NAME
       cmakeprops - Reference of CMake properties.

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

		$<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.

		$<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.

       INSTALL_NAME_DIR
	      Mac OSX directory name for installed targets.

	      INSTALL_NAME_DIR is a string specifying the directory portion of
	      the "install_name" field of shared libraries on Mac OSX  to  use
	      in the installed targets.

       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	 prop‐
	      erty   is	  initialized	by   the   value   of	the   variable
	      CMAKE_INSTALL_RPATH if it is set when a target is created.

       INSTALL_RPATH_USE_LINK_PATH
	      Add paths to linker search and installed rpath.

	      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.	 This property is  initialized
	      by  the  value of the variable CMAKE_INSTALL_RPATH_USE_LINK_PATH
	      if it is set when a target is created.

       INTERFACE_COMPILE_DEFINITIONS
	      List of public compile definitions for a library.

	      Targets may populate this property to publish the compile	 defi‐
	      nitions  required to compile against the headers for the target.
	      Consuming targets can add entries to their  own  COMPILE_DEFINI‐
	      TIONS   property	such  as  $<TARGET_PROPERTY:foo,INTERFACE_COM‐
	      PILE_DEFINITIONS> to use the compile  definitions	 specified  in
	      the interface of 'foo'.

	      Generator	 expressions are evaluated during build system genera‐

		$<TARGET_LINKER_FILE_DIR:tgt>/$<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.

       INTERFACE_COMPILE_OPTIONS
	      List of interface options to pass to the compiler.

	      Targets may  populate  this  property  to	 publish  the  compile

       INTERFACE_POSITION_INDEPENDENT_CODE
	      Whether consumers need to create a position-independent target

	      PENDENT_CODE  property  to  ON.	If this property is set to ON,
	      then the POSITION_INDEPENDENT_CODE  property  on	all  consumers
	      will  be	set to ON.  Similarly, if this property is set to OFF,
	      then the POSITION_INDEPENDENT_CODE  property  on	all  consumers
	      will  be	set  to OFF.  If this property is undefined, then con‐
	      sumers will determine their  POSITION_INDEPENDENT_CODE  property
	      by  other	 means.	  Consumers  must ensure that the targets that
	      they link to have a  consistent  requirement  for	 their	INTER‐
	      FACE_POSITION_INDEPENDENT_CODE property.

       INTERFACE_SYSTEM_INCLUDE_DIRECTORIES
	      List of public system include directories for a library.

	      Targets may populate this property to publish the include direc‐
	      tories which contain system headers, and	therefore  should  not
	      result  in  compiler warnings.  Consuming targets will then mark

       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  overridden  by  the INTERFACE_LINK_LIBRARIES
	      property 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	 overridden  by	 the  INTERFACE_LINK_LIBRARIES
	      property 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.

	      Used to specify the .NET target framework version	 for  C++/CLI.
	      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.

       VS_SCC_LOCALPATH
	      Visual Studio Source Code Control Local Path.

	      Can be set to change the visual studio source code control local
	      path property.

       VS_SCC_PROJECTNAME
	      Visual Studio Source Code Control Project.

	      Can  be  set  to	change	the  visual studio source code control
	      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
		;	   - 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 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.
