list of generators*: when run with no  other  arguments,	 CPack
	      will  iterate  over  that	 list and produce one package for each
	      generator. In a CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERA‐
	      TOR  is  a  *string  naming  a  single  generator*.  If you need
	      per-cpack- generator logic to control  *other*  cpack  settings,
	      then you need a CPACK_PROJECT_CONFIG_FILE.

	      The  CMake  source  tree	itself	contains  a CPACK_PROJECT_CON‐
	      FIG_FILE. See the top level file CMakeCPackOptions.cmake.in  for
	      an example.

	      If  set, the CPACK_PROJECT_CONFIG_FILE is included automatically
	      on a per-generator basis. It only need contain overrides.

	      Here's how it works:

		- cpack runs
		- it includes CPackConfig.cmake
		- it iterates over the generators listed in that file's
		  CPACK_GENERATOR list variable (unless told to use just a
		  specific one via -G on the command line...)

		- foreach generator, it then
		  - sets CPACK_GENERATOR to the one currently being iterated
		  - includes the CPACK_PROJECT_CONFIG_FILE
		  - produces the package for that generator

	      This is the key: For each generator listed in CPACK_GENERATOR in
	      CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR internally
	      to  *the	one  currently	being  used*  and  then	 include   the
	      CPACK_PROJECT_CONFIG_FILE.

	      Before  including this CPack module in your CMakeLists.txt file,
	      there are a variety of variables that can be  set	 to  customize
	      the resulting installers. The most commonly-used variables are:

		CPACK_PACKAGE_NAME - The name of the package (or application). If
		not specified, defaults to the project name.

		CPACK_PACKAGE_VENDOR - The name of the package vendor. (e.g.,
		"Kitware").

		CPACK_PACKAGE_DIRECTORY - The directory in which CPack is doing its
		packaging. If it is not set then this will default (internally) to the
		build dir. This variable may be defined in CPack config file or from
		the cpack command line option "-B". If set the command line option
		override the value found in the config file.

		CPACK_PACKAGE_VERSION_MAJOR - Package major Version

		CPACK_PACKAGE_VERSION_MINOR - Package minor Version

		CPACK_PACKAGE_VERSION_PATCH - Package patch Version

		CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
		project. Used, for example, the introduction screen of a
		CPack-generated Windows installer to describe the project.

		CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
		project (only a few words).

		CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
		not including the extension. For example, cmake-2.6.1-Linux-i686.
		The default value is

		${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.

		CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
		target system. This may be used by some CPack generators
		like NSIS to create an installation directory e.g., "CMake 2.5"
		below the installation prefix. All installed element will be
		put inside this directory.

		 CPACK_PACKAGE_ICON - A branding image that will be displayed inside
		 the installer (used by GUI installers).

		CPACK_PROJECT_CONFIG_FILE - CPack-time project CPack configuration
		file. This file included at cpack time, once per
		generator after CPack has set CPACK_GENERATOR to the actual generator
		being used. It allows per-generator setting of CPACK_* variables at
		cpack time.

		CPACK_RESOURCE_FILE_LICENSE - License to be embedded in the installer. It
		will typically be displayed to the user by the produced installer
		(often with an explicit "Accept" button, for graphical installers)
		prior to installation. This license file is NOT added to installed
		file but is used by some CPack generators like NSIS. If you want
		to install a license file (may be the same as this one)
		along with your project you must add an appropriate CMake INSTALL
		command in your CMakeLists.txt.

		CPACK_RESOURCE_FILE_README - ReadMe file to be embedded in the installer. It
		typically describes in some detail the purpose of the project
		during the installation. Not all CPack generators uses
		this file.

		CPACK_RESOURCE_FILE_WELCOME - Welcome file to be embedded in the
		installer. It welcomes users to this installer.
		Typically used in the graphical installers on Windows and Mac OS X.

		CPACK_MONOLITHIC_INSTALL - Disables the component-based
		installation mechanism. When set the component specification is ignored
		and all installed items are put in a single "MONOLITHIC" package.
		Some CPack generators do monolithic packaging by default and
		may be asked to do component packaging by setting
		CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.

		CPACK_GENERATOR - List of CPack generators to use. If not
		specified, CPack will create a set of options CPACK_BINARY_<GENNAME> (e.g.,
		CPACK_BINARY_NSIS) allowing the user to enable/disable individual
		generators. This variable may be used on the command line
		as well as in:

		  cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree

		CPACK_OUTPUT_CONFIG_FILE - The name of the CPack binary configuration
		file. This file is the CPack configuration generated by the CPack module
		for binary installers. Defaults to CPackConfig.cmake.

		CPACK_PACKAGE_EXECUTABLES - Lists each of the executables and associated
		text label to be used to create Start Menu shortcuts. For example,
		setting this to the list ccmake;CMake will
		create a shortcut named "CMake" that will execute the installed
		executable ccmake. Not all CPack generators use it (at least NSIS and
		OSXX11 do).

		CPACK_STRIP_FILES - List of files to be stripped. Starting with
		CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
		enables stripping of all files (a list of files evaluates to TRUE
		in CMake, so this change is compatible).

	      The  following  CPack variables are specific to source packages,
	      and will not affect binary packages:

		CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package. For
		example cmake-2.6.1.

		CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
		will be stripped. Starting with CMake 2.6.0
		CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
		stripping of all files (a list of files evaluates to TRUE in CMake,
		so this change is compatible).

		CPACK_SOURCE_GENERATOR - List of generators used for the source
		packages. As with CPACK_GENERATOR, if this is not specified then
		CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
		allowing users to select which packages will be generated.

		CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack source
		configuration file. This file is the CPack configuration generated by the
		CPack module for source installers. Defaults to CPackSourceConfig.cmake.

		CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
		that won't be packaged when building a source package. This is a
		list of regular expression patterns (that must be properly escaped),
		e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*

	      The following variables are for advanced uses of CPack:

		CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
		project is CMake project. Defaults to the value of CMAKE_GENERATOR
		few users will want to change this setting.

		CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
		what project to install. The four values are: Build directory,
		Project Name, Project Component, Directory. If omitted, CPack will
		build an installer that installers everything.

		CPACK_SYSTEM_NAME - System name, defaults to the value of
		${CMAKE_SYSTEM_NAME}.

		CPACK_PACKAGE_VERSION - Package full version, used internally. By
		default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
		CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.

		CPACK_TOPLEVEL_TAG - Directory for the installed files.

		CPACK_INSTALL_COMMANDS - Extra commands to install components.

		CPACK_INSTALLED_DIRECTORIES - Extra directories to install.

		 CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
		 installing this project. This is only used by installer for Windows.
		 The default value is based on the installation directory.
		 CPACK_CREATE_DESKTOP_LINKS - List of desktop links to create.

       CPackBundle
	      CPack Bundle generator (Mac OS X) specific options

	      Installers built on Mac OS X using the Bundle generator use  the
	      aforementioned  DragNDrop	 (CPACK_DMG_xxx)  variables,  plus the
	      following Bundle-specific parameters (CPACK_BUNDLE_xxx).

		CPACK_BUNDLE_NAME - The name of the generated bundle. This
		appears in the OSX finder as the bundle name. Required.

		CPACK_BUNDLE_PLIST - Path to an OSX plist file that will be used
		for the generated bundle. This assumes that the caller has generated
		or specified their own Info.plist file. Required.

		CPACK_BUNDLE_ICON - Path to an OSX icon file that will be used as
		the icon for the generated bundle. This is the icon that appears in the
		OSX finder for the bundle, and in the OSX dock when the bundle is opened.
		Required.

		CPACK_BUNDLE_STARTUP_COMMAND - Path to a startup script. This is a path to
		an executable or script that will be run whenever an end-user double-clicks
		the generated bundle in the OSX Finder. Optional.

       CPackComponent
	      Build binary and source package installers

	      The CPackComponent module is the module which handles the compo‐
	      nent  part  of  CPack.  See CPack module for general information
	      about CPack.

	      For certain kinds of binary installers (including the  graphical
	      installers  on Mac OS X and Windows), CPack generates installers
	      that allow users to select individual application components  to
	      install.	The  contents of each of the components are identified
	      by the COMPONENT argument of CMake's INSTALL command. These com‐
	      ponents  can  be annotated with user-friendly names and descrip‐
	      tions, inter-component dependencies, etc., and grouped in	 vari‐
	      ous   ways   to  customize  the  resulting  installer.  See  the
	      cpack_add_* commands,  described	below,	for  more  information
	      about component-specific installations.

	      Component-specific  installation allows users to select specific
	      sets of  components  to  install	during	the  install  process.
	      Installation components are identified by the COMPONENT argument
	      of CMake's INSTALL commands, and should be further described  by
	      the following CPack commands:

		CPACK_COMPONENTS_ALL - The list of component to install.

	      The default value of this variable is computed by CPack and con‐
	      tains all components defined by the project. The user may set it
	      to only include the specified components.

		CPACK_<GENNAME>_COMPONENT_INSTALL - Enable/Disable component install for
		CPack generator <GENNAME>.

	      Each  CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has
	      a legacy default behavior. e.g. RPM  builds  monolithic  whereas
	      NSIS  builds  component.	One can change the default behavior by
	      setting this variable to 0/1 or OFF/ON.

		CPACK_COMPONENTS_GROUPING - Specify how components are grouped for multi-package
		component-aware CPack generators.

	      Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...)  gen‐
	      erates  several  packages files when asked for component packag‐
	      ing. They group the component differently depending on the value
	      of this variable:

		- ONE_PER_GROUP (default): creates one package file per component group
		- ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component
		- IGNORE : creates one package per component, i.e. IGNORE component group

	      One can specify different grouping for different CPack generator
	      by using a CPACK_PROJECT_CONFIG_FILE.

		CPACK_COMPONENT_<compName>_DISPLAY_NAME - The name to be displayed for a component.
		CPACK_COMPONENT_<compName>_DESCRIPTION - The description of a component.
		CPACK_COMPONENT_<compName>_GROUP - The group of a component.
		CPACK_COMPONENT_<compName>_DEPENDS - The dependencies (list of components)
		on which this component depends.
		CPACK_COMPONENT_<compName>_REQUIRED - True is this component is required.

	      cpack_add_component - Describes a CPack  installation  component
	      named by the COMPONENT argument to a CMake INSTALL command.

		cpack_add_component(compname
				    [DISPLAY_NAME name]
				    [DESCRIPTION description]
				    [HIDDEN | REQUIRED | DISABLED ]
				    [GROUP group]
				    [DEPENDS comp1 comp2 ... ]
				    [INSTALL_TYPES type1 type2 ... ]
				    [DOWNLOADED]
				    [ARCHIVE_FILE filename])

	      The cmake_add_component command describes an installation compo‐
	      nent, which the user can opt to install or remove as part of the
	      graphical installation process. compname is the name of the com‐
	      ponent, as provided to the COMPONENT argument  of	 one  or  more
	      CMake INSTALL commands.

	      DISPLAY_NAME  is	the  displayed	name of the component, used in
	      graphical installers to display the component name.  This	 value
	      can be any string.

	      DESCRIPTION is an extended description of the component, used in
	      graphical installers to give  the	 user  additional  information
	      about  the component. Descriptions can span multiple lines using
	      "\n" as the line separator. Typically, these descriptions should
	      be no more than a few lines long.

	      HIDDEN  indicates	 that  this  component	will  be hidden in the
	      graphical installer, so that the	user  cannot  directly	change
	      whether it is installed or not.

	      REQUIRED	indicates  that this component is required, and there‐
	      fore will always be installed. It will be visible in the graphi‐
	      cal installer, but it cannot be unselected. (Typically, required
	      components are shown greyed out).

	      DISABLED indicates that this component should be disabled (unse‐
	      lected)  by  default.  The user is free to select this component
	      for installation, unless it is also HIDDEN.

	      DEPENDS lists the components on which this component depends. If
	      this  component  is selected, then each of the components listed
	      must also be selected. The  dependency  information  is  encoded
	      within the installer itself, so that users cannot install incon‐
	      sistent sets of components.

	      GROUP names the component group of which	this  component	 is  a
	      part. If not provided, the component will be a standalone compo‐
	      nent, not part of any  component	group.	Component  groups  are
	      described	 with  the cpack_add_component_group command, detailed
	      below.

	      INSTALL_TYPES lists the installation types of which this	compo‐
	      nent  is	a  part.  When	one  of	 these	installations types is
	      selected, this component will automatically be selected. Instal‐
	      lation  types are described with the cpack_add_install_type com‐
	      mand, detailed below.

	      DOWNLOADED indicates that this component	should	be  downloaded
	      on-the-fly  by  the  installer, rather than packaged in with the
	      installer itself. For more information,  see  the	 cpack_config‐
	      ure_downloads command.

	      ARCHIVE_FILE  provides  a	 name  for the archive file created by
	      CPack to be used for downloaded  components.  If	not  supplied,
	      CPack  will  create  a  file with some name based on CPACK_PACK‐
	      AGE_FILE_NAME and the name of the component.  See	 cpack_config‐
	      ure_downloads for more information.

	      cpack_add_component_group	 -  Describes a group of related CPack
	      installation components.

		cpack_add_component_group(groupname
					 [DISPLAY_NAME name]
					 [DESCRIPTION description]
					 [PARENT_GROUP parent]
					 [EXPANDED]
					 [BOLD_TITLE])

	      The cpack_add_component_group describes a group of  installation
	      components,  which will be placed together within the listing of
	      options.	Typically,  component  groups  allow   the   user   to
	      select/deselect  all of the components within a single group via
	      a single group-level option. Use component groups to reduce  the
	      complexity  of  installers  with	many  options. groupname is an
	      arbitrary name used to identify the group in the GROUP  argument
	      of  the  cpack_add_component  command,  which is used to place a
	      component in a group. The name of the group  must	 not  conflict
	      with the name of any component.

	      DISPLAY_NAME  is the displayed name of the component group, used
	      in graphical installers to display  the  component  group	 name.
	      This value can be any string.

	      DESCRIPTION  is  an extended description of the component group,
	      used in graphical installers to give the user additional	infor‐
	      mation  about the components within that group. Descriptions can
	      span multiple lines using "\n" as the line separator. Typically,
	      these descriptions should be no more than a few lines long.

	      PARENT_GROUP, if supplied, names the parent group of this group.
	      Parent groups are used to establish a hierarchy of groups,  pro‐
	      viding an arbitrary hierarchy of groups.

	      EXPANDED indicates that, by default, the group should show up as
	      "expanded", so that the user immediately sees all of the	compo‐
	      nents within the group. Otherwise, the group will initially show
	      up as a single entry.

	      BOLD_TITLE indicates that the group title should appear in bold,
	      to call the user's attention to the group.

	      cpack_add_install_type  - Add a new installation type containing
	      a set of predefined component selections to  the	graphical  in‐
	      staller.

		cpack_add_install_type(typename
				       [DISPLAY_NAME name])

	      The  cpack_add_install_type  command  identifies a set of prese‐
	      lected components that represents	 a  common  use	 case  for  an
	      application.  For	 example,  a  "Developer"  install  type might
	      include an application along with its header and library	files,
	      while an "End user" install type might just include the applica‐
	      tion's executable. Each component identifies itself with one  or
	      more   install   types   via   the   INSTALL_TYPES  argument  to
	      cpack_add_component.

	      DISPLAY_NAME is the displayed name of the	 install  type,	 which
	      will typically show up in a drop-down box within a graphical in‐
	      staller. This value can be any string.

	      cpack_configure_downloads - Configure CPack to download selected
	      components on-the-fly as part of the installation process.

		cpack_configure_downloads(site
					  [UPLOAD_DIRECTORY dirname]
					  [ALL]
					  [ADD_REMOVE|NO_ADD_REMOVE])

	      The   cpack_configure_downloads	command	 configures  installa‐
	      tion-time downloads of selected components. For  each  download‐
	      able component, CPack will create an archive containing the con‐
	      tents of that component, which should be uploaded to  the	 given
	      site. When the user selects that component for installation, the
	      installer will download and extract the component in place. This
	      feature  is useful for creating small installers that only down‐
	      load the requested components, saving  bandwidth.	 Additionally,
	      the  installers  are small enough that they will be installed as
	      part of the normal installation process, and the "Change" button
	      in  Windows  Add/Remove Programs control panel will allow one to
	      add or remove  parts  of	the  application  after	 the  original
	      installation.  On Windows, the downloaded-components functional‐
	      ity requires the ZipDLL plug-in for NSIS, available at:

		http://nsis.sourceforge.net/ZipDLL_plug-in

	      On Mac OS X, installers that download components on-the-fly  can
	      only  be	built  and  installed on system using Mac OS X 10.5 or
	      later.

	      The site argument is a URL where the archives  for  downloadable
	      components	     will	      reside,		 e.g.,
	      http://www.cmake.org/files/2.6.1/installer/ All of the  archives
	      produced by CPack should be uploaded to that location.

	      UPLOAD_DIRECTORY	is the local directory where CPack will create
	      the various archives for each of the components. The contents of
	      this  directory  should  be uploaded to a location accessible by
	      the URL given in the site argument. If omitted, CPack  will  use
	      the  directory CPackUploads inside the CMake binary directory to
	      store the generated archives.

	      The ALL flag indicates that all components be downloaded. Other‐
	      wise,  only  those components explicitly marked as DOWNLOADED or
	      that have a specified ARCHIVE_FILE will be downloaded. Addition‐
	      ally, the ALL option implies ADD_REMOVE (unless NO_ADD_REMOVE is
	      specified).

	      ADD_REMOVE indicates that CPack should install a copy of the in‐
	      staller  that  can  be  called from Windows' Add/Remove Programs
	      dialog (via the "Modify" button) to change the set of  installed
	      components.  NO_ADD_REMOVE  turns off this behavior. This option
	      is ignored on Mac OS X.

       CPackCygwin

		through OSA-script) using a normal folder from which the .DS_Store
		file can then be extracted.

		CPACK_DMG_BACKGROUND_IMAGE - Path to a background image file. This
		file will be used as the background for the Finder Window when the disk
		image is opened.  By default no background image is set. The background
		image is applied after applying the custom .DS_Store file.

		CPACK_COMMAND_HDIUTIL - Path to the hdiutil(1) command used to
		operate on disk image files on Mac OS X. This variable can be used
		to override the automatically detected command (or specify its

		CPACK_COMMAND_REZ - Path to the Rez(1) command used to compile
		resources on Mac OS X. This variable can be used to override the
		automatically detected command (or specify its location if the
		auto-detection fails to find it.)

       CPackDeb
	      The builtin (binary) CPack Deb generator (Unix only)

	      CPackDeb may be used to create Deb package using CPack. CPackDeb
	      is  a  CPack generator thus it uses the CPACK_XXX variables used
	      by CPack	:  http://www.cmake.org/Wiki/CMake:CPackConfiguration.
	      CPackDeb	generator  should  work	 on any linux host but it will
	      produce better deb package when Debian specific tools 'dpkg-xxx'
	      are usable on the build system.

	      CPackDeb	has  specific  features	 which	are  controlled by the
	      specifics	 CPACK_DEBIAN_XXX  variables.You'll  find  a  detailed

		variable to some value (e.g., 10.4) only if you want to guarantee
		that your installer will work on that version of Mac OS X, and
		don't mind missing extra features available in the installer
		shipping with later versions of Mac OS X.

       CPackRPM
	      The builtin (binary) CPack RPM generator (Unix only)

	      CPackRPM may be used to create RPM package using CPack. CPackRPM
	      is  a  CPack generator thus it uses the CPACK_XXX variables used
	      by CPack : http://www.cmake.org/Wiki/CMake:CPackConfiguration

	      However CPackRPM has specific features which are	controlled  by
	      the  specifics  CPACK_RPM_XXX variables. CPackRPM is a component
	      aware generator so when CPACK_RPM_COMPONENT_INSTALL is  ON  some
	      more  CPACK_RPM_<ComponentName>_XXXX  variables  may  be used in
	      order to have component specific values. Note however that <com‐
	      ponentName>  refers to the **grouping name**. This may be either
	      a component name or a component GROUP name. Usually  those  vars
	      correspond  to  RPM spec file entities, one may find information
	      about spec files here http://www.rpm.org/wiki/Docs. You'll  find
	      a detailed usage of CPackRPM on the wiki:

		http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29

		   This may be set to "noarch" if you
		   know you are building a noarch package.
		CPACK_RPM_PACKAGE_RELEASE - The RPM package release.
		   Mandatory : YES
		   Default   : 1
		   This is the numbering of the RPM package
		   itself, i.e. the version of the packaging and not the version of the
		   content (see CPACK_RPM_PACKAGE_VERSION). One may change the default
		   value if the previous packaging was buggy and/or you want to put here
		   a fancy Linux distro specific numbering.
		CPACK_RPM_PACKAGE_LICENSE - The RPM package license policy.
		   Mandatory : YES
		   Default   : "unknown"
		CPACK_RPM_PACKAGE_GROUP - The RPM package group.
		   Mandatory : YES

		   Default   : -
		   May be used to override RPM compression type to be used
		   to build the RPM. For example some Linux distribution now default
		   to lzma or xz compression whereas older cannot use such RPM.
		   Using this one can enforce compression type to be used.
		   Possible value are: lzma, xz, bzip2 and gzip.
		CPACK_RPM_PACKAGE_REQUIRES - RPM spec requires field.
		   Mandatory : NO
		   Default   : -
		   May be used to set RPM dependencies (requires).
		   Note that you must enclose the complete requires string between quotes,
		   for example:
		   set(CPACK_RPM_PACKAGE_REQUIRES "python >= 2.5.0, cmake >= 2.8")
		   The required package list of an RPM file could be printed with
		   rpm -qp --requires file.rpm
		CPACK_RPM_PACKAGE_SUGGESTS - RPM spec suggest field.
		   Mandatory : NO
		   Default   : -
		   May be used to set weak RPM dependencies (suggests).
		   Note that you must enclose the complete requires string between quotes.
		CPACK_RPM_PACKAGE_PROVIDES - RPM spec provides field.
		   Mandatory : NO
		   Default   : -
		   May be used to set RPM dependencies (provides).

		CPACK_RPM_PACKAGE_OBSOLETES - RPM spec obsoletes field.
		   Mandatory : NO
		   Default   : -
		   May be used to set RPM packages that are obsoleted by this one.
		CPACK_RPM_PACKAGE_RELOCATABLE - build a relocatable RPM.
		   Mandatory : NO
		   Default   : CPACK_PACKAGE_RELOCATABLE
		   If this variable is set to TRUE or ON CPackRPM will try
		   to build a relocatable RPM package. A relocatable RPM may
		   be installed using rpm --prefix or --relocate in order to
		   install it at an alternate place see rpm(8).
		   Note that currently this may fail if CPACK_SET_DESTDIR is set to ON.
		   If CPACK_SET_DESTDIR is set then you will get a warning message
		   but if there is file installed with absolute path you'll get
		   unexpected behavior.
		CPACK_RPM_SPEC_INSTALL_POST - [deprecated].
		   Mandatory : NO
		   Default   : -
		   This way of specifying post-install script is deprecated use
		   CPACK_RPM_POST_INSTALL_SCRIPT_FILE
		   May be used to set an RPM post-install command inside the spec file.
		   For example setting it to "/bin/true" may be used to prevent
		   rpmbuild to strip binaries.
		CPACK_RPM_SPEC_MORE_DEFINE - RPM extended spec definitions lines.
		   Mandatory : NO
		   Default   : -
		   May be used to add any %define lines to the generated spec file.
		CPACK_RPM_PACKAGE_DEBUG - Toggle CPackRPM debug output.
		   Mandatory : NO
		   Default   : -
		   May be set when invoking cpack in order to trace debug information
		   during CPack RPM run. For example you may launch CPack like this
		   cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM
		CPACK_RPM_USER_BINARY_SPECFILE - A user provided spec file.
		   Mandatory : NO
		   Default   : -
		   May be set by the user in order to specify a USER binary spec file
		   to be used by CPackRPM instead of generating the file.
		   The specified file will be processed by configure_file( @ONLY).
		   One can provide a component specific file by setting
		   CPACK_RPM_<componentName>_USER_BINARY_SPECFILE.
		CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE - Spec file template.
		   Mandatory : NO
		   Default   : -
		   If set CPack will generate a template for USER specified binary
		   spec file and stop with an error. For example launch CPack like this
		   cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM
		   The user may then use this file in order to hand-craft is own
		   binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.
		CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
		CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
		   Mandatory : NO
		   Default   : -
		   May be used to embed a pre (un)installation script in the spec file.
		   The refered script file(s) will be read and directly
		   put after the %pre or %preun section
		   If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
		   each component can be overridden with
		   CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE and
		   CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE
		   One may verify which scriptlet has been included with
		    rpm -qp --scripts  package.rpm
		CPACK_RPM_POST_INSTALL_SCRIPT_FILE
		CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
		   Mandatory : NO
		   Default   : -
		   May be used to embed a post (un)installation script in the spec file.
		   The refered script file(s) will be read and directly
		   put after the %post or %postun section
		   If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
		   each component can be overridden with
		   CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and
		   CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE
		   One may verify which scriptlet has been included with
		    rpm -qp --scripts  package.rpm
		CPACK_RPM_USER_FILELIST
		CPACK_RPM_<COMPONENT>_USER_FILELIST
		   Mandatory : NO
		   Default   : -
		   May be used to explicitly specify %(<directive>) file line
		   in the spec file. Like %config(noreplace) or any other directive
		   that be found in the %files section. Since CPackRPM is generating
		   the list of files (and directories) the user specified files of
		   the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list.
		CPACK_RPM_CHANGELOG_FILE - RPM changelog file.
		   Mandatory : NO
		   Default   : -
		   May be used to embed a changelog in the spec file.
		   The refered file will be read and directly put after the %changelog

		CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST - list of path to be excluded.
		   Mandatory : NO
		   Default   : /etc /etc/init.d /usr /usr/share /usr/share/doc /usr/bin /usr/lib /usr/lib64 /usr/include
		   May be used to exclude path (directories or files) from the auto-generated
		   list of paths discovered by CPack RPM. The defaut value contains a reasonable
		   set of values if the variable is not defined by the user. If the variable
		   is defined by the user then CPackRPM will NOT any of the default path.
		   If you want to add some path to the default list then you can use
		   CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION variable.
		CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION - additional list of path to be excluded.
		   Mandatory : NO
		   Default   : -
		   May be used to add more exclude path (directories or files) from the initial
		   default list of excluded paths. See CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST.

       CPackWIX
	      CPack WiX generator specific options

	      The following variables are specific to the installers built  on
	      Windows using WiX.

		CPACK_WIX_UPGRADE_GUID - Upgrade GUID (Product/@UpgradeCode)

	      Will be automatically generated unless explicitly provided.

	      It  should  be  explicitly set to a constant generated gloabally
	      unique identifier (GUID) to allow	 your  installers  to  replace
	      existing installations that use the same GUID.

	      You  may for example explicitly set this variable in your CMake‐
	      Lists.txt to the value that has been generated per default.  You
	      should not use GUIDs that you did not generate yourself or which
	      may belong to other projects.

	      A	 GUID  shall  have  the	  following   fixed   length   syntax:
	      XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

		(each X represents an uppercase hexadecimal digit)
		CPACK_WIX_PRODUCT_GUID - Product GUID (Product/@Id)

	      Will be automatically generated unless explicitly provided.

	      If  explicitly provided this will set the Product Id of your in‐
	      staller.

	      The installer will abort if it detects a pre-existing  installa‐
	      tion that uses the same GUID.

	      The    GUID    shall    use    the    syntax    described	   for
	      CPACK_WIX_UPGRADE_GUID.

		CPACK_WIX_LICENSE_RTF - RTF License File

	      If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is  used
	      as-is.

	      If  CPACK_RESOURCE_FILE_LICENSE  has  an	.txt  extension	 it is
	      implicitly converted to RTF by the WiX Generator.

	      With CPACK_WIX_LICENSE_RTF you can  override  the	 license  file
	      used by the WiX Generator in case CPACK_RESOURCE_FILE_LICENSE is
	      in an unsupported format or the .txt -> .rtf conversion does not
	      work as expected.

	      CPACK_WIX_PRODUCT_ICON - The Icon shown next to the program name
	      in Add/Remove programs.

	      If set, this icon is used in place of the default icon.

	      CPACK_WIX_UI_BANNER - The bitmap will appear at the top  of  all
	      installer pages other than the welcome and completion dialogs.

	      If set, this image will replace the default banner image.

	      This image must be 493 by 58 pixels.

	      CPACK_WIX_UI_DIALOG  - Background bitmap used on the welcome and
	      completion dialogs.

	      If this variable is set, the installer will replace the  default
	      dialog image.

	      This image must be 493 by 312 pixels.

	      CPACK_WIX_PROGRAM_MENU_FOLDER  -	Start  menu  folder  name  for
	      launcher.

	      If this variable	is  not	 set,  it  will	 be  initialized  with
	      CPACK_PACKAGE_NAME

	      CPACK_WIX_CULTURES - Language(s) of the installer

	      Languages	 are compiled into the WixUI extension library. To use
	      them, simply provide the name of the culture.   If  you  specify
	      more  than one culture identifier in a comma or semicolon delim‐
	      ited list, the first one that is found will be  used.   You  can
	      find  a  list  of	 supported  languages  at:  http://wix.source‐
	      forge.net/manual-wix3/WixUI_localization.htm

	      CPACK_WIX_TEMPLATE - Template file for WiX generation

	      If this variable is set, the specified template will be used  to
	      generate	the  WiX wxs file. This should be used if further cus‐
	      tomization of the output is required.

	      If this variable is not set, the default MSI  template  included
	      with CMake will be used.

       CTest  Configure a project for testing with CTest/CDash

	      Include  this module in the top CMakeLists.txt file of a project
	      to enable testing with CTest and dashboard submissions to CDash:

		 project(MyProject)
		 ...
		 include(CTest)

	      The module automatically creates	a  BUILD_TESTING  option  that
	      selects  whether	to  enable  testing  support  (ON by default).
	      After including the module, use code like

		 if(BUILD_TESTING)
		   # ... CMake code to create tests ...
		 endif()

	      to creating tests when testing is enabled.

	      To enable submissions to a  CDash	 server,  create  a  CTestCon‐
	      fig.cmake file at the top of the project with content such as

		 set(CTEST_PROJECT_NAME "MyProject")
		 set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
		 set(CTEST_DROP_METHOD "http")
		 set(CTEST_DROP_SITE "my.cdash.org")
		 set(CTEST_DROP_LOCATION "/submit.php?project=MyProject")
		 set(CTEST_DROP_SITE_CDASH TRUE)

	      (the  CDash server can provide the file to a project administra‐
	      tor who configures 'MyProject'). Settings in the config file are
	      shared  by  both	this  CTest  module and the CTest command-line
	      tool's dashboard script mode (ctest -S).

	      While building a project for submission to  CDash,  CTest	 scans
	      the  build  output for errors and warnings and reports them with
	      surrounding context from the build log.  This  generic  approach
	      works  for  all build tools, but does not give details about the
	      command invocation that produced a given problem.	 One  may  get
	      more detailed reports by adding

		 set(CTEST_USE_LAUNCHERS 1)

	      to the CTestConfig.cmake file.  When this option is enabled, the
	      CTest module tells CMake's Makefile generators to	 invoke	 every
	      command  in  the generated build system through a CTest launcher
	      program.	(Currently the CTEST_USE_LAUNCHERS option  is  ignored
	      on   non-Makefile	 generators.)	During	a  manual  build  each
	      launcher transparently runs the  command	it  wraps.   During  a
	      CTest-driven build for submission to CDash each launcher reports
	      detailed information when its command fails or  warns.  (Setting
	      CTEST_USE_LAUNCHERS in CTestConfig.cmake is convenient, but also
	      adds the launcher overhead even  for  manual  builds.   One  may
	      instead  set  it	in  a CTest dashboard script and add it to the
	      CMake cache for the build tree.)

       CTestScriptMode

	      This file is read by ctest in script mode (-S)

       CTestUseLaunchers
	      Set the RULE_LAUNCH_* global properties when CTEST_USE_LAUNCHERS
	      is on.

	      CTestUseLaunchers	   is	 automatically	 included   when   you
	      include(CTest). However, it is split out	into  its  own	module
	      file  so	projects can use the CTEST_USE_LAUNCHERS functionality
	      independently.

	      To use launchers, set CTEST_USE_LAUNCHERS to ON in  a  ctest  -S
	      dashboard	 script, and then also set it in the cache of the con‐
	      figured project. Both cmake and ctest need to know the value  of
	      it  for  the  launchers to work properly. CMake needs to know in
	      order to generate proper build rules, and	 ctest,	 in  order  to
	      produce the proper error and warning analysis.

	      For  convenience, you may set the ENV variable CTEST_USE_LAUNCH‐
	      ERS_DEFAULT in your ctest -S script, too. Then, as long as  your
	      CMakeLists uses include(CTest) or include(CTestUseLaunchers), it
	      will  use	 the  value  of	 the  ENV  variable  to	 initialize  a
	      CTEST_USE_LAUNCHERS cache variable. This cache variable initial‐
	      ization  only  occurs  if	 CTEST_USE_LAUNCHERS  is  not  already
	      defined.

       CheckCCompilerFlag
	      Check whether the C compiler supports a given flag.

	      CHECK_C_COMPILER_FLAG(<flag> <var>)

		<flag> - the compiler flag
		<var>  - variable to store the result

	      This internally calls the check_c_source_compiles macro and sets
	      CMAKE_REQUIRED_DEFINITIONS to <flag>. See help for CheckCSource‐
	      Compiles	for  a	listing of variables that can otherwise modify
	      the build. The result only tells that the compiler does not give
	      an  error	 message  when it encounters the flag. If the flag has
	      any effect or even a specific one is beyond the  scope  of  this
	      module.

       CheckCSourceCompiles
	      Check if given C source compiles and links into an executable

	      CHECK_C_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])

		<code>	     - source code to try to compile, must define 'main'
		<var>	     - variable to store whether the source code compiled
		<fail-regex> - fail if test output matches this regex

	      The  following variables may be set before calling this macro to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckCSourceRuns
	      Check if the given C source code compiles and runs.

	      CHECK_C_SOURCE_RUNS(<code> <var>)

		<code>	 - source code to try to compile
		<var>	 - variable to store the result
			   (1 for success, empty for failure)

	      The following variables may be set before calling this macro  to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckCXXCompilerFlag
	      Check whether the CXX compiler supports a given flag.

	      CHECK_CXX_COMPILER_FLAG(<flag> <var>)

		<flag> - the compiler flag
		<var>  - variable to store the result

	      This  internally	calls  the check_cxx_source_compiles macro and
	      sets CMAKE_REQUIRED_DEFINITIONS to <flag>. See help  for	Check‐
	      CXXSourceCompiles	 for a listing of variables that can otherwise
	      modify the build. The result only tells that the	compiler  does
	      not  give	 an  error message when it encounters the flag. If the
	      flag has any effect or even a specific one is beyond  the	 scope
	      of this module.

       CheckCXXSourceCompiles
	      Check if given C++ source compiles and links into an executable

	      CHECK_CXX_SOURCE_COMPILES(<code>	      <var>	   [FAIL_REGEX
	      <fail-regex>])

		<code>	     - source code to try to compile, must define 'main'
		<var>	     - variable to store whether the source code compiled
		<fail-regex> - fail if test output matches this regex

	      The following variables may be set before calling this macro  to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckCXXSourceRuns
	      Check if the given C++ source code compiles and runs.

	      CHECK_CXX_SOURCE_RUNS(<code> <var>)

		<code>	 - source code to try to compile
		<var>	 - variable to store the result
			   (1 for success, empty for failure)

	      The  following variables may be set before calling this macro to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckCXXSymbolExists
	      Check if a symbol exists as a function, variable,	 or  macro  in
	      C++

	      CHECK_CXX_SYMBOL_EXISTS(<symbol> <files> <variable>)

	      Check  that  the	<symbol>  is  available	 after including given
	      header <files> and store the result in  a	 <variable>.   Specify
	      the list of files in one argument as a semicolon-separated list.
	      CHECK_CXX_SYMBOL_EXISTS() can be used to check in C++ files,  as
	      opposed to CHECK_SYMBOL_EXISTS(), which works only for C.

	      If  the  header files define the symbol as a macro it is consid‐
	      ered available and assumed to work.  If the header files declare
	      the  symbol  as a function or variable then the symbol must also
	      be available for linking.	 If the symbol is a type or enum value
	      it  will	not  be	 recognized  (consider	using CheckTypeSize or
	      CheckCSourceCompiles).

	      The following variables may be set before calling this macro  to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckFortranFunctionExists
	      macro which checks if the Fortran function exists

	      CHECK_FORTRAN_FUNCTION_EXISTS(FUNCTION VARIABLE)

		FUNCTION - the name of the Fortran function
		VARIABLE - variable to store the result

	      The  following variables may be set before calling this macro to
	      modify the way the check is run:

		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckFunctionExists
	      Check if a C function can be linked

	      CHECK_FUNCTION_EXISTS(<function> <variable>)

	      Check that the <function> is provided by libraries on the system
	      and store the result in a <variable>.  This does not verify that
	      any system header file declares the function, only that  it  can
	      be found at link time (consider using CheckSymbolExists).

	      The  following variables may be set before calling this macro to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckIncludeFile
	      macro which checks the include file exists.

	      CHECK_INCLUDE_FILE(INCLUDE VARIABLE)

		INCLUDE	 - name of include file
		VARIABLE - variable to return result

	      an optional third argument is the CFlags to add to  the  compile
	      line or you can use CMAKE_REQUIRED_FLAGS

	      The  following variables may be set before calling this macro to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories

       CheckIncludeFileCXX
	      Check if the include file exists.

		CHECK_INCLUDE_FILE_CXX(INCLUDE VARIABLE)

		INCLUDE	 - name of include file
		VARIABLE - variable to return result

	      An optional third argument is the CFlags to add to  the  compile
	      line or you can use CMAKE_REQUIRED_FLAGS.

	      The  following variables may be set before calling this macro to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories

       CheckIncludeFiles
	      Check if the files can be included

	      CHECK_INCLUDE_FILES(INCLUDE VARIABLE)

		INCLUDE	 - list of files to include
		VARIABLE - variable to return result

	      The following variables may be set before calling this macro  to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories

       CheckLanguage
	      Check if a language can be enabled

	      Usage:

		check_language(<lang>)

	      where  <lang>  is	 a  language that may be passed to enable_lan‐
	      guage() such as "Fortran".  If CMAKE_<lang>_COMPILER is  already
	      defined the check does nothing.  Otherwise it tries enabling the
	      language	in  a  test  project.	The  result   is   cached   in
	      CMAKE_<lang>_COMPILER  as	 the  compiler that was found, or NOT‐
	      FOUND if the language cannot be enabled.

	      Example:

		check_language(Fortran)
		if(CMAKE_Fortran_COMPILER)
		  enable_language(Fortran)
		else()
		  message(STATUS "No Fortran support")
		endif()

       CheckLibraryExists
	      Check if the function exists.

	      CHECK_LIBRARY_EXISTS (LIBRARY FUNCTION LOCATION VARIABLE)

		LIBRARY	 - the name of the library you are looking for
		FUNCTION - the name of the function
		LOCATION - location where the library should be found
		VARIABLE - variable to store the result

	      The following variables may be set before calling this macro  to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckPrototypeDefinition
	      Check if the protoype we expect is correct.

	      check_prototype_definition(FUNCTION   PROTOTYPE	RETURN	HEADER
	      VARIABLE)

		FUNCTION - The name of the function (used to check if prototype exists)
		PROTOTYPE- The prototype to check.
		RETURN - The return value of the function.
		HEADER - The header files required.
		VARIABLE - The variable to store the result.

	      Example:

		check_prototype_definition(getpwent_r
		 "struct passwd *getpwent_r(struct passwd *src, char *buf, int buflen)"
		 "NULL"
		 "unistd.h;pwd.h"
		 SOLARIS_GETPWENT_R)

	      The following variables may be set before calling this macro  to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckStructHasMember
	      Check  if	 the  given  struct  or class has the specified member
	      variable

	      CHECK_STRUCT_HAS_MEMBER (STRUCT MEMBER HEADER VARIABLE)

		STRUCT - the name of the struct or class you are interested in
		MEMBER - the member which existence you want to check
		HEADER - the header(s) where the prototype should be declared
		VARIABLE - variable to store the result

	      The following variables may be set before calling this macro  to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories

	      Example:	  CHECK_STRUCT_HAS_MEMBER("struct    timeval"	tv_sec
	      sys/select.h HAVE_TIMEVAL_TV_SEC)

       CheckSymbolExists
	      Check if a symbol exists as a function, variable, or macro

	      CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>)

	      Check that the  <symbol>	is  available  after  including	 given
	      header  <files>  and  store the result in a <variable>.  Specify
	      the list of files in one argument as a semicolon-separated list.

	      If the header files define the symbol as a macro it  is  consid‐
	      ered available and assumed to work.  If the header files declare
	      the symbol as a function or variable then the symbol  must  also
	      be available for linking.	 If the symbol is a type or enum value
	      it will not  be  recognized  (consider  using  CheckTypeSize  or
	      CheckCSourceCompiles).  If  the  check  needs to be done in C++,
	      consider using CHECK_CXX_SYMBOL_EXISTS(), which does the same as
	      CHECK_SYMBOL_EXISTS(), but in C++.

	      The  following variables may be set before calling this macro to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

       CheckTypeSize
	      Check sizeof a type

		CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY])

	      Check if the type exists and  determine  its  size.  On  return,
	      "HAVE_${VARIABLE}" holds the existence of the type, and "${VARI‐
	      ABLE}" holds one of the following:

		 <size> = type has non-zero size <size>
		 "0"	= type has arch-dependent size (see below)
		 ""	= type does not exist

	      Furthermore, the variable "${VARIABLE}_CODE" holds C  preproces‐
	      sor  code	 to  define the macro "${VARIABLE}" to the size of the
	      type, or leave the macro undefined if the type does not exist.

	      The variable "${VARIABLE}" may be "0"  when  CMAKE_OSX_ARCHITEC‐
	      TURES  has  multiple  architectures  for building OS X universal
	      binaries. This indicates that the type size varies across archi‐
	      tectures.	 In this case "${VARIABLE}_CODE" contains C preproces‐
	      sor tests mapping from each architecture	macro  to  the	corre‐
	      sponding type size. The list of architecture macros is stored in
	      "${VARIABLE}_KEYS", and the value for  each  key	is  stored  in
	      "${VARIABLE}-${KEY}".

	      If  the BUILTIN_TYPES_ONLY option is not given, the macro checks
	      for headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves
	      results  in  HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H.
	      The type size check automatically includes the  available	 head‐
	      ers, thus supporting checks of types defined in the headers.

	      Despite  the  name of the macro you may use it to check the size
	      of more complex expressions, too. To check e.g. for the size  of
	      a struct member you can do something like this:

		check_type_size("((struct something*)0)->member" SIZEOF_MEMBER)

	      The  following variables may be set before calling this macro to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_INCLUDES = list of include directories
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link
		CMAKE_EXTRA_INCLUDE_FILES = list of extra headers to include

       CheckVariableExists
	      Check if the variable exists.

		CHECK_VARIABLE_EXISTS(VAR VARIABLE)

		VAR	 - the name of the variable
		VARIABLE - variable to store the result

	      This macro is only for C variables.

	      The following variables may be set before calling this macro  to
	      modify the way the check is run:

		CMAKE_REQUIRED_FLAGS = string of compile command line flags
		CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
		CMAKE_REQUIRED_LIBRARIES = list of libraries to link

	      This file is the backwards-compatibility version	of  the	 CTest
	      module.  It supports using the old Dart 1 Tcl client for driving
	      dashboard submissions as well as testing with CTest.  This  mod‐
	      ule  should be included in the CMakeLists.txt file at the top of
	      a project.  Typical usage:

		include(Dart)
		if(BUILD_TESTING)
		  # ... testing related CMake code ...
		endif()

	      The BUILD_TESTING option is created by the Dart module to deter‐
	      mine  whether testing support should be enabled.	The default is
	      ON.

       DeployQt4
	      Functions to help assemble a standalone Qt4 executable.

	      A collection of CMake utility functions useful for deploying Qt4
	      executables.

	      The following functions are provided by this module:

		 write_qt4_conf
		 resolve_qt4_paths
		 fixup_qt4_executable
		 install_qt4_plugin_path
		 install_qt4_plugin
		 install_qt4_executable

	      Requires	CMake 2.6 or greater because it uses function and PAR‐
	      ENT_SCOPE. Also depends on BundleUtilities.cmake.

		WRITE_QT4_CONF(<qt_conf_dir> <qt_conf_contents>)

	      Writes  a	 qt.conf  file	with   the   <qt_conf_contents>	  into
	      <qt_conf_dir>.

		RESOLVE_QT4_PATHS(<paths_var> [<executable_path>])

	      Loop  through  <paths_var>  list	and if any don't exist resolve
	      them relative to the  <executable_path>  (if  supplied)  or  the
	      CMAKE_INSTALL_PREFIX.

		FIXUP_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf>])

	      Copies  Qt  plugins,  writes a Qt configuration file (if needed)
	      and fixes up a Qt4 executable using  BundleUtilities  so	it  is
	      standalone and can be drag-and-drop copied to another machine as
	      long as all of the system libraries are compatible.

	      <executable> should point to the executable to be fixed-up.

	      <qtplugins> should contain a list of the names or paths  of  any
	      Qt plugins to be installed.

	      <libs> will be passed to BundleUtilities and should be a list of
	      any already installed plugins, libraries or executables to  also
	      be fixed-up.

	      <dirs>  will be passed to BundleUtilities and should contain and
	      directories to be searched to find library dependencies.

	      <plugins_dir> allows an custom plugins directory to be used.

	      <request_qt_conf> will force a qt.conf file to be	 written  even
	      if not needed.

		INSTALL_QT4_PLUGIN_PATH(plugin executable copy installed_plugin_path_var <plugins_dir> <component> <configurations>)

	      Install  (or  copy)  a  resolved <plugin> to the default plugins
	      directory (or <plugins_dir>) relative to <executable> and	 store
	      the result in <installed_plugin_path_var>.

	      If  <copy> is set to TRUE then the plugins will be copied rather
	      than installed. This is to allow this module to be used at CMake
	      time rather than install time.

	      If <component> is set then anything installed will use this COM‐
	      PONENT.

		INSTALL_QT4_PLUGIN(plugin executable copy installed_plugin_path_var <plugins_dir> <component>)

	      Install (or copy) an unresolved <plugin> to the default  plugins
	      directory	 (or <plugins_dir>) relative to <executable> and store
	      the result in <installed_plugin_path_var>. See documentation  of
	      INSTALL_QT4_PLUGIN_PATH.

		INSTALL_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf> <component>])

	      Installs	Qt plugins, writes a Qt configuration file (if needed)
	      and fixes up a Qt4 executable using  BundleUtilities  so	it  is
	      standalone and can be drag-and-drop copied to another machine as
	      long as all of the system libraries  are	compatible.  The  exe‐
	      cutable  will  be	 fixed-up  at install time. <component> is the
	      COMPONENT used for bundle fixup  and  plugin  installation.  See
	      documentation of FIXUP_QT4_BUNDLE.

       Documentation
	      DocumentationVTK.cmake

	      This  file provides support for the VTK documentation framework.
	      It relies on several tools (Doxygen, Perl, etc).

       ExternalData
	      Manage data files stored outside source tree

	      Use this module to unambiguously	reference  data	 files	stored
	      outside  the source tree and fetch them at build time from arbi‐
	      trary local and remote content-addressed	locations.   Functions
	      provided	by  this  module  recognize  arguments with the syntax
	      "DATA{<name>}" as references to external data, replace them with
	      full paths to local copies of those data, and create build rules
	      to fetch and update the local copies.

	      The DATA{} syntax is literal and the <name> is a full  or	 rela‐
	      tive  path within the source tree.  The source tree must contain
	      either a real data  file	at  <name>  or	a  "content  link"  at
	      <name><ext>  containing  a  hash	of  the real file using a hash
	      algorithm corresponding to <ext>.	  For  example,	 the  argument
	      "DATA{img.png}" may be satisfied by either a real "img.png" file
	      in the current source directory or a "img.png.md5" file contain‐
	      ing its MD5 sum.

	      The  'ExternalData_Expand_Arguments'  function  evaluates DATA{}
	      references in its arguments and constructs a new list  of	 argu‐
	      ments:

		ExternalData_Expand_Arguments(
		  <target>   # Name of data management target
		  <outVar>   # Output variable
		  [args...]  # Input arguments, DATA{} allowed
		  )

	      It  replaces  each DATA{} reference in an argument with the full
	      path of a real data file on disk that will exist after the <tar‐
	      get> builds.

	      The  'ExternalData_Add_Test'  function  wraps  around  the CMake
	      add_test() command but supports DATA{} references in  its	 argu‐
	      ments:

		ExternalData_Add_Test(
		  <target>   # Name of data management target
		  ...	     # Arguments of add_test(), DATA{} allowed
		  )

	      It  passes  its  arguments through ExternalData_Expand_Arguments
	      and then invokes add_test() using the results.

	      The 'ExternalData_Add_Target' function creates a	custom	target
	      to manage local instances of data files stored externally:

		ExternalData_Add_Target(
		  <target>   # Name of data management target
		  )

	      It  creates  custom  commands in the target as necessary to make
	      data files available for each DATA{} reference previously evalu‐
	      ated  by other functions provided by this module.	 A list of URL
	      templates must be provided in the variable ExternalData_URL_TEM‐
	      PLATES  using  the  placeholders "%(algo)" and "%(hash)" in each
	      template.	 Data fetch rules try each URL template	 in  order  by
	      substituting  the hash algorithm name for "%(algo)" and the hash
	      value for "%(hash)".

	      The following hash algorithms are supported:

		  %(algo)     <ext>	Description
		  -------     -----	-----------
		  MD5	      .md5	Message-Digest Algorithm 5, RFC 1321
		  SHA1	      .sha1	US Secure Hash Algorithm 1, RFC 3174
		  SHA224      .sha224	US Secure Hash Algorithms, RFC 4634
		  SHA256      .sha256	US Secure Hash Algorithms, RFC 4634
		  SHA384      .sha384	US Secure Hash Algorithms, RFC 4634
		  SHA512      .sha512	US Secure Hash Algorithms, RFC 4634

	      Note that the hashes are used only for unique  data  identifica‐
	      tion and download verification.  This is not security software.

	      Example usage:

		 include(ExternalData)
		 set(ExternalData_URL_TEMPLATES "file:///local/%(algo)/%(hash)"
						"http://data.org/%(algo)/%(hash)")
		 ExternalData_Add_Test(MyData
		   NAME MyTest
		   COMMAND MyExe DATA{MyInput.png}
		   )
		 ExternalData_Add_Target(MyData)

	      When test "MyTest" runs the "DATA{MyInput.png}" argument will be
	      replaced by the full path to a real instance of  the  data  file
	      "MyInput.png"  on	 disk.	 If the source tree contains a content
	      link such as "MyInput.png.md5" then the "MyData" target  creates
	      a real "MyInput.png" in the build tree.

	      The  DATA{}  syntax can be told to fetch a file series using the
	      form "DATA{<name>,:}", where the ":" is literal.	If the	source
	      tree  contains  a	 group	of files or content links named like a
	      series then a reference to one member adds rules to fetch all of
	      them.   Although	all  members of a series are fetched, only the
	      file originally named by the DATA{} argument is substituted  for
	      it.  The default configuration recognizes file series names end‐
	      ing with "#.ext", "_#.ext", ".#.ext", or "-#.ext" where "#" is a
	      sequence	of  decimal digits and ".ext" is any single extension.
	      Configure it with a regex	 that  parses  <number>	 and  <suffix>
	      parts from the end of <name>:

		ExternalData_SERIES_PARSE = regex of the form (<number>)(<suffix>)$

	      For more complicated cases set:

		ExternalData_SERIES_PARSE = regex with at least two () groups
		ExternalData_SERIES_PARSE_PREFIX = <prefix> regex group number, if any
		ExternalData_SERIES_PARSE_NUMBER = <number> regex group number
		ExternalData_SERIES_PARSE_SUFFIX = <suffix> regex group number

	      Configure	 series	 number matching with a regex that matches the
	      <number> part of series members named <prefix><number><suffix>:

		ExternalData_SERIES_MATCH = regex matching <number> in all series members

	      Note that the <suffix> of a series does not include a hash-algo‐
	      rithm extension.

	      The  DATA{} syntax can alternatively match files associated with
	      the named file and contained in the same directory.   Associated
	      files   may   be	 specified   by	  options   using  the	syntax
	      DATA{<name>,<opt1>,<opt2>,...}.  Each  option  may  specify  one
	      file by name or specify a regular expression to match file names
	      using the syntax REGEX:<regex>.  For example, the arguments

		 DATA{MyData/MyInput.mhd,MyInput.img}			# File pair
		 DATA{MyData/MyFrames00.png,REGEX:MyFrames[0-9]+\\.png} # Series

	      will pass MyInput.mha and MyFrames00.png on the command line but
	      ensure that the associated files are present next to them.

	      The  DATA{}  syntax  may	reference a directory using a trailing
	      slash   and   a	list   of   associated	 files.	   The	  form
	      DATA{<name>/,<opt1>,<opt2>,...} adds rules to fetch any files in
	      the directory that match one of  the  associated	file  options.
	      For  example,  the  argument DATA{MyDataDir/,REGEX:.*} will pass
	      the full path to a MyDataDir directory on the command  line  and
	      ensure  that the directory contains files corresponding to every
	      file or content link in the MyDataDir source directory.

	      The variable ExternalData_LINK_CONTENT may be set to the name of
	      a	 supported  hash  algorithm  to enable automatic conversion of
	      real data files referenced by the	 DATA{}	 syntax	 into  content
	      links.   For each such <file> a content link named "<file><ext>"
	      is created.  The original file is renamed to the	form  ".Exter‐
	      nalData_<algo>_<hash>"  to  stage	 it for future transmission to
	      one of the locations in the list of URL templates (by means out‐
	      side the scope of this module).  The data fetch rule created for
	      the content link will use the staged  object  if	it  cannot  be
	      found using any URL template.

	      The  variable ExternalData_OBJECT_STORES may be set to a list of
	      local  directories  that	store	objects	  using	  the	layout
	      <dir>/%(algo)/%(hash).  These directories will be searched first
	      for a needed object.  If the object  is  not  available  in  any
	      store  then  it will be fetched remotely using the URL templates
	      and added to the first local store listed.   If  no  stores  are
	      specified the default is a location inside the build tree.

	      The  variable ExternalData_SOURCE_ROOT may be set to the highest
	      source directory containing any path named by  a	DATA{}	refer‐
	      ence.	The    default	  is	CMAKE_SOURCE_DIR.    External‐
	      Data_SOURCE_ROOT and CMAKE_SOURCE_DIR must refer to  directories
	      within  a single source distribution (e.g. they come together in
	      one tarball).

	      The variable ExternalData_BINARY_ROOT may be set to  the	direc‐
	      tory to hold the real data files named by expanded DATA{} refer‐
	      ences.  The default is CMAKE_BINARY_DIR.	The  directory	layout
	      will    mirror   that   of   content   links   under   External‐
	      Data_SOURCE_ROOT.

	      Variables ExternalData_TIMEOUT_INACTIVITY and ExternalData_TIME‐
	      OUT_ABSOLUTE  set the download inactivity and absolute timeouts,
	      in seconds.  The	defaults  are  60  seconds  and	 300  seconds,
	      respectively.   Set  either  timeout  to	0  seconds  to disable
	      enforcement.

       ExternalProject
	      Create custom targets to build projects in external trees

	      The 'ExternalProject_Add' function creates a  custom  target  to
	      drive download, update/patch, configure, build, install and test
	      steps of an external project:

		ExternalProject_Add(<name>    # Name for custom target
		  [DEPENDS projects...]	      # Targets on which the project depends
		  [PREFIX dir]		      # Root dir for entire project
		  [LIST_SEPARATOR sep]	      # Sep to be replaced by ; in cmd lines

		 #--Custom targets-------------
		  [STEP_TARGETS st1 st2 ...]  # Generate custom targets for these steps
		  )

	      The *_DIR options specify	 directories  for  the	project,  with
	      default directories computed as follows. If the PREFIX option is
	      given to ExternalProject_Add() or the EP_PREFIX directory	 prop‐
	      erty  is	set,  then  an external project is built and installed
	      under the specified prefix:

		 TMP_DIR      = <prefix>/tmp
		 STAMP_DIR    = <prefix>/src/<name>-stamp
		 DOWNLOAD_DIR = <prefix>/src
		 SOURCE_DIR   = <prefix>/src/<name>
		 BINARY_DIR   = <prefix>/src/<name>-build
		 INSTALL_DIR  = <prefix>

	      Otherwise, if the EP_BASE directory property is set then	compo‐
	      nents  of	 an  external  project	are stored under the specified
	      base:

		 TMP_DIR      = <base>/tmp/<name>
		 STAMP_DIR    = <base>/Stamp/<name>
		 DOWNLOAD_DIR = <base>/Download/<name>
		 SOURCE_DIR   = <base>/Source/<name>
		 BINARY_DIR   = <base>/Build/<name>
		 INSTALL_DIR  = <base>/Install/<name>

	      If no PREFIX,  EP_PREFIX,	 or  EP_BASE  is  specified  then  the
	      default  is to set PREFIX to "<name>-prefix". Relative paths are
	      interpreted with respect to the build directory corresponding to
	      the source directory in which ExternalProject_Add is invoked.

	      If  SOURCE_DIR  is  explicitly  set to an existing directory the
	      project will be built from it. Otherwise a download step must be
	      specified	 using	one  of the DOWNLOAD_COMMAND, CVS_*, SVN_*, or
	      URL options. The URL option may refer locally to a directory  or
	      source   tarball,	  or   refer   to   a	remote	tarball	 (e.g.
	      http://.../src.tgz).

	      The 'ExternalProject_Add_Step' function adds a custom step to an
	      external project:

		ExternalProject_Add_Step(<name> <step> # Names of project and custom step
		  [COMMAND cmd...]	  # Command line invoked by this step
		  [COMMENT "text..."]	  # Text printed when step executes
		  [DEPENDEES steps...]	  # Steps on which this step depends
		  [DEPENDERS steps...]	  # Steps that depend on this step
		  [DEPENDS files...]	  # Files on which this step depends
		  [ALWAYS 1]		  # No stamp file, step always runs
		  [WORKING_DIRECTORY dir] # Working directory for command
		  [LOG 1]		  # Wrap step in script to log output
		  )

	      The  command line, comment, and working directory of every stan‐
	      dard  and	 custom	 step	is   processed	 to   replace	tokens
	      <SOURCE_DIR>,  <BINARY_DIR>,  <INSTALL_DIR>,  and <TMP_DIR> with
	      corresponding property values.

	      Any builtin step that specifies  a  "<step>_COMMAND  cmd..."  or
	      custom  step that specifies a "COMMAND cmd..." may specify addi‐
	      tional command lines using the form "COMMAND cmd...".  At	 build
	      time  the	 commands will be executed in order and aborted if any
	      one fails.  For example:

		... BUILD_COMMAND make COMMAND echo done ...

	      specifies to run "make" and then "echo done"  during  the	 build
	      step. Whether the current working directory is preserved between
	      commands is not defined.	Behavior of shell operators like  "&&"
	      is not defined.

	      The  'ExternalProject_Get_Property'  function retrieves external
	      project target properties:

		ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])

	      It stores property values in variables of the same  name.	 Prop‐
	      erty  names  correspond to the keyword argument names of 'Exter‐
	      nalProject_Add'.

	      The 'ExternalProject_Add_StepTargets' function generates	custom
	      targets for the steps listed:

		ExternalProject_Add_StepTargets(<name> [step1 [step2 [...]]])

	      If  STEP_TARGETS	is set then ExternalProject_Add_StepTargets is
	      automatically called at the end of matching calls	 to  External‐
	      Project_Add_Step.	 Pass  STEP_TARGETS  explicitly	 to individual
	      ExternalProject_Add calls, or  implicitly	 to  all  ExternalPro‐
	      ject_Add	calls  by  setting the directory property EP_STEP_TAR‐
	      GETS.

	      If STEP_TARGETS is not set,  clients  may	 still	manually  call
	      ExternalProject_Add_StepTargets	after	calling	  ExternalPro‐
	      ject_Add or ExternalProject_Add_Step.

	      This functionality is provided to make  it  easy	to  drive  the
	      steps independently of each other by specifying targets on build
	      command  lines.  For  example,  you  may	be  submitting	to   a
	      sub-project based dashboard, where you want to drive the config‐
	      ure portion of the build, then submit to the dashboard, followed
	      by  the build portion, followed by tests. If you invoke a custom
	      target that depends on a step halfway through  the  step	depen‐
	      dency chain, then all the previous steps will also run to ensure
	      everything is up to date.

	      For example, to drive configure, build and test  steps  indepen‐
	      dently  for each ExternalProject_Add call in your project, write
	      the following line prior to  any	ExternalProject_Add  calls  in
	      your CMakeLists file:

		 set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)

       FeatureSummary
	      Macros for generating a summary of enabled/disabled features

	      This  module  provides  the  macros feature_summary(), set_pack‐
	      age_properties() and add_feature_info().	For  compatibility  it
	      also   still  provides  set_package_info(),  set_feature_info(),
	      print_enabled_features() and print_disabled_features().

	      These macros can be used to generate a summary  of  enabled  and

				   [DESCRIPTION "Found packages:"]
				   WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND
					| ENABLED_FEATURES | DISABLED_FEATURES]
				 )

	      The  FEATURE_SUMMARY()  macro  can  be used to print information
	      about enabled or disabled packages or features of a project.  By
	      default, only the names of the features/packages will be printed
	      and their required version when one was specified. Use SET_PACK‐
	      AGE_PROPERTIES()	to  add	 more  useful information, like e.g. a
	      download URL for the respective package or their purpose in  the
	      project.

	      The  WHAT	 option is the only mandatory option. Here you specify
	      what information will be printed:

		  ALL: print everything
		  ENABLED_FEATURES: the list of all features which are enabled
		  DISABLED_FEATURES: the list of all features which are disabled
		  PACKAGES_FOUND: the list of all packages which have been found
		  PACKAGES_NOT_FOUND: the list of all packages which have not been found
		  OPTIONAL_PACKAGES_FOUND: only those packages which have been found which have the type OPTIONAL
		  OPTIONAL_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type OPTIONAL
		  RECOMMENDED_PACKAGES_FOUND: only those packages which have been found which have the type RECOMMENDED
		  RECOMMENDED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RECOMMENDED
		  REQUIRED_PACKAGES_FOUND: only those packages which have been found which have the type REQUIRED
		  REQUIRED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type REQUIRED
		  RUNTIME_PACKAGES_FOUND: only those packages which have been found which have the type RUNTIME
		  RUNTIME_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RUNTIME

	      If a FILENAME is given, the information  is  printed  into  this
	      file.  If APPEND is used, it is appended to this file, otherwise
	      the file is overwritten if it already existed. If the VAR option
	      is  used,	 the information is "printed" into the specified vari‐
	      able. If FILENAME is not used, the information is printed to the
	      terminal. Using the DESCRIPTION option a description or headline
	      can be set which will be printed above the  actual  content.  If
	      INCLUDE_QUIET_PACKAGES   is  given,  packages  which  have  been
	      searched with find_package(... QUIET) will also  be  listed.  By
	      default  they are skipped. If FATAL_ON_MISSING_REQUIRED_PACKAGES
	      is given, CMake will abort if  a	package	 which	is  marked  as
	      REQUIRED has not been found.

	      Example 1, append everything to a file:

		 feature_summary(WHAT ALL
				 FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)

	      Example 2, print the enabled features into the variable enabled‐
	      FeaturesText, including QUIET packages:

		 feature_summary(WHAT ENABLED_FEATURES
				 INCLUDE_QUIET_PACKAGES
				 DESCRIPTION "Enabled Features:"
				 VAR enabledFeaturesText)
		 message(STATUS "${enabledFeaturesText}")

		  SET_PACKAGE_PROPERTIES(<name> PROPERTIES [ URL <url> ]
							   [ DESCRIPTION <description> ]
							   [ TYPE (RUNTIME|OPTIONAL|RECOMMENDED|REQUIRED) ]
							   [ PURPOSE <purpose> ]
					)

	      Use this macro to set up information about  the  named  package,
	      which  can  then be displayed via FEATURE_SUMMARY(). This can be
	      done either directly in the Find-module or in the project	 which
	      uses  the module after the find_package() call. The features for
	      which information can be set  are	 added	automatically  by  the
	      find_package() command.

	      URL:  this  should  be the homepage of the package, or something
	      similar. Ideally this is set already directly in	the  Find-mod‐
	      ule.

	      DESCRIPTION:  A  short description what that package is, at most
	      one sentence. Ideally  this  is  set  already  directly  in  the
	      Find-module.

	      TYPE:  What  type	 of  dependency	 has the using project on that
	      package. Default is OPTIONAL. In this case it is a package which
	      can  be  used by the project when available at buildtime, but it
	      also work without. RECOMMENDED is similar to OPTIONAL, i.e.  the
	      project  will build if the package is not present, but the func‐
	      tionality of the resulting binaries will be severly limited.  If
	      a	 REQUIRED  package  is not available at buildtime, the project
	      may not even build. This can be combined with the FATAL_ON_MISS‐
	      ING_REQUIRED_PACKAGES  argument  for  feature_summary(). Last, a
	      RUNTIME package is a package which is actually not used  at  all
	      during the build, but which is required for actually running the
	      resulting binaries. So if such a package is missing, the project
	      can  still  be built, but it may not work later on. If set_pack‐
	      age_properties() is called multiple times for the	 same  package
	      with different TYPEs, the TYPE is only changed to higher TYPEs (
	      RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED ), lower  TYPEs  are
	      ignored.	The TYPE property is project-specific, so it cannot be
	      set by the Find-module, but must be set in the project.

	      PURPOSE: This describes which features this package  enables  in
	      the  project,  i.e. it tells the user what functionality he gets
	      in the resulting binaries. If set_package_properties() is called
	      multiple	times  for  a  package,	 all  PURPOSE  properties  are
	      appended to a list of purposes of the package in the project. As
	      the  TYPE	 property,  also  the PURPOSE property is project-spe‐
	      cific, so it cannot be set by the Find-module, but must  be  set
	      in the project.

	      Example for setting the info for a package:

		 find_package(LibXml2)
		 set_package_properties(LibXml2 PROPERTIES DESCRIPTION "A XML processing library."
							   URL "http://xmlsoft.org/")

		 set_package_properties(LibXml2 PROPERTIES TYPE RECOMMENDED
							   PURPOSE "Enables HTML-import in MyWordProcessor")
		 ...
		 set_package_properties(LibXml2 PROPERTIES TYPE OPTIONAL
							   PURPOSE "Enables odt-export in MyWordProcessor")

		 find_package(DBUS)
		 set_package_properties(DBUS PROPERTIES TYPE RUNTIME
							   PURPOSE "Necessary to disable the screensaver during a presentation" )

		  ADD_FEATURE_INFO(<name> <enabled> <description>)

	      Use this macro to add information about a feature with the given
	      <name>. <enabled> contains whether this feature  is  enabled  or
	      not,  <description> is a text describing the feature. The infor‐
	      mation can be displayed using feature_summary() for ENABLED_FEA‐
	      TURES and DISABLED_FEATURES respectively.

	      Example for setting the info for a feature:

		 option(WITH_FOO "Help for foo" ON)
		 add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.")

	      The  following macros are provided for compatibility with previ‐
	      ous CMake versions:

		  SET_PACKAGE_INFO(<name> <description> [<url> [<purpose>] ] )

	      Use this macro to set up information about  the  named  package,
	      which  can  then be displayed via FEATURE_SUMMARY(). This can be
	      done either directly in the Find-module or in the project	 which
	      uses  the module after the find_package() call. The features for
	      which information can be set  are	 added	automatically  by  the
	      find_package() command.

		  PRINT_ENABLED_FEATURES()

	      Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES  DESCRIP‐
	      TION "Enabled features:")

		  PRINT_DISABLED_FEATURES()

	      Does  the	  same	 as   FEATURE_SUMMARY(WHAT   DISABLED_FEATURES
	      DESCRIPTION "Disabled features:")

		  SET_FEATURE_INFO(<name> <description> [<url>] )

	      Does the same as SET_PACKAGE_INFO(<name> <description> <url> )

       FindALSA
	      Find alsa

	      Find the alsa libraries (asound)

		This module defines the following variables:
		   ALSA_FOUND	    - True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found
		   ALSA_LIBRARIES   - Set when ALSA_LIBRARY is found
		   ALSA_INCLUDE_DIRS - Set when ALSA_INCLUDE_DIR is found

		   ALSA_INCLUDE_DIR - where to find asoundlib.h, etc.

       FindAVIFile
	      Locate AVIFILE library and include paths

	      AVIFILE  (http://avifile.sourceforge.net/)is  a set of libraries
	      for i386 machines to use various AVI codecs. Support is  limited
	      beyond  Linux.  Windows  provides	 native	 AVI  support,	and so
	      doesn't need this library. This module defines

		AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
		AVIFILE_LIBRARIES, the libraries to link against
		AVIFILE_DEFINITIONS, definitions to use when compiling
		AVIFILE_FOUND, If false, don't try to use AVIFILE

       FindArmadillo
	      Find Armadillo

	      Find the Armadillo C++ library

	      Using Armadillo:

		find_package(Armadillo REQUIRED)
		include_directories(${ARMADILLO_INCLUDE_DIRS})
		add_executable(foo foo.cc)
		target_link_libraries(foo ${ARMADILLO_LIBRARIES})

	      This module sets the following variables:

		ARMADILLO_VERSION_NAME - name of the version (ex: "Antipodean Antileech")

       FindBISON
	      Find bison executable and provides  macros  to  generate	custom
	      build rules

	      The module defines the following variables:

		BISON_EXECUTABLE - path to the bison program
		BISON_VERSION - version of bison
		BISON_FOUND - true if the program was found

	      The minimum required version of bison can be specified using the
	      standard CMake syntax, e.g. find_package(BISON 2.1.3)

	      If bison is found, the module defines the macros:

		BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>]
			    [COMPILE_FLAGS <string>])

	      which will create	 a custom rule to generate  a parser. <YaccIn‐
	      put>  is	the path to  a yacc file. <CodeOutput> is the name  of
	      the source file generated by bison.  A header file is  also   be
	      generated,  and  contains	 the   token  list.  If	 COMPILE_FLAGS
	      option is	 specified,  the  next	parameter  is	added  in  the
	      bison  command line.  if	VERBOSE option is specified, <file> is
	      created  and contains verbose descriptions of  the  grammar  and
	      parser. The macro defines a set of variables:

		BISON_${Name}_DEFINED - true is the macro ran successfully
		BISON_${Name}_INPUT - The input source file, an alias for <YaccInput>
		BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison
		BISON_${Name}_OUTPUT_HEADER - The header file generated by bison
		BISON_${Name}_OUTPUTS - The sources files generated by bison
		BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line

		====================================================================
		Example:

		 find_package(BISON)
		 BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
		 add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
		====================================================================

       FindBLAS
	      Find BLAS library

	      This  module  finds an installed fortran library that implements
	      the	BLAS	   linear-algebra	 interface	  (see
	      http://www.netlib.org/blas/). The list of libraries searched for
	      is taken from the autoconf macro file, acx_blas.m4  (distributed
	      at http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

	      This module sets the following variables:

		BLAS_FOUND - set to true if a library implementing the BLAS interface
		  is found
		BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
		  and -L).
		BLAS_LIBRARIES - uncached list of libraries (using full path name) to
		  link against to use BLAS
		BLAS95_LIBRARIES - uncached list of libraries (using full path name)
		  to link against to use BLAS95 interface
		BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
		  is found
		BLA_STATIC  if set on this determines what kind of linkage we do (static)
		BLA_VENDOR  if set checks only the specified vendor, if not set checks
		   all the possibilities
		BLA_F95	    if set on tries to find the f95 interfaces for BLAS/LAPACK

	      C/CXX should be enabled to use Intel mkl

       FindBZip2
	      Try to find BZip2

	      Once done this will define

		BZIP2_FOUND - system has BZip2
		BZIP2_INCLUDE_DIR - the BZip2 include directory
		BZIP2_LIBRARIES - Link these to use BZip2
		BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_
		BZIP2_VERSION_STRING - the version of BZip2 found (since CMake 2.8.8)

       FindBoost
	      Find Boost include dirs and libraries

	      Use this module by invoking find_package with the form:

		find_package(Boost
		  [version] [EXACT]	 # Minimum or EXACT version e.g. 1.36.0
		  [REQUIRED]		 # Fail with error if Boost is not found
		  [COMPONENTS <libs>...] # Boost libraries by their canonical name
		  )			 # e.g. "date_time" for "libboost_date_time"

	      This module finds headers and requested component libraries OR a
	      CMake package configuration file provided	 by  a	"Boost	CMake"
	      build.   For  the	 latter case skip to the "Boost CMake" section
	      below.  For the former case results are reported in variables:

		Boost_FOUND	       - True if headers and requested libraries were found
		Boost_INCLUDE_DIRS     - Boost include directories
		Boost_LIBRARY_DIRS     - Link directories for Boost libraries
		Boost_LIBRARIES	       - Boost component libraries to be linked
		Boost_<C>_FOUND	       - True if component <C> was found (<C> is upper-case)
		Boost_<C>_LIBRARY      - Libraries to link for component <C> (may include
					 target_link_libraries debug/optimized keywords)
		Boost_VERSION	       - BOOST_VERSION value from boost/version.hpp
		Boost_LIB_VERSION      - Version string appended to library filenames
		Boost_MAJOR_VERSION    - Boost major version number (X in X.y.z)
		Boost_MINOR_VERSION    - Boost minor version number (Y in x.Y.z)
		Boost_SUBMINOR_VERSION - Boost subminor version number (Z in x.y.Z)
		Boost_LIB_DIAGNOSTIC_DEFINITIONS (Windows)
				       - Pass to add_definitions() to have diagnostic
					 information about Boost's automatic linking
					 displayed during compilation

	      This module reads hints about search locations from variables:

		BOOST_ROOT	       - Preferred installation prefix
		 (or BOOSTROOT)
		BOOST_INCLUDEDIR       - Preferred include directory e.g. <prefix>/include
		BOOST_LIBRARYDIR       - Preferred library directory e.g. <prefix>/lib
		Boost_NO_SYSTEM_PATHS  - Set to ON to disable searching in locations not
					 specified by these hint variables. Default is OFF.
		Boost_ADDITIONAL_VERSIONS
				       - List of Boost versions not known to this module
					 (Boost install locations may contain the version)

	      and saves search results persistently in CMake cache entries:

		Boost_INCLUDE_DIR	  - Directory containing Boost headers
		Boost_LIBRARY_DIR	  - Directory containing Boost libraries
		Boost_<C>_LIBRARY_DEBUG	  - Component <C> library debug variant
		Boost_<C>_LIBRARY_RELEASE - Component <C> library release variant

	      Users may set these hints or results as cache entries.  Projects
	      should not read these entries directly but instead use the above
	      result variables. Note that some hint names start in  upper-case
	      "BOOST".	One may specify these as environment variables if they
	      are not specified as CMake variables or cache entries.

	      This module first searches for the Boost header files using  the
	      above  hint variables (excluding BOOST_LIBRARYDIR) and saves the
	      result in Boost_INCLUDE_DIR.  Then  it  searches	for  requested
	      component	  libraries   using   the   above   hints   (excluding
	      BOOST_INCLUDEDIR and Boost_ADDITIONAL_VERSIONS), "lib"  directo‐
	      ries  near Boost_INCLUDE_DIR, and the library name configuration
	      settings	 below.	   It	saves	the   library	directory   in
	      Boost_LIBRARY_DIR	   and	 individual   library	locations   in
	      Boost_<C>_LIBRARY_DEBUG and Boost_<C>_LIBRARY_RELEASE.  When one
	      changes  settings	 used  by  previous searches in the same build
	      tree (excluding environment variables) this module discards pre‐
	      vious search results affected by the changes and searches again.

	      Boost  libraries	come  in  many	variants encoded in their file
	      name.  Users or projects may tell this module which  variant  to
	      find by setting variables:

		Boost_USE_MULTITHREADED	 - Set to OFF to use the non-multithreaded
					   libraries ('mt' tag).  Default is ON.
		Boost_USE_STATIC_LIBS	 - Set to ON to force the use of the static
					   libraries.  Default is OFF.
		Boost_USE_STATIC_RUNTIME - Set to ON or OFF to specify whether to use
					   libraries linked statically to the C++ runtime
					   ('s' tag).  Default is platform dependent.
		Boost_USE_DEBUG_PYTHON	 - Set to ON to use libraries compiled with a
					   debug Python build ('y' tag). Default is OFF.
		Boost_USE_STLPORT	 - Set to ON to use libraries compiled with
					   STLPort ('p' tag).  Default is OFF.
		Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
					 - Set to ON to use libraries compiled with
					   STLPort deprecated "native iostreams"
					   ('n' tag).  Default is OFF.
		Boost_COMPILER		 - Set to the compiler-specific library suffix
					   (e.g. "-gcc43").  Default is auto-computed
					   for the C++ compiler in use.
		Boost_THREADAPI		 - Suffix for "thread" component library name,
					   such as "pthread" or "win32".  Names with
					   and without this suffix will both be tried.

	      Other variables one may set to control this module are:

		Boost_DEBUG		 - Set to ON to enable debug output from FindBoost.
					   Please enable this before filing any bug report.
		Boost_DETAILED_FAILURE_MSG
					 - Set to ON to add detailed information to the
					   failure message even when the REQUIRED option
					   is not given to the find_package call.
		Boost_REALPATH		 - Set to ON to resolve symlinks for discovered
					   libraries to assist with packaging.	For example,
					   the "system" component library may be resolved to
					   "/usr/lib/libboost_system.so.1.42.0" instead of
					   "/usr/lib/libboost_system.so".  This does not
					   affect linking and should not be enabled unless
					   the user needs this information.

	      On  Visual  Studio  and  Borland compilers Boost headers request
	      automatic linking to  corresponding  libraries.	This  requires
	      matching	libraries  to be linked explicitly or available in the
	      link   library   search	path.	 In    this    case    setting
	      Boost_USE_STATIC_LIBS  to	 OFF  may not achieve dynamic linking.
	      Boost automatic linking typically requests static libraries with
	      a few exceptions (such as Boost.Python).	Use

		add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})

	      to  ask  Boost  to  report  information  about automatic linking
	      requests.

	      Example to find Boost headers only:

		find_package(Boost 1.36.0)
		if(Boost_FOUND)
		  include_directories(${Boost_INCLUDE_DIRS})
		  add_executable(foo foo.cc)
		endif()

	      Example to find Boost headers and some libraries:

		set(Boost_USE_STATIC_LIBS	 ON)
		set(Boost_USE_MULTITHREADED	 ON)
		set(Boost_USE_STATIC_RUNTIME	OFF)
		find_package(Boost 1.36.0 COMPONENTS date_time filesystem system ...)
		if(Boost_FOUND)
		  include_directories(${Boost_INCLUDE_DIRS})
		  add_executable(foo foo.cc)
		  target_link_libraries(foo ${Boost_LIBRARIES})
		endif()

	      Boost							 CMake
	      ----------------------------------------------------------

	      If  Boost	 was built using the boost-cmake project it provides a
	      package configuration file for use  with	find_package's	Config
	      mode.   This  module  looks  for	the package configuration file
	      called BoostConfig.cmake or boost-config.cmake  and  stores  the
	      result  in  cache entry "Boost_DIR".  If found, the package con‐
	      figuration file is loaded and this module returns with  no  fur‐
	      ther  action.  See documentation of the Boost CMake package con‐
	      figuration for details on what it provides.

	      Set  Boost_NO_BOOST_CMAKE	 to  ON	 to  disable  the  search  for
	      boost-cmake.

       FindBullet
	      Try to find the Bullet physics engine

		This module defines the following variables

		BULLET_FOUND - Was bullet found
		BULLET_INCLUDE_DIRS - the Bullet include directories
		BULLET_LIBRARIES - Link to this, by default it includes
				   all bullet components (Dynamics,
				   Collision, LinearMath, & SoftBody)

		This module accepts the following variables

		BULLET_ROOT - Can be set to bullet install path or Windows build path

       FindCABLE
	      Find CABLE

	      This module finds if CABLE is installed and determines where the
	      include files and libraries are.	This code sets	the  following
	      variables:

		CABLE		  the path to the cable executable
		CABLE_TCL_LIBRARY the path to the Tcl wrapper library
		CABLE_INCLUDE_DIR the path to the include directory

	      To build Tcl wrappers, you should add shared library and link it
	      to    ${CABLE_TCL_LIBRARY}.      You     should	  also	   add
	      ${CABLE_INCLUDE_DIR} as an include directory.

       FindCUDA
	      Tools  for  building CUDA C files: libraries and build dependen‐
	      cies.

	      This script locates the NVIDIA CUDA C tools. It should  work  on
	      linux, windows, and mac and should be reasonably up to date with
	      CUDA C releases.

	      This script makes use of the standard find_package arguments  of
	      <VERSION>,  REQUIRED  and	 QUIET.	  CUDA_FOUND will report if an
	      acceptable version of CUDA was found.

	      The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR
	      if  the  prefix  cannot be determined by the location of nvcc in
	      the system path and REQUIRED is specified to find_package().  To
	      use  a  different installed version of the toolkit set the envi‐
	      ronment  variable	 CUDA_BIN_PATH	before	running	 cmake	 (e.g.
	      CUDA_BIN_PATH=/usr/local/cuda1.0	  instead   of	 the   default
	      /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring.
	      If you change the value of CUDA_TOOLKIT_ROOT_DIR, various compo‐
	      nents that depend on the path will be relocated.

	      It might be necessary to set CUDA_TOOLKIT_ROOT_DIR  manually  on
	      certain platforms, or to use a cuda runtime not installed in the
	      default location. In newer versions  of  the  toolkit  the  cuda
	      library  is  included with the graphics driver- be sure that the
	      driver version matches what is needed by the cuda	 runtime  ver‐
	      sion.

	      The following variables affect the behavior of the macros in the
	      script (in alphebetical order).  Note that any  of  these	 flags
	      can be changed multiple times in the same directory before call‐
	      ing   CUDA_ADD_EXECUTABLE,    CUDA_ADD_LIBRARY,	 CUDA_COMPILE,
	      CUDA_COMPILE_PTX or CUDA_WRAP_SRCS.

		CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
		-- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
		   Note that making this different from the host code when generating object
		   or C files from CUDA code just won't work, because size_t gets defined by
		   nvcc in the generated source.  If you compile to PTX and then load the
		   file yourself, you can mix bit sizes between device and host.

		CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
		-- Set to ON if you want the custom build rule to be attached to the source
		   file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
		   targets.

		   This allows the user to build the target from the CUDA file; however, bad
		   things can happen if the CUDA source file is added to multiple targets.
		   When performing parallel builds it is possible for the custom build
		   command to be run more than once and in parallel causing cryptic build
		   errors.  VS runs the rules for every source file in the target, and a
		   source can have only one rule no matter how many projects it is added to.
		   When the rule is run from multiple targets race conditions can occur on
		   the generated file.	Eventually everything will get built, but if the user
		   is unaware of this behavior, there may be confusion.	 It would be nice if
		   this script could detect the reuse of source files across multiple targets
		   and turn the option off for the user, but no good solution could be found.

		CUDA_BUILD_CUBIN (Default OFF)
		-- Set to ON to enable and extra compilation pass with the -cubin option in
		   Device mode. The output is parsed and register, shared memory usage is
		   printed during build.

		CUDA_BUILD_EMULATION (Default OFF for device mode)
		-- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
		   when CUDA_BUILD_EMULATION is TRUE.

		CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
		-- Set to the path you wish to have the generated files placed.	 If it is
		   blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
		   Intermediate files will always be placed in
		   CMAKE_CURRENT_BINARY_DIR/CMakeFiles.

		CUDA_HOST_COMPILATION_CPP (Default ON)
		-- Set to OFF for C compilation of host code.

		CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER, $(VCInstallDir)/bin for VS)
		-- Set the host compiler to be used by nvcc.  Ignored if -ccbin or
		   --compiler-bindir is already present in the CUDA_NVCC_FLAGS or
		   CUDA_NVCC_FLAGS_<CONFIG> variables.	For Visual Studio targets
		   $(VCInstallDir)/bin is a special value that expands out to the path when
		   the command is run from withing VS.

		CUDA_NVCC_FLAGS
		CUDA_NVCC_FLAGS_<CONFIG>
		-- Additional NVCC command line arguments.  NOTE: multiple arguments must be
		   semi-colon delimited (e.g. --compiler-options;-Wall)

		CUDA_PROPAGATE_HOST_FLAGS (Default ON)
		-- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
		   dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
		   host compiler through nvcc's -Xcompiler flag.  This helps make the
		   generated host code match the rest of the system better.  Sometimes
		   certain flags give nvcc problems, and this will help you turn the flag
		   propagation off.  This does not affect the flags supplied directly to nvcc
		   via CUDA_NVCC_FLAGS or through the OPTION flags specified through
		   CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.  Flags used for
		   shared library compilation are not affected by this flag.

		CUDA_SEPARABLE_COMPILATION (Default OFF)
		-- If set this will enable separable compilation for all CUDA runtime object
		   files.  If used outside of CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY
		   (e.g. calling CUDA_WRAP_SRCS directly),
		   CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME and
		   CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS should be called.

		CUDA_VERBOSE_BUILD (Default OFF)
		-- Set to ON to see all the commands used when building the CUDA file.	When
		   using a Makefile generator the value defaults to VERBOSE (run make
		   VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
		   always print the output.

	      The script creates the following macros (in alphebetical order):

		CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
		-- Adds the cufft library to the target (can be any target).  Handles whether
		   you are in emulation mode or not.

		CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
		-- Adds the cublas library to the target (can be any target).  Handles
		   whether you are in emulation mode or not.

		CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
				     [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
		-- Creates an executable "cuda_target" which is made up of the files
		   specified.  All of the non CUDA C files are compiled using the standard
		   build rules specified by CMAKE and the cuda files are compiled to object
		   files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
		   added automatically to include_directories().  Some standard CMake target
		   calls can be used on the target after calling this macro
		   (e.g. set_target_properties and target_link_libraries), but setting
		   properties that adjust compilation flags will not affect code compiled by
		   nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
		   CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.

		CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
				  [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
		-- Same as CUDA_ADD_EXECUTABLE except that a library is created.

		CUDA_BUILD_CLEAN_TARGET()
		-- Creates a convience target that deletes all the dependency files
		   generated.  You should make clean after running this target to ensure the
		   dependency files get regenerated.

		CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
			      [OPTIONS ...] )
		-- Returns a list of generated files from the input source files to be used
		   with ADD_LIBRARY or ADD_EXECUTABLE.

		CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
		-- Returns a list of PTX files generated from the input source files.

		CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME( output_file_var
								     cuda_target
								     object_files )
		-- Compute the name of the intermediate link file used for separable
		   compilation.	 This file name is typically passed into
		   CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS.  output_file_var is produced
		   based on cuda_target the list of objects files that need separable
		   compilation as specified by object_files.  If the object_files list is
		   empty, then output_file_var will be empty.  This function is called
		   automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE.	Note that
		   this is a function and not a macro.

		CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
		-- Sets the directories that should be passed to nvcc
		   (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
		   files.

		CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target
							 nvcc_flags object_files)

		-- Generates the link object required by separable compilation from the given
		   object files.  This is called automatically for CUDA_ADD_EXECUTABLE and
		   CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS
		   directly.  When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the
		   nvcc_flags passed in are the same as the flags passed in via the OPTIONS
		   argument.  The only nvcc flag added automatically is the bitness flag as
		   specified by CUDA_64_BIT_DEVICE_CODE.  Note that this is a function
		   instead of a macro.

		CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
				 [STATIC | SHARED | MODULE] [OPTIONS ...] )
		-- This is where all the magic happens.	 CUDA_ADD_EXECUTABLE,
		   CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
		   function under the hood.

		   Given the list of files (file0 file1 ... fileN) this macro generates
		   custom commands that generate either PTX or linkable objects (use "PTX" or
		   "OBJ" for the format argument to switch).  Files that don't end with .cu
		   or have the HEADER_FILE_ONLY property are ignored.

		   The arguments passed in after OPTIONS are extra command line options to
		   give to nvcc.  You can also specify per configuration options by
		   specifying the name of the configuration followed by the options.  General
		   options must preceed configuration specific options.	 Not all
		   configurations need to be specified, only the ones provided will be used.

		      OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
		      DEBUG -g
		      RELEASE --use_fast_math
		      RELWITHDEBINFO --use_fast_math;-g
		      MINSIZEREL --use_fast_math

		   For certain configurations (namely VS generating object files with
		   CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
		   be produced for the given cuda file.	 This is because when you add the
		   cuda file to Visual Studio it knows that this file produces an object file
		   and will link in the resulting object file automatically.

		   This script will also generate a separate cmake script that is used at
		   build time to invoke nvcc.  This is for several reasons.

		     1. nvcc can return negative numbers as return values which confuses
		     Visual Studio into thinking that the command succeeded.  The script now
		     checks the error codes and produces errors when there was a problem.

		     2. nvcc has been known to not delete incomplete results when it
		     encounters problems.  This confuses build systems into thinking the
		     target was generated when in fact an unusable file exists.	 The script
		     now deletes the output files if there was an error.

		     3. By putting all the options that affect the build into a file and then
		     make the build rule dependent on the file, the output files will be
		     regenerated when the options change.

		   This script also looks at optional arguments STATIC, SHARED, or MODULE to
		   determine when to target the object compilation for a shared library.
		   BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
		   CUDA_ADD_LIBRARY.  On some systems special flags are added for building
		   objects intended for shared libraries.  A preprocessor macro,
		   <target_name>_EXPORTS is defined when a shared library compilation is
		   detected.

		   Flags passed into add_definitions with -D or /D are passed along to nvcc.

	      The script defines the following variables:

		CUDA_VERSION_MAJOR    -- The major version of cuda as reported by nvcc.
		CUDA_VERSION_MINOR    -- The minor version.
		CUDA_VERSION
		CUDA_VERSION_STRING   -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR

		CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
		CUDA_SDK_ROOT_DIR     -- Path to the CUDA SDK.	Use this to find files in the
					 SDK.  This script will not directly support finding
					 specific libraries or headers, as that isn't
					 supported by NVIDIA.  If you want to change
					 libraries when the path changes see the
					 FindCUDA.cmake script for an example of how to clear
					 these variables.  There are also examples of how to
					 use the CUDA_SDK_ROOT_DIR to locate headers or
					 libraries, if you so choose (at your own risk).
		CUDA_INCLUDE_DIRS     -- Include directory for cuda headers.  Added automatically
					 for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.
		CUDA_LIBRARIES	      -- Cuda RT library.
		CUDA_CUFFT_LIBRARIES  -- Device or emulation library for the Cuda FFT
					 implementation (alternative to:
					 CUDA_ADD_CUFFT_TO_TARGET macro)
		CUDA_CUBLAS_LIBRARIES -- Device or emulation library for the Cuda BLAS
					 implementation (alterative to:
					 CUDA_ADD_CUBLAS_TO_TARGET macro).
		CUDA_cupti_LIBRARY    -- CUDA Profiling Tools Interface library.
					 Only available for CUDA version 4.0+.
		CUDA_curand_LIBRARY   -- CUDA Random Number Generation library.
					 Only available for CUDA version 3.2+.
		CUDA_cusparse_LIBRARY -- CUDA Sparse Matrix library.
					 Only available for CUDA version 3.2+.
		CUDA_npp_LIBRARY      -- NVIDIA Performance Primitives library.

       FindCxxTest
	      Find CxxTest

	      Find the CxxTest suite and declare a helper macro	 for  creating
	      unit  tests and integrating them with CTest. For more details on
	      CxxTest see http://cxxtest.tigris.org

	      INPUT Variables

		 CXXTEST_USE_PYTHON [deprecated since 1.3]
		     Only used in the case both Python & Perl
		     are detected on the system to control
		     which CxxTest code generator is used.
		     Valid only for CxxTest version 3.

		     NOTE: In older versions of this Find Module,
		     this variable controlled if the Python test
		     generator was used instead of the Perl one,
		     regardless of which scripting language the
		     user had installed.

		 CXXTEST_TESTGEN_ARGS (since CMake 2.8.3)
		     Specify a list of options to pass to the CxxTest code
		     generator.	 If not defined, --error-printer is
		     passed.

	      OUTPUT Variables

		 CXXTEST_FOUND
		     True if the CxxTest framework was found
		 CXXTEST_INCLUDE_DIRS
		     Where to find the CxxTest include directory
		 CXXTEST_PERL_TESTGEN_EXECUTABLE
		     The perl-based test generator
		 CXXTEST_PYTHON_TESTGEN_EXECUTABLE
		     The python-based test generator
		 CXXTEST_TESTGEN_EXECUTABLE (since CMake 2.8.3)
		     The test generator that is actually used (chosen using user preferences
		     and interpreters found in the system)
		 CXXTEST_TESTGEN_INTERPRETER (since CMake 2.8.3)
		     The full path to the Perl or Python executable on the system

	      MACROS for optional use by CMake users:

		  CXXTEST_ADD_TEST(<test_name> <gen_source_file> <input_files_to_testgen...>)
		     Creates a CxxTest runner and adds it to the CTest testing suite
		     Parameters:
			 test_name		 The name of the test
			 gen_source_file	 The generated source filename to be
						 generated by CxxTest
			 input_files_to_testgen	 The list of header files containing the
						 CxxTest::TestSuite's to be included in
						 this runner

		     #==============
		     Example Usage:

			 find_package(CxxTest)
			 if(CXXTEST_FOUND)
			     include_directories(${CXXTEST_INCLUDE_DIR})
			     enable_testing()

			     CXXTEST_ADD_TEST(unittest_foo foo_test.cc
					       ${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h)
			     target_link_libraries(unittest_foo foo) # as needed
			 endif()

			    This will (if CxxTest is found):
			    1. Invoke the testgen executable to autogenerate foo_test.cc in the
			       binary tree from "foo_test.h" in the current source directory.
			    2. Create an executable and test called unittest_foo.

		    #=============
		    Example foo_test.h:

			#include <cxxtest/TestSuite.h>

			class MyTestSuite : public CxxTest::TestSuite
			{
			public:
			   void testAddition( void )
			   {
			      TS_ASSERT( 1 + 1 > 1 );
			      TS_ASSERT_EQUALS( 1 + 1, 2 );
			   }
			};

       FindCygwin
	      this module looks for Cygwin

       FindDCMTK
	      find DCMTK libraries and applications

       FindDart
	      Find DART

	      This module  looks  for  the  dart  testing  software  and  sets
	      DART_ROOT to point to where it found it.

       FindDevIL

	      This  module  locates the developer's image library. http://ope‐
	      nil.sourceforge.net/

	      This module sets:

		 IL_LIBRARIES -	  the name of the IL library. These include the full path to
				  the core DevIL library. This one has to be linked into the
				  application.
		 ILU_LIBRARIES -  the name of the ILU library. Again, the full path. This
				  library is for filters and effects, not actual loading. It
				  doesn't have to be linked if the functionality it provides
				  is not used.
		 ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the
				  library interfaces with OpenGL. It is not strictly needed
				  in applications.
		 IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files.
		 IL_FOUND -	  this is set to TRUE if all the above variables were set.
				  This will be set to false if ILU or ILUT are not found,
				  even if they are not needed. In most systems, if one
				  library is found all the others are as well. That's the
				  way the DevIL developers release it.

       FindDoxygen
	      This module looks for Doxygen and the path to Graphviz's dot

	      Doxygen  is  a  documentation  generation	 tool.	  Please   see
	      http://www.doxygen.org

	      This module accepts the following optional variables:

		 DOXYGEN_SKIP_DOT	= If true this module will skip trying to find Dot
					  (an optional component often used by Doxygen)

	      This modules defines the following variables:

		 DOXYGEN_EXECUTABLE	= The path to the doxygen command.
		 DOXYGEN_FOUND		= Was Doxygen found or not?
		 DOXYGEN_VERSION	= The version reported by doxygen --version

		 DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
		 DOXYGEN_DOT_FOUND	= Was Dot found or not?
		 DOXYGEN_DOT_PATH	= The path to dot not including the executable

       FindEXPAT
	      Find expat

	      Find the native EXPAT headers and libraries.

		EXPAT_INCLUDE_DIRS - where to find expat.h, etc.
		EXPAT_LIBRARIES	   - List of libraries when using expat.
		EXPAT_FOUND	   - True if expat found.

       FindFLEX
	      Find  flex  executable  and  provides a macro to generate custom
	      build rules

	      The module defines the following variables:

		FLEX_FOUND - true is flex executable is found
		FLEX_EXECUTABLE - the path to the flex executable
		FLEX_VERSION - the version of flex
		FLEX_LIBRARIES - The flex libraries
		FLEX_INCLUDE_DIRS - The path to the flex headers

	      The minimum required version of flex can be specified using  the
	      standard syntax, e.g. find_package(FLEX 2.5.13)

	      If flex is found on the system, the module provides the macro:

		FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])

	      which  creates  a	 custom	 command  to generate the <FlexOutput>
	      file from the <FlexInput> file.	If   COMPILE_FLAGS  option  is
	      specified,  the  next  parameter	is  added to the flex  command
	      line. Name is an alias used to  get   details  of	  this	custom
	      command.	Indeed the  macro defines  the following variables:

		FLEX_${Name}_DEFINED - true is the macro ran successfully
		FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
		alias for FlexOutput
		FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}

	      Flex  scanners  oftenly  use  tokens  defined by Bison: the code
	      generated by Flex	 depends of the header	 generated  by	Bison.
	      This module also defines a macro:

		ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)

	      which   adds the	required dependency  between a	scanner and  a
	      parser where  <FlexTarget>  and <BisonTarget>  are   the	 first
	      parameters  of respectively FLEX_TARGET and BISON_TARGET macros.

		====================================================================
		Example:

		 find_package(BISON)
		 find_package(FLEX)

		 BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
		 FLEX_TARGET(MyScanner lexer.l	${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp)
		 ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

		 include_directories(${CMAKE_CURRENT_BINARY_DIR})
		 add_executable(Foo
		    Foo.cc
		    ${BISON_MyParser_OUTPUTS}
		    ${FLEX_MyScanner_OUTPUTS}
		 )
		====================================================================

       FindFLTK
	      Find the native FLTK includes and library

	      By default FindFLTK.cmake will search for all of the FLTK compo‐
	      nents and add them to the FLTK_LIBRARIES variable.

		 You can limit the components which get placed in FLTK_LIBRARIES by
		 defining one or more of the following three options:

		   FLTK_SKIP_OPENGL, set to true to disable searching for opengl and
				     the FLTK GL library
		   FLTK_SKIP_FORMS, set to true to disable searching for fltk_forms
		   FLTK_SKIP_IMAGES, set to true to disable searching for fltk_images

		   FLTK_SKIP_FLUID, set to true if the fluid binary need not be present
				    at build time

	      The following variables will be defined:

		   FLTK_FOUND, True if all components not skipped were found
		   FLTK_INCLUDE_DIR, where to find include files
		   FLTK_LIBRARIES, list of fltk libraries you should link against
		   FLTK_FLUID_EXECUTABLE, where to find the Fluid tool
		   FLTK_WRAP_UI, This enables the FLTK_WRAP_UI command

	      The following cache variables are assigned  but  should  not  be
	      used. See the FLTK_LIBRARIES variable instead.

		   FLTK_BASE_LIBRARY   = the full path to fltk.lib
		   FLTK_GL_LIBRARY     = the full path to fltk_gl.lib
		   FLTK_FORMS_LIBRARY  = the full path to fltk_forms.lib
		   FLTK_IMAGES_LIBRARY = the full path to fltk_images.lib

       FindFLTK2
	      Find the native FLTK2 includes and library

	      The following settings are defined

		FLTK2_FLUID_EXECUTABLE, where to find the Fluid tool
		FLTK2_WRAP_UI, This enables the FLTK2_WRAP_UI command
		FLTK2_INCLUDE_DIR, where to find include files
		FLTK2_LIBRARIES, list of fltk2 libraries
		FLTK2_FOUND, Don't use FLTK2 if false.

		  include_directories(${GTEST_INCLUDE_DIRS})

		  add_executable(foo foo.cc)
		  target_link_libraries(foo ${GTEST_BOTH_LIBRARIES})

		  add_test(AllTestsInFoo foo)

	      If you would like each Google test to show up in CTest as a test
	      you  may	use  the following macro. NOTE: It will slow down your
	      tests by running an executable for each test and	test  fixture.
	      You will also have to rerun CMake after adding or removing tests
	      or test fixtures.

	      GTEST_ADD_TESTS(executable extra_args ARGN)

		GETTEXT_MSGFMT_EXECUTABLE: the full path to the msgfmt tool.
		GETTEXT_FOUND: True if gettext has been found.
		GETTEXT_VERSION_STRING: the version of gettext found (since CMake 2.8.8)

	      Additionally  it	provides  the  following  macros: GETTEXT_CRE‐
	      ATE_TRANSLATIONS ( outputFile [ALL] file1 ... fileN )

		  This will create a target "translations" which will convert the
		  given input po files into the binary output mo file. If the
		  ALL option is used, the translations will also be created when
		  building the default target.

	      GETTEXT_PROCESS_POT( <potfile> [ALL] [INSTALL_DESTINATION <dest‐
	      dir>] LANGUAGES <lang1> <lang2> ... )

		   Process the given pot file to mo files.
		   If INSTALL_DESTINATION is given then automatically install rules will be created,
		   the language subdirectory will be taken into account (by default use share/locale/).
		   If ALL is specified, the pot file is processed when building the all traget.
		   It creates a custom target "potfile".

	      GETTEXT_PROCESS_PO_FILES(	  <lang>   [ALL]  [INSTALL_DESTINATION
	      <dir>] PO_FILES <po1> <po2> ... )

		   Process the given po files to mo files for the given language.
		   If INSTALL_DESTINATION is given then automatically install rules will be created,
		   the language subdirectory will be taken into account (by default use share/locale/).
		   If ALL is specified, the po files are processed when building the all traget.
		   It creates a custom target "pofiles".

		   message("git found: ${GIT_EXECUTABLE}")
		 endif()

       FindGnuTLS

		GNUPLOT_EXECUTABLE - the Gnuplot executable
		GNUPLOT_VERSION_STRING - the version of Gnuplot found (since CMake 2.8.8)

	      GNUPLOT_VERSION_STRING will  not	work  for  old	versions  like
	      3.7.1.

       FindHDF5
	      Find  HDF5,  a  library  for reading and writing self describing
	      array data.

	      This module invokes the HDF5 wrapper  compiler  that  should  be
	      installed	 alongside  HDF5.   Depending upon the HDF5 Configura‐
	      tion, the wrapper compiler is called either h5cc or  h5pcc.   If
	      this  succeeds,  the module will then call the compiler with the
	      -show argument to see what flags are used when compiling an HDF5
	      client application.

	      The  module  will optionally accept the COMPONENTS argument.  If
	      no COMPONENTS are specified, then the find module	 will  default
	      to  finding  only the HDF5 C library.  If one or more COMPONENTS
	      are specified, the module will  attempt  to  find	 the  language
	      bindings	for  the  specified components.	 The only valid compo‐
	      nents are C, CXX, Fortran, HL, and Fortran_HL.   If  the	COMPO‐
	      NENTS  argument  is  not	given, the module will attempt to find
	      only the C bindings.

	      On  UNIX	systems,  this	 module	  will	 read	the   variable
	      HDF5_USE_STATIC_LIBRARIES	 to determine whether or not to prefer
	      a static link to a dynamic link for HDF5 and all of it's	depen‐
	      dencies.	  To   use   this   feature,   make   sure   that  the
	      HDF5_USE_STATIC_LIBRARIES variable is set	 before	 the  call  to
	      find_package.

	      To  provide the module with a hint about where to find your HDF5
	      installation, you can set the  environment  variable  HDF5_ROOT.
	      The  Find	 module will then look in this path when searching for
	      HDF5 executables, paths, and libraries.

	      In addition to finding the includes and  libraries  required  to
	      compile  an  HDF5	 client application, this module also makes an
	      effort to find tools that come with the HDF5  distribution  that
	      may be useful for regression testing.

	      This module will define the following variables:

		HDF5_INCLUDE_DIRS - Location of the hdf5 includes
		HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
		HDF5_DEFINITIONS - Required compiler definitions for HDF5

       FindImageMagick
	      Find the ImageMagick binary suite.

	      This module will search for a set of ImageMagick tools specified
	      as  components  in  the  FIND_PACKAGE  call.  Typical components

	      might have additional components not listed here):

		animate
		compare
		composite
		conjure
		convert
		display
		identify
		import
		mogrify
		montage
		stream

	      If  no  component is specified in the FIND_PACKAGE call, then it

		  This will create and install a simple libtool file for the given target.

	      KDE3_ADD_EXECUTABLE(name file1 ... fileN )

		  Currently identical to add_executable(), may provide some advanced features in the future.

	      KDE3_ADD_KPART(name [WITH_PREFIX] file1 ... fileN )

		  Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
		  If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.

       FindMPI
	      Find a Message Passing Interface (MPI) implementation

	      The  Message  Passing Interface (MPI) is a library used to write
	      high-performance distributed-memory parallel  applications,  and
	      is  typically deployed on a cluster. MPI is a standard interface
	      (defined by the MPI forum) for which  many  implementations  are
	      available.  All  of  them have somewhat different include paths,
	      libraries to link against, etc., and this module tries to smooth
	      out those differences.

	      === Variables ===

	      This  module  will  set  the following variables per language in
	      your project, where <lang> is one of C, CXX, or Fortran:

		 MPI_<lang>_FOUND	    TRUE if FindMPI found MPI flags for <lang>
		 MPI_<lang>_COMPILER	    MPI Compiler wrapper for <lang>
		 MPI_<lang>_COMPILE_FLAGS   Compilation flags for MPI programs
		 MPI_<lang>_INCLUDE_PATH    Include path(s) for MPI header
		 MPI_<lang>_LINK_FLAGS	    Linking flags for MPI programs
		 MPI_<lang>_LIBRARIES	    All libraries to link MPI programs against

	      Additionally, FindMPI sets the following variables  for  running
	      MPI programs from the command line:

		 MPIEXEC		    Executable for running MPI programs
		 MPIEXEC_NUMPROC_FLAG	    Flag to pass to MPIEXEC before giving
					    it the number of processors to run on
		 MPIEXEC_PREFLAGS	    Flags to pass to MPIEXEC directly
					    before the executable to run.
		 MPIEXEC_POSTFLAGS	    Flags to pass to MPIEXEC after other flags

	      === Usage ===

	      To  use  this  module, simply call FindMPI from a CMakeLists.txt
	      file, or run find_package(MPI), then  run	 CMake.	  If  you  are
	      happy  with  the auto- detected configuration for your language,
	      then you're done.	 If not, you have two options:

		 1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) of your
		    choice and reconfigure.  FindMPI will attempt to determine all the
		    necessary variables using THAT compiler's compile and link flags.
		 2. If this fails, or if your MPI implementation does not come with
		    a compiler wrapper, then set both MPI_<lang>_LIBRARIES and
		    MPI_<lang>_INCLUDE_PATH.  You may also set any other variables
		    listed above, but these two are required.  This will circumvent
		    autodetection entirely.

	      When configuration is successful,	 MPI_<lang>_COMPILER  will  be
	      set  to  the  compiler  wrapper  for  <lang>,  if	 it was found.
	      MPI_<lang>_FOUND and other variables above will be  set  if  any
	      MPI implementation was found for <lang>, regardless of whether a
	      compiler was found.

	      When using MPIEXEC to execute MPI applications, you should typi‐
	      cally use all of the MPIEXEC flags as follows:

		 ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS
		   ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS

	      where  PROCS is the number of processors on which to execute the
	      program, EXECUTABLE is the MPI program, and ARGS are  the	 argu‐
	      ments to pass to the MPI program.

	      === Backward Compatibility ===

	      For backward compatibility with older versions of FindMPI, these
	      variables are set, but deprecated:

		 MPI_FOUND	     MPI_COMPILER	 MPI_LIBRARY
		 MPI_COMPILE_FLAGS   MPI_INCLUDE_PATH	 MPI_EXTRA_LIBRARY
		 MPI_LINK_FLAGS	     MPI_LIBRARIES

	      In new projects, please use the MPI_<lang>_XXX equivalents.

	      if false, do not try to link to OpenAL OPENAL_INCLUDE_DIR, where
	      to find the headers

	      $OPENALDIR is an environment variable that would	correspond  to
	      the ./configure --prefix=$OPENALDIR used in building OpenAL.

	      Created  by  Eric Wing. This was influenced by the FindSDL.cmake
	      module.

       FindOpenGL
	      Try to find OpenGL

	      Once done this will define

		OPENGL_glu_LIBRARY  - Path to GLU Library

	      On OSX default to using the framework version of	opengl	People
	      will  have  to change the cache values of OPENGL_glu_LIBRARY and
	      OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX

       FindOpenMP
	      Finds OpenMP support

	      This module can be used to detect OpenMP support in a  compiler.
	      If  the  compiler supports OpenMP, the flags required to compile
	      with OpenMP support are returned in variables for the  different
	      languages.  The  variables may be empty if the compiler does not
	      need a special flag to support OpenMP.

	      The following variables are set:

		 OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support
		 OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support
		 OPENMP_FOUND - true if openmp is detected

	      Supported	     compilers	     can       be	found	    at
	      http://openmp.org/wp/openmp-compilers/

       FindOpenSSL
	      Try to find the OpenSSL encryption library

	      Once done this will define

		OPENSSL_ROOT_DIR - Set this variable to the root installation of OpenSSL

	      Read-Only variables:

		OPENSSL_FOUND - system has the OpenSSL library
		OPENSSL_INCLUDE_DIR - the OpenSSL include directory
		OPENSSL_LIBRARIES - The libraries needed to use OpenSSL
		OPENSSL_VERSION - This is set to $major.$minor.$revision$path (eg. 0.9.8s)

       FindOpenSceneGraph
	      Find OpenSceneGraph

	      This  module  searches for the OpenSceneGraph core "osg" library
	      as well  as  OpenThreads,	 and  whatever	additional  COMPONENTS
	      (nodekits) that you specify.

		  See http://www.openscenegraph.org

	      NOTE:  To	 use  this  module effectively you must either require
	      CMake >= 2.6.3  with  cmake_minimum_required(VERSION  2.6.3)  or
	      download	  and	place	FindOpenThreads.cmake,	 Findosg_func‐
	      tions.cmake, Findosg.cmake, and Find<etc>.cmake files into  your
	      CMAKE_MODULE_PATH.

	      ==================================

	      This module accepts the following variables (note mixed case)

		  OpenSceneGraph_DEBUG - Enable debugging output

		  OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
						    automatically

	      The following environment variables are also respected for find‐
	      ing the OSG and it's various components.	CMAKE_PREFIX_PATH  can
	      also be used for this (see find_library() CMake documentation).

		  <MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)
		  OSG_DIR
		  OSGDIR
		  OSG_ROOT

	      [CMake  2.8.10]:	The  CMake variable OSG_DIR can now be used as
	      well to influence detection, instead of needing  to  specify  an
	      environment variable.

	      This module defines the following output variables:

		  OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

		  OPENSCENEGRAPH_VERSION - The version of the OSG which was found

		  OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers

		  OPENSCENEGRAPH_LIBRARIES - The OSG libraries

	      ================================== Example Usage:

		find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil)
		    # libOpenThreads & libosg automatically searched
		include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})

		add_executable(foo foo.cc)
		target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})

       FindOpenThreads

	      OpenThreads  is a C++ based threading library. Its largest user‐
	      base seems to OpenSceneGraph so you might notice I accept OSGDIR
	      as  an  environment  path.  I consider this part of the Findosg*
	      suite used to find OpenSceneGraph components. Each component  is
	      separate and you must opt in to each module.

	      Locate   OpenThreads  This  module  defines  OPENTHREADS_LIBRARY
	      OPENTHREADS_FOUND, if false, do not try to link  to  OpenThreads
	      OPENTHREADS_INCLUDE_DIR, where to find the headers

	      $OPENTHREADS_DIR	is  an	environment variable that would corre‐
	      spond  to	 the  ./configure  --prefix=$OPENTHREADS_DIR  used  in
	      building osg.

	      [CMake  2.8.10]:	The CMake variables OPENTHREADS_DIR or OSG_DIR
	      can now be used as well to influence detection, instead of need‐
	      ing to specify an environment variable.

	      Created by Eric Wing.

       FindPHP4
	      Find PHP4

	      This  module finds if PHP4 is installed and determines where the
	      include files and libraries are. It  also	 determines  what  the
	      name of the library is. This code sets the following variables:

		PHP4_INCLUDE_PATH	= path to where php.h can be found
		PHP4_EXECUTABLE		= full path to the php4 binary

       FindPNG
	      Find the native PNG includes and library

	      This  module  searches  libpng, the library for working with PNG
	      images.

	      It defines the following variables

		PNG_INCLUDE_DIRS, where to find png.h, etc.
		PNG_LIBRARIES, the libraries to link against to use PNG.
		PNG_DEFINITIONS - You should add_definitons(${PNG_DEFINITIONS}) before compiling code that includes png library files.
		PNG_FOUND, If false, do not try to use PNG.
		PNG_VERSION_STRING - the version of the PNG library found (since CMake 2.8.8)

	      Also defined, but not for general use are

		PNG_LIBRARY, where to find the PNG library.

	      For backward compatiblity the variable PNG_INCLUDE_DIR  is  also
	      set. It has the same value as PNG_INCLUDE_DIRS.

	      Since  PNG  depends on the ZLib compression library, none of the
	      above will be defined unless ZLib can be found.

       FindPackageHandleStandardArgs

	      FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ... )

	      This function is intended to be used  in	FindXXX.cmake  modules
	      files.  It handles the REQUIRED, QUIET and version-related argu‐
	      ments to find_package(). It also	sets  the  <packagename>_FOUND
	      variable.	 The  package  is  considered  found  if all variables
	      <var1>... listed contain valid results, e.g. valid filepaths.

	      There are two modes of this function. The first argument in both
	      modes  is	 the  name  of	the Find-module where it is called (in
	      original casing).

	      The first simple mode looks like this:

		  FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )

	      If the variables <var1> to <varN> are all	 valid,	 then  <UPPER‐
	      CASED_NAME>_FOUND	 will  be set to TRUE. If DEFAULT_MSG is given
	      as second argument, then the function will generate itself  use‐
	      ful  success  and	 error	messages. You can also supply a custom
	      error message for the failure case. This is not recommended.

	      The second mode is  more	powerful  and  also  supports  version
	      checking:

		  FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME [FOUND_VAR <resultVar>]
							 [REQUIRED_VARS <var1>...<varN>]
							 [VERSION_VAR	<versionvar>]
							 [HANDLE_COMPONENTS]
							 [CONFIG_MODE]
							 [FAIL_MESSAGE "Custom failure message"] )

	      In  this mode, the name of the result-variable can be set either
	      to either <UPPERCASED_NAME>_FOUND	 or  <OriginalCase_Name>_FOUND
	      using  the FOUND_VAR option. Other names for the result-variable
	      are not allowed. So for a	 Find-module  named  FindFooBar.cmake,
	      the  two possible names are FooBar_FOUND and FOOBAR_FOUND. It is
	      recommended to use the original case version. If	the  FOUND_VAR
	      option is not used, the default is <UPPERCASED_NAME>_FOUND.

	      As  in  the simple mode, if <var1> through <varN> are all valid,
	      <packagename>_FOUND will be set to TRUE. After REQUIRED_VARS the
	      variables	 which	are required for this package are listed. Fol‐
	      lowing VERSION_VAR the name of the  variable  can	 be  specified
	      which  holds the version of the package which has been found. If
	      this is done, this version will be checked against  the  (poten‐
	      tially)  specified  required  version used in the find_package()
	      call. The EXACT keyword is also handled.	The  default  messages
	      include  information  about the required version and the version
	      which has been actually found, both if the version is ok or not.
	      If  the  package	supports components, use the HANDLE_COMPONENTS
	      option to enable handling them. In this case,  find_package_han‐
	      dle_standard_args() will report which components have been found
	      and which are missing, and the <packagename>_FOUND variable will
	      be  set to FALSE if any of the required components (i.e. not the
	      ones listed after	 OPTIONAL_COMPONENTS)  are  missing.  Use  the
	      option CONFIG_MODE if your FindXXX.cmake module is a wrapper for
	      a find_package(... NO_MODULE) call.  In  this  case  VERSION_VAR
	      will  be	set to <NAME>_VERSION and the macro will automatically
	      check whether the Config module was found.  Via  FAIL_MESSAGE  a
	      custom  failure  message	can be specified, if this is not used,
	      the default message will be displayed.

	      Example for mode 1:

		  find_package_handle_standard_args(LibXml2  DEFAULT_MSG  LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)

	      LibXml2 is considered to be found, if both  LIBXML2_LIBRARY  and
	      LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to
	      TRUE. If it is not found and REQUIRED was used,  it  fails  with
	      FATAL_ERROR, independent whether QUIET was used or not. If it is
	      found, success  will  be	reported,  including  the  content  of
	      <var1>.  On  repeated  Cmake  runs,  the	same  message won't be
	      printed again.

	      Example for mode 2:

		  find_package_handle_standard_args(LibXslt FOUND_VAR LibXslt_FOUND
							   REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS
							   VERSION_VAR LibXslt_VERSION_STRING)

	      In this case, LibXslt is considered to be	 found	if  the	 vari‐
	      able(s)	listed	 after	 REQUIRED_VAR	are  all  valid,  i.e.
	      LibXslt_LIBRARIES and LibXslt_INCLUDE_DIRS  in  this  case.  The
	      result  will  then be stored in LibXslt_FOUND . Also the version
	      of LibXslt will be checked by using  the	version	 contained  in
	      LibXslt_VERSION_STRING.  Since  no  FAIL_MESSAGE	is  given, the
	      default messages will be printed.

	      Another example for mode 2:

		  find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
		  find_package_handle_standard_args(Automoc4  CONFIG_MODE)

	      In this case,  FindAutmoc4.cmake	wraps  a  call	to  find_pack‐
	      age(Automoc4  NO_MODULE) and adds an additional search directory
	      for automoc4. Here the result will be stored in  AUTOMOC4_FOUND.
	      The  following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces
	      a proper success/error message.

       FindPackageMessage

	      FIND_PACKAGE_MESSAGE(<name>  "message  for  user"	 "find	result
	      details")

	      This  macro  is  intended	 to  be	 used in FindXXX.cmake modules
	      files. It will print a message once for each unique find result.
	      This  is	useful for telling the user where a package was found.
	      The first argument specifies the name (XXX) of the package.  The
	      second  argument	specifies  the	message	 to display. The third
	      argument lists details about the find result  so	that  if  they
	      change the message will be displayed again. The macro also obeys
	      the QUIET argument to the find_package command.

	      Example:

		if(X11_FOUND)
		  FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
		    "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
		else()
		 ...
		endif()

       FindPerl
	      Find perl

	      this module looks for Perl

		PERL_EXECUTABLE	    - the full path to perl
		PERL_FOUND	    - If false, don't attempt to use perl.
		PERL_VERSION_STRING - version of perl found (since CMake 2.8.8)

       FindPerlLibs
	      Find Perl libraries

	      This module finds if PERL is installed and determines where  the
	      include  files  and  libraries  are. It also determines what the
	      name of the library is. This code sets the following variables:

		PERLLIBS_FOUND	  = True if perl.h & libperl were found
		PERL_INCLUDE_PATH = path to where perl.h is found
		PERL_LIBRARY	  = path to libperl

		The following variables are also available if needed
		(introduced after CMake 2.6.4)

		PERL_SITESEARCH	   = path to the sitesearch install dir
		PERL_SITELIB	   = path to the sitelib install directory
		PERL_VENDORARCH	   = path to the vendor arch install directory
		PERL_VENDORLIB	   = path to the vendor lib install directory

       FindPhysFS

	      Locate  PhysFS  library  This module defines PHYSFS_LIBRARY, the
	      name of the library to link against PHYSFS_FOUND, if  false,  do
	      not  try	to  link  to  PHYSFS PHYSFS_INCLUDE_DIR, where to find
	      physfs.h

	      $PHYSFSDIR is an environment variable that would	correspond  to
	      the ./configure --prefix=$PHYSFSDIR used in building PHYSFS.

       FindPike
	      Find Pike

	      This  module finds if PIKE is installed and determines where the
	      include files and libraries are. It  also	 determines  what  the
	      name of the library is. This code sets the following variables:

		PIKE_INCLUDE_PATH	= path to where program.h is found
		PIKE_EXECUTABLE		= full path to the pike binary

       FindPkgConfig
	      a pkg-config module for CMake

	      Usage:

		 pkg_check_modules(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
		   checks for all the given modules

		 pkg_search_module(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
		   checks for given modules and uses the first working one

	      When  the	 'REQUIRED' argument was set, macros will fail with an
	      error when module(s) could not be found

	      When the 'QUIET' argument is set, no  status  messages  will  be
	      printed.

	      It sets the following variables:

		 PKG_CONFIG_FOUND	   ... if pkg-config executable was found
		 PKG_CONFIG_EXECUTABLE	   ... pathname of the pkg-config program
		 PKG_CONFIG_VERSION_STRING ... the version of the pkg-config program found
					       (since CMake 2.8.8)

	      For  the following variables two sets of values exist; first one
	      is the common one and has the given PREFIX. The second set  con‐
	      tains  flags  which are given out when pkgconfig was called with
	      the '--static' option.

		 <XPREFIX>_FOUND	  ... set to 1 if module(s) exist
		 <XPREFIX>_LIBRARIES	  ... only the libraries (w/o the '-l')
		 <XPREFIX>_LIBRARY_DIRS	  ... the paths of the libraries (w/o the '-L')
		 <XPREFIX>_LDFLAGS	  ... all required linker flags
		 <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
		 <XPREFIX>_INCLUDE_DIRS	  ... the '-I' preprocessor flags (w/o the '-I')
		 <XPREFIX>_CFLAGS	  ... all required cflags
		 <XPREFIX>_CFLAGS_OTHER	  ... the other compiler flags

		 <XPREFIX> = <PREFIX>	     for common case
		 <XPREFIX> = <PREFIX>_STATIC for static linking

	      There are some special variables whose  prefix  depends  on  the
	      count  of given modules. When there is only one module, <PREFIX>
	      stays unchanged. When there are  multiple	 modules,  the	prefix
	      will be changed to <PREFIX>_<MODNAME>:

		 <XPREFIX>_VERSION    ... version of the module
		 <XPREFIX>_PREFIX     ... prefix-directory of the module
		 <XPREFIX>_INCLUDEDIR ... include-dir of the module
		 <XPREFIX>_LIBDIR     ... lib-dir of the module

		 <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
		 <XPREFIX> = <PREFIX>_<MODNAME>

	      A <MODULE> parameter can have the following formats:

		 {MODNAME}	      ... matches any version
		 {MODNAME}>={VERSION} ... at least version <VERSION> is required
		 {MODNAME}={VERSION}  ... exactly version <VERSION> is required
		 {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

	      Examples

		 pkg_check_modules (GLIB2   glib-2.0)

		 pkg_check_modules (GLIB2   glib-2.0>=2.10)
		   requires at least version 2.10 of glib2 and defines e.g.
		     GLIB2_VERSION=2.10.3

		 pkg_check_modules (FOO	    glib-2.0>=2.10 gtk+-2.0)
		   requires both glib2 and gtk2, and defines e.g.
		     FOO_glib-2.0_VERSION=2.10.3
		     FOO_gtk+-2.0_VERSION=2.8.20

		 pkg_check_modules (XRENDER REQUIRED xrender)
		   defines e.g.:
		     XRENDER_LIBRARIES=Xrender;X11
		     XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

		 pkg_search_module (BAR	    libxml-2.0 libxml2 libxml>=2)

       FindPostgreSQL
	      Find the PostgreSQL installation.

	      In Windows, we make the assumption that, if the PostgreSQL files
	      are  installed,  the  default  directory	will   be   C:\Program
	      Files\PostgreSQL.

	      This module defines

		PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking
		PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers
		PostgreSQL_VERSION_STRING - the version of PostgreSQL found (since CMake 2.8.8)

       FindProducer

	      Though  Producer isn't directly part of OpenSceneGraph, its pri‐
	      mary user is OSG so I consider this part of the  Findosg*	 suite
	      used  to	find  OpenSceneGraph  components. You'll notice that I
	      accept OSGDIR as an environment path.

	      Each component is separate and you must opt in to	 each  module.
	      You  must	 also opt into OpenGL (and OpenThreads?) as these mod‐
	      ules won't do it for you. This is to allow you control over your
	      own system piece by piece in case you need to opt out of certain
	      components or change the Find behavior for a  particular	module
	      (perhaps	because	 the  default  FindOpenGL.cmake module doesn't
	      work with your system as an example). If you want to use a  more
	      convenient  module  that	includes everything, use the FindOpen‐
	      SceneGraph.cmake instead of the Findosg*.cmake modules.

	      Locate  Producer	This  module  defines  PRODUCER_LIBRARY	  PRO‐
	      DUCER_FOUND,  if	false,	do  not	 try  to link to Producer PRO‐
	      DUCER_INCLUDE_DIR, where to find the headers

	      $PRODUCER_DIR is an environment variable that  would  correspond
	      to the ./configure --prefix=$PRODUCER_DIR used in building osg.

       FindProtobuf

	      Locate and configure the Google Protocol Buffers library.

	      The following variables can be set and are optional:

		 PROTOBUF_SRC_ROOT_FOLDER - When compiling with MSVC, if this cache variable is set
					    the protobuf-default VS project build locations
					    (vsprojects/Debug & vsprojects/Release) will be searched
					    for libraries and binaries.

		 PROTOBUF_IMPORT_DIRS	  - List of additional directories to be searched for
					    imported .proto files. (New in CMake 2.8.8)

	      Defines the following variables:

		 PROTOBUF_FOUND - Found the Google Protocol Buffers library (libprotobuf & header files)

       FindPythonInterp
	      Find python interpreter

	      This module finds if Python interpreter is installed and	deter‐
	      mines  where  the	 executables are. This code sets the following
	      variables:

		PYTHONINTERP_FOUND	   - Was the Python executable found
		PYTHON_EXECUTABLE	   - path to the Python interpreter

		PYTHON_VERSION_STRING	   - Python version found e.g. 2.5.2
		PYTHON_VERSION_MAJOR	   - Python major version found e.g. 2
		PYTHON_VERSION_MINOR	   - Python minor version found e.g. 5
		PYTHON_VERSION_PATCH	   - Python patch version found e.g. 2

	      The Python_ADDITIONAL_VERSIONS variable can be used to specify a
	      list  of	version numbers that should be taken into account when
	      searching for Python. You need to set this variable before call‐
	      ing find_package(PythonInterp).

       FindPythonLibs
	      Find python libraries

	      This  module  finds  if Python is installed and determines where
	      the include files and libraries are. It also determines what the
	      name of the library is. This code sets the following variables:

		PYTHONLIBS_FOUND	   - have the Python libs been found
		PYTHON_LIBRARIES	   - path to the python library
		PYTHON_INCLUDE_PATH	   - path to where Python.h is found (deprecated)
		PYTHON_INCLUDE_DIRS	   - path to where Python.h is found
		PYTHON_DEBUG_LIBRARIES	   - path to the debug library (deprecated)
		PYTHONLIBS_VERSION_STRING  - version of the Python libs found (since CMake 2.8.8)

	      The Python_ADDITIONAL_VERSIONS variable can be used to specify a
	      list of version numbers that should be taken into	 account  when
	      searching for Python. You need to set this variable before call‐
	      ing find_package(PythonLibs).

	      If you'd like to specify the installation of Python to use,  you
	      should modify the following cache variables:

		PYTHON_LIBRARY		   - path to the python library
		PYTHON_INCLUDE_DIR	   - path to where Python.h is found

       FindQt Searches for all installed versions of Qt.

	      This  should only be used if your project can work with multiple
	      versions of Qt.  If not, you should just directly use FindQt4 or
	      FindQt3.	If  multiple  versions of Qt are found on the machine,
	      then The user must set the option DESIRED_QT_VERSION to the ver‐
	      sion  they  want	to use.	 If only one version of qt is found on
	      the machine, then the DESIRED_QT_VERSION is set to that  version
	      and the matching FindQt3 or FindQt4 module is included. Once the
	      user sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4 module
	      is included.

		QT_REQUIRED if this is set to TRUE then if CMake can
			    not find Qt4 or Qt3 an error is raised
			    and a message is sent to the user.

		DESIRED_QT_VERSION OPTION is created
		QT4_INSTALLED is set to TRUE if qt4 is found.
		QT3_INSTALLED is set to TRUE if qt3 is found.

       FindQt3
	      Locate Qt include paths and libraries

	      This module defines:

		QT_INCLUDE_DIR	  - where to find qt.h, etc.
		QT_LIBRARIES	  - the libraries to link against to use Qt.
		QT_DEFINITIONS	  - definitions to use when
				    compiling code that uses Qt.
		QT_FOUND	  - If false, don't try to use Qt.
		QT_VERSION_STRING - the version of Qt found

	      If  you need the multithreaded version of Qt, set QT_MT_REQUIRED
	      to TRUE

	      Also defined, but not for general use are:

		QT_MOC_EXECUTABLE, where to find the moc tool.
		QT_UIC_EXECUTABLE, where to find the uic tool.
		QT_QT_LIBRARY, where to find the Qt library.
		QT_QTMAIN_LIBRARY, where to find the qtmain
		 library. This is only required by Qt3 on Windows.

       FindQt4
	      Find Qt 4

	      This module can be used to find Qt4. The most important issue is
	      that  the Qt4 qmake is available via the system path. This qmake
	      is then used to detect basically everything  else.  This	module
	      defines  a  number  of  key  variables  and macros. The variable
	      QT_USE_FILE is set which is the path to a CMake file that can be
	      included to compile Qt 4 applications and libraries.  It sets up
	      the compilation environment for include directories,  preproces‐
	      sor defines and populates a QT_LIBRARIES variable.

	      Typical usage could be something like:

		 find_package(Qt4 4.4.3 REQUIRED QtCore QtGui QtXml)
		 include(${QT_USE_FILE})
		 add_executable(myexe main.cpp)
		 target_link_libraries(myexe ${QT_LIBRARIES})

	      The minimum required version can be specified using the standard
	      find_package()-syntax (see  example  above).  For	 compatibility
	      with  older versions of FindQt4.cmake it is also possible to set
	      the variable QT_MIN_VERSION to the minimum required  version  of
	      Qt4  before the find_package(Qt4) command. If both are used, the
	      version used in the find_package()  command  overrides  the  one
	      from QT_MIN_VERSION.

	      When  using  the	components  argument, QT_USE_QT* variables are
	      automatically set for the QT_USE_FILE to pick up.	 If one wishes
	      to manually set them, the available ones to set include:

				  QT_DONT_USE_QTCORE
				  QT_DONT_USE_QTGUI
				  QT_USE_QT3SUPPORT
				  QT_USE_QTASSISTANT
				  QT_USE_QAXCONTAINER
				  QT_USE_QAXSERVER
				  QT_USE_QTDESIGNER
				  QT_USE_QTMOTIF
				  QT_USE_QTMAIN
				  QT_USE_QTMULTIMEDIA
				  QT_USE_QTNETWORK
				  QT_USE_QTNSPLUGIN
				  QT_USE_QTOPENGL
				  QT_USE_QTSQL
				  QT_USE_QTXML
				  QT_USE_QTSVG
				  QT_USE_QTTEST
				  QT_USE_QTUITOOLS
				  QT_USE_QTDBUS
				  QT_USE_QTSCRIPT
				  QT_USE_QTASSISTANTCLIENT
				  QT_USE_QTHELP
				  QT_USE_QTWEBKIT
				  QT_USE_QTXMLPATTERNS
				  QT_USE_PHONON
				  QT_USE_QTSCRIPTTOOLS
				  QT_USE_QTDECLARATIVE

		QT_USE_IMPORTED_TARGETS
		      If this variable is set to TRUE, FindQt4.cmake will create imported
		      library targets for the various Qt libraries and set the
		      library variables like QT_QTCORE_LIBRARY to point at these imported
		      targets instead of the library file on disk. This provides much better
		      handling of the release and debug versions of the Qt libraries and is
		     also always backwards compatible, except for the case that dependencies
		     of libraries are exported, these will then also list the names of the
		     imported targets as dependency and not the file location on disk. This
		     is much more flexible, but requires that FindQt4.cmake is executed before
		     such an exported dependency file is processed.

		     Note that if using IMPORTED targets, the qtmain.lib static library is
		     automatically linked on Windows. To disable that globally, set the
		     QT4_NO_LINK_QTMAIN variable before finding Qt4. To disable that for a
		     particular executable, set the QT4_NO_LINK_QTMAIN target property to
		     True on the executable.

		QT_INCLUDE_DIRS_NO_SYSTEM
		      If this variable is set to TRUE, the Qt include directories
		      in the QT_USE_FILE will NOT have the SYSTEM keyword set.

	      There  are also some files that need processing by some Qt tools
	      such as moc and uic.  Listed below are macros that may  be  used
	      to process those files.

		macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
		      create moc code from a list of files containing Qt class with
		      the Q_OBJECT declaration.	 Per-directory preprocessor definitions
		      are also added.  Options may be given to moc, such as those found
		      when executing "moc -help".

		macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
		      create code from a list of Qt designer ui files.
		      Options may be given to uic, such as those found
		      when executing "uic -help"

		macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
		      create code from a list of Qt resource files.
		      Options may be given to rcc, such as those found
		      when executing "rcc -help"

		macro QT4_GENERATE_MOC(inputfile outputfile )
		      creates a rule to run moc on infile and create outfile.
		      Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
		      because you need a custom filename for the moc file or something similar.

		macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
		      The qt4_automoc macro is obsolete.  Use the CMAKE_AUTOMOC feature instead.
		      This macro is still experimental.
		      It can be used to have moc automatically handled.
		      So if you have the files foo.h and foo.cpp, and in foo.h a
		      a class uses the Q_OBJECT macro, moc has to run on it. If you don't
		      want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
		      #include "foo.moc"
		      in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
		      scan all listed files at cmake-time for such included moc files and if it finds
		      them cause a rule to be generated to run moc at build time on the
		      accompanying header file foo.h.
		      If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

		      You should have a look on the AUTOMOC property for targets to achieve the same results.

		macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
		      Create the interface header and implementation files with the
		      given basename from the given interface xml file and add it to
		      the list of sources.

		      You can pass additional parameters to the qdbusxml2cpp call by setting
		      properties on the input file:

		      INCLUDE the given file will be included in the generate interface header

		      CLASSNAME the generated class is named accordingly

		      NO_NAMESPACE the generated class is not wrapped in a namespace

		macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
		      Create the interface header and implementation files
		      for all listed interface xml files.
		      The basename will be automatically determined from the name of the xml file.

		      The source file properties described for QT4_ADD_DBUS_INTERFACE also apply here.

		macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname])
		      create a dbus adaptor (header and implementation file) from the xml file
		      describing the interface, and add it to the list of sources. The adaptor
		      forwards the calls to a parent class, defined in parentheader and named
		      parentclassname. The name of the generated files will be
		      <basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file.
		      If <classname> is provided, then it will be used as the classname of the
		      adaptor itself.

		macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
		      generate the xml interface file from the given header.
		      If the optional argument interfacename is omitted, the name of the
		      interface file is constructed from the basename of the header with
		      the suffix .xml appended.
		      Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"

		macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
					      ts_files ... OPTIONS ...)
		      out: qm_files
		      in:  directories sources ts_files
		      options: flags to pass to lupdate, such as -extensions to specify
		      extensions for a directory scan.
		      generates commands to create .ts (vie lupdate) and .qm
		      (via lrelease) - files from directories and/or sources. The ts files are
		      created and/or updated in the source tree (unless given with full paths).
		      The qm files are generated in the build tree.
		      Updating the translations can be done by adding the qm_files
		      to the source list of your library/executable, so they are
		      always updated, or by adding a custom target to control when
		      they get updated/generated.

		macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
		      out: qm_files
		      in:  ts_files
		      generates commands to create .qm from .ts - files. The generated
		      filenames can be found in qm_files. The ts_files
		      must exist and are not updated in any way.

	      function QT4_USE_MODULES( target [link_type] modules...)

		      This function is obsolete. Use target_link_libraries with IMPORTED targets instead.
		      Make <target> use the <modules> from Qt. Using a Qt module means
		      to link to the library, add the relevant include directories for the module,
		      and add the relevant compiler defines for using the module.
		      Modules are roughly equivalent to components of Qt4, so usage would be
		      something like:
		       qt4_use_modules(myexe Core Gui Declarative)
		      to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument can
		      be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the same argument
		      to the target_link_libraries call.

		Below is a detailed list of variables that FindQt4.cmake sets.
		QT_FOUND	 If false, don't try to use Qt.
		Qt4_FOUND	 If false, don't try to use Qt 4.
		QT4_FOUND	 If false, don't try to use Qt 4. This variable is for compatibility only.

       FindQuickTime

	      Locate QuickTime This module  defines  QUICKTIME_LIBRARY	QUICK‐
	      TIME_FOUND,  if  false,  do  not	try  to	 link  to  gdal QUICK‐
	      TIME_INCLUDE_DIR, where to find the headers

	      $QUICKTIME_DIR is an environment variable that would  correspond
	      to the ./configure --prefix=$QUICKTIME_DIR

	      Created by Eric Wing.

       FindRTI
	      Try to find M&S HLA RTI libraries

	      This  module  finds  if any HLA RTI is installed and locates the
	      standard RTI include files and libraries.

	      RTI is a simulation  infrastructure  standardized	 by  IEEE  and
	      SISO. It has a well defined C++ API that assures that simulation
	      applications are independent on a particular RTI implementation.

		http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)

	      This code sets the following variables:

		RTI_INCLUDE_DIR = the directory where RTI includes file are found
		RTI_LIBRARIES = The libraries to link against to use RTI
		RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
		RTI_FOUND = Set to FALSE if any HLA RTI was not found

	      Report problems to <certi-devel@nongnu.org>

       FindRuby
	      Find Ruby

	      This module finds if Ruby is installed and determines where  the
	      include files and libraries are. Ruby 1.8 and 1.9 are supported.

	      The  minimum required version of Ruby can be specified using the
	      standard syntax, e.g. find_package(Ruby 1.8)

	      It also determines what the name of the library  is.  This  code
	      sets the following variables:

		RUBY_EXECUTABLE	  = full path to the ruby binary
		RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library
		RUBY_LIBRARY	  = full path to the ruby library
		RUBY_VERSION	  = the version of ruby which was found, e.g. "1.8.7"
		RUBY_FOUND	  = set to true if ruby ws found successfully

		RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it

       FindSDL
	      Locate SDL library

	      This module defines

		SDL_LIBRARY, the name of the library to link against
		SDL_FOUND, if false, do not try to link to SDL
		SDL_INCLUDE_DIR, where to find SDL.h
		SDL_VERSION_STRING, human-readable string containing the version of SDL

	      This module responds to the the flag:

		SDL_BUILDING_LIBRARY
		  If this is defined, then no SDL_main will be linked in because
		  only applications need main().
		  Otherwise, it is assumed you are building an application and this
		  module will attempt to locate and set the the proper link flags
		  as part of the returned SDL_LIBRARY variable.

	      Don't forget to include SDLmain.h and SDLmain.m your project for
	      the OS X framework based version. (Other versions link to -lSDL‐
	      main  which  this	 module will try to find on your behalf.) Also
	      for OS X, this module  will  automatically  add  the  -framework
	      Cocoa on your behalf.

	      Additional  Note:	 If  you see an empty SDL_LIBRARY_TEMP in your
	      configuration and no SDL_LIBRARY, it means CMake	did  not  find
	      your  SDL	 library (SDL.dll, libsdl.so, SDL.framework, etc). Set
	      SDL_LIBRARY_TEMP to point to your	 SDL  library,	and  configure
	      again.  Similarly,  if  you  see	an  empty SDLMAIN_LIBRARY, you
	      should set this value as appropriate. These values are  used  to
	      generate	the  final SDL_LIBRARY variable, but when these values
	      are unset, SDL_LIBRARY does not get created.

	      $SDLDIR is an environment variable that would correspond to  the
	      ./configure  --prefix=$SDLDIR  used  in  building SDL. l.e.galup
	      9-20-02

	      Modified by Eric Wing.  Added  code  to  assist  with  automated
	      building	by  using environmental variables and providing a more
	      controlled/consistent search behavior. Added  new	 modifications
	      to recognize OS X frameworks and additional Unix paths (FreeBSD,
	      etc). Also corrected the header search path to  follow  "proper"
	      SDL  guidelines.	Added  a search for SDLmain which is needed by
	      some platforms. Added a search for threads which	is  needed  by
	      some platforms. Added needed compile switches for MinGW.

	      On  OSX,	this will prefer the Framework version (if found) over
	      others. People will have to manually change the cache values  of
	      SDL_LIBRARY to override this selection or set the CMake environ‐
	      ment CMAKE_INCLUDE_PATH to modify the search paths.

	      Note that the header path has changed  from  SDL/SDL.h  to  just
	      SDL.h  This  needed to change because "proper" SDL convention is
	      #include "SDL.h", not <SDL/SDL.h>. This is done for  portability
	      reasons  because not all systems place things in SDL/ (see Free‐
	      BSD).

       FindSDL_image
	      Locate SDL_image library

	      This module defines:

		SDL_IMAGE_LIBRARIES, the name of the library to link against
		SDL_IMAGE_INCLUDE_DIRS, where to find the headers
		SDL_IMAGE_FOUND, if false, do not try to link against
		SDL_IMAGE_VERSION_STRING - human-readable string containing the version of SDL_image

	      For backward compatiblity the following variables are also set:

		SDLIMAGE_LIBRARY (same value as SDL_IMAGE_LIBRARIES)
		SDLIMAGE_INCLUDE_DIR (same value as SDL_IMAGE_INCLUDE_DIRS)
		SDLIMAGE_FOUND (same value as SDL_IMAGE_FOUND)

	      $SDLDIR is an environment variable that would correspond to  the
	      ./configure --prefix=$SDLDIR used in building SDL.

	      Created  by  Eric Wing. This was influenced by the FindSDL.cmake
	      module, but with modifications to recognize OS X frameworks  and
	      additional Unix paths (FreeBSD, etc).

       FindSDL_mixer
	      Locate SDL_mixer library

	      This module defines:

		SDL_MIXER_LIBRARIES, the name of the library to link against
		SDL_MIXER_INCLUDE_DIRS, where to find the headers
		SDL_MIXER_FOUND, if false, do not try to link against
		SDL_MIXER_VERSION_STRING - human-readable string containing the version of SDL_mixer

	      For backward compatiblity the following variables are also set:

		SDLMIXER_LIBRARY (same value as SDL_MIXER_LIBRARIES)
		SDLMIXER_INCLUDE_DIR (same value as SDL_MIXER_INCLUDE_DIRS)
		SDLMIXER_FOUND (same value as SDL_MIXER_FOUND)

	      $SDLDIR  is an environment variable that would correspond to the
	      ./configure --prefix=$SDLDIR used in building SDL.

	      Created by Eric Wing. This was influenced by  the	 FindSDL.cmake
	      module,  but with modifications to recognize OS X frameworks and
	      additional Unix paths (FreeBSD, etc).

       FindSDL_net
	      Locate SDL_net library

	      This module defines:

		SDL_NET_LIBRARIES, the name of the library to link against
		SDL_NET_INCLUDE_DIRS, where to find the headers
		SDL_NET_FOUND, if false, do not try to link against
		SDL_NET_VERSION_STRING - human-readable string containing the version of SDL_net

	      For backward compatiblity the following variables are also set:

		SDLNET_LIBRARY (same value as SDL_NET_LIBRARIES)
		SDLNET_INCLUDE_DIR (same value as SDL_NET_INCLUDE_DIRS)
		SDLNET_FOUND (same value as SDL_NET_FOUND)

	      $SDLDIR is an environment variable that would correspond to  the
	      ./configure --prefix=$SDLDIR used in building SDL.

	      Created  by  Eric Wing. This was influenced by the FindSDL.cmake
	      module, but with modifications to recognize OS X frameworks  and
	      additional Unix paths (FreeBSD, etc).

       FindSDL_sound
	      Locates the SDL_sound library

	      This  module depends on SDL being found and must be called AFTER
	      FindSDL.cmake is called.

	      This module defines

		SDL_SOUND_INCLUDE_DIR, where to find SDL_sound.h
		SDL_SOUND_FOUND, if false, do not try to link to SDL_sound
		SDL_SOUND_LIBRARIES, this contains the list of libraries that you need
		  to link against. This is a read-only variable and is marked INTERNAL.
		SDL_SOUND_EXTRAS, this is an optional variable for you to add your own
		  flags to SDL_SOUND_LIBRARIES. This is prepended to SDL_SOUND_LIBRARIES.
		  This is available mostly for cases this module failed to anticipate for
		  and you must add additional flags. This is marked as ADVANCED.
		SDL_SOUND_VERSION_STRING, human-readable string containing the version of SDL_sound

	      This  module  also  defines  (but	 you  shouldn't	 need  to  use
	      directly)

		 SDL_SOUND_LIBRARY, the name of just the SDL_sound library you would link
		 against. Use SDL_SOUND_LIBRARIES for you link instructions and not this one.

	      And might define the following as needed

		 MIKMOD_LIBRARY
		 MODPLUG_LIBRARY
		 OGG_LIBRARY
		 VORBIS_LIBRARY
		 SMPEG_LIBRARY
		 FLAC_LIBRARY
		 SPEEX_LIBRARY

	      Typically,  you should not use these variables directly, and you
	      should use SDL_SOUND_LIBRARIES which contains  SDL_SOUND_LIBRARY
	      and  the	other audio libraries (if needed) to successfully com‐
	      pile on your system.

	      Created by Eric Wing. This module is a bit more complicated than
	      the  other FindSDL* family modules. The reason is that SDL_sound
	      can be compiled in a large variety of different ways  which  are
	      independent  of platform. SDL_sound may dynamically link against
	      other 3rd party libraries to get additional codec support,  such
	      as  Ogg  Vorbis, SMPEG, ModPlug, MikMod, FLAC, Speex, and poten‐
	      tially others. Under some	 circumstances	which  I  don't	 fully
	      understand,  there  seems	 to  be	 a  requirement that dependent
	      libraries of libraries you use must also	be  explicitly	linked
	      against  in  order  to  successfully compile. SDL_sound does not
	      currently have any system in place to know how it was  compiled.
	      So  this	CMake  module does the hard work in trying to discover
	      which 3rd party libraries are required for  building  (if	 any).
	      This module uses a brute force approach to create a test program
	      that uses SDL_sound, and then tries to build it.	If  the	 build
	      fails, it parses the error output for known symbol names to fig‐
	      ure out which libraries are needed.

	      Responds to the $SDLDIR and $SDLSOUNDDIR environmental  variable
	      that  would  correspond to the ./configure --prefix=$SDLDIR used
	      in building SDL.

	      On OSX, this will prefer the Framework version (if  found)  over
	      others.  People will have to manually change the cache values of
	      SDL_LIBRARY to override this selectionor set the CMake  environ‐
	      ment CMAKE_INCLUDE_PATH to modify the search paths.

       FindSDL_ttf
	      Locate SDL_ttf library

	      This module defines:

		SDL_TTF_LIBRARIES, the name of the library to link against
		SDL_TTF_INCLUDE_DIRS, where to find the headers
		SDL_TTF_FOUND, if false, do not try to link against
		SDL_TTF_VERSION_STRING - human-readable string containing the version of SDL_ttf

	      For backward compatiblity the following variables are also set:

		SDLTTF_LIBRARY (same value as SDL_TTF_LIBRARIES)
		SDLTTF_INCLUDE_DIR (same value as SDL_TTF_INCLUDE_DIRS)
		SDLTTF_FOUND (same value as SDL_TTF_FOUND)

	      $SDLDIR  is an environment variable that would correspond to the
	      ./configure --prefix=$SDLDIR used in building SDL.

	      Created by Eric Wing. This was influenced by  the	 FindSDL.cmake
	      module,  but with modifications to recognize OS X frameworks and
	      additional Unix paths (FreeBSD, etc).

       FindSWIG
	      Find SWIG

	      This module finds an installed  SWIG.   It  sets	the  following
	      variables:

		SWIG_FOUND - set to true if SWIG is found
		SWIG_DIR - the directory where swig is installed
		SWIG_EXECUTABLE - the path to the swig executable
		SWIG_VERSION   - the version number of the swig executable

	      The  minimum required version of SWIG can be specified using the
	      standard syntax, e.g. find_package(SWIG 1.1)

	      All information is collected from	 the  SWIG_EXECUTABLE  so  the
	      version  to  be  found  can  be changed from the command line by
	      means of setting SWIG_EXECUTABLE

       FindSelfPackers
	      Find upx

	      This module looks for some  executable  packers  (i.e.  software
	      that   compress  executables  or	shared	libs  into  on-the-fly
	      self-extracting executables or shared libs. Examples:

		UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html

       FindSquish
	      -- Typical Use

	      This module can be used to find Squish.  Currently  Squish  ver‐
	      sions 3 and 4 are supported.

		SQUISH_FOUND			If false, don't try to use Squish
		SQUISH_VERSION			The full version of Squish found
		SQUISH_VERSION_MAJOR		The major version of Squish found
		SQUISH_VERSION_MINOR		The minor version of Squish found
		SQUISH_VERSION_PATCH		The patch version of Squish found

		SQUISH_INSTALL_DIR		The Squish installation directory (containing bin, lib, etc)
		SQUISH_SERVER_EXECUTABLE	The squishserver executable
		SQUISH_CLIENT_EXECUTABLE	The squishrunner executable

		SQUISH_INSTALL_DIR_FOUND	Was the install directory found?
		SQUISH_SERVER_EXECUTABLE_FOUND	Was the server executable found?
		SQUISH_CLIENT_EXECUTABLE_FOUND	Was the client executable found?

	      It  provides  the	 function  squish_v4_add_test()	 for  adding a
	      squish test to cmake using Squish 4.x:

		 squish_v4_add_test(cmakeTestName AUT targetName SUITE suiteName TEST squishTestName
				 [SETTINGSGROUP group] [PRE_COMMAND command] [POST_COMMAND command] )

	      The arguments have the following meaning:

		 cmakeTestName: this will be used as the first argument for add_test()
		 AUT targetName: the name of the cmake target which will be used as AUT, i.e. the
				 executable which will be tested.
		 SUITE suiteName: this is either the full path to the squish suite, or just the
				  last directory of the suite, i.e. the suite name. In this case
				  the CMakeLists.txt which calls squish_add_test() must be located
				  in the parent directory of the suite directory.
		 TEST squishTestName: the name of the squish test, i.e. the name of the subdirectory
				      of the test inside the suite directory.
		 SETTINGSGROUP group: if specified, the given settings group will be used for executing the test.
				      If not specified, the groupname will be "CTest_<username>"
		 PRE_COMMAND command:  if specified, the given command will be executed before starting the squish test.
		 POST_COMMAND command: same as PRE_COMMAND, but after the squish test has been executed.

		 enable_testing()
		 find_package(Squish 4.0)
		 if (SQUISH_FOUND)
		    squish_v4_add_test(myTestName AUT myApp SUITE ${CMAKE_SOURCE_DIR}/tests/mySuite TEST someSquishTest SETTINGSGROUP myGroup )
		 endif ()

	      For users of Squish version 3.x the  macro  squish_v3_add_test()
	      is provided:

		 squish_v3_add_test(testName applicationUnderTest testCase envVars testWrapper)
		 Use this macro to add a test using Squish 3.x.

		enable_testing()
		find_package(Squish)
		if (SQUISH_FOUND)
		  squish_v3_add_test(myTestName myApplication testCase envVars testWrapper)
		endif ()

	      macro   SQUISH_ADD_TEST(testName	applicationUnderTest  testCase
	      envVars testWrapper)

		 This is deprecated. Use SQUISH_V3_ADD_TEST() if you are using Squish 3.x instead.

       FindSubversion
	      Extract information from a subversion working copy

	      The module defines the following variables:

		Subversion_SVN_EXECUTABLE - path to svn command line client
		Subversion_VERSION_SVN - version of svn command line client
		Subversion_FOUND - true if the command line client was found
		SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons

	      The minimum required version  of	Subversion  can	 be  specified
	      using the standard syntax, e.g. find_package(Subversion 1.4)

	      If  the  command	line client executable is found two macros are
	      defined:

		Subversion_WC_INFO(<dir> <var-prefix>)
		Subversion_WC_LOG(<dir> <var-prefix>)

	      Subversion_WC_INFO extracts information of a subversion  working
	      copy at a given location. This macro defines the following vari‐
	      ables:

		<var-prefix>_WC_URL - url of the repository (at <dir>)
		<var-prefix>_WC_ROOT - root url of the repository
		<var-prefix>_WC_REVISION - current revision
		<var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
		<var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
		<var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
		<var-prefix>_WC_INFO - output of command `svn info <dir>'

	      Subversion_WC_LOG retrieves the log message of the base revision
	      of  a  subversion	 working  copy at a given location. This macro
	      defines the variable:

		<var-prefix>_LAST_CHANGED_LOG - last log of base revision

	      Example usage:

		find_package(Subversion)
		if(SUBVERSION_FOUND)
		  Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
		  message("Current revision is ${Project_WC_REVISION}")
		  Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
		  message("Last changed log is ${Project_LAST_CHANGED_LOG}")
		endif()

       FindTCL
	      TK_INTERNAL_PATH was removed.

	      This module finds if Tcl is installed and determines  where  the
	      include  files  and  libraries  are. It also determines what the
	      name of the library is. This code sets the following variables:

		TCL_FOUND	       = Tcl was found
		TK_FOUND	       = Tk was found
		TCLTK_FOUND	       = Tcl and Tk were found

	      In an effort to remove some clutter and clear up some issues for
	      people  who  are	not necessarily Tcl/Tk gurus/developpers, some
	      variables were moved or removed. Changes compared to  CMake  2.4
	      are:

		 => they were only useful for people writing Tcl/Tk extensions.
		 => these libs are not packaged by default with Tcl/Tk distributions.
		    Even when Tcl/Tk is built from source, several flavors of debug libs
		    are created and there is no real reason to pick a single one
		    specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
		    Let's leave that choice to the user by allowing him to assign
		    TCL_LIBRARY to any Tcl library, debug or not.
		 => this ended up being only a Win32 variable, and there is a lot of
		    confusion regarding the location of this file in an installed Tcl/Tk
		    tree anyway (see 8.5 for example). If you need the internal path at
		    this point it is safer you ask directly where the *source* tree is
		    and dig from there.

       FindTIFF
	      Find TIFF library

	      Find the native TIFF includes and library This module defines

		TIFF_INCLUDE_DIR, where to find tiff.h, etc.
		TIFF_LIBRARIES, libraries to link against to use TIFF.
		TIFF_FOUND, If false, do not try to use TIFF.

	      also defined, but not for general use are

		TIFF_LIBRARY, where to find the TIFF library.

       FindTclStub
	      TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.

	      This module finds Tcl stub libraries. It first finds Tcl include
	      files and libraries by calling FindTCL.cmake. How to Use the Tcl
	      Stubs Library:

		 http://tcl.activestate.com/doc/howto/stubs.html

	      Using Stub Libraries:

		 http://safari.oreilly.com/0130385603/ch48lev1sec3

	      This code sets the following variables:

		TK_STUB_LIBRARY	       = path to Tk stub library
		TTK_STUB_LIBRARY       = path to ttk stub library

	      name of the library is. This code sets the following variables:

		TCLSH_FOUND = TRUE if tclsh has been found
		TCL_TCLSH = the path to the tclsh executable

	      In cygwin, look for the cygwin version first.  Don't look for it
	      later to avoid finding the cygwin version on a Win32 build.

       FindThreads
	      This module determines the thread library of the system.

	      The following variables are set

		CMAKE_THREAD_LIBS_INIT	   - the thread library

	      VTK:

		VTK_DIR	 - The directory containing VTKConfig.cmake.
			   This is either the root of the build tree,
			   or the lib/vtk directory.  This is the
			   only cache entry.

	      The  following  variables are set for backward compatibility and
	      should not be used in new code:

		USE_VTK_FILE - The full path to the UseVTK.cmake file.

       Findosg

	      NOTE:  It	 is  highly recommended that you use the new FindOpen‐
	      SceneGraph.cmake introduced in CMake 2.6.3 and not use this Find
	      module directly.

	      This  is	part of the Findosg* suite used to find OpenSceneGraph
	      components. Each component is separate and you must  opt	in  to
	      each  module. You must also opt into OpenGL and OpenThreads (and
	      Producer if needed) as these modules won't do it for  you.  This
	      is  to  allow you control over your own system piece by piece in
	      case you need to opt out of certain  components  or  change  the
	      Find  behavior  for  a  particular  module  (perhaps because the
	      default FindOpenGL.cmake module doesn't work with your system as
	      an  example).  If	 you want to use a more convenient module that
	      includes everything, use the FindOpenSceneGraph.cmake instead of
	      the Findosg*.cmake modules.

       FindwxWidgets
	      Find a wxWidgets (a.k.a., wxWindows) installation.

	      This  module  finds  if  wxWidgets  is  installed	 and selects a
	      default configuration to use. wxWidgets is a modular library. To
	      specify  the modules that you will use, you need to name them as
	      components to the package:

	      find_package(wxWidgets COMPONENTS core base ...)

	      There are two search branches: a windows style and a unix style.
	      For windows, the following variables are searched for and set to
	      defaults in  case	 of  multiple  choices.	 Change	 them  if  the
	      defaults are not desired (i.e., these are the only variables you
	      should change to select a configuration):

		wxWidgets_ROOT_DIR	- Base wxWidgets directory
					  (e.g., C:/wxWidgets-2.6.3).
		wxWidgets_LIB_DIR	- Path to wxWidgets libraries
					  (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
		wxWidgets_CONFIGURATION - Configuration to use
					  (e.g., msw, mswd, mswu, mswunivud, etc.)
		wxWidgets_EXCLUDE_COMMON_LIBRARIES
					- Set to TRUE to exclude linking of
					  commonly required libs (e.g., png tiff
					  jpeg zlib regex expat).

	      For unix style it uses the wx-config  utility.  You  can	select
	      between  debug/release,  unicode/ansi,  universal/non-universal,
	      and static/shared in the QtDialog or ccmake interfaces by	 turn‐
	      ing ON/OFF the following variables:

		wxWidgets_USE_DEBUG
		wxWidgets_USE_UNICODE
		wxWidgets_USE_UNIVERSAL
		wxWidgets_USE_STATIC

	      There  is also a wxWidgets_CONFIG_OPTIONS variable for all other
	      options that need to be passed to	 the  wx-config	 utility.  For
	      example,	to  use the base toolkit found in the /usr/local path,
	      set the variable (before calling the  FIND_PACKAGE  command)  as
	      such:

		set(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr)

	      The  following  are set after the configuration is done for both
	      windows and unix style:

		wxWidgets_FOUND		   - Set to TRUE if wxWidgets was found.
		wxWidgets_INCLUDE_DIRS	   - Include directories for WIN32
					     i.e., where to find "wx/wx.h" and
					     "wx/setup.h"; possibly empty for unices.
		wxWidgets_LIBRARIES	   - Path to the wxWidgets libraries.
		wxWidgets_LIBRARY_DIRS	   - compile time link dirs, useful for
					     rpath on UNIX. Typically an empty string
					     in WIN32 environment.
		wxWidgets_DEFINITIONS	   - Contains defines required to compile/link
					     against WX, e.g. WXUSINGDLL
		wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link
					     against WX debug builds, e.g. __WXDEBUG__
		wxWidgets_CXX_FLAGS	   - Include dirs and compiler flags for
					     unices, empty on WIN32. Essentially
					     "`wx-config --cxxflags`".
		wxWidgets_USE_FILE	   - Convenience include file.

	      Sample usage:

		 # Note that for MinGW users the order of libs is important!
		 find_package(wxWidgets COMPONENTS net gl core base)
		 if(wxWidgets_FOUND)
		   include(${wxWidgets_USE_FILE})
		   # and for each of your dependent executable/library targets:
		   target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})
		 endif()

	      If wxWidgets is required (i.e., not an optional part):

		 find_package(wxWidgets REQUIRED net gl core base)
		 include(${wxWidgets_USE_FILE})
		 # and for each of your dependent executable/library targets:
		 target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})

       FindwxWindows
	      Find wxWindows (wxWidgets) installation

	      This module finds if wxWindows/wxWidgets is installed and deter‐
	      mines  where the include files and libraries are. It also deter‐
	      mines what the name of the library is. Please note this file  is
	      DEPRECATED  and  replaced by FindwxWidgets.cmake. This code sets
	      the following variables:

		WXWINDOWS_FOUND	    = system has WxWindows
		WXWINDOWS_LIBRARIES = path to the wxWindows libraries
				      on Unix/Linux with additional
				      linker flags from
				      "wx-config --libs"
		CMAKE_WXWINDOWS_CXX_FLAGS  = Compiler flags for wxWindows,
					     essentially "`wx-config --cxxflags`"
					     on Linux
		WXWINDOWS_INCLUDE_DIR	   = where to find "wx/wx.h" and "wx/setup.h"
		WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on
					      Unix
		WXWINDOWS_DEFINITIONS	   = extra defines

	      OPTIONS If you need OpenGL support please

		set(WXWINDOWS_USE_GL 1)

	      in your CMakeLists.txt *before* you include this file.

		HAVE_ISYSTEM	  - true required to replace -I by -isystem on g++

	      For convenience include Use_wxWindows.cmake  in  your  project's
	      CMakeLists.txt		 using		  include(${CMAKE_CUR‐
	      RENT_LIST_DIR}/Use_wxWindows.cmake).

	      USAGE

		set(WXWINDOWS_USE_GL 1)
		find_package(wxWindows)

	      NOTES wxWidgets 2.6.x is supported for  monolithic  builds  e.g.

       FortranCInterface
	      Fortran/C Interface Detection

	      This module automatically detects the API by which C and Fortran
	      languages	 interact.   Variables	indicate  if  the  mangling is
	      found:

		 FortranCInterface_GLOBAL_FOUND = Global subroutines and functions
		 FortranCInterface_MODULE_FOUND = Module subroutines and functions
						  (declared by "MODULE PROCEDURE")

	      A function is provided to generate a C  header  file  containing
	      macros to mangle symbol names:

		 FortranCInterface_HEADER(<file>
					  [MACRO_NAMESPACE <macro-ns>]
					  [SYMBOL_NAMESPACE <ns>]
					  [SYMBOLS [<module>:]<function> ...])

	      It generates in <file> definitions of the following macros:

		 #define FortranCInterface_GLOBAL (name,NAME) ...
		 #define FortranCInterface_GLOBAL_(name,NAME) ...
		 #define FortranCInterface_MODULE (mod,name, MOD,NAME) ...
		 #define FortranCInterface_MODULE_(mod,name, MOD,NAME) ...

	      These  macros mangle four categories of Fortran symbols, respec‐
	      tively:

		 - Global symbols without '_': call mysub()
		 - Global symbols with '_'   : call my_sub()
		 - Module symbols without '_': use mymod; call mysub()
		 - Module symbols with '_'   : use mymod; call my_sub()

	      If mangling for a category is not known, its macro is left unde‐
	      fined. All macros require raw names in both lower case and upper
	      case. The MACRO_NAMESPACE option replaces the default "FortranC‐
	      Interface_" prefix with a given namespace "<macro-ns>".

	      The  SYMBOLS option lists symbols to mangle automatically with C
	      preprocessor definitions:

		 <function>	     ==> #define <ns><function> ...
		 <module>:<function> ==> #define <ns><module>_<function> ...

	      If the mangling for some symbol is not known then no  preproces‐
	      sor  definition is created, and a warning is displayed. The SYM‐
	      BOL_NAMESPACE option prefixes all preprocessor definitions  gen‐
	      erated by the SYMBOLS option with a given namespace "<ns>".

	      Example usage:

		 include(FortranCInterface)
		 FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_")

	      This  creates  a	"FC.h"	header	that  defines  mangling macros
	      FC_GLOBAL(), FC_GLOBAL_(), FC_MODULE(), and FC_MODULE_().

	      Example usage:

		 include(FortranCInterface)
		 FortranCInterface_HEADER(FCMangle.h
					  MACRO_NAMESPACE "FC_"
					  SYMBOL_NAMESPACE "FC_"
					  SYMBOLS mysub mymod:my_sub)

	      This creates a "FCMangle.h" header that defines the same	FC_*()
	      mangling	macros	as the previous example plus preprocessor sym‐
	      bols FC_mysub and FC_mymod_my_sub.

	      Another function is provided to  verify  that  the  Fortran  and
	      C/C++ compilers work together:

		 FortranCInterface_VERIFY([CXX] [QUIET])

	      It  tests	 whether  a simple test executable using Fortran and C
	      (and C++ when the CXX option is given) compiles and  links  suc‐
	      cessfully.  The  result is stored in the cache entry FortranCIn‐
	      terface_VERIFIED_C (or FortranCInterface_VERIFIED_CXX if CXX  is
	      given)  as  a boolean. If the check fails and QUIET is not given
	      the function terminates with a  FATAL_ERROR  message  describing
	      the problem.  The purpose of this check is to stop a build early
	      for incompatible compiler combinations.  The test	 is  built  in
	      the Release configuration.

	      FortranCInterface	 is  aware  of possible GLOBAL and MODULE man‐
	      glings for many Fortran  compilers,  but	it  also  provides  an
	      interface to specify new possible manglings.  Set the variables

		 FortranCInterface_GLOBAL_SYMBOLS
		 FortranCInterface_MODULE_SYMBOLS

	      before  including	 FortranCInterface to specify manglings of the
	      symbols  "MySub",	 "My_Sub",  "MyModule:MySub",	and   "My_Mod‐
	      ule:My_Sub". For example, the code:

		 set(FortranCInterface_GLOBAL_SYMBOLS mysub_ my_sub__ MYSUB_)
		   #				      ^^^^^  ^^^^^^   ^^^^^
		 set(FortranCInterface_MODULE_SYMBOLS
		     __mymodule_MOD_mysub __my_module_MOD_my_sub)
		   #   ^^^^^^^^	    ^^^^^   ^^^^^^^^^	  ^^^^^^
		 include(FortranCInterface)

	      tells  FortranCInterface	to  try	 given	GLOBAL and MODULE man‐
	      glings. (The carets point at raw symbol  names  for  clarity  in
	      this example but are not needed.)

       GNUInstallDirs
	      Define GNU standard installation directories

	      Provides	install	 directory  variables as defined for GNU soft‐
	      ware:

		http://www.gnu.org/prep/standards/html_node/Directory-Variables.html

	      Inclusion of this module defines the following variables:

		CMAKE_INSTALL_<dir>	 - destination for files of a given type
		CMAKE_INSTALL_FULL_<dir> - corresponding absolute path

	      where <dir> is one of:

		BINDIR		 - user executables (bin)
		SBINDIR		 - system admin executables (sbin)
		LIBEXECDIR	 - program executables (libexec)
		SYSCONFDIR	 - read-only single-machine data (etc)
		SHAREDSTATEDIR	 - modifiable architecture-independent data (com)
		LOCALSTATEDIR	 - modifiable single-machine data (var)
		LIBDIR		 - object code libraries (lib or lib64 or lib/<multiarch-tuple> on Debian)
		INCLUDEDIR	 - C header files (include)
		OLDINCLUDEDIR	 - C header files for non-gcc (/usr/include)
		DATAROOTDIR	 - read-only architecture-independent data root (share)
		DATADIR		 - read-only architecture-independent data (DATAROOTDIR)
		INFODIR		 - info documentation (DATAROOTDIR/info)
		LOCALEDIR	 - locale-dependent data (DATAROOTDIR/locale)
		MANDIR		 - man documentation (DATAROOTDIR/man)
		DOCDIR		 - documentation root (DATAROOTDIR/doc/PROJECT_NAME)

	      Each CMAKE_INSTALL_<dir> value may be passed to the  DESTINATION
	      options  of  install() commands for the corresponding file type.
	      If the includer does not define a value the above-shown  default
	      will  be used and the value will appear in the cache for editing
	      by the user. Each	 CMAKE_INSTALL_FULL_<dir>  value  contains  an
	      absolute	path constructed from the corresponding destination by
	      prepending (if necessary) the value of CMAKE_INSTALL_PREFIX.

       GenerateExportHeader
	      Function for generation of export macros for libraries

	      This module provides the function	 GENERATE_EXPORT_HEADER()  and
	      the accompanying ADD_COMPILER_EXPORT_FLAGS() function.

	      The  GENERATE_EXPORT_HEADER  function  can be used to generate a
	      file suitable for preprocessor inclusion which  contains	EXPORT
	      macros to be used in library classes.

	      GENERATE_EXPORT_HEADER( LIBRARY_TARGET

			   [BASE_NAME <base_name>]
			   [EXPORT_MACRO_NAME <export_macro_name>]
			   [EXPORT_FILE_NAME <export_file_name>]
			   [DEPRECATED_MACRO_NAME <deprecated_macro_name>]
			   [NO_EXPORT_MACRO_NAME <no_export_macro_name>]
			   [STATIC_DEFINE <static_define>]
			   [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>]
			   [DEFINE_NO_DEPRECATED]
			   [PREFIX_NAME <prefix_name>]

	      )

	      ADD_COMPILER_EXPORT_FLAGS( [<output_variable>] )

	      By  default  GENERATE_EXPORT_HEADER() generates macro names in a
	      file name determined by the name of the  library.	 The  ADD_COM‐
	      PILER_EXPORT_FLAGS    function   adds   -fvisibility=hidden   to
	      CMAKE_CXX_FLAGS if supported, and is a no-op  on	Windows	 which
	      does  not	 need  extra compiler flags for exporting support. You
	      may   optionally	 pass	a   single   argument	to    ADD_COM‐
	      PILER_EXPORT_FLAGS  that	will  be  populated  with the required
	      CXX_FLAGS required to enable visibility  support	for  the  com‐
	      piler/architecture in use.

	      This  means  that in the simplest case, users of these functions
	      will be equivalent to:

		 add_compiler_export_flags()
		 add_library(somelib someclass.cpp)
		 generate_export_header(somelib)
		 install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR})
		 install(FILES
		  someclass.h
		  ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR}
		 )

	      And in the ABI header files:

		 #include "somelib_export.h"
		 class SOMELIB_EXPORT SomeClass {
		   ...
		 };

	      The CMake fragment will generate	a  file	 in  the  ${CMAKE_CUR‐
	      RENT_BINARY_DIR}	called	somelib_export.h containing the macros
	      SOMELIB_EXPORT,	   SOMELIB_NO_EXPORT,	   SOMELIB_DEPRECATED,
	      SOMELIB_DEPRECATED_EXPORT	 and SOMELIB_DEPRECATED_NO_EXPORT. The
	      resulting file should be installed with  other  headers  in  the
	      library.

	      The BASE_NAME argument can be used to override the file name and
	      the names used for the macros

		 add_library(somelib someclass.cpp)
		 generate_export_header(somelib
		   BASE_NAME other_name
		 )

	      Generates	 a  file  called  other_name_export.h  containing  the
	      macros	  OTHER_NAME_EXPORT,	  OTHER_NAME_NO_EXPORT	   and
	      OTHER_NAME_DEPRECATED etc.

	      The BASE_NAME may be overridden by specifiying other options  in
	      the function. For example:

		 add_library(somelib someclass.cpp)
		 generate_export_header(somelib
		   EXPORT_MACRO_NAME OTHER_NAME_EXPORT
		 )

	      creates  the  macro OTHER_NAME_EXPORT instead of SOMELIB_EXPORT,
	      but other macros and the generated file name is as default.

		 add_library(somelib someclass.cpp)
		 generate_export_header(somelib
		   DEPRECATED_MACRO_NAME KDE_DEPRECATED
		 )

	      creates the macro KDE_DEPRECATED instead of SOMELIB_DEPRECATED.

	      If LIBRARY_TARGET is a static library, macros are defined	 with‐
	      out values.

	      If  the  same  sources  are  used	 to create both a shared and a
	      static library, the uppercased symbol ${BASE_NAME}_STATIC_DEFINE
	      should be used when building the static library

		 add_library(shared_variant SHARED ${lib_SRCS})
		 add_library(static_variant ${lib_SRCS})
		 generate_export_header(shared_variant BASE_NAME libshared_and_static)
		 set_target_properties(static_variant PROPERTIES
		   COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE)

	      This  will  cause	 the  export  macros to expand to nothing when
	      building the static library.

	      If   DEFINE_NO_DEPRECATED	  is   specified,   then    a	 macro
	      ${BASE_NAME}_NO_DEPRECATED  will	be  defined  This macro can be
	      used to remove deprecated code from preprocessor output.

		 option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE)
		 if (EXCLUDE_DEPRECATED)
		   set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED)
		 endif()
		 generate_export_header(somelib ${NO_BUILD_DEPRECATED})

	      And then in somelib:

		 class SOMELIB_EXPORT SomeClass
		 {
		 public:
		 #ifndef SOMELIB_NO_DEPRECATED
		   SOMELIB_DEPRECATED void oldMethod();
		 #endif
		 };

		 #ifndef SOMELIB_NO_DEPRECATED
		 void SomeClass::oldMethod() {	}
		 #endif

	      If PREFIX_NAME is specified, the argument will be used as a pre‐
	      fix to all generated macros.

	      For example:

		 generate_export_header(somelib PREFIX_NAME VTK_)

	      Generates the macros VTK_SOMELIB_EXPORT etc.

       GetPrerequisites
	      Functions to analyze and list executable file prerequisites.

	      This  module  provides functions to list the .dll, .dylib or .so
	      files that an executable or shared library file depends on. (Its
	      prerequisites.)

	      It  uses	various	 tools	to  obtain the list of required shared
	      library files:

		 dumpbin (Windows)
		 objdump (MinGW on Windows)
		 ldd (Linux/Unix)
		 otool (Mac OSX)

	      The following functions are provided by this module:

		 get_prerequisites
		 list_prerequisites
		 list_prerequisites_by_glob
		 gp_append_unique
		 is_file_executable
		 gp_item_default_embedded_path
		   (projects can override with gp_item_default_embedded_path_override)
		 gp_resolve_item
		   (projects can override with gp_resolve_item_override)
		 gp_resolved_file_type
		   (projects can override with gp_resolved_file_type_override)
		 gp_file_type

	      Requires CMake 2.6 or greater because it uses  function,	break,
	      return and PARENT_SCOPE.

		GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse>
				  <exepath> <dirs>)

	      Get  the	list of shared library files required by <target>. The
	      list in the variable named <prerequisites_var> should  be	 empty
	      on  first	 entry	to this function. On exit, <prerequisites_var>
	      will contain the list of required shared library files.

	      <target> is the full path	 to  an	 executable  file.  <prerequi‐
	      sites_var>  is  the  name	 of  a	CMake  variable to contain the
	      results. <exclude_system> must be 0 or 1 indicating  whether  to
	      include  or  exclude "system" prerequisites. If <recurse> is set
	      to 1 all prerequisites will be found recursively, if  set	 to  0
	      only  direct  prerequisites are listed. <exepath> is the path to
	      the top level executable used for @executable_path replacment on
	      the  Mac.	 <dirs>	 is  a	list of paths where libraries might be
	      found: these paths are searched first when a target without  any
	      path  info  is  given.  Then  standard system locations are also
	      searched: PATH, Framework locations, /usr/lib...

		LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])

	      Print a message listing the prerequisites of <target>.

	      <target> is the name of a shared library or executable target or
	      the  full	 path  to  a  shared  library  or  executable file. If
	      <recurse> is set to 1 all prerequisites  will  be	 found	recur‐
	      sively,  if  set	to  0  only  direct  prerequisites are listed.
	      <exclude_system> must be 0 or 1 indicating whether to include or
	      exclude "system" prerequisites. With <verbose> set to 0 only the
	      full path names of the prerequisites are printed, set to 1 extra
	      informatin will be displayed.

		LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)

	      Print  the  prerequisites of shared library and executable files
	      matching a globbing pattern. <glob_arg> is GLOB or  GLOB_RECURSE
	      and <glob_exp> is a globbing expression used with "file(GLOB" or
	      "file(GLOB_RECURSE" to retrieve a list of matching files.	 If  a
	      matching file is executable, its prerequisites are listed.

	      Any additional (optional) arguments provided are passed along as
	      the optional arguments to the list_prerequisites calls.

		GP_APPEND_UNIQUE(<list_var> <value>)

	      Append <value> to the list variable <list_var> only if the value
	      is not already in the list.

		IS_FILE_EXECUTABLE(<file> <result_var>)

	      Return  1	 in  <result_var>  if <file> is a binary executable, 0
	      otherwise.

		GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>)

	      Return the path that others should refer to the item by when the
	      item is embedded inside a bundle.

	      Override	on a per-project basis by providing a project-specific
	      gp_item_default_embedded_path_override function.

		GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var>)

	      Resolve an item into an existing full path file.

	      Override on a per-project basis by providing a  project-specific
	      gp_resolve_item_override function.

		GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>)

	      Return  the  type	 of  <file>  with  respect to <original_file>.
	      String describing type of prerequisite is returned  in  variable
	      named <type_var>.

	      Use  <exepath>  and  <dirs> if necessary to resolve non-absolute
	      <file> values -- but only for non-embedded items.

	      Possible types are:

		 system
		 local
		 embedded
		 other

	      Override on a per-project basis by providing a  project-specific
	      gp_resolved_file_type_override function.

		GP_FILE_TYPE(<original_file> <file> <type_var>)

	      Return  the  type	 of  <file>  with  respect to <original_file>.
	      String describing type of prerequisite is returned  in  variable
	      named <type_var>.

	      Possible types are:

		 system
		 local
		 embedded
		 other

       InstallRequiredSystemLibraries

	      By including this file, all library files listed in the variable
	      CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS	  will	 be   installed	  with
	      install(PROGRAMS	...) into bin for WIN32 and lib for non-WIN32.
	      If CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP is set to TRUE	before
	      including this file, then the INSTALL command is not called. The
	      user can use the variable	 CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS  to
	      use a custom install command and install them however they want.
	      If it  is	 the  MSVC  compiler,  then  the  microsoft  run  time
	      libraries	  will	 be  found  and	 automatically	added  to  the
	      CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS,     and     installed.	    If
	      CMAKE_INSTALL_DEBUG_LIBRARIES  is	 set  and  it is the MSVC com‐
	      piler, then the debug libraries are installed when available. If
	      CMAKE_INSTALL_DEBUG_LIBRARIES_ONLY  is  set  then only the debug
	      libraries are installed when both debug and release  are	avail‐
	      able.  If	 CMAKE_INSTALL_MFC_LIBRARIES  is  set then the MFC run
	      time libraries are  installed  as	 well  as  the	CRT  run  time
	      libraries.  If  CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION	is set
	      then the libraries are installed to that directory  rather  than
	      the default. If CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS is
	      NOT set, then this file warns about required files that  do  not
	      exist.  You  can	set  this variable to ON before including this
	      file to avoid  the  warning.  For	 example,  the	Visual	Studio
	      Express editions do not include the redistributable files, so if
	      you include  this	 file  on  a  machine  with  only  VS  Express
	      installed, you'll get the warning.

       MacroAddFileDependencies
	      MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)

	      Using  the  macro	 MACRO_ADD_FILE_DEPENDENCIES() is discouraged.
	      There are usually better ways to specify the  correct  dependen‐
	      cies.

	      MACRO_ADD_FILE_DEPENDENCIES(<_file>  depend_files...)  is just a
	      convenience wrapper around the OBJECT_DEPENDS source file	 prop‐
	      erty.  You  can just use set_property(SOURCE <file> APPEND PROP‐
	      ERTY OBJECT_DEPENDS depend_files) instead.

       ProcessorCount
	      ProcessorCount(var)

	      Determine the number  of	processors/cores  and  save  value  in
	      ${var}

	      Sets  the	 variable named ${var} to the number of physical cores
	      available on the machine if the information can  be  determined.
	      Otherwise it is set to 0. Currently this functionality is imple‐
	      mented for AIX, cygwin, FreeBSD, HPUX, IRIX, Linux,  Mac	OS  X,
	      QNX, Sun and Windows.

	      This  function  is guaranteed to return a positive integer (>=1)
	      if it succeeds. It returns 0 if there's  a  problem  determining
	      the processor count.

	      Example use, in a ctest -S dashboard script:

		 include(ProcessorCount)
		 ProcessorCount(N)
		 if(NOT N EQUAL 0)
		   set(CTEST_BUILD_FLAGS -j${N})
		   set(ctest_test_args ${ctest_test_args} PARALLEL_LEVEL ${N})
		 endif()

	      This function is intended to offer an approximation of the value
	      of the number of compute cores available on the current machine,
	      such  that you may use that value for parallel building and par‐
	      allel testing. It is meant  to  help  utilize  as	 much  of  the
	      machine  as  seems reasonable. Of course, knowledge of what else
	      might be running on the machine simultaneously  should  be  used
	      when  deciding  whether to request a machine's full capacity all
	      for yourself.

       SelectLibraryConfigurations

	      select_library_configurations( basename )

	      This macro takes a library base name as an  argument,  and  will
	      choose  good  values  for	 basename_LIBRARY, basename_LIBRARIES,
	      basename_LIBRARY_DEBUG, and  basename_LIBRARY_RELEASE  depending
	      on   what	  has	been   found   and   set.    If	  only	 base‐
	      name_LIBRARY_RELEASE is defined, basename_LIBRARY will be set to
	      the  release  value,  and	 basename_LIBRARY_DEBUG will be set to
	      basename_LIBRARY_DEBUG-NOTFOUND.	If only basename_LIBRARY_DEBUG
	      is defined, then basename_LIBRARY will take the debug value, and
	      basename_LIBRARY_RELEASE	  will	   be	  set	  to	 base‐
	      name_LIBRARY_RELEASE-NOTFOUND.

	      If  the  generator  supports  configuration  types,  then	 base‐
	      name_LIBRARY and basename_LIBRARIES will be set with  debug  and
	      optimized	 flags specifying the library to be used for the given
	      configuration.  If no build type has been set or	the  generator
	      in   use	does  not  support  configuration  types,  then	 base‐
	      name_LIBRARY and basename_LIBRARIES will take only  the  release
	      value, or the debug value if the release one is not set.

       SquishTestScript

	      This  script  launches  a GUI test using Squish.	You should not
	      call the script directly; instead, you should access it via  the
	      SQUISH_ADD_TEST macro that is defined in FindSquish.cmake.

	      This  script  starts the Squish server, launches the test on the
	      client, and finally stops the squish server.  If	any  of	 these
	      steps  fail  (including  if  the tests do not pass) then a fatal
	      error is raised.

       TestBigEndian
	      Define macro to determine endian type

	      Check if the system is big endian or little endian

		VARIABLE - variable to store the result to

       TestCXXAcceptsFlag
	      Test CXX compiler for a flag

	      Check if the CXX compiler accepts a flag

       TestForANSIForScope
	      Check for ANSI for scope support

	      Check if the compiler restricts the scope of variables  declared
	      in a for-init-statement to the loop body.

	      check if the compiler supports std:: on stl classes

		CMAKE_NO_STD_NAMESPACE - defined by the results

       UseEcos
	      This module defines variables and macros required to build  eCos
	      application.

	      This file contains the following macros: ECOS_ADD_INCLUDE_DIREC‐
	      TORIES() - add the eCos  include	dirs  ECOS_ADD_EXECUTABLE(name
	      source1	...   sourceN	)   -	create	 an   eCos  executable
	      ECOS_ADJUST_DIRECTORY(VAR source1 ... sourceN )  -  adjusts  the

	      add_jar(target_name

		       [SOURCES] source1 [source2 ...] [resource1 ...]
		       [INCLUDE_JARS jar1 [jar2 ...]]
		       [ENTRY_POINT entry]
		       [VERSION version]
		       [OUTPUT_NAME name]
		       [OUTPUT_DIR dir]
		      )

	      This  command creates a <target_name>.jar. It compiles the given
	      source  files  (source)  and  adds  the  given  resource	 files
	      (resource)  to  the  jar	file. If only resource files are given
	      then just a jar file is created. The list of  include  jars  are
	      added  to the classpath when compiling the java sources and also
	      to the dependencies of the  target.  INCLUDE_JARS	 also  accepts
	      other target names created by add_jar. For backwards compatibil‐
	      ity, jar files listed as sources are ignored (as they have  been
	      since the first version of this module).

	      The  default OUTPUT_DIR can also be changed by setting the vari‐
	      able CMAKE_JAVA_TARGET_OUTPUT_DIR.

	      Additional instructions:

		 To add compile flags to the target you can set these flags with
		 the following variable:

		     set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)

		 To add a path or a jar file to the class path you can do this
		 with the CMAKE_JAVA_INCLUDE_PATH variable.

		     set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)

		 To use a different output name for the target you can set it with:

		     add_jar(foobar foobar.java OUTPUT_NAME shibboleet.jar)

		 To use a different output directory than CMAKE_CURRENT_BINARY_DIR
		 you can set it with:

		     add_jar(foobar foobar.java OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)

		 To define an entry point in your jar you can set it with the ENTRY_POINT
		 named argument:

		     add_jar(example ENTRY_POINT com/examples/MyProject/Main)

		 To add a VERSION to the target output name you can set it using
		 the VERSION named argument to add_jar. This will create a jar file with the
		 name shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
		 pointing to the jar with the version information.

		     add_jar(shibboleet shibbotleet.java VERSION 1.2.0)

		  If the target is a JNI library, utilize the following commands to
		  create a JNI symbolic link:

		     set(CMAKE_JNI_TARGET TRUE)
		     add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
		     install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
		     install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})

		  If a single target needs to produce more than one jar from its
		  java source code, to prevent the accumulation of duplicate class
		  files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
		  to calling the add_jar() function:

		     set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
		     add_jar(foo foo.java)

		     set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
		     add_jar(bar bar.java)

	      Target Properties:

		 The add_jar() functions sets some target properties. You can get these
		 properties with the
		    get_property(TARGET <target_name> PROPERTY <propery_name>)
		 command.

		 INSTALL_FILES	    The files which should be installed. This is used by
				    install_jar().
		 JNI_SYMLINK	    The JNI symlink which should be installed.
				    This is used by install_jni_symlink().
		 JAR_FILE	    The location of the jar file so that you can include
				    it.
		 CLASS_DIR	    The directory where the class files can be found. For
				    example to use them with javah.

	      find_jar(<VAR>

			name | NAMES name1 [name2 ...]
			[PATHS path1 [path2 ... ENV var]]
			[VERSIONS version1 [version2]]
			[DOC "cache documentation string"]
		       )

	      This command is used to find a full path to  the	named  jar.  A
	      cache entry named by <VAR> is created to stor the result of this
	      command. If the full path to a jar is found the result is stored
	      in  the  variable	 and  the  search will not repeated unless the
	      variable is cleared. If nothing is found,	 the  result  will  be
	      <VAR>-NOTFOUND, and the search will be attempted again next time
	      find_jar is invoked with the same variable. The name of the full
	      path  to	a  file that is searched for is specified by the names
	      listed after NAMES argument. Additional search locations can  be
	      specified	 after	the  PATHS  argument. If you require special a
	      version of a jar file you can specify it with the VERSIONS argu‐
	      ment.  The argument after DOC will be used for the documentation
	      string in the cache.

	      install_jar(TARGET_NAME DESTINATION)

	      This command installs the TARGET_NAME files to the given	DESTI‐
	      NATION. It should be called in the same scope as add_jar() or it
	      will fail.

	      install_jni_symlink(TARGET_NAME DESTINATION)

	      This command installs the TARGET_NAME JNI symlinks to the	 given
	      DESTINATION.  It should be called in the same scope as add_jar()
	      or it will fail.

	      Create java documentation based on files or packages.  For  more
	      details please read the javadoc manpage.

	      There are two main signatures for create_javadoc. The first sig‐
	      nature works with package names on a path with source files:

		 Example:
		 create_javadoc(my_example_doc
		   PACKAGES com.exmaple.foo com.example.bar
		   SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
		   CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
		   WINDOWTITLE "My example"
		   DOCTITLE "<h1>My example</h1>"
		   AUTHOR TRUE
		   USE TRUE
		   VERSION TRUE
		 )

	      The second signature for create_javadoc works on a given list of
	      files.

		 create_javadoc(<VAR>
				FILES file1 [file2 ...]
				[CLASSPATH <classpath>]
				[INSTALLPATH <install path>]
				[DOCTITLE "the documentation title"]
				[WINDOWTITLE "the title of the document"]
				[AUTHOR TRUE|FALSE]
				[USE TRUE|FALSE]
				[VERSION TRUE|FALSE]
			       )

	      Example:

		 create_javadoc(my_example_doc
		   FILES ${example_SRCS}
		   CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
		   WINDOWTITLE "My example"
		   DOCTITLE "<h1>My example</h1>"
		   AUTHOR TRUE
		   USE TRUE
		   VERSION TRUE
		 )

	      Both signatures share most of the options. These options are the
	      same as what you can find in the javadoc manpage. Please look at
	      the  manpage  for	 CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE
	      and VERSION.

	      The documentation will be by default installed to

		 ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>

	      if you don't set the INSTALLPATH.

	      Defines the following macros:

		 SWIG_ADD_MODULE(name language [ files ])
		   - Define swig module with given name and specified language
		 SWIG_LINK_LIBRARIES(name [ libraries ])
		   - Link libraries to swig module

	      All  other  macros  are for internal use only. To get the actual
	      name of the swig module, use:  ${SWIG_MODULE_${name}_REAL_NAME}.
	      Set  Source files properties such as CPLUSPLUS and SWIG_FLAGS to
	      specify special behavior of SWIG. Also  global  CMAKE_SWIG_FLAGS
	      can be used to add special flags to all swig calls. Another spe‐
	      cial variable is CMAKE_SWIG_OUTDIR, it  allows  one  to  specify
	      where  to	 write	all  the  swig	generated module (swig -outdir
	      option) The name-specific variable SWIG_MODULE_<name>_EXTRA_DEPS
	      may be used to specify extra dependencies for the generated mod‐
	      ules. If the source file generated by  swig  need	 some  special
	      flag  you	 can  use  set_source_files_properties(	 ${swig_gener‐

POLICIES
       CMP0000
	      A minimum required CMake version must be specified.

	      CMake  requires  that  projects  specify the version of CMake to
	      which they have been written.  This policy has been put in place
	      so  users trying to build the project may be told when they need
	      to update their CMake.  Specifying  a  version  also  helps  the
	      project  build  with  CMake  versions newer than that specified.
	      Use the cmake_minimum_required command at the top of  your  main
	      CMakeLists.txt file:

		cmake_minimum_required(VERSION <major>.<minor>)

	      where "<major>.<minor>" is the version of CMake you want to sup‐
	      port (such as "2.6").  The command will ensure that at least the
	      given  version  of  CMake	 is running and help newer versions be
	      compatible with the project.  See documentation  of  cmake_mini‐
	      mum_required for details.

	      Note  that  the  command	invocation  must  appear in the CMake‐
	      Lists.txt file itself; a call in an included file is not	suffi‐
	      cient.   However,	 the cmake_policy command may be called to set
	      policy CMP0000 to OLD  or	 NEW  behavior	explicitly.   The  OLD
	      behavior	is to silently ignore the missing invocation.  The NEW
	      behavior is to issue an error instead of a warning.  An included
	      file  may	 set  CMP0000  explicitly to affect how this policy is
	      enforced for the main CMakeLists.txt file.

	      This policy was introduced in CMake version 2.6.0.

       CMP0001
	      CMAKE_BACKWARDS_COMPATIBILITY should no longer be used.

	      The OLD behavior is to check  CMAKE_BACKWARDS_COMPATIBILITY  and
	      present  it  to  the  user.   The	 NEW  behavior	is  to	ignore
	      CMAKE_BACKWARDS_COMPATIBILITY completely.

	      In CMake 2.4 and below the variable  CMAKE_BACKWARDS_COMPATIBIL‐
	      ITY  was	used to request compatibility with earlier versions of
	      CMake.  In CMake 2.6 and above all compatibility issues are han‐
	      dled  by	policies and the cmake_policy command.	However, CMake
	      must  still  check  CMAKE_BACKWARDS_COMPATIBILITY	 for  projects
	      written for CMake 2.4 and below.

	      This  policy  was introduced in CMake version 2.6.0.  CMake ver‐
	      sion 2.8.12 warns when the policy is not set and uses OLD behav‐
	      ior.   Use  the  cmake_policy  command  to  set it to OLD or NEW
	      explicitly.

       CMP0002
	      Logical target names must be globally unique.

	      Targets  names  created  with  add_executable,  add_library,  or
	      add_custom_target	 are logical build target names.  Logical tar‐
	      get names must be globally unique because:

		- Unique names may be referenced unambiguously both in CMake
		  code and on make tool command lines.
		- Logical names are used by Xcode and VS IDE generators
		  to produce meaningful project names for the targets.

	      The logical name of executable and library targets does not have
	      to  correspond to the physical file names built.	Consider using
	      the OUTPUT_NAME target property to create two targets  with  the
	      same physical name while keeping logical names distinct.	Custom
	      targets must simply have globally unique names (unless one  uses
	      the  global property ALLOW_DUPLICATE_CUSTOM_TARGETS with a Make‐
	      files generator).

	      This policy was introduced in CMake version 2.6.0.   CMake  ver‐
	      sion 2.8.12 warns when the policy is not set and uses OLD behav‐
	      ior.  Use the cmake_policy command to  set  it  to  OLD  or  NEW
	      explicitly.

       CMP0003
	      Libraries	 linked	 via full path no longer produce linker search
	      paths.

	      This policy affects how libraries whose full paths are NOT known
	      are  found  at link time, but was created due to a change in how
	      CMake deals with libraries whose full paths are known.  Consider
	      the code

		target_link_libraries(myexe /path/to/libA.so)

	      CMake  2.4 and below implemented linking to libraries whose full
	      paths are known by splitting them on the link line into separate
	      components  consisting of the linker search path and the library
	      name.  The example code might have produced something like

		... -L/path/to -lA ...

	      in order to link to library A.  An  analysis  was	 performed  to
	      order  multiple link directories such that the linker would find
	      library A in the desired location, but there are cases in	 which
	      this  does  not work.  CMake versions 2.6 and above use the more
	      reliable approach of passing the full path to libraries directly
	      to  the  linker  in  most	 cases.	 The example code now produces
	      something like

		... /path/to/libA.so ....

	      Unfortunately this change can break code like

		target_link_libraries(myexe /path/to/libA.so B)

	      where "B" is meant to find  "/path/to/libB.so".	This  code  is
	      wrong  because  the  user is asking the linker to find library B
	      but has not provided a linker search path (which	may  be	 added
	      with the link_directories command).  However, with the old link‐
	      ing implementation the code would work accidentally because  the
	      linker  search  path added for library A allowed library B to be
	      found.

	      In order to support projects depending on	 linker	 search	 paths
	      added  by	 linking  to  libraries with known full paths, the OLD
	      behavior for this policy will add the linker search  paths  even
	      though  they  are not needed for their own libraries.  When this
	      policy is set to OLD, CMake will produce a link line such as

		... -L/path/to /path/to/libA.so -lB ...

	      which will allow library B to be found  as  it  was  previously.
	      When  this  policy is set to NEW, CMake will produce a link line
	      such as

		... /path/to/libA.so -lB ...

	      which more accurately matches what the project specified.

	      The setting for this policy used when generating the  link  line
	      is  that	in  effect  when  the target is created by an add_exe‐
	      cutable or  add_library  command.	  For  the  example  described
	      above, the code

		cmake_policy(SET CMP0003 OLD) # or cmake_policy(VERSION 2.4)
		add_executable(myexe myexe.c)
		target_link_libraries(myexe /path/to/libA.so B)

	      will work and suppress the warning for this policy.  It may also
	      be updated to work with the corrected linking approach:

		cmake_policy(SET CMP0003 NEW) # or cmake_policy(VERSION 2.6)
		link_directories(/path/to) # needed to find library B
		add_executable(myexe myexe.c)
		target_link_libraries(myexe /path/to/libA.so B)

	      Even better, library B may be specified with a full path:

		add_executable(myexe myexe.c)
		target_link_libraries(myexe /path/to/libA.so /path/to/libB.so)

	      When all items on the link line have known paths CMake does  not
	      check this policy so it has no effect.

	      Note that the warning for this policy will be issued for at most
	      one target.  This avoids flooding users with messages for	 every
	      target  when  setting the policy once will probably fix all tar‐
	      gets.

	      This policy was introduced in CMake version 2.6.0.   CMake  ver‐
	      sion 2.8.12 warns when the policy is not set and uses OLD behav‐
	      ior.  Use the cmake_policy command to  set  it  to  OLD  or  NEW
	      explicitly.

       CMP0004
	      Libraries linked may not have leading or trailing whitespace.

	      CMake versions 2.4 and below silently removed leading and trail‐
	      ing whitespace from libraries linked with code like

		target_link_libraries(myexe " A ")

	      This could lead to subtle errors in user projects.

	      The OLD behavior for this policy is to silently  remove  leading
	      and trailing whitespace.	The NEW behavior for this policy is to
	      diagnose the existence of such whitespace as an error.  The set‐
	      ting  for	 this  policy  used when checking the library names is
	      that in effect when the target is created by  an	add_executable
	      or add_library command.

	      This  policy  was introduced in CMake version 2.6.0.  CMake ver‐
	      sion 2.8.12 warns when the policy is not set and uses OLD behav‐
	      ior.   Use  the  cmake_policy  command  to  set it to OLD or NEW
	      explicitly.

       CMP0005
	      Preprocessor definition values are now escaped automatically.

	      This policy determines whether  or  not  CMake  should  generate
	      escaped  preprocessor  definition	 values	 added via add_defini‐
	      tions.  CMake versions 2.4 and below assumed that	 only  trivial
	      values  would  be given for macros in add_definitions calls.  It
	      did not attempt to escape non-trivial values such as string lit‐
	      erals  in	 generated  build rules.  CMake versions 2.6 and above
	      support escaping of most values, but cannot assume the user  has
	      not  added  escapes already in an attempt to work around limita‐
	      tions in earlier versions.

	      The OLD behavior for this policy is to place  definition	values
	      given  to	 add_definitions directly in the generated build rules
	      without attempting to escape anything.   The  NEW	 behavior  for
	      this  policy is to generate correct escapes for all native build
	      tools automatically.  See documentation of  the  COMPILE_DEFINI‐
	      TIONS  target property for limitations of the escaping implemen‐
	      tation.

	      This policy was introduced in CMake version 2.6.0.   CMake  ver‐
	      sion 2.8.12 warns when the policy is not set and uses OLD behav‐
	      ior.  Use the cmake_policy command to  set  it  to  OLD  or  NEW
	      explicitly.

       CMP0006
	      Installing MACOSX_BUNDLE targets requires a BUNDLE DESTINATION.

	      This policy determines whether the install(TARGETS) command must
	      be given a BUNDLE DESTINATION when asked	to  install  a	target
	      with  the	 MACOSX_BUNDLE	property set.  CMake 2.4 and below did
	      not distinguish application bundles from normal executables when
	      installing  targets.   CMake 2.6 provides a BUNDLE option to the
	      install(TARGETS) command that specifies rules specific to appli‐
	      cation bundles on the Mac.  Projects should use this option when
	      installing a target with the MACOSX_BUNDLE property set.

	      The OLD behavior for this policy is to fall back to the  RUNTIME
	      DESTINATION  if  a  BUNDLE  DESTINATION  is  not given.  The NEW
	      behavior for this policy is to produce an error if a bundle tar‐
	      get is installed without a BUNDLE DESTINATION.

	      This  policy  was introduced in CMake version 2.6.0.  CMake ver‐
	      sion 2.8.12 warns when the policy is not set and uses OLD behav‐
	      ior.   Use  the  cmake_policy  command  to  set it to OLD or NEW
	      explicitly.

       CMP0007
	      list command no longer ignores empty elements.

	      This policy determines whether  the  list	 command  will	ignore
	      empty  elements  in  the list. CMake 2.4 and below list commands
	      ignored all empty elements in the	 list.	 For  example,	a;b;;c
	      would  have length 3 and not 4. The OLD behavior for this policy
	      is to ignore empty list elements. The NEW behavior for this pol‐
	      icy is to correctly count empty elements in a list.

	      This  policy  was introduced in CMake version 2.6.0.  CMake ver‐
	      sion 2.8.12 warns when the policy is not set and uses OLD behav‐

	      Libraries linked by full-path must have  a  valid	 library  file
	      name.

	      In CMake 2.4 and below it is possible to write code like

		target_link_libraries(myexe /full/path/to/somelib)

	      where "somelib" is supposed to be a valid library file name such
	      as "libsomelib.a" or  "somelib.lib".   For  Makefile  generators
	      this  produces  an error at build time because the dependency on
	      the full path cannot be found.  For VS IDE and Xcode  generators
	      this  used  to work by accident because CMake would always split
	      off the library directory and ask the linker to search  for  the
	      library by name (-lsomelib or somelib.lib).  Despite the failure
	      with Makefiles, some projects have code like this and build only
	      with VS and/or Xcode.  This version of CMake prefers to pass the
	      full path directly to the native build tool, which will fail  in
	      this case because it does not name a valid library file.

	      This  policy  determines	what to do with full paths that do not
	      appear to name a valid library file.  The OLD behavior for  this
	      policy  is  to  split the library name from the path and ask the
	      linker to search for it.	The NEW behavior for this policy is to
	      trust  the  given	 path and pass it directly to the native build
	      tool unchanged.

	      This policy was introduced in CMake version 2.6.1.   CMake  ver‐
	      sion 2.8.12 warns when the policy is not set and uses OLD behav‐

	      FILE GLOB_RECURSE calls should not follow symlinks by default.

	      In  CMake	 2.6.1 and below, FILE GLOB_RECURSE calls would follow
	      through symlinks, sometimes coming up  with  unexpectedly	 large
	      result  sets  because  of symlinks to top level directories that
	      contain hundreds of thousands of files.

	      This policy determines whether or not to follow symlinks encoun‐
	      tered during a FILE GLOB_RECURSE call. The OLD behavior for this
	      policy is to follow the symlinks. The NEW behavior for this pol‐
	      icy  is  not to follow the symlinks by default, but only if FOL‐
	      LOW_SYMLINKS is given as an additional argument to the FILE com‐
	      mand.

	      Bad variable reference syntax is an error.

	      In CMake 2.6.2 and below, incorrect  variable  reference	syntax
	      such as a missing close-brace ("${FOO") was reported but did not
	      stop processing of CMake code.  This policy determines whether a
	      bad  variable  reference is an error.  The OLD behavior for this
	      policy is to warn about the error, leave the  string  untouched,
	      and  continue.  The NEW behavior for this policy is to report an
	      error.

	      This policy was introduced in CMake version 2.6.3.   CMake  ver‐

	      Included scripts do automatic cmake_policy PUSH and POP.

	      In  CMake	 2.6.2	and  below,  CMake  Policy settings in scripts
	      loaded by the include() and find_package() commands would affect
	      the  includer.   Explicit	 invocations of cmake_policy(PUSH) and
	      cmake_policy(POP) were required to isolate  policy  changes  and
	      protect  the  includer.  While some scripts intend to affect the
	      policies of their includer, most do not.	 In  CMake  2.6.3  and
	      above,  include()	 and find_package() by default PUSH and POP an
	      entry on the policy stack around an included script, but provide
	      a	 NO_POLICY_SCOPE option to disable it.	This policy determines
	      whether or not to imply NO_POLICY_SCOPE for compatibility.   The
	      OLD  behavior  for  this	policy is to imply NO_POLICY_SCOPE for
	      include() and find_package() commands.   The  NEW	 behavior  for
	      this  policy  is	to  allow  the	commands  to  do their default
	      cmake_policy PUSH and POP.

	      This policy was introduced in CMake version 2.6.3.   CMake  ver‐
	      sion 2.8.12 warns when the policy is not set and uses OLD behav‐

	      if() recognizes numbers and boolean constants.

	      In  CMake	 versions  2.6.4 and lower the if() command implicitly
	      dereferenced arguments corresponding to  variables,  even	 those
	      named  like  numbers  or	boolean constants, except for 0 and 1.
	      Numbers and boolean constants such as true, false, yes, no,  on,
	      off,  y,	n, notfound, ignore (all case insensitive) were recog‐
	      nized in	some  cases  but  not  all.   For  example,  the  code
	      "if(TRUE)"  might	 have  evaluated  as false.  Numbers such as 2
	      were recognized only in boolean  expressions  like  "if(NOT  2)"
	      (leading	to  false)  but	 not as a single-argument like "if(2)"
	      (also leading to false). Later versions of CMake prefer to treat
	      numbers  and  boolean constants literally, so they should not be
	      used as variable names.

	      The OLD behavior for this policy is  to  implicitly  dereference
	      variables	 named	like  numbers  and  boolean constants. The NEW
	      behavior for this policy is to  recognize	 numbers  and  boolean
	      constants without dereferencing variables with such names.

	      Duplicate binary directories are not allowed.

	      CMake 2.6.3  and	below  silently	 permitted  add_subdirectory()
	      calls  to create the same binary directory multiple times.  Dur‐
	      ing build system generation files	 would	be  written  and  then
	      overwritten  in  the build tree and could lead to strange behav‐
	      ior.  CMake 2.6.4 and above explicitly detect  duplicate	binary
	      directories.   CMake  2.6.4 always considers this case an error.
	      In CMake 2.8.0 and above this policy determines whether  or  not
	      the  case	 is  an error.	The OLD behavior for this policy is to

	      or  subdirs(),  treating them as if present but empty.  In CMake
	      2.8.0 and above this policy determines whether or not  the  case
	      is  an  error.   The OLD behavior for this policy is to silently
	      ignore the problem.  The NEW behavior  for  this	policy	is  to

	      link_directories() treats paths relative to the source dir.

	      In CMake 2.8.0 and lower the link_directories()  command	passed
	      relative	paths  unchanged  to  the  linker.  In CMake 2.8.1 and
	      above the link_directories() command prefers to interpret	 rela‐
	      tive  paths  with	 respect to CMAKE_CURRENT_SOURCE_DIR, which is
	      consistent with include_directories() and other  commands.   The
	      OLD  behavior  for this policy is to use relative paths verbatim
	      in the linker command.  The NEW behavior for this policy	is  to
	      convert  relative paths to absolute paths by appending the rela‐
	      tive path to CMAKE_CURRENT_SOURCE_DIR.

	      Prefer files from the CMake module directory when including from

	      Starting	with CMake 2.8.4, if a cmake-module shipped with CMake
	      (i.e. located in the CMake module directory) calls include()  or
	      find_package(),  the files located in the CMake module directory
	      are preferred over the files in CMAKE_MODULE_PATH.   This	 makes
	      sure  that the modules belonging to CMake always get those files
	      included which they expect, and against which they  were	devel‐
	      oped  and	 tested.   In  all  other  cases,  the	files found in
	      CMAKE_MODULE_PATH still take precedence over  the	 ones  in  the
	      CMake  module  directory.	 The OLD behaviour is to always prefer
	      files from CMAKE_MODULE_PATH over files from the	CMake  modules
	      directory.

	      This  policy  was introduced in CMake version 2.8.4.  CMake ver‐

	      Ignore CMAKE_SHARED_LIBRARY_<Lang>_FLAGS variable.

	      CMake 2.8.8 and lower compiled  sources  in  SHARED  and	MODULE
	      libraries	    using    the    value    of	   the	  undocumented
	      CMAKE_SHARED_LIBRARY_<Lang>_FLAGS platform variable.  The	 vari‐
	      able contained platform-specific flags needed to compile objects
	      for shared libraries.  Typically it  included  a	flag  such  as
	      -fPIC  for  position  independent	 code  but also included other
	      flags needed on certain platforms.  CMake 2.8.9 and higher  pre‐
	      fer instead to use the POSITION_INDEPENDENT_CODE target property
	      to determine what targets should be  position  independent,  and
	      new undocumented platform variables to select flags while ignor‐
	      ing CMAKE_SHARED_LIBRARY_<Lang>_FLAGS completely.

	      The default for either approach produces	identical  compilation
	      flags,	    but	       if	a	project	      modifies
	      CMAKE_SHARED_LIBRARY_<Lang>_FLAGS from its original  value  this
	      policy determines which approach to use.

	      The OLD behavior for this policy is to ignore the POSITION_INDE‐
	      PENDENT_CODE property for all targets and use the modified value
	      of   CMAKE_SHARED_LIBRARY_<Lang>_FLAGS  for  SHARED  and	MODULE
	      libraries.

	      The   NEW	  behavior   for   this	  policy    is	  to	ignore
	      CMAKE_SHARED_LIBRARY_<Lang>_FLAGS	 whether it is modified or not
	      and honor the POSITION_INDEPENDENT_CODE target property.

	      include_directories, link_directories, and  link_libraries  com‐
	      mands  to	 expand any leftover variable references at the end of
	      the configuration step.  This was for strict compatibility  with
	      VERY  early  CMake  versions because all variable references are
	      now normally evaluated during CMake language processing.	 CMake
	      2.8.11 and higher prefer to skip the extra evaluation.

	      Automatically link Qt executables to qtmain target on Windows.

	      CMake 2.8.10 and lower required users of Qt to always specify  a
	      link  dependency	to  the	 qtmain.lib static library manually on
	      Windows.	CMake 2.8.11 gained the ability to evaluate  generator
	      expressions   while   determining	 the  link  dependencies  from
	      IMPORTED targets.	 This allows  CMake  itself  to	 automatically
	      link executables which link to Qt to the qtmain.lib library when
	      using IMPORTED Qt targets.  For applications already linking  to
	      qtmain.lib,  this	 should	 have little impact.  For applications
	      which supply their own alternative  WinMain  implementation  and
	      for applications which use the QAxServer library, this automatic
	      linking will need to be disabled as per the documentation.

	      The OLD behavior for this policy is not to link  executables  to
	      qtmain.lib  automatically when they link to the QtCore IMPORTED‐
	      target.  The NEW behavior for this policy is to link executables
	      to  qtmain.lib  automatically  when they link to QtCore IMPORTED

	      Fatal  error  on	relative  paths	 in INCLUDE_DIRECTORIES target
	      property.

	      CMake 2.8.10.2 and lower allowed the INCLUDE_DIRECTORIES	target
	      property to contain relative paths.  The base path for such rel‐
	      ative entries is	not  well  defined.   CMake  2.8.12  issues  a
	      FATAL_ERROR if the INCLUDE_DIRECTORIES property contains a rela‐
	      tive path.

	      The OLD behavior for this policy is not to warn  about  relative
	      paths  in	 the  INCLUDE_DIRECTORIES  target  property.   The NEW
	      behavior	for  this  policy  is  to  issue  a   FATAL_ERROR   if

	      INTERFACE_LINK_LIBRARIES defines the link interface.

	      CMake 2.8.11 constructed the 'link interface' of a  target  from
	      properties  matching (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CON‐
	      FIG>)?.  The modern way to specify config-sensitive  content  is
	      to use generator expressions and the IMPORTED_ prefix makes uni‐
	      form processing of the link interface with generator expressions
	      impossible.   The	 INTERFACE_LINK_LIBRARIES  target property was
	      introduced as a replacement in CMake 2.8.12. This	 new  property
	      is  named	 consistently  with the INTERFACE_COMPILE_DEFINITIONS,
	      INTERFACE_INCLUDE_DIRECTORIES   and    INTERFACE_COMPILE_OPTIONS
	      properties.   For	 in-build  targets,  CMake will use the INTER‐
	      FACE_LINK_LIBRARIES property as the source of the link interface
	      only  if	policy	CMP0022 is NEW.	 When exporting a target which
	      has this policy set to NEW,  only	 the  INTERFACE_LINK_LIBRARIES
	      property will be processed and generated for the IMPORTED target
	      by default.  A new option to the install(EXPORT) and export com‐
	      mands  allows export of the old-style properties for compatibil‐
	      ity with downstream users of CMake versions older	 than  2.8.12.
	      The  target_link_libraries  command  will no longer populate the
	      properties matching LINK_INTERFACE_LIBRARIES(_<CONFIG>)? if this
	      policy is NEW.

	      The  OLD	behavior  for  this  policy  is	 to  ignore the INTER‐
	      FACE_LINK_LIBRARIES property  for	 in-build  targets.   The  NEW
	      behavior	for this policy is to use the INTERFACE_LINK_LIBRARIES
	      property for in-build targets, and  ignore  the  old  properties
	      matching (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)?.

	      Plain and keyword	 target_link_libraries	signatures  cannot  be
	      mixed.

	      CMake  2.8.12  introduced	 the  target_link_libraries  signature
	      using the PUBLIC, PRIVATE, and INTERFACE keywords to  generalize
	      the  LINK_PUBLIC	and  LINK_PRIVATE keywords introduced in CMake
	      2.8.7.  Use of signatures with any of these  keywords  sets  the
	      link interface of a target explicitly, even if empty.  This pro‐
	      duces confusing behavior when used in combination with the  his‐
	      torical  behavior	 of the plain target_link_libraries signature.
	      For example, consider the code:

	       target_link_libraries(mylib A)
	       target_link_libraries(mylib PRIVATE B)

	      After the first line the link interface has not been set explic‐
	      itly  so CMake would use the link implementation, A, as the link
	      interface.  However, the second line sets the link interface  to
	      empty.  In order to avoid this subtle behavior CMake now prefers
	      to disallow mixing the plain  and	 keyword  signatures  of  tar‐
	      get_link_libraries for a single target.

	      The  OLD	behavior for this policy is to allow keyword and plain
	      target_link_libraries signatures to be mixed.  The NEW  behavior
	      for  this	 policy	 is  to not to allow mixing of the keyword and
	      plain signatures.

VARIABLES
VARIABLES THAT CHANGE BEHAVIOR
       BUILD_SHARED_LIBS
	      Global  flag  to cause add_library to create shared libraries if
	      on.

	      If present and true, this will cause all libraries to  be	 built
	      shared  unless  the  library  was	 explicitly  added as a static
	      library.	This variable is often added to projects as an	OPTION
	      so  that each user of a project can decide if they want to build
	      the project using shared or static libraries.

       CMAKE_ABSOLUTE_DESTINATION_FILES
	      List of files which have been installed using  an ABSOLUTE  DES‐
	      TINATION path.

	      This  variable is defined by CMake-generated cmake_install.cmake
	      scripts. It can be used (read-only) by programs or scripts  that
	      source those install scripts. This is used by some CPack genera‐
	      tors (e.g. RPM).

       CMAKE_AUTOMOC_RELAXED_MODE
	      Switch between strict and relaxed automoc mode.

	      By default, automoc behaves exactly as described in the documen‐
	      tation  of  the  AUTOMOC	target property.  When set to TRUE, it
	      accepts more input and tries to find the correct input file  for
	      moc  even	 if it differs from the documented behaviour.  In this
	      mode it e.g. also checks whether a header file is intended to be
	      processed by moc when a "foo.moc" file has been included.

	      Relaxed mode has to be enabled for KDE4 compatibility.

       CMAKE_BACKWARDS_COMPATIBILITY
	      Version of cmake required to build project

	      From  the	 point of view of backwards compatibility, this speci‐
	      fies what version of CMake should be supported. By default  this
	      value  is	 the version number of CMake that you are running. You
	      can set this to an older version of CMake to support  deprecated
	      commands	of  CMake  in  projects that were written to use older
	      versions of CMake. This can be set by the user  or  set  at  the
	      beginning of a CMakeLists file.

       CMAKE_BUILD_TYPE
	      Specifies the build type on single-configuration generators.

	      This  statically	specifies what build type (configuration) will
	      be built in this build tree. Possible values are	empty,	Debug,
	      Release,	RelWithDebInfo	and MinSizeRel.	 This variable is only
	      meaningful to single-configuration generators (such as make  and
	      Ninja) i.e. those which choose a single configuration when CMake
	      runs to generate a build tree as opposed to  multi-configuration
	      generators  which	 offer	selection  of  the build configuration
	      within the generated build environment.  There are many per-con‐
	      fig   properties	 and   variables   (usually   following	 clean
	      SOME_VAR_<CONFIG>	    order      conventions),	  such	    as
	      CMAKE_C_FLAGS_<CONFIG>,	    specified	    as	    uppercase:
	      CMAKE_C_FLAGS_[DEBUG|RELEASE|RELWITHDEBINFO|MINSIZEREL].	   For
	      example,	in  a build tree configured to build type Debug, CMake
	      will see to having CMAKE_C_FLAGS_DEBUG settings get added to the
	      CMAKE_C_FLAGS settings.  See also CMAKE_CONFIGURATION_TYPES.

       CMAKE_COLOR_MAKEFILE
	      Enables color output when using the Makefile generator.

	      When  enabled, the generated Makefiles will produce colored out‐
	      put.  Default is ON.

       CMAKE_CONFIGURATION_TYPES
	      Specifies the available build types on multi-config generators.

	      This specifies what build types (configurations) will be	avail‐
	      able  such as Debug, Release, RelWithDebInfo etc.	 This has rea‐
	      sonable defaults on most platforms, but can be extended to  pro‐
	      vide  other  build types.	 See also CMAKE_BUILD_TYPE for details
	      of managing configuration data, and CMAKE_CFG_INTDIR.

       CMAKE_DEBUG_TARGET_PROPERTIES
	      Enables tracing output for target properties.

	      This variable can be populated with a list of properties to gen‐
	      erate  debug output for when evaluating target properties.  Cur‐
	      rently it can only be used when evaluating the  INCLUDE_DIRECTO‐
	      RIES, COMPILE_DEFINITIONS and COMPILE_OPTIONS target properties.
	      In that case, it outputs a backtrace for each entry in the  tar‐
	      get property.  Default is unset.

       CMAKE_DISABLE_FIND_PACKAGE_<PackageName>
	      Variable for disabling find_package() calls.

	      Every  non-REQUIRED find_package() call in a project can be dis‐
	      abled by setting the variable CMAKE_DISABLE_FIND_PACKAGE_<Packa‐
	      geName>  to TRUE. This can be used to build a project without an
	      optional package, although that package is installed.

	      This switch should be used during the initial CMake run.	Other‐
	      wise  if	the package has already been found in a previous CMake
	      run, the variables which have been  stored  in  the  cache  will
	      still  be	 there.	  In that case it is recommended to remove the
	      cache variables for this package from the cache using the	 cache
	      editor or cmake -U

       CMAKE_ERROR_DEPRECATED
	      Whether to issue deprecation errors for macros and functions.

	      If TRUE, this can be used by macros and functions to issue fatal
	      errors when deprecated macros or functions are used.  This vari‐
	      able is FALSE by default.

       CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
	      Ask  cmake_install.cmake	script	to error out as soon as a file
	      with absolute INSTALL DESTINATION is encountered.

	      The fatal error  is  emitted  before  the	 installation  of  the
	      offending	 file takes place. This variable is used by CMake-gen‐
	      erated cmake_install.cmake scripts. If one sets this variable to
	      ON  while	 running  the  script, it may get fatal error messages
	      from the script.

       CMAKE_FIND_LIBRARY_PREFIXES
	      Prefixes to prepend when looking for libraries.

	      This specifies what prefixes to add to library  names  when  the
	      find_library  command  looks for libraries. On UNIX systems this
	      is typically lib, meaning that  when  trying  to	find  the  foo
	      library it will look for libfoo.

       CMAKE_FIND_LIBRARY_SUFFIXES
	      Suffixes to append when looking for libraries.

	      This  specifies  what  suffixes to add to library names when the
	      find_library command looks for  libraries.  On  Windows  systems
	      this  is	typically  .lib	 and .dll, meaning that when trying to
	      find the foo library it will look for foo.dll etc.

       CMAKE_FIND_PACKAGE_WARN_NO_MODULE
	      Tell find_package to warn if called without an explicit mode.

	      If find_package is called without an explicit mode option	 (MOD‐
	      ULE,  CONFIG  or	NO_MODULE) and no Find<pkg>.cmake module is in
	      CMAKE_MODULE_PATH then CMake implicitly assumes that the	caller
	      intends to search for a package configuration file.  If no pack‐
	      age configuration file is found then the wording of the  failure
	      message  must  account  for  both	 the  case that the package is
	      really missing and the case that	the  project  has  a  bug  and
	      failed  to  provide  the	intended  Find module.	If instead the
	      caller specifies an explicit mode option then the	 failure  mes‐
	      sage can be more specific.

	      Set CMAKE_FIND_PACKAGE_WARN_NO_MODULE to TRUE to tell find_pack‐
	      age to warn when it implicitly assumes Config mode.  This	 helps
	      developers  enforce  use	of  an	explicit  mode in all calls to
	      find_package within a project.

       CMAKE_IGNORE_PATH
	      Path to be ignored by FIND_XXX() commands.

	      Specifies directories to be ignored by  searches	in  FIND_XXX()
	      commands.	  This	is useful in cross-compiled environments where
	      some system directories contain incompatible but possibly	 link‐
	      able  libraries. For example, on cross-compiled cluster environ‐
	      ments, this allows  a  user  to  ignore  directories  containing
	      libraries	 meant	for  the  front-end  machine that modules like
	      FindX11 (and others) would normally search.  By default this  is
	      empty;  it  is  intended	to  be	set by the project.  Note that
	      CMAKE_IGNORE_PATH takes a list of directory names, NOT a list of
	      prefixes.	 If  you  want	to  ignore  paths under prefixes (bin,
	      include, lib, etc.), you'll need	to  specify  them  explicitly.
	      See	also	   CMAKE_PREFIX_PATH,	   CMAKE_LIBRARY_PATH,
	      CMAKE_INCLUDE_PATH, CMAKE_PROGRAM_PATH.

       CMAKE_INCLUDE_PATH
	      Path used for searching by FIND_FILE() and FIND_PATH().

	      Specifies a path which will be  used  both  by  FIND_FILE()  and
	      FIND_PATH().  Both  commands  will  check	 each of the contained
	      directories for the existence of the  file  which	 is  currently
	      searched.	 By  default  it is empty, it is intended to be set by
	      the  project.  See  also	CMAKE_SYSTEM_INCLUDE_PATH,  CMAKE_PRE‐
	      FIX_PATH.

       CMAKE_INSTALL_DEFAULT_COMPONENT_NAME
	      Default component used in install() commands.

	      If  an install() command is used without the COMPONENT argument,
	      these files will be grouped into a default component.  The  name
	      of  this default install component will be taken from this vari‐
	      able.  It defaults to "Unspecified".

       CMAKE_INSTALL_PREFIX
	      Install directory used by install.

	      If "make install" is invoked or INSTALL is built, this directory
	      is   prepended  onto  all	 install  directories.	This  variable
	      defaults to /usr/local on UNIX and c:/Program Files on Windows.

	      On UNIX one can use the DESTDIR mechanism in order  to  relocate
	      the whole installation.  DESTDIR means DESTination DIRectory. It
	      is commonly used by makefile users in order to install  software
	      at non-default location.	It is usually invoked like this:

	       make DESTDIR=/home/john install

	      which will install the concerned software using the installation
	      prefix, e.g. "/usr/local" prepended with the DESTDIR value which
	      finally gives "/home/john/usr/local".

	      WARNING: DESTDIR may not be used on Windows because installation
	      prefix usually contains  a  drive	 letter	 like  in  "C:/Program
	      Files" which cannot be prepended with some other prefix.

	      The  installation	 prefix	 is  also  added  to CMAKE_SYSTEM_PRE‐
	      FIX_PATH	so  that  find_package,	 find_program,	 find_library,
	      find_path,  and find_file will search the prefix for other soft‐
	      ware.

       CMAKE_LIBRARY_PATH
	      Path used for searching by FIND_LIBRARY().

	      Specifies	 a  path  which	 will  be  used	  by   FIND_LIBRARY().
	      FIND_LIBRARY()  will check each of the contained directories for
	      the existence of the library which  is  currently	 searched.  By
	      default  it  is  empty, it is intended to be set by the project.
	      See also CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_PREFIX_PATH.

       CMAKE_MFC_FLAG
	      Tell cmake to use MFC for an executable or dll.

	      This can be set in a CMakeLists.txt file and will enable MFC  in
	      the  application.	  It  should  be  set  to 1 for the static MFC
	      library, and 2 for the shared MFC library.  This is used in Vis‐
	      ual  Studio  6 and 7 project files.   The CMakeSetup dialog used
	      MFC and the CMakeLists.txt looks like this:

		add_definitions(-D_AFXDLL)
		set(CMAKE_MFC_FLAG 2)
		add_executable(CMakeSetup WIN32 ${SRCS})

       CMAKE_MODULE_PATH
	      List of directories to search for CMake modules.

	      Commands like include() and find_package() search for  files  in
	      directories  listed by this variable before checking the default
	      modules that come with CMake.

       CMAKE_NOT_USING_CONFIG_FLAGS
	      Skip _BUILD_TYPE flags if true.

	      This is an internal flag used by the generators in CMake to tell
	      CMake to skip the _BUILD_TYPE flags.

       CMAKE_POLICY_DEFAULT_CMP<NNNN>
	      Default  for  CMake  Policy  CMP<NNNN> when it is otherwise left
	      unset.

	      Commands cmake_minimum_required(VERSION)	and  cmake_policy(VER‐
	      SION)  by default leave policies introduced after the given ver‐
	      sion unset.  Set CMAKE_POLICY_DEFAULT_CMP<NNNN> to OLD or NEW to
	      specify  the  default  for policy CMP<NNNN>, where <NNNN> is the
	      policy number.

	      This variable should not be set by a project in CMake code;  use
	      cmake_policy(SET)	 instead.   Users  running  CMake may set this
	      variable	   in	   the	    cache      (e.g.	  -DCMAKE_POL‐
	      ICY_DEFAULT_CMP<NNNN>=<OLD|NEW>)	to  set a policy not otherwise
	      set by the project.  Set to OLD to quiet a policy warning	 while
	      using  old  behavior  or to NEW to try building the project with
	      new behavior.

       CMAKE_PREFIX_PATH
	      Path used for searching by FIND_XXX(), with appropriate suffixes
	      added.

	      Specifies	 a path which will be used by the FIND_XXX() commands.
	      It contains the  "base"  directories,  the  FIND_XXX()  commands
	      append  appropriate  subdirectories  to the base directories. So
	      FIND_PROGRAM() adds /bin to each of the directories in the path,
	      FIND_LIBRARY()  appends  /lib  to	 each  of the directories, and
	      FIND_PATH() and FIND_FILE() append /include . By default	it  is
	      empty,  it  is  intended	to  be	set  by	 the project. See also
	      CMAKE_SYSTEM_PREFIX_PATH,			   CMAKE_INCLUDE_PATH,
	      CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.

       CMAKE_PROGRAM_PATH
	      Path used for searching by FIND_PROGRAM().

	      Specifies a path which will be used by FIND_PROGRAM(). FIND_PRO‐
	      GRAM() will check each of	 the  contained	 directories  for  the
	      existence of the program which is currently searched. By default
	      it is empty, it is intended to be set by the project.  See  also
	      CMAKE_SYSTEM_PROGRAM_PATH,  CMAKE_PREFIX_PATH.

       CMAKE_SKIP_INSTALL_ALL_DEPENDENCY
	      Don't make the install target depend on the all target.

	      By  default,  the	 "install" target depends on the "all" target.
	      This has the effect, that when  "make  install"  is  invoked  or
	      INSTALL  is  built,  first  the  "all" target is built, then the
	      installation starts.   If	 CMAKE_SKIP_INSTALL_ALL_DEPENDENCY  is
	      set to TRUE, this dependency is not created, so the installation
	      process will start immediately,  independent  from  whether  the
	      project has been completely built or not.

       CMAKE_SYSTEM_IGNORE_PATH
	      Path to be ignored by FIND_XXX() commands.

	      Specifies	 directories  to  be ignored by searches in FIND_XXX()
	      commands.	 This is useful in cross-compiled  environments	 where
	      some  system directories contain incompatible but possibly link‐
	      able libraries. For example, on cross-compiled cluster  environ‐
	      ments,  this  allows  a  user  to	 ignore directories containing
	      libraries meant for the  front-end  machine  that	 modules  like
	      FindX11  (and  others)  would  normally search.  By default this
	      contains a list of directories containing incompatible  binaries
	      for   the	  host	system.	  See  also  CMAKE_SYSTEM_PREFIX_PATH,
	      CMAKE_SYSTEM_LIBRARY_PATH,    CMAKE_SYSTEM_INCLUDE_PATH,	   and
	      CMAKE_SYSTEM_PROGRAM_PATH.

       CMAKE_SYSTEM_INCLUDE_PATH
	      Path used for searching by FIND_FILE() and FIND_PATH().

	      Specifies	 a  path  which	 will  be used both by FIND_FILE() and
	      FIND_PATH(). Both commands will  check  each  of	the  contained
	      directories  for	the  existence	of the file which is currently
	      searched. By default it contains the  standard  directories  for
	      the  current  system.  It	 is NOT intended to be modified by the
	      project, use CMAKE_INCLUDE_PATH for this.	 See  also  CMAKE_SYS‐
	      TEM_PREFIX_PATH.

       CMAKE_SYSTEM_LIBRARY_PATH
	      Path used for searching by FIND_LIBRARY().

	      Specifies	  a   path  which  will	 be  used  by  FIND_LIBRARY().
	      FIND_LIBRARY() will check each of the contained directories  for
	      the  existence  of  the  library which is currently searched. By
	      default it contains the standard	directories  for  the  current
	      system.  It  is  NOT intended to be modified by the project, use
	      CMAKE_LIBRARY_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

       CMAKE_SYSTEM_PREFIX_PATH
	      Path used for searching by FIND_XXX(), with appropriate suffixes
	      added.

	      Specifies	 a path which will be used by the FIND_XXX() commands.
	      It contains the  "base"  directories,  the  FIND_XXX()  commands
	      append  appropriate  subdirectories  to the base directories. So
	      FIND_PROGRAM() adds /bin to each of the directories in the path,
	      FIND_LIBRARY()  appends  /lib  to	 each  of the directories, and
	      FIND_PATH() and FIND_FILE() append /include .  By	 default  this
	      contains the standard directories for the current system and the
	      CMAKE_INSTALL_PREFIX.  It is NOT intended to be modified by  the
	      project,	use  CMAKE_PREFIX_PATH	for  this. See also CMAKE_SYS‐
	      TEM_INCLUDE_PATH,	 CMAKE_SYSTEM_LIBRARY_PATH,  CMAKE_SYSTEM_PRO‐
	      GRAM_PATH, and CMAKE_SYSTEM_IGNORE_PATH.

       CMAKE_SYSTEM_PROGRAM_PATH
	      Path used for searching by FIND_PROGRAM().

	      Specifies a path which will be used by FIND_PROGRAM(). FIND_PRO‐
	      GRAM() will check each of	 the  contained	 directories  for  the
	      existence of the program which is currently searched. By default
	      it contains the standard directories for the current system.  It
	      is  NOT  intended	 to be modified by the project, use CMAKE_PRO‐
	      GRAM_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

       CMAKE_USER_MAKE_RULES_OVERRIDE
	      Specify a CMake file that overrides platform information.

	      CMake loads the specified file while enabling support  for  each
	      language	from  either  the  project() or enable_language() com‐
	      mands.  It is loaded after CMake's builtin compiler and platform
	      information  modules have been loaded but before the information
	      is used.	The file may set  platform  information	 variables  to
	      override CMake's defaults.

	      This  feature is intended for use only in overriding information
	      variables that must be set before CMake builds  its  first  test
	      project  to  check  that	the compiler for a language works.  It
	      should not be used to  load  a  file  in	cases  that  a	normal
	      include()	 will work.  Use it only as a last resort for behavior
	      that cannot be achieved any other way.  For example, one may set
	      CMAKE_C_FLAGS_INIT  to change the default value used to initial‐
	      ize CMAKE_C_FLAGS before it is cached.  The override file should
	      NOT  be  used  to set anything that could be set after languages
	      are enabled, such as variables like  CMAKE_RUNTIME_OUTPUT_DIREC‐
	      TORY  that affect the placement of binaries.  Information set in
	      the file will be used for try_compile and try_run builds too.

       CMAKE_WARN_DEPRECATED
	      Whether to issue deprecation warnings for macros and functions.

	      If TRUE, this can be used by macros and functions to issue  dep‐
	      recation warnings.  This variable is FALSE by default.

       CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
	      Ask  cmake_install.cmake	script	to  warn each time a file with
	      absolute INSTALL DESTINATION is encountered.

	      This variable is	used  by  CMake-generated  cmake_install.cmake
	      scripts.	If  one	 sets  this  variable  to ON while running the
	      script, it may get warning messages from the script.

VARIABLES THAT DESCRIBE THE SYSTEM
       APPLE  True if running on Mac OS X.

	      Set to true on Mac OS X.

       BORLAND
	      True if the Borland compiler is being used.

	      This is set to true if the Borland compiler is being used.

       CMAKE_CL_64
	      Using the 64 bit compiler from Microsoft

	      Set to true when using the 64 bit cl compiler from Microsoft.

       CMAKE_COMPILER_2005
	      Using the Visual Studio 2005 compiler from Microsoft

	      Set to true when using the Visual Studio 2005 compiler from  Mi‐
	      crosoft.

       CMAKE_HOST_APPLE
	      True for Apple OS X operating systems.

	      Set to true when the host system is Apple OS X.

       CMAKE_HOST_SYSTEM
	      Name of system cmake is being run on.

	      The  same as CMAKE_SYSTEM but for the host system instead of the
	      target system when cross compiling.

       CMAKE_HOST_SYSTEM_NAME
	      Name of the OS CMake is running on.

	      The same as CMAKE_SYSTEM_NAME but for the host system instead of
	      the target system when cross compiling.

       CMAKE_HOST_SYSTEM_PROCESSOR
	      The name of the CPU CMake is running on.

	      The  same	 as  CMAKE_SYSTEM_PROCESSOR  but  for  the host system
	      instead of the target system when cross compiling.

       CMAKE_HOST_SYSTEM_VERSION
	      OS version CMake is running on.

	      The same as CMAKE_SYSTEM_VERSION but for the host system instead
	      of the target system when cross compiling.

       CMAKE_HOST_UNIX
	      True for UNIX and UNIX like operating systems.

	      Set  to  true  when  the	host system is UNIX or UNIX like (i.e.
	      APPLE and CYGWIN).

       CMAKE_HOST_WIN32
	      True on windows systems, including win64.

	      Set to true when the host system is Windows and on Cygwin.

       CMAKE_LIBRARY_ARCHITECTURE
	      Target architecture library directory name, if detected.

	      This  is	the  value  of	CMAKE_<lang>_LIBRARY_ARCHITECTURE   as
	      detected for one of the enabled languages.

       CMAKE_LIBRARY_ARCHITECTURE_REGEX
	      Regex  matching  possible	 target architecture library directory
	      names.

	      This is used to  detect  CMAKE_<lang>_LIBRARY_ARCHITECTURE  from
	      the implicit linker search path by matching the <arch> name.

       CMAKE_OBJECT_PATH_MAX
	      Maximum  object  file  full-path	length allowed by native build
	      tools.

	      CMake computes for every source file an object file name that is
	      unique  to the source file and deterministic with respect to the
	      full path to the source file.  This allows multiple source files
	      in  a  target  to	 share	the same name if they lie in different
	      directories without rebuilding when one  is  added  or  removed.
	      However, it can produce long full paths in a few cases, so CMake
	      shortens the path using a hashing scheme when the full  path  to
	      an  object file exceeds a limit.	CMake has a built-in limit for
	      each platform that is sufficient	for  common  tools,  but  some
	      native  tools  may have a lower limit.  This variable may be set
	      to specify the limit explicitly.	The value must be  an  integer
	      no less than 128.

       CMAKE_SYSTEM
	      Name of system cmake is compiling for.

	      This   variable	is  the	 composite  of	CMAKE_SYSTEM_NAME  and
	      CMAKE_SYSTEM_VERSION,	  like	      this	  ${CMAKE_SYS‐
	      TEM_NAME}-${CMAKE_SYSTEM_VERSION}.   If  CMAKE_SYSTEM_VERSION is
	      not set, then CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.

       CMAKE_SYSTEM_NAME
	      Name of the OS CMake is building for.

	      This is the name of the operating system on which CMake is  tar‐

	      or languages.

       CMAKE_<LANG>_COMPILER_LOADED
	      Defined to true if the language is enabled.

	      When  language  <LANG>  is  enabled  by project() or enable_lan‐
	      guage() this variable is defined to 1.

       CMAKE_<LANG>_COMPILER_VERSION
	      Compiler version string.

	      Compiler version in major[.minor[.patch[.tweak]]] format.	  This
	      variable	is  not	 guaranteed to be defined for all compilers or
	      languages.

       CMAKE_<LANG>_COMPILE_OBJECT
	      Rule variable to compile a single object file.

	      This is a rule variable that tells CMake how to compile a single
	      object file for the language <LANG>.

       CMAKE_<LANG>_CREATE_SHARED_LIBRARY
	      Rule variable to create a shared library.

	      This  is a rule variable that tells CMake how to create a shared
	      library for the language <LANG>.

       CMAKE_<LANG>_CREATE_SHARED_MODULE

	      <LANG> flags used regardless of the value of CMAKE_BUILD_TYPE.

       CMAKE_<LANG>_FLAGS_DEBUG
	      Flags for Debug build type or configuration.

	      <LANG> flags used when CMAKE_BUILD_TYPE is Debug.

       CMAKE_<LANG>_FLAGS_MINSIZEREL
	      Flags for MinSizeRel build type or configuration.

       CMAKE_<LANG>_IGNORE_EXTENSIONS
	      File extensions that should be ignored by the build.

	      This is a list of file extensions that may be part of a  project
	      for a given language but are not compiled.

       CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES
	      Directories  implicitly  searched	 by  the  compiler  for header
	      files.

	      CMake does not explicitly specify these directories on  compiler
	      command lines for language <LANG>.  This prevents system include
	      directories from being treated as user  include  directories  on
	      some compilers.

       CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
	      Implicit linker search path detected for language <LANG>.

	      Compilers typically pass directories containing language runtime
	      libraries and default library search paths when  they  invoke  a
	      linker.	These paths are implicit linker search directories for
	      the compiler's  language.	  CMake	 automatically	detects	 these
	      directories  for	each  language and reports the results in this
	      variable.

	      When a library in one of these directories is given by full path
	      to target_link_libraries() CMake will generate the -l<name> form
	      on link lines to ensure the linker searches its implicit	direc‐
	      tories for the library.  Note that some toolchains read implicit
	      directories from an environment variable such as LIBRARY_PATH so
	      keep its value consistent when operating in a given build tree.

       CMAKE_<LANG>_IMPLICIT_LINK_FRAMEWORK_DIRECTORIES
	      Implicit	linker	framework  search  path	 detected for language
	      <LANG>.

	      These paths are implicit linker framework search directories for
	      the  compiler's  language.   CMake  automatically	 detects these
	      directories for each language and reports the  results  in  this
	      variable.

       CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
	      Implicit link libraries and flags detected for language <LANG>.

	      Compilers	 typically  pass  language  runtime  library names and
	      other flags when they invoke a linker.  These flags are implicit
	      link  options  for the compiler's language.  CMake automatically
	      detects these libraries and flags for each language and  reports
	      the results in this variable.

       CMAKE_<LANG>_LIBRARY_ARCHITECTURE
	      Target architecture library directory name detected for <lang>.

	      If the <lang> compiler passes to the linker an architecture-spe‐
	      cific  system   library	search	 directory   such   as	 <pre‐
	      fix>/lib/<arch>  this  variable  contains	 the <arch> name if/as
	      detected by CMake.

       CMAKE_<LANG>_LINKER_PREFERENCE
	      Preference value for linker language selection.

	      The "linker language" for executable, shared library, and module
	      targets  is  the language whose compiler will invoke the linker.
	      The LINKER_LANGUAGE target property sets	the  language  explic‐
	      itly.  Otherwise, the linker language is that whose linker pref‐
	      erence value is highest among languages compiled and linked into
	      the  target.  See also the CMAKE_<LANG>_LINKER_PREFERENCE_PROPA‐
	      GATES variable.

       CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES
	      True if CMAKE_<LANG>_LINKER_PREFERENCE  propagates  across  tar‐
	      gets.

	      This  is used when CMake selects a linker language for a target.
	      Languages compiled directly into the target are  always  consid‐
	      ered.   A	 language compiled into static libraries linked by the
	      target is considered if this variable is true.

       CMAKE_<LANG>_LINK_EXECUTABLE
	      Rule variable to link an executable.

	      Rule variable to link an executable for the given language.

       CMAKE_<LANG>_OUTPUT_EXTENSION
	      Extension for the output of a compile for a single file.

	      This is the extension for an object file for the	given  <LANG>.
	      For example .obj for C on Windows.

       CMAKE_<LANG>_PLATFORM_ID
	      An internal variable subject to change.

	      This  is	used  in  determining  the  platform and is subject to
	      change.

       CMAKE_<LANG>_SIZEOF_DATA_PTR
	      Size of pointer-to-data types for language <LANG>.

	      This holds the size (in bytes) of pointer-to-data types  in  the
	      target  platform	ABI.   It  is  defined for languages C and CXX
	      (C++).

       CMAKE_<LANG>_SOURCE_FILE_EXTENSIONS
	      Extensions of source files for the given language.

	      This is the list of extensions for  a  given  language's	source
	      files.

       CMAKE_COMPILER_IS_GNU<LANG>
	      True if the compiler is GNU.

	      If the selected <LANG> compiler is the GNU compiler then this is
	      TRUE, if not it is FALSE.	 Unlike the other  per-language	 vari‐
	      ables,  this  uses  the  GNU  syntax  for	 identifying languages
	      instead of the CMake syntax. Recognized  values  of  the	<LANG>
	      suffix are:

		CC = C compiler
		CXX = C++ compiler
		G77 = Fortran compiler

       CMAKE_Fortran_MODDIR_DEFAULT
	      Fortran default module output directory.

	      Most  Fortran  compilers write .mod files to the current working
	      directory.  For those that do not, this is set to "."  and  used
	      when the Fortran_MODULE_DIRECTORY target property is not set.

       CMAKE_Fortran_MODDIR_FLAG
	      Fortran flag for module output directory.

	      This  stores  the	 flag  needed  to  pass	 the value of the For‐
	      tran_MODULE_DIRECTORY target property to the compiler.

       CMAKE_Fortran_MODOUT_FLAG
	      Fortran flag to enable module output.

	      Most Fortran compilers write .mod files  out  by	default.   For
	      others, this stores the flag needed to enable module output.

       CMAKE_INTERNAL_PLATFORM_ABI
	      An internal variable subject to change.

	      This  is	used in determining the compiler ABI and is subject to
	      change.

       CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG>
	      Specify a CMake file that	 overrides  platform  information  for
	      <LANG>.

	      This	 is	 a	language-specific      version	    of
	      CMAKE_USER_MAKE_RULES_OVERRIDE loaded only  when	enabling  lan‐
	      guage <LANG>.

VARIABLES THAT CONTROL THE BUILD
       CMAKE_<CONFIG>_POSTFIX
	      Default filename postfix for libraries under configuration <CON‐
	      FIG>.

	      tion.

       CMAKE_AUTOMOC_MOC_OPTIONS
	      Additional options for moc when using automoc  (see  CMAKE_AUTO‐
	      MOC).

	      This  variable  is  used	to  initialize the AUTOMOC_MOC_OPTIONS
	      property on all the targets.  See that target property for addi‐
	      tional information.

       CMAKE_BUILD_WITH_INSTALL_RPATH
	      Use the install path for the RPATH

	      Normally	CMake  uses the build tree for the RPATH when building
	      executables etc on systems that use RPATH. When the software  is
	      installed	 the executables etc are relinked by CMake to have the
	      install RPATH. If this variable is set to true then the software
	      is always built with the install path for the RPATH and does not
	      need to be relinked when installed.

       CMAKE_DEBUG_POSTFIX
	      See variable CMAKE_<CONFIG>_POSTFIX.

	      This variable is a special case of the more-general  CMAKE_<CON‐
	      FIG>_POSTFIX variable for the DEBUG configuration.

       CMAKE_EXE_LINKER_FLAGS
	      Linker flags to be used to create executables.

	      These  flags  will  be  used by the linker when creating an exe‐
	      cutable.

       CMAKE_EXE_LINKER_FLAGS_<CONFIG>
	      Flags to be used when linking an executable.

	      Same as CMAKE_C_FLAGS_* but used by  the	linker	when  creating
	      executables.

       CMAKE_Fortran_FORMAT
	      Set to FIXED or FREE to indicate the Fortran source layout.

	      This  variable is used to initialize the Fortran_FORMAT property
	      on all the targets.  See that  target  property  for  additional
	      information.

       CMAKE_Fortran_MODULE_DIRECTORY
	      Fortran module output directory.

	      This variable is used to initialize the Fortran_MODULE_DIRECTORY
	      property on all the targets.  See that target property for addi‐
	      tional information.

       CMAKE_GNUtoMS
	      Convert GNU import libraries (.dll.a) to MS format (.lib).

	      This variable is used to initialize the GNUtoMS property on tar‐
	      gets when they are created.  See that target property for	 addi‐
	      tional information.

       CMAKE_INCLUDE_CURRENT_DIR
	      Automatically  add  the current source- and build directories to
	      the include path.

	      If this variable is enabled, CMake automatically	adds  in  each
	      directory	    ${CMAKE_CURRENT_SOURCE_DIR}	   and	  ${CMAKE_CUR‐
	      RENT_BINARY_DIR} to the include path for this  directory.	 These
	      additional  include  directories do not propagate down to subdi‐
	      rectories. This is useful mainly for out-of-source builds, where
	      files  generated	into  the  build  tree	are  included by files
	      located in the source tree.

	      By default CMAKE_INCLUDE_CURRENT_DIR is OFF.

       CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE
	      Automatically add the current source- and build  directories  to
	      the INTERFACE_INCLUDE_DIRECTORIES.

	      If  this	variable is enabled, CMake automatically adds for each
	      shared library target, static library target, module target  and
	      executable  target, ${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CUR‐
	      RENT_BINARY_DIR} to the INTERFACE_INCLUDE_DIRECTORIES.By default
	      CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE is OFF.

       CMAKE_INSTALL_NAME_DIR
	      Mac OS X directory name for installed targets.

	      CMAKE_INSTALL_NAME_DIR	 is    used    to    initialize	   the
	      INSTALL_NAME_DIR property on all targets. See that target	 prop‐
	      erty for more information.

       CMAKE_INSTALL_RPATH
	      The rpath to use for installed targets.

	      A	 semicolon-separated  list  specifying	the  rpath  to	use in
	      installed targets (for platforms that support it).  This is used
	      to initialize the target property INSTALL_RPATH for all targets.

       CMAKE_INSTALL_RPATH_USE_LINK_PATH
	      Add paths to linker search and installed rpath.

	      CMAKE_INSTALL_RPATH_USE_LINK_PATH	 is  a	boolean that if set to
	      true will append directories in the linker search path and  out‐
	      side the project to the INSTALL_RPATH.  This is used to initial‐
	      ize the target property INSTALL_RPATH_USE_LINK_PATH for all tar‐
	      gets.

       CMAKE_LIBRARY_OUTPUT_DIRECTORY
	      Where to put all the LIBRARY targets when built.

	      This variable is used to initialize the LIBRARY_OUTPUT_DIRECTORY
	      property on all the targets.  See that target property for addi‐
	      tional information.

       CMAKE_LIBRARY_PATH_FLAG
	      The flag to be used to add a library search path to a compiler.

	      piler.  On most compilers this is "-L".

       CMAKE_LINK_DEF_FILE_FLAG
	      Linker flag to be used to specify a .def file for dll creation.

	      The flag will be used to add a .def file when creating a dll  on
	      Windows; this is only defined on Windows.

       CMAKE_LINK_DEPENDS_NO_SHARED
	      Whether to skip link dependencies on shared library files.

	      This variable initializes the LINK_DEPENDS_NO_SHARED property on

	      Flag  to	be  used  to link a library specified by a path to its
	      file.

	      The flag will be used before a library file path is given to the
	      linker.  This is needed only on very few platforms.

       CMAKE_LINK_LIBRARY_FLAG
	      Flag to be used to link a library into an executable.

	      The  flag	 will  be used to specify a library to link to an exe‐
	      cutable.	On most compilers this is "-l".

       CMAKE_MACOSX_BUNDLE
	      Default value for MACOSX_BUNDLE of targets.

	      This variable is used to initialize the  MACOSX_BUNDLE  property
	      on  all  the  targets.   See that target property for additional
	      information.

       CMAKE_MODULE_LINKER_FLAGS
	      Linker flags to be used to create modules.

	      These flags will be used by the linker when creating a module.

       CMAKE_MODULE_LINKER_FLAGS_<CONFIG>
	      Flags to be used when linking a module.

	      Same as CMAKE_C_FLAGS_* but used by  the	linker	when  creating
	      modules.

       CMAKE_NO_BUILTIN_CHRPATH
	      Do not use the builtin ELF editor to fix RPATHs on installation.

	      When an ELF binary needs to have a different RPATH after instal‐
	      lation than it does in the build tree, CMake uses a builtin edi‐
	      tor to change the RPATH in the installed copy.  If this variable
	      is set to true then CMake will relink the binary before  instal‐
	      lation instead of using its builtin editor.

       CMAKE_PDB_OUTPUT_DIRECTORY
	      Where to put all the MS debug symbol files from linker.

	      This  variable  is  used	to initialize the PDB_OUTPUT_DIRECTORY
	      property on all the targets.  See that target property for addi‐
	      tional information.

       CMAKE_POSITION_INDEPENDENT_CODE
	      Default value for POSITION_INDEPENDENT_CODE of targets.

	      This  variable  is  used	to  initialize	the  POSITION_INDEPEN‐
	      DENT_CODE property on all the targets.  See that target property
	      for additional information.

       CMAKE_RUNTIME_OUTPUT_DIRECTORY
	      Where to put all the RUNTIME targets when built.

	      This variable is used to initialize the RUNTIME_OUTPUT_DIRECTORY
	      property on all the targets.  See that target property for addi‐
	      tional information.

       CMAKE_SHARED_LINKER_FLAGS
	      Linker flags to be used to create shared libraries.

	      These  flags  will  be used by the linker when creating a shared
	      library.

       CMAKE_SHARED_LINKER_FLAGS_<CONFIG>
	      Flags to be used when linking a shared library.

	      Same as CMAKE_C_FLAGS_* but used by  the	linker	when  creating
	      shared libraries.

       CMAKE_SKIP_BUILD_RPATH
	      Do not include RPATHs in the build tree.

	      Normally	CMake  uses the build tree for the RPATH when building
	      executables etc on systems that use RPATH. When the software  is
	      installed	 the executables etc are relinked by CMake to have the
	      install RPATH. If this variable is set to true then the software
	      is always built with no RPATH.

       CMAKE_SKIP_INSTALL_RPATH
	      Do not include RPATHs in the install tree.

	      Normally	CMake  uses the build tree for the RPATH when building
	      executables etc on systems that use RPATH. When the software  is
	      installed	 the executables etc are relinked by CMake to have the
	      install RPATH. If this variable is set to true then the software
	      is always installed without RPATH, even if RPATH is enabled when
	      building.	 This can be useful for example to allow running tests
	      from the build directory with RPATH enabled before the installa‐
	      tion step.  To omit RPATH in both the build and  install	steps,
	      use CMAKE_SKIP_RPATH instead.

       CMAKE_STATIC_LINKER_FLAGS
	      Linker flags to be used to create static libraries.

	      These  flags  will  be used by the linker when creating a static
	      library.

       CMAKE_STATIC_LINKER_FLAGS_<CONFIG>
	      Flags to be used when linking a static library.

	      Same as CMAKE_C_FLAGS_* but used by  the	linker	when  creating
	      static libraries.

       CMAKE_TRY_COMPILE_CONFIGURATION
	      Build configuration used for try_compile and try_run projects.

	      Projects	built  by  try_compile	and  try_run  are  built  syn‐
	      chronously during the CMake  configuration  step.	  Therefore  a
	      specific	build  configuration must be chosen even if the gener‐
	      ated build system supports multiple configurations.

       CMAKE_USE_RELATIVE_PATHS
	      Use relative paths (May not work!).

	      If this is set to TRUE,  then  CMake  will  use  relative	 paths
	      between  the  source and binary tree.  This option does not work
	      for more complicated projects, and relative paths are used  when
	      possible.	  In  general, it is not possible to move CMake gener‐
	      ated makefiles to a different location regardless of  the	 value
	      of this variable.

       CMAKE_VISIBILITY_INLINES_HIDDEN
	      Default value for VISIBILITY_INLINES_HIDDEN of targets.

	      This  variable is used to initialize the VISIBILITY_INLINES_HID‐
	      DEN property on all the targets.	See that target	 property  for
	      additional information.

       CMAKE_WIN32_EXECUTABLE
	      Default value for WIN32_EXECUTABLE of targets.

	      This  variable  is used to initialize the WIN32_EXECUTABLE prop‐
	      erty on all the targets.	See that  target  property  for	 addi‐
	      tional information.

       EXECUTABLE_OUTPUT_PATH
	      Old executable location variable.

	      The  target  property  RUNTIME_OUTPUT_DIRECTORY  supercedes this
	      variable for a target if it is set.  Executable targets are oth‐
	      erwise placed in this directory.

       LIBRARY_OUTPUT_PATH
	      Old library location variable.

	      The  target  properties  ARCHIVE_OUTPUT_DIRECTORY,  LIBRARY_OUT‐
	      PUT_DIRECTORY, and RUNTIME_OUTPUT_DIRECTORY supercede this vari‐
	      able  for	 a target if they are set.  Library targets are other‐
	      wise placed in this directory.

VARIABLES THAT PROVIDE INFORMATION
       variables defined by cmake, that give information  about	 the  project,
       and cmake

       CMAKE_AR
	      Name of archiving tool for static libraries.

	      This  specifies  the name of the program that creates archive or
	      static libraries.

       CMAKE_ARGC
	      Number of command line arguments passed to CMake in script mode.

	      When run in -P script mode, CMake sets this variable to the num‐
	      ber of command line arguments. See also CMAKE_ARGV0, 1, 2 ...

       CMAKE_ARGV0
	      Command line argument passed to CMake in script mode.

	      When  run	 in  -P	 script	 mode, CMake sets this variable to the
	      first command line argument.  It	then  also  sets  CMAKE_ARGV1,
	      CMAKE_ARGV2,  ...	 and  so  on, up to the number of command line
	      arguments given. See also CMAKE_ARGC.

       CMAKE_BINARY_DIR
	      The path to the top level of the build tree.

	      This is the full path to the top	level  of  the	current	 CMake
	      build  tree.  For	 an in-source build, this would be the same as
	      CMAKE_SOURCE_DIR.

       CMAKE_BUILD_TOOL
	      Tool used for the actual build process.

	      This variable is set to the program that will be needed to build
	      the output of CMake.   If the generator selected was Visual Stu‐
	      dio 6, the CMAKE_BUILD_TOOL will be set to msdev, for Unix Make‐
	      files  it	 will be set to make or gmake, and for Visual Studio 7
	      it set to devenv.	 For NMake Makefiles the value is nmake.  This
	      can be useful for adding special flags and commands based on the
	      final build environment.

       CMAKE_CACHEFILE_DIR
	      The directory with the CMakeCache.txt file.

	      This is the full path to	the  directory	that  has  the	CMake‐
	      Cache.txt file in it.  This is the same as CMAKE_BINARY_DIR.

       CMAKE_CACHE_MAJOR_VERSION
	      Major version of CMake used to create the CMakeCache.txt file

	      This  stores  the	 major	version of CMake used to write a CMake
	      cache file. It is only different when  a	different  version  of
	      CMake is run on a previously created cache file.

       CMAKE_CACHE_MINOR_VERSION
	      Minor version of CMake used to create the CMakeCache.txt file

	      This  stores  the	 minor	version of CMake used to write a CMake
	      cache file. It is only different when  a	different  version  of
	      CMake is run on a previously created cache file.

       CMAKE_CACHE_PATCH_VERSION
	      Patch version of CMake used to create the CMakeCache.txt file

	      This  stores  the	 patch	version of CMake used to write a CMake
	      cache file. It is only different when  a	different  version  of
	      CMake is run on a previously created cache file.

       CMAKE_CFG_INTDIR
	      Build-time reference to per-configuration output subdirectory.

	      For  native  build systems supporting multiple configurations in
	      the build tree (such as Visual Studio and Xcode), the value is a
	      reference	 to  a	build-time variable specifying the name of the
	      per-configuration output subdirectory.  On  Makefile  generators
	      this evaluates to "." because there is only one configuration in
	      a build tree.  Example values:

		$(IntDir)	 = Visual Studio 6
		$(OutDir)	 = Visual Studio 7, 8, 9
		$(Configuration) = Visual Studio 10
		$(CONFIGURATION) = Xcode
		.		 = Make-based tools

	      Since these values are evaluated by  the	native	build  system,
	      this  variable  is  suitable  only for use in command lines that
	      will be evaluated at build time.	Example of intended usage:

		add_executable(mytool mytool.c)
		add_custom_command(
		  OUTPUT out.txt
		  COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool
			  ${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt
		  DEPENDS mytool in.txt
		  )
		add_custom_target(drive ALL DEPENDS out.txt)

	      Note that CMAKE_CFG_INTDIR is no longer necessary for this  pur‐
	      pose but has been left for compatibility with existing projects.
	      Instead add_custom_command() recognizes executable target	 names
	      in      its      COMMAND	    option,	 so	 "${CMAKE_CUR‐
	      RENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool" can be replaced  by
	      just "mytool".

	      This  variable  is read-only.  Setting it is undefined behavior.
	      In multi-configuration build systems the value of this  variable
	      is  passed as the value of preprocessor symbol "CMAKE_INTDIR" to
	      the compilation of all source files.

       CMAKE_COMMAND
	      The full path to the cmake executable.

	      This is the full path to the CMake  executable  cmake  which  is
	      useful from custom commands that want to use the cmake -E option
	      for portable system commands.  (e.g. /usr/local/bin/cmake

       CMAKE_CROSSCOMPILING
	      Is CMake currently cross compiling.

	      This variable will be set to true by CMake  if  CMake  is	 cross
	      compiling.  Specifically if the build platform is different from
	      the target platform.

       CMAKE_CTEST_COMMAND
	      Full path to ctest command installed with cmake.

	      This is the full path to the CTest  executable  ctest  which  is
	      useful from custom commands that want to use the cmake -E option
	      for portable system commands.

       CMAKE_CURRENT_BINARY_DIR
	      The path to the binary directory currently being processed.

	      This the full path to the	 build	directory  that	 is  currently
	      being processed by cmake.	 Each directory added by add_subdirec‐
	      tory will create a binary directory in the build tree, and as it
	      is  being	 processed  this  variable will be set.	 For in-source
	      builds this is the current source directory being processed.

       CMAKE_CURRENT_LIST_DIR
	      Full directory of the listfile currently being processed.

	      As CMake processes the listfiles in your project	this  variable
	      will  always be set to the directory where the listfile which is
	      currently being processed (CMAKE_CURRENT_LIST_FILE) is  located.
	      The  value has dynamic scope.  When CMake starts processing com‐
	      mands in a source file it sets this variable  to	the  directory
	      where this file is located.  When CMake finishes processing com‐
	      mands from the file it restores the previous  value.   Therefore
	      the  value  of  the  variable  inside a macro or function is the
	      directory of the file invoking the bottom-most entry on the call
	      stack,  not  the	directory  of the file containing the macro or
	      function definition.

	      See also CMAKE_CURRENT_LIST_FILE.

       CMAKE_CURRENT_LIST_FILE
	      Full path to the listfile currently being processed.

	      As CMake processes the listfiles in your project	this  variable
	      will  always  be	set to the one currently being processed.  The
	      value has dynamic scope.	When CMake starts processing  commands
	      in  a  source  file it sets this variable to the location of the
	      file.  When CMake finishes processing commands from the file  it
	      restores	the  previous value.  Therefore the value of the vari‐
	      able inside a macro or function is the file  invoking  the  bot‐
	      tom-most	entry  on  the call stack, not the file containing the
	      macro or function definition.

	      See also CMAKE_PARENT_LIST_FILE.

       CMAKE_CURRENT_LIST_LINE
	      The line number of the current file being processed.

	      This is the line number of the file currently being processed by
	      cmake.

       CMAKE_CURRENT_SOURCE_DIR
	      The path to the source directory currently being processed.

	      This  the	 full  path  to the source directory that is currently
	      being processed by cmake.

       CMAKE_DL_LIBS
	      Name of library containing dlopen and dlcose.

	      The name of the library that has dlopen and dlclose in it,  usu‐
	      ally -ldl on most UNIX machines.

       CMAKE_EDIT_COMMAND
	      Full path to cmake-gui or ccmake.

	      This  is	the full path to the CMake executable that can graphi‐
	      cally edit the cache.  For example, cmake-gui, ccmake, or	 cmake
	      -i.

       CMAKE_EXECUTABLE_SUFFIX
	      The suffix for executables on this platform.

	      The  suffix to use for the end of an executable filename if any,
	      .exe on Windows.

	      CMAKE_EXECUTABLE_SUFFIX_<LANG>  overrides	 this	for   language
	      <LANG>.

       CMAKE_EXTRA_GENERATOR
	      The extra generator used to build the project.

	      When using the Eclipse, CodeBlocks or KDevelop generators, CMake
	      generates Makefiles (CMAKE_GENERATOR) and	 additionally  project
	      files for the respective IDE. This IDE project file generator is
	      stored in CMAKE_EXTRA_GENERATOR (e.g. "Eclipse CDT4").

       CMAKE_EXTRA_SHARED_LIBRARY_SUFFIXES
	      Additional suffixes for shared libraries.

	      Extensions for shared libraries other  than  that	 specified  by
	      CMAKE_SHARED_LIBRARY_SUFFIX,  if any.  CMake uses this to recog‐
	      nize external shared library files during analysis of  libraries
	      linked by a target.

       CMAKE_GENERATOR
	      The generator used to build the project.

	      The  name	 of  the  generator that is being used to generate the
	      build files.  (e.g. "Unix Makefiles", "Visual Studio 6", etc.)

       CMAKE_GENERATOR_TOOLSET
	      Native build system toolset name specified by user.

	      Some CMake generators support a toolset name to be given to  the
	      native build system to choose a compiler.	 If the user specifies
	      a toolset name (e.g. via the cmake -T option) the value will  be
	      available in this variable.

       CMAKE_HOME_DIRECTORY
	      Path to top of source tree.

	      This is the path to the top level of the source tree.

       CMAKE_IMPORT_LIBRARY_PREFIX
	      The prefix for import libraries that you link to.

	      The  prefix  to use for the name of an import library if used on
	      this platform.

	      The Minor version of cmake (i.e. the 4 in X.4.X).

	      This  specifies  the minor version of the CMake executable being
	      run.

       CMAKE_PARENT_LIST_FILE
	      Full path to the CMake file that included the current one.

	      While processing a CMake file loaded by include() or  find_pack‐
	      age() this variable contains the full path to the file including
	      it.  The top of the include stack is always  the	CMakeLists.txt
	      for the current directory.  See also CMAKE_CURRENT_LIST_FILE.

       CMAKE_PATCH_VERSION
	      The patch version of cmake (i.e. the 3 in X.X.3).

	      This  specifies  the patch version of the CMake executable being
	      run.

	      This specifies name of the  current  project  from  the  closest
	      inherited PROJECT command.

       CMAKE_RANLIB
	      Name of randomizing tool for static libraries.

	      This  specifies name of the program that randomizes libraries on
	      UNIX, not used on Windows, but may be present.

       CMAKE_ROOT
	      Install directory for running cmake.

	      This is the install root for the running CMake and  the  Modules
	      directory	 can be found here. This is commonly used in this for‐
	      mat: ${CMAKE_ROOT}/Modules

       CMAKE_SCRIPT_MODE_FILE
	      Full path to the -P script file currently being processed.

	      When run in -P script mode, CMake sets this variable to the full
	      path  of the script file. When run to configure a CMakeLists.txt
	      file, this variable is not set.

       CMAKE_SHARED_LIBRARY_PREFIX
	      The prefix for shared libraries that you link to.

	      The prefix to use for the name of a shared library, lib on UNIX.

	      The  suffix  to use for the end of a loadable module filename on
	      this platform

	      CMAKE_SHARED_MODULE_SUFFIX_<LANG> overrides  this	 for  language
	      <LANG>.

       CMAKE_SIZEOF_VOID_P
	      Size of a void pointer.

	      This  is	set  to	 the  size of a pointer on the machine, and is
	      determined by a try compile. If a 64 bit size is found, then the
	      library  search  path  is	 modified to look for 64 bit libraries
	      first.

       CMAKE_SKIP_RPATH
	      If true, do not add run time path information.

	      If this is set to TRUE, then the rpath information is not	 added
	      to  compiled  executables.  The default is to add rpath informa‐
	      tion if the platform supports it.	 This allows for easy  running
	      from the build tree.  To omit RPATH in the install step, but not
	      the build step, use CMAKE_SKIP_INSTALL_RPATH instead.

       CMAKE_SOURCE_DIR
	      The path to the top level of the source tree.

	      This is the full path to the top	level  of  the	current	 CMake
	      source  tree.  For an in-source build, this would be the same as
	      CMAKE_BINARY_DIR.

       CMAKE_STANDARD_LIBRARIES
	      Libraries linked into every executable and shared library.

	      This is the list of libraries that are linked into all  executa‐
	      bles and libraries.

       CMAKE_STATIC_LIBRARY_PREFIX
	      The prefix for static libraries that you link to.

	      <LANG>.

       CMAKE_STATIC_LIBRARY_SUFFIX
	      The suffix for static libraries that you link to.

	      The suffix to use for the end of a static library filename, .lib
	      on Windows.

	      CMAKE_STATIC_LIBRARY_SUFFIX_<LANG>  overrides  this for language
	      <LANG>.

       CMAKE_TWEAK_VERSION
	      The tweak version of cmake (i.e. the 1 in X.X.X.1).

	      This specifies the tweak version of the CMake  executable	 being
	      run.  Releases use tweak < 20000000 and development versions use
	      the date format CCYYMMDD for the tweak level.

       CMAKE_VERBOSE_MAKEFILE
	      Create verbose makefiles if on.

	      This variable defaults to false. You can set  this  variable  to
	      true to make CMake produce verbose makefiles that show each com‐
	      mand line as it is used.

       CMAKE_VERSION
	      The full version of cmake in major.minor.patch[.tweak[-id]] for‐
	      mat.

	      This  specifies  the  full version of the CMake executable being
	      run.  This variable is defined by	 versions  2.6.3  and  higher.
	      See    variables	  CMAKE_MAJOR_VERSION,	  CMAKE_MINOR_VERSION,
	      CMAKE_PATCH_VERSION, and CMAKE_TWEAK_VERSION for individual ver‐
	      sion  components.	  The  [-id]  component appears in non-release
	      versions and may be arbitrary text.

       CMAKE_VS_PLATFORM_TOOLSET
	      Visual Studio Platform Toolset name.

	      VS 10 and above use MSBuild under the hood and support  multiple
	      compiler	toolchains.   CMake  may specify a toolset explicitly,
	      such as "v110" for VS 11 or "Windows7.1SDK" for  64-bit  support
	      in VS 10 Express.	 CMake provides the name of the chosen toolset
	      in this variable.

       CMAKE_XCODE_PLATFORM_TOOLSET
	      Xcode compiler selection.

	      Xcode supports selection of a compiler from one of the installed
	      toolsets.	 CMake provides the name of the chosen toolset in this
	      variable, if any is explicitly selected (e.g. via the  cmake  -T
	      option).

       PROJECT_BINARY_DIR
	      Full path to build directory for project.

	      This is the binary directory of the most recent PROJECT command.

       PROJECT_NAME
	      Name of the project given to the project command.

	      This is the name given to the most recent PROJECT command.

       PROJECT_SOURCE_DIR
	      Top level source directory for the current project.

	      This is the source directory of the most recent PROJECT command.

       [Project name]_BINARY_DIR
	      Top level binary directory for the named project.

	      A variable is created with the name used in the PROJECT command,
	      and is the binary directory for the project.   This can be  use‐
	      ful when SUBDIR is used to connect several projects.

       [Project name]_SOURCE_DIR
	      Top level source directory for the named project.

	      A variable is created with the name used in the PROJECT command,
	      and is the source directory for the project.   This can be  use‐
	      ful when add_subdirectory is used to connect several projects.
