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 Visual Studio Generators IDE generators.  It also allows the target names to
       be referenced unambiguously.

       Makefile generators are capable of supporting duplicate  add_custom_target()  names.   For
       projects  that  care  only  about  Makefile Generators and do not wish to support Xcode or
       Visual Studio Generators 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 produce an error and refuse to generate the project.

   AUTOGEN_SOURCE_GROUP
       Name of the  source_group() for AUTOMOC and AUTORCC generated files.

       Files  generated  by  AUTOMOC  and  AUTORCC  are  not  always  known at configure time and
       therefore can’t be passed to source_group().  AUTOGEN_SOURCE_GROUP an be used  instead  to
       generate or select a source group for AUTOMOC and AUTORCC generated files.

       For    AUTOMOC    and    AUTORCC   specific   overrides   see   AUTOMOC_SOURCE_GROUP   and
       AUTORCC_SOURCE_GROUP respectively.

   AUTOGEN_TARGETS_FOLDER
       Name of FOLDER for *_autogen targets that are added automatically 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.

   AUTOMOC_SOURCE_GROUP
       Name of the  source_group() for AUTOMOC generated files.

       When set this is used instead of AUTOGEN_SOURCE_GROUP for files generated by AUTOMOC.

   AUTOMOC_TARGETS_FOLDER
       Name of FOLDER for *_autogen targets that are added automatically by CMake for targets for
       which AUTOMOC is enabled.

       This property is obsolete.  Use AUTOGEN_TARGETS_FOLDER instead.

       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.

   AUTORCC_SOURCE_GROUP
       Name of the  source_group() for AUTORCC generated files.

       When set this is used instead of AUTOGEN_SOURCE_GROUP for files generated by AUTORCC.

   CMAKE_ROLE
       Tells what mode the current running script is in. Could be one of several values:

       PROJECT
              Running in project mode (processing a CMakeLists.txt file).

       SCRIPT Running in -P script mode.

       FIND_PACKAGE
              Running in --find-package mode.

       CTEST  Running in CTest script mode.

       CPACK  Running in CPack.

   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 target_link_libraries() command.  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_LIB32_PATHS
       Whether the find_library() command should automatically search lib32 directories.

       FIND_LIBRARY_USE_LIB32_PATHS is a boolean specifying whether  the  find_library()  command
       should automatically search the lib32 variant of directories called lib in the search path
       when building 32-bit binaries.

       See also the CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX variable.

   FIND_LIBRARY_USE_LIB64_PATHS
       Whether find_library() should automatically search lib64 directories.

       FIND_LIBRARY_USE_LIB64_PATHS is a boolean specifying whether  the  find_library()  command
       should automatically search the lib64 variant of directories called lib in the search path
       when building 64-bit binaries.

       See also the CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX variable.

   FIND_LIBRARY_USE_LIBX32_PATHS
       Whether the find_library() command should automatically search libx32 directories.

       FIND_LIBRARY_USE_LIBX32_PATHS is a boolean specifying whether the  find_library()  command
       should  automatically  search  the  libx32 variant of directories called lib in the search
       path when building x32-abi binaries.

       See also the CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX variable.

   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  versioned  extension:  “.so.<major>.<minor>”.  The
       property is set to true on OpenBSD and false on other platforms.

   GENERATOR_IS_MULTI_CONFIG
       Read-only property that is true on multi-configuration generators.

       True when using a multi-configuration generator  (such  as  Visual  Studio  Generators  or
       Xcode).    Multi-config   generators   use   CMAKE_CONFIGURATION_TYPES   as   the  set  of
       configurations and ignore CMAKE_BUILD_TYPE.

   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 configuration.

       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.

   JOB_POOLS
       Ninja only: List of available pools.

       A pool is a named integer property and defines the maximum number of concurrent jobs which
       can  be  started  by  a  rule  assigned  to  the  pool.   The  JOB_POOLS  property  is   a
       semicolon-separated list of pairs using the syntax NAME=integer (without a space after the
       equality sign).

       For instance:

          set_property(GLOBAL PROPERTY JOB_POOLS two_jobs=2 ten_jobs=10)

       Defined  pools  could   be   used   globally   by   setting   CMAKE_JOB_POOL_COMPILE   and
       CMAKE_JOB_POOL_LINK  or  per  target by setting the target properties JOB_POOL_COMPILE and
       JOB_POOL_LINK.  Custom commands and custom targets can  specify  pools  using  the  option
       JOB_POOL.  Using a pool that is not defined by JOB_POOLS causes an error by ninja at build
       time.

       If not set, this property uses the value of the CMAKE_JOB_POOLS variable.

       Build targets provided by CMake that are meant for individual  interactive  use,  such  as
       install, are placed in the console pool automatically.

   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 documentation for the FOLDER target property.

   ECLIPSE_EXTRA_NATURES
       List of natures to add to the generated Eclipse project file.

       Eclipse projects specify language plugins by using natures. This property should be set to
       the unique identifier for a nature (which looks like a Java package name).

       Also see the ECLIPSE_EXTRA_CPROJECT_CONTENTS property.

   ECLIPSE_EXTRA_CPROJECT_CONTENTS
       Additional contents to be inserted into the generated Eclipse cproject file.

       The cproject file defines the CDT specific information. Some third party IDE’s  are  based
       on  Eclipse  with  the  addition  of other information specific to that IDE.  Through this
       property, it is possible to add this additional contents to the generated project.  It  is
       expected to contain valid XML.

       Also see the ECLIPSE_EXTRA_NATURES 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  and  the  Ninja  generator  prefix  compiler commands with the given
       launcher command line.  This is intended to allow launchers to  intercept  build  problems
       with  high  granularity.   Other  generators ignore this property because their underlying
       build systems provide no hook to wrap individual commands with a launcher.

   RULE_LAUNCH_CUSTOM
       Specify a launcher for custom rules.

       Makefile Generators and the Ninja generator prefix custom commands with the given launcher
       command  line.   This is intended to allow launchers to intercept build problems with high
       granularity.  Other generators ignore this property because their underlying build systems
       provide no hook to wrap individual commands with a launcher.

   RULE_LAUNCH_LINK
       Specify a launcher for link rules.

       Makefile  Generators  and  the  Ninja  generator prefix link and archive commands with the
       given launcher command line.  This is intended  to  allow  launchers  to  intercept  build
       problems  with  high  granularity.   Other  generators  ignore this property because their
       underlying build systems provide no hook to wrap individual commands with a launcher.

   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 completes.
       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 property.  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 property is set to true on such
       platforms.

   TARGET_MESSAGES
       Specify whether to report the completion of each target.

       This property  specifies  whether  Makefile  Generators  should  add  a  progress  message
       describing that each target has been completed.  If the property is not set the default is
       ON.  Set the property to OFF to disable target completion messages.

       This option is intended to reduce build output when little or no work needs to be done  to
       bring the build tree up to date.

       If  a  CMAKE_TARGET_MESSAGES  cache  entry  exists its value initializes the value of this
       property.

       Non-Makefile generators currently ignore this property.

       See the counterpart  property  RULE_MESSAGES  to  disable  everything  except  for  target
       completion messages.

   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.

   XCODE_EMIT_EFFECTIVE_PLATFORM_NAME
       Control emission of EFFECTIVE_PLATFORM_NAME by the Xcode generator.

       It  is  required for building the same target with multiple SDKs. A common use case is the
       parallel use of iphoneos and iphonesimulator SDKs.

       Three  different  states  possible  that  control  when  the  Xcode  generator  emits  the
       EFFECTIVE_PLATFORM_NAME variable:

       • If set to ON it will always be emitted

       • If set to OFF it will never be emitted

       • If  unset  (the  default) it will only be emitted when the project was configured for an
         embedded Xcode SDK like iOS, tvOS, watchOS or any of the simulators.

       NOTE:
          When this behavior is enable for generated Xcode projects, the  EFFECTIVE_PLATFORM_NAME
          variable  will  leak  into Generator expressions like TARGET_FILE and will render those
          mostly unusable.

PROPERTIES ON DIRECTORIES

   ADDITIONAL_CLEAN_FILES
       A ;-list of files or directories that will be removed  as  a  part  of  the  global  clean
       target.   It  is  useful  for  specifying  generated files or directories that are used by
       multiple targets or by CMake itself, or  that  are  generated  in  ways  which  cannot  be
       captured as outputs or byproducts of custom commands.

       If   an   additional   clean   file  is  specific  to  a  single  target  only,  then  the
       ADDITIONAL_CLEAN_FILES target  property  would  usually  be  a  better  choice  than  this
       directory property.

       Relative paths are allowed and are interpreted relative to the current binary directory.

       Contents of ADDITIONAL_CLEAN_FILES may use generator expressions.

       This  property  only  works  for  the Ninja and the Makefile generators.  It is ignored by
       other generators.

   BINARY_DIR
       This  read-only  directory  property  reports  absolute  path  to  the  binary   directory
       corresponding to the source on which it is read.

   BUILDSYSTEM_TARGETS
       This  read-only  directory  property  contains  a  semicolon-separated list of buildsystem
       targets added in the directory  by  calls  to  the  add_library(),  add_executable(),  and
       add_custom_target()  commands.   The  list  does not include any Imported Targets or Alias
       Targets, but does include Interface Libraries.  Each entry in the list is the logical name
       of a target, suitable to pass to the get_property() command TARGET option.

   CACHE_VARIABLES
       List of cache variables available in the current directory.

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

   CLEAN_NO_CUSTOM
       Set to true to tell Makefile Generators not to remove the outputs of custom  commands  for
       this  directory  during  the  make  clean  operation.  This is ignored on other generators
       because it is not possible to implement.

   CMAKE_CONFIGURE_DEPENDS
       Tell CMake about additional input files to the configuration process.  If any  named  file
       is  modified  the build system will re-run CMake to re-configure the file and generate the
       build system again.

       Specify files as a semicolon-separated list of paths.  Relative paths are  interpreted  as
       relative to the current source directory.

   COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a directory’s sources.

       This  property specifies the list of options given so far to the add_compile_definitions()
       (or add_definitions()) command.

       The COMPILE_DEFINITIONS property may be set to a semicolon-separated 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  will  be  initialized  in  each  directory by its value in the directory’s
       parent.

       CMake will automatically drop some definitions that are not supported by the native  build
       tool.

       Disclaimer:  Most native build tools have poor support for escaping 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.

       Contents of COMPILE_DEFINITIONS may use “generator expressions” with  the  syntax  $<...>.
       See   the  cmake-generator-expressions(7)  manual  for  available  expressions.   See  the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       The  corresponding  COMPILE_DEFINITIONS_<CONFIG>  property   may   be   set   to   specify
       per-configuration  definitions.   Generator  expressions  should  be  preferred instead of
       setting the alternative property.

   COMPILE_OPTIONS
       List of options to pass to the compiler.

       This  property  holds  a  semicolon-separated  list  of  options  given  so  far  to   the
       add_compile_options() command.

       This  property  is used to initialize the COMPILE_OPTIONS target property when a target is
       created, which is used by the generators to set the options for the compiler.

       Contents of COMPILE_OPTIONS may use “generator expressions” with the syntax  $<...>.   See
       the   cmake-generator-expressions(7)   manual   for   available   expressions.    See  the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   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 directory
       property instead.

       This built-in read-only property does not exist if policy CMP0059 is set to NEW.

   EXCLUDE_FROM_ALL
       Set this directory property to a true value on a subdirectory to exclude its targets  from
       the “all” target of its ancestors.  If excluded, running e.g. make in the parent directory
       will not build targets the subdirectory by default.  This does not affect the “all” target
       of  the  subdirectory  itself.  Running e.g. make inside the subdirectory will still build
       its targets.

       If the EXCLUDE_FROM_ALL target property is set on  a  target  then  its  value  determines
       whether the target is included in the “all” target of this directory and its ancestors.

   IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
       Specify #include line transforms for dependencies in a directory.

       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
       literal).  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 directory.  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 is used to populate the INCLUDE_DIRECTORIES target property, which  is  used
       by the generators to set the include directories for the compiler.

       In  addition  to  accepting  values  from  that command, values may be set directly on any
       directory using the set_property() command, and can be set on the current directory  using
       the  set_directory_properties()  command.   A  directory  gets  its initial value from its
       parent directory if it has one.  The  initial  value  of  the  INCLUDE_DIRECTORIES  target
       property comes from the value of this property.  Both directory and target property values
       are adjusted by calls to the include_directories() command.  Calls  to  set_property()  or
       set_directory_properties(),  however,  will  update  the  directory property value without
       updating target property values.  Therefore direct property updates must  be  made  before
       calls to add_executable() or add_library() for targets they are meant to affect.

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

       Contents of INCLUDE_DIRECTORIES may use “generator expressions” with  the  syntax  $<...>.
       See   the  cmake-generator-expressions(7)  manual  for  available  expressions.   See  the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   INCLUDE_REGULAR_EXPRESSION
       Include file scanning regular expression.

       This property specifies the regular expression used during dependency  scanning  to  match
       include files that should be followed.  See the include_regular_expression() command for a
       high-level interface to set this property.

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

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

   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.

   LABELS
       Specify a list of text labels associated with a directory and all of  its  subdirectories.
       This  is  equivalent to setting the LABELS target property and the LABELS test property on
       all targets and tests in the current directory and subdirectories.  Note:  Launchers  must
       enabled to propagate labels to targets.

       The CMAKE_DIRECTORY_LABELS variable can be used to initialize this property.

       The list is reported in dashboard submissions.

   LINK_DIRECTORIES
       List of linker search directories.

       This  property  holds a semicolon-separated list of directories and is typically populated
       using the  link_directories()  command.   It  gets  its  initial  value  from  its  parent
       directory, if it has one.

       The  directory  property is used to initialize the LINK_DIRECTORIES target property when a
       target is created.  That target property is used by the  generators  to  set  the  library
       search directories for the linker.

       Contents  of LINK_DIRECTORIES may use “generator expressions” with the syntax $<...>.  See
       the  cmake-generator-expressions(7)   manual   for   available   expressions.    See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   LINK_OPTIONS
       List of options to use for the link step of shared library, module and executable targets.

       This   property  holds  a  semicolon-separated  list  of  options  given  so  far  to  the
       add_link_options() command.

       This property is used to initialize the LINK_OPTIONS target  property  when  a  target  is
       created, which is used by the generators to set the options for the compiler.

       Contents  of LINK_OPTIONS may use “generator expressions” with the syntax $<...>.  See the
       cmake-generator-expressions(7)   manual    for    available    expressions.     See    the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   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  currently  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.

   SOURCE_DIR
       This read-only directory property reports absolute path to the source directory  on  which
       it is read.

   SUBDIRECTORIES
       This  read-only  directory  property contains a semicolon-separated list of subdirectories
       processed so far by the add_subdirectory() or  subdirs()  commands.   Each  entry  is  the
       absolute  path  to  the  source  directory  (containing the CMakeLists.txt file).  This is
       suitable to pass to the get_property() command DIRECTORY option.

       NOTE:
          The subdirs() command does not process its arguments until after the calling  directory
          is  fully  processed.  Therefore looking up this property in the current directory will
          not see them.

   TESTS
       List of tests.

       This read-only property holds a semicolon-separated list of tests defined so far,  in  the
       current directory, by the add_test() command.

   TEST_INCLUDE_FILES
       A list of cmake files that will be included when ctest is run.

       If  you  specify TEST_INCLUDE_FILES, those files 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 9 and above; it is ignored on other generators.
       The  property  only  applies  when  set  on  a  directory  whose CMakeLists.txt contains a
       project() command.

       Note   that   CMake   generates    postSolution    sections    ExtensibilityGlobals    and
       ExtensibilityAddIns  by  default.  If you set the corresponding 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.  However, CMake will always add a SolutionGuid to  the
       ExtensibilityGlobals section if it is not specified explicitly.

   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 9 and above; it is ignored on other generators.
       The  property  only  applies  when  set  on  a  directory  whose CMakeLists.txt contains a
       project() command.

   VS_STARTUP_PROJECT
       Specify the default startup project in a Visual Studio solution.

       The Visual Studio Generators create a .sln file for each  directory  whose  CMakeLists.txt
       file  calls the project() command.  Set this property in the same directory as a project()
       command call (e.g. in the top-level CMakeLists.txt file) to specify  the  default  startup
       project for the corresponding solution file.

       The  property must be set to the name of an existing target.  This will cause that project
       to be listed first in the generated solution file causing Visual Studio  to  make  it  the
       startup project if the solution has never been opened before.

       If this property is not specified, then the ALL_BUILD project will be the default.

PROPERTIES ON TARGETS

   ADDITIONAL_CLEAN_FILES
       A  ;-list  of  files  or  directories  that  will be removed as a part of the global clean
       target.  It can be used to specify files and directories that are  generated  as  part  of
       building  the  target  or  that  are directly associated with the target in some way (e.g.
       created as a result of running the target).

       For custom targets, if such files can be captured as outputs or byproducts  instead,  then
       that  should  be preferred over adding them to this property.  If an additional clean file
       is used by multiple targets or  isn’t  target-specific,  then  the  ADDITIONAL_CLEAN_FILES
       directory property may be the more appropriate property to use.

       Relative paths are allowed and are interpreted relative to the current binary directory.

       Contents of ADDITIONAL_CLEAN_FILES may use generator expressions.

       This  property  only  works  for  the Ninja and the Makefile generators.  It is ignored by
       other generators.

   ALIASED_TARGET
       Name of target aliased by this target.

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

   ANDROID_ANT_ADDITIONAL_OPTIONS
       Set the additional options for Android Ant build system. This is a string value containing
       all  command line options for the Ant build.  This property is initialized by the value of
       the CMAKE_ANDROID_ANT_ADDITIONAL_OPTIONS variable if it is set when a target is created.

   ANDROID_API
       When Cross Compiling for Android with NVIDIA Nsight  Tegra  Visual  Studio  Edition,  this
       property  sets  the  Android  target  API version (e.g. 15).  The version number must be a
       positive  decimal  integer.   This  property  is  initialized  by   the   value   of   the
       CMAKE_ANDROID_API variable if it is set when a target is created.

   ANDROID_API_MIN
       Set  the  Android MIN API version (e.g. 9).  The version number must be a positive decimal
       integer.  This property is initialized by the value of the CMAKE_ANDROID_API_MIN  variable
       if it is set when a target is created.  Native code builds using this API version.

   ANDROID_ARCH
       When  Cross  Compiling  for  Android  with NVIDIA Nsight Tegra Visual Studio Edition, this
       property sets the Android target architecture.

       This is a string property that could be set to the one of the following values:

       • armv7-a: “ARMv7-A (armv7-a)”

       • armv7-a-hard: “ARMv7-A, hard-float ABI (armv7-a)”

       • arm64-v8a: “ARMv8-A, 64bit (arm64-v8a)”

       • x86: “x86 (x86)”

       • x86_64: “x86_64 (x86_64)”

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

   ANDROID_ASSETS_DIRECTORIES
       Set  the Android assets directories to copy into the main assets folder before build. This
       a string property that contains the directory paths separated by semicolon.  This property
       is  initialized by the value of the CMAKE_ANDROID_ASSETS_DIRECTORIES variable if it is set
       when a target is created.

   ANDROID_GUI
       When Cross Compiling for Android with NVIDIA Nsight  Tegra  Visual  Studio  Edition,  this
       property specifies whether to build an executable as an application package on Android.

       When this property is set to true the executable when built for Android will be created as
       an  application  package.   This  property  is   initialized   by   the   value   of   the
       CMAKE_ANDROID_GUI variable if it is set when a target is created.

       Add  the AndroidManifest.xml source file explicitly to the target add_executable() command
       invocation to specify the root directory of the application package source.

   ANDROID_JAR_DEPENDENCIES
       Set the Android property  that  specifies  JAR  dependencies.   This  is  a  string  value
       property.  This property is initialized by the value of the CMAKE_ANDROID_JAR_DEPENDENCIES
       variable if it is set when a target is created.

   ANDROID_JAR_DIRECTORIES
       Set the Android property that specifies directories to search for the JAR libraries.

       This a string property that contains the directory paths  separated  by  semicolons.  This
       property  is  initialized by the value of the CMAKE_ANDROID_JAR_DIRECTORIES variable if it
       is set when a target is created.

       Contents of ANDROID_JAR_DIRECTORIES  may  use  “generator  expressions”  with  the  syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.

   ANDROID_JAVA_SOURCE_DIR
       Set  the  Android  property  that  defines  the Java source code root directories.  This a
       string property that contains the directory paths separated by semicolon.   This  property
       is  initialized  by  the  value of the CMAKE_ANDROID_JAVA_SOURCE_DIR variable if it is set
       when a target is created.

   ANDROID_NATIVE_LIB_DEPENDENCIES
       Set the Android property that specifies the .so dependencies.  This is a string property.

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

       Contents  of  ANDROID_NATIVE_LIB_DEPENDENCIES  may  use  “generator  expressions” with the
       syntax $<...>. See the cmake-generator-expressions(7) manual for available expressions.

   ANDROID_NATIVE_LIB_DIRECTORIES
       Set the Android property that specifies directories to search for the .so libraries.

       This a string property that contains the directory paths separated by semicolons.

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

       Contents of ANDROID_NATIVE_LIB_DIRECTORIES may use “generator expressions” with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.

   ANDROID_PROCESS_MAX
       Set the Android property that defines  the  maximum  number  of  a  parallel  Android  NDK
       compiler  processes  (e.g.  4).   This  property  is  initialized  by  the  value  of  the
       CMAKE_ANDROID_PROCESS_MAX variable if it is set when a target is created.

   ANDROID_PROGUARD
       When this property is set to true that enables the ProGuard tool to shrink, optimize,  and
       obfuscate  the code by removing unused code and renaming classes, fields, and methods with
       semantically  obscure  names.   This  property  is  initialized  by  the  value   of   the
       CMAKE_ANDROID_PROGUARD variable if it is set when a target is created.

   ANDROID_PROGUARD_CONFIG_PATH
       Set  the  Android  property that specifies the location of the ProGuard config file. Leave
       empty to use the default one.  This a string property that contains the path  to  ProGuard
       config    file.     This    property    is    initialized    by    the    value   of   the
       CMAKE_ANDROID_PROGUARD_CONFIG_PATH variable if it is set when a target is created.

   ANDROID_SECURE_PROPS_PATH
       Set the Android property that states the location of the secure properties file.  This  is
       a  string property that contains the file path.  This property is initialized by the value
       of the CMAKE_ANDROID_SECURE_PROPS_PATH variable if it is set when a target is created.

   ANDROID_SKIP_ANT_STEP
       Set the Android property that defines whether or not to skip the Ant build step.  This  is
       a boolean property initialized by the value of the CMAKE_ANDROID_SKIP_ANT_STEP variable if
       it is set when a target is created.

   ANDROID_STL_TYPE
       When Cross Compiling for Android with NVIDIA Nsight  Tegra  Visual  Studio  Edition,  this
       property  specifies  the  type  of STL support for the project.  This is a string property
       that could set to the one of the following values:

       none   No C++ Support

       system Minimal C++ without STL

       gabi++_static
              GAbi++ Static

       gabi++_shared
              GAbi++ Shared

       gnustl_static
              GNU libstdc++ Static

       gnustl_shared
              GNU libstdc++ Shared

       stlport_static
              STLport Static

       stlport_shared
              STLport Shared

       This property is initialized by the value of the CMAKE_ANDROID_STL_TYPE variable 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 the ARCHIVE_OUTPUT_DIRECTORY target property, 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
       CMAKE_ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> variable if it is set when a target is created.

       Contents of ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> may use generator expressions.

   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.
       The  property  value  may  use generator expressions.  Multi-configuration generators (VS,
       Xcode) append a  per-configuration  subdirectory  to  the  specified  directory  unless  a
       generator expression is used.

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

       See also the ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> target property.

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

       This is the configuration-specific version of the ARCHIVE_OUTPUT_NAME target property.

   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.

       See also the ARCHIVE_OUTPUT_NAME_<CONFIG> target property.

   AUTOGEN_BUILD_DIR
       Directory where AUTOMOC, AUTOUIC and AUTORCC generate files for the target.

       The  directory  is created on demand and automatically added to the ADDITIONAL_CLEAN_FILES
       target property.

       When unset or empty the directory  <dir>/<target-name>_autogen  is  used  where  <dir>  is
       CMAKE_CURRENT_BINARY_DIR and <target-name> is NAME.

       By default AUTOGEN_BUILD_DIR is unset.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOGEN_ORIGIN_DEPENDS
       Switch for forwarding origin target dependencies to the corresponding _autogen target.

       Targets  which  have  their  AUTOMOC  or AUTOUIC property ON have a corresponding _autogen
       target which generates moc  and  uic  files.   As  this  _autogen  target  is  created  at
       generate-time,   it   is   not   possible   to   define  dependencies  of  it  using  e.g.
       add_dependencies().  Instead the AUTOGEN_ORIGIN_DEPENDS target  property  decides  whether
       the origin target dependencies should be forwarded to the _autogen target or not.

       By  default  AUTOGEN_ORIGIN_DEPENDS is initialized from CMAKE_AUTOGEN_ORIGIN_DEPENDS which
       is ON by default.

       In total the dependencies of the _autogen target are composed from

       • forwarded origin target dependencies (enabled by default via AUTOGEN_ORIGIN_DEPENDS)

       • additional user defined dependencies from AUTOGEN_TARGET_DEPENDS

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   Note
       Disabling AUTOGEN_ORIGIN_DEPENDS is useful to avoid building of origin target dependencies
       when  building  the  _autogen  target  only.  This is especially interesting when a global
       autogen target is enabled.

       When the _autogen target  doesn’t  require  all  the  origin  target’s  dependencies,  and
       AUTOGEN_ORIGIN_DEPENDS is disabled, it might be necessary to extend AUTOGEN_TARGET_DEPENDS
       to add missing dependencies.

   AUTOGEN_PARALLEL
       Number of parallel moc or uic processes to start when using AUTOMOC and AUTOUIC.

       The custom <origin>_autogen target starts a number of threads of which each one  parses  a
       source file and on demand starts a moc or uic process.  AUTOGEN_PARALLEL controls how many
       parallel threads (and therefore moc or uic processes) are started.

       • An empty (or unset) value or the string AUTO sets the number of threads/processes to the
         number of physical CPUs on the host system.

       • A positive non zero integer value sets the exact thread/process count.

       • Otherwise a single thread/process is started.

       By default AUTOGEN_PARALLEL is initialized from CMAKE_AUTOGEN_PARALLEL.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOGEN_TARGET_DEPENDS
       Additional target dependencies of the corresponding _autogen target.

       Targets  which  have  their  AUTOMOC  or AUTOUIC property ON have a corresponding _autogen
       target which generates moc  and  uic  files.   As  this  _autogen  target  is  created  at
       generate-time,   it   is   not   possible   to   define  dependencies  of  it  using  e.g.
       add_dependencies().  Instead the AUTOGEN_TARGET_DEPENDS target property can be  set  to  a
       ;-list  of  additional  dependencies  for the _autogen target.  Dependencies can be target
       names or file names.

       In total the dependencies of the _autogen target are composed from

       • forwarded origin target dependencies (enabled by default via AUTOGEN_ORIGIN_DEPENDS)

       • additional user defined dependencies from AUTOGEN_TARGET_DEPENDS

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   Use cases
       If AUTOMOC or AUTOUIC depends on a file that is either

       • a GENERATED non C++ file (e.g. a GENERATED .json or .ui file) or

       • a GENERATED C++ file that isn’t recognized by AUTOMOC and AUTOUIC because  it’s  skipped
         by SKIP_AUTOMOC, SKIP_AUTOUIC, SKIP_AUTOGEN or CMP0071 or

       • a file that isn’t in the origin target’s sources

       it must added to AUTOGEN_TARGET_DEPENDS.

   AUTOMOC_COMPILER_PREDEFINES
       Boolean  value  used  by  AUTOMOC  to  determine  if  the  compiler  pre  definitions file
       moc_predefs.h should be generated.

       CMake generates a moc_predefs.h file with compiler pre definitions from the output of  the
       command defined in CMAKE_CXX_COMPILER_PREDEFINES_COMMAND when

       • AUTOMOC is enabled,

       • AUTOMOC_COMPILER_PREDEFINES is enabled,

       • CMAKE_CXX_COMPILER_PREDEFINES_COMMAND isn’t empty and

       • the Qt version is greater or equal 5.8.

       The  moc_predefs.h  file, which is generated in AUTOGEN_BUILD_DIR, is passed to moc as the
       argument to the --include option.

       By       default       AUTOMOC_COMPILER_PREDEFINES       is        initialized        from
       CMAKE_AUTOMOC_COMPILER_PREDEFINES, which is ON by default.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOMOC_DEPEND_FILTERS
       Filter  definitions  used  by  AUTOMOC  to  extract file names from a source file that are
       registered as additional dependencies for the moc file of the source file.

       Filters are defined  as  KEYWORD;REGULAR_EXPRESSION  pairs.  First  the  file  content  is
       searched  for  KEYWORD.  If  it  is  found at least once, then file names are extracted by
       successively searching for REGULAR_EXPRESSION and taking the first match group.

       The file name found in the first match group is searched for

       • first in the vicinity of the source file

       • and afterwards in the target’s INCLUDE_DIRECTORIES.

       If any of the extracted files changes, then the moc file for the source file gets  rebuilt
       even when the source file itself doesn’t change.

       If  any  of the extracted files is GENERATED or if it is not in the target’s sources, then
       it  might  be  necessary  to  add  it  to  the   _autogen   target    dependencies.    See
       AUTOGEN_TARGET_DEPENDS for reference.

       By  default AUTOMOC_DEPEND_FILTERS is initialized from CMAKE_AUTOMOC_DEPEND_FILTERS, which
       is empty by default.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   Example 1
       A header file my_class.hpp uses a custom macro JSON_FILE_MACRO  which  is  defined  in  an
       other  header macros.hpp.  We want the moc file of my_class.hpp to depend on the file name
       argument of JSON_FILE_MACRO:

          // my_class.hpp
          class My_Class : public QObject
          {
            Q_OBJECT
            JSON_FILE_MACRO ( "info.json" )
          ...
          };

       In CMakeLists.txt we add a filter to CMAKE_AUTOMOC_DEPEND_FILTERS like this:

          list( APPEND CMAKE_AUTOMOC_DEPEND_FILTERS
            "JSON_FILE_MACRO"
            "[\n][ \t]*JSON_FILE_MACRO[ \t]*\\([ \t]*\"([^\"]+)\""
          )

       We assume info.json is a plain (not GENERATED) file that is listed in the target’s source.
       Therefore we do not need to add it to AUTOGEN_TARGET_DEPENDS.

   Example 2
       In   the   target   my_target   a  header  file  complex_class.hpp  uses  a  custom  macro
       JSON_BASED_CLASS which is defined in an other header macros.hpp:

          // macros.hpp
          ...
          #define JSON_BASED_CLASS(name, json) \
          class name : public QObject \
          { \
            Q_OBJECT \
            Q_PLUGIN_METADATA(IID "demo" FILE json) \
            name() {} \
          };
          ...

          // complex_class.hpp
          #pragma once
          JSON_BASED_CLASS(Complex_Class, "meta.json")
          // end of file

       Since complex_class.hpp doesn’t contain a Q_OBJECT macro it would be ignored  by  AUTOMOC.
       We change this by adding JSON_BASED_CLASS to CMAKE_AUTOMOC_MACRO_NAMES:

          list(APPEND CMAKE_AUTOMOC_MACRO_NAMES "JSON_BASED_CLASS")

       We  want  the moc file of complex_class.hpp to depend on meta.json.  So we add a filter to
       CMAKE_AUTOMOC_DEPEND_FILTERS:

          list(APPEND CMAKE_AUTOMOC_DEPEND_FILTERS
            "JSON_BASED_CLASS"
            "[\n^][ \t]*JSON_BASED_CLASS[ \t]*\\([^,]*,[ \t]*\"([^\"]+)\""
          )

       Additionally we assume meta.json  is  GENERATED  which  is  why  we  have  to  add  it  to
       AUTOGEN_TARGET_DEPENDS:

          set_property(TARGET my_target APPEND PROPERTY AUTOGEN_TARGET_DEPENDS "meta.json")

   AUTOMOC_EXECUTABLE
       AUTOMOC_EXECUTABLE  is file path pointing to the moc executable to use for AUTOMOC enabled
       files. Setting this property will make CMake skip  the  automatic  detection  of  the  moc
       binary as well as the sanity-tests normally run to ensure that the binary is available and
       working as expected.

       Usually  this  property  does  not  need  to  be  set.  Only  consider  this  property  if
       auto-detection  of moc can not work – e.g. because you are building the moc binary as part
       of your project.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOMOC_MACRO_NAMES
       A semicolon-separated list list of macro names used by AUTOMOC to determine if a C++  file
       needs to be processed by moc.

       This property is only used if the AUTOMOC property is ON for this target.

       When  running AUTOMOC, CMake searches for the strings listed in AUTOMOC_MACRO_NAMES in C++
       source and header files.  If any of the strings is found

       • as the first non space string on a new line or

       • as the first non space string after a { on a new line,

       then the file will be processed by moc.

       By default AUTOMOC_MACRO_NAMES is initialized from CMAKE_AUTOMOC_MACRO_NAMES.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   Example
       In this case the Q_OBJECT macro is hidden inside another macro  called  CUSTOM_MACRO.   To
       let  CMake  know  that source files that contain CUSTOM_MACRO need to be moc processed, we
       call:

          set_property(TARGET tgt APPEND PROPERTY AUTOMOC_MACRO_NAMES "CUSTOM_MACRO")

   AUTOMOC_MOC_OPTIONS
       Additional options for moc when using AUTOMOC

       This property is only used if the AUTOMOC property is ON 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.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOMOC_PATH_PREFIX
       When this property is ON, CMake will generate the -p path prefix option for moc on AUTOMOC
       enabled Qt targets.

       To generate the path prefix, CMake tests if the header compiled by moc is in  any  of  the
       target  include directories.  If so, CMake will compute the relative path accordingly.  If
       the header is not in the include directories, CMake will omit the -p path  prefix  option.
       moc usually generates a relative include path in that case.

       AUTOMOC_PATH_PREFIX  is  initialized from the variable CMAKE_AUTOMOC_PATH_PREFIX, which is
       ON by default.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   Reproducible builds
       For reproducible builds is is recommended to keep headers that are moc compiled in one  of
       the  target  include directories and set AUTOMOC_PATH_PREFIX to ON (which is the default).
       This ensures that

       • moc output files are identical on different build setups,

       • moc output files will compile correctly when the source  and/or  build  directory  is  a
         symbolic link.

   AUTOMOC
       Should the target be processed with auto-moc (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.

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

       When this property is set ON, CMake will scan the header and source files  at  build  time
       and invoke moc accordingly.

   Header file processing
       At  configuration  time,  a  list  of  header  files  that should be scanned by AUTOMOC is
       computed from the target’s sources.

       • All header files in the target’s sources are added to the scan list.

       • For all C++ source files <source_base>.<source_extension> in the target’s sources, CMake
         searches for

         • a regular header with the same base name (<source_base>.<header_extention>) and

         • a    private    header    with    the    same    base    name    and   a   _p   suffix
           (<source_base>_p.<header_extention>)

         and adds these to the scan list.

       At build time, CMake scans each unknown or modified header file from the list and searches
       for

       • a Qt macro from AUTOMOC_MACRO_NAMES,

       • additional file dependencies from the FILE argument of a Q_PLUGIN_METADATA macro and

       • additional file dependencies detected by filters defined in AUTOMOC_DEPEND_FILTERS.

       If  a  Qt  macro  is found, then the header will be compiled by the moc to the output file
       moc_<base_name>.cpp.  The complete output file path is described  in  the  section  Output
       file location.

       The  header  will  be  moc  compiled again if a file from the additional file dependencies
       changes.

       Header moc output files moc_<base_name>.cpp can be  included  in  source  files.   In  the
       section Including header moc files in sources there is more information on that topic.

   Source file processing
       At  build  time,  CMake  scans  each unknown or modified C++ source file from the target’s
       sources for

       • a Qt macro from AUTOMOC_MACRO_NAMES,

       • includes of header moc files (see Including header moc files in sources),

       • additional file dependencies from the FILE argument of a Q_PLUGIN_METADATA macro and

       • additional file dependencies detected by filters defined in AUTOMOC_DEPEND_FILTERS.

       If a Qt macro is found, then the C++ source file <base>.<source_extension> is expected  to
       as well contain an include statement

          #include <<base>.moc> // or
          #include "<base>.moc"

       The  source  file  then  will  be  compiled  by  the moc to the output file <base>.moc.  A
       description of the complete output file path is in section Output file location.

       The source will be moc compiled again if a file  from  the  additional  file  dependencies
       changes.

   Including header moc files in sources
       A source file can include the moc output file of a header <header_base>.<header_extension>
       by using an include statement of the form

          #include <moc_<header_base>.cpp> // or
          #include "moc_<header_base>.cpp"

       If the moc output file of a header is included by a source, it  will  be  generated  in  a
       different  location  than if it was not included.  This is described in the section Output
       file location.

   Output file location
   Included moc output files
       moc output files that are included by a source file will be generated in

       • <AUTOGEN_BUILD_DIR>/include for single configuration generators or in

       • <AUTOGEN_BUILD_DIR>/include_<CONFIG> for multi configuration generators.

       Where <AUTOGEN_BUILD_DIR> is the value of the target property AUTOGEN_BUILD_DIR.

       The include directory is automatically added to the target’s INCLUDE_DIRECTORIES.

   Not included moc output files
       moc output files that are not included in a source file will be generated in

       • <AUTOGEN_BUILD_DIR>/<SOURCE_DIR_CHECKSUM> for single configuration generators or in,

       • <AUTOGEN_BUILD_DIR>/include_<CONFIG>/<SOURCE_DIR_CHECKSUM>   for   multi   configuration
         generators.

       Where <SOURCE_DIR_CHECKSUM> is a checksum computed from the relative parent directory path
       of the moc input file.  This scheme allows to have moc input files with the same  name  in
       different directories.

       All  not  included  moc output files will be included automatically by the CMake generated
       file

       • <AUTOGEN_BUILD_DIR>/mocs_compilation.cpp,

       which is added to the target’s sources.

   Qt version detection
       AUTOMOC enabled targets need to know the Qt major and minor version they’re working  with.
       The  major  version  usually is provided by the INTERFACE_QT_MAJOR_VERSION property of the
       Qt[45]Core library, that the target links to.  To find the minor version, CMake  builds  a
       list of available Qt versions from

       • Qt5Core_VERSION_MAJOR    and    Qt5Core_VERSION_MINOR    variables   (usually   set   by
         find_package(Qt5...))

       • Qt5Core_VERSION_MAJOR and Qt5Core_VERSION_MINOR directory properties

       • QT_VERSION_MAJOR and QT_VERSION_MINOR  variables (usually set by find_package(Qt4...))

       • QT_VERSION_MAJOR and QT_VERSION_MINOR  directory properties

       in the context of the add_executable() or add_library() call.

       Assumed  INTERFACE_QT_MAJOR_VERSION is a valid number, the first entry in the list with  a
       matching  major  version  is  taken.   If no matching major version was found, an error is
       generated.  If  INTERFACE_QT_MAJOR_VERSION is not a valid number, the first entry  in  the
       list is taken.

       A  find_package(Qt[45]...) call sets the QT/Qt5Core_VERSION_MAJOR/MINOR variables.  If the
       call is in a different context than the add_executable() or add_library() call, e.g. in  a
       function, then the version variables might not be available to the AUTOMOC enabled target.
       In that case the version variables can be forwarded from the find_package(Qt[45]…) calling
       context  to the add_executable() or add_library() calling context as directory properties.
       The following Qt5 example demonstrates the procedure.

          function (add_qt5_client)
            find_package(Qt5 REQUIRED QUIET COMPONENTS Core Widgets)
            ...
            set_property(DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}"
              PROPERTY Qt5Core_VERSION_MAJOR "${Qt5Core_VERSION_MAJOR}")
            set_property(DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}"
              PROPERTY Qt5Core_VERSION_MINOR "${Qt5Core_VERSION_MAJOR}")
            ...
          endfunction ()
          ...
          add_qt5_client()
          add_executable(myTarget main.cpp)
          target_link_libraries(myTarget Qt5::QtWidgets)
          set_property(TARGET myTarget PROPERTY AUTOMOC ON)

   Modifiers
       AUTOMOC_EXECUTABLE: The moc executable will be detected automatically, but can  be  forced
       to a certain binary using this target property.

       AUTOMOC_MOC_OPTIONS:  Additional  command  line  options for moc can be set in this target
       property.

       AUTOMOC_MACRO_NAMES: This list of Qt macro names can be extended to search for  additional
       macros in headers and sources.

       AUTOMOC_DEPEND_FILTERS: moc dependency file names can be extracted from headers or sources
       by defining file name filters in this target property.

       AUTOMOC_COMPILER_PREDEFINES:  Compiler  pre  definitions  for  moc  are  written  to   the
       moc_predefs.h file.  The generation of this file can be enabled or disabled in this target
       property.

       SKIP_AUTOMOC: Sources and headers can be excluded from AUTOMOC processing by setting  this
       source file property.

       SKIP_AUTOGEN: Source files can be excluded from AUTOMOC, AUTOUIC and AUTORCC processing by
       setting this source file property.

       AUTOGEN_SOURCE_GROUP: This global property can be used to group files generated by AUTOMOC
       or AUTORCC together in an IDE, e.g.  in MSVS.

       AUTOGEN_TARGETS_FOLDER:  This  global  property  can be used to group AUTOMOC, AUTOUIC and
       AUTORCC targets together in an IDE, e.g.  in MSVS.

       CMAKE_GLOBAL_AUTOGEN_TARGET: A global autogen target,  that  depends  on  all  AUTOMOC  or
       AUTOUIC  generated  <ORIGIN>_autogen  targets  in the project, will be generated when this
       variable is ON.

       AUTOGEN_PARALLEL: This target property controls the number of  moc  or  uic  processes  to
       start in parallel during builds.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOUIC
       Should the target be processed with auto-uic (for Qt projects).

       AUTOUIC  is  a  boolean  specifying  whether  CMake  will handle the Qt uic code generator
       automatically, i.e. without having  to  use  the  QT4_WRAP_UI()  or  QT5_WRAP_UI()  macro.
       Currently Qt4 and Qt5 are supported.

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

       When this property is ON, CMake will scan the header and source files at  build  time  and
       invoke uic accordingly.

   Header and source file processing
       At  build  time,  CMake  scans  each  header and source file from the target’s sources for
       include statements of the form

          #include "ui_<ui_base>.h"

       Once such an include statement is found in a file, CMake searches for the uic  input  file
       <ui_base>.ui

       • in the vicinity of the file and

       • in the AUTOUIC_SEARCH_PATHS of the target.

       If  the <ui_base>.ui file was found, uic is called on it to generate ui_<ui_base>.h in the
       directory

       • <AUTOGEN_BUILD_DIR>/include for single configuration generators or in

       • <AUTOGEN_BUILD_DIR>/include_<CONFIG> for multi configuration generators.

       Where <AUTOGEN_BUILD_DIR> is the value of the target property AUTOGEN_BUILD_DIR.

       The include directory is automatically added to the target’s INCLUDE_DIRECTORIES.

   Modifiers
       AUTOUIC_EXECUTABLE: The uic executable will be detected automatically, but can  be  forced
       to a certain binary using this target property.

       AUTOUIC_OPTIONS:  Additional  command line options for uic can be set via this source file
       property on a <base_name>.ui file.

       SKIP_AUTOUIC: Source files can be excluded from AUTOUIC processing by setting this  source
       file property.

       SKIP_AUTOGEN: Source files can be excluded from AUTOMOC, AUTOUIC and AUTORCC processing by
       setting this source file property.

       AUTOGEN_TARGETS_FOLDER: This global property can be used to  group  AUTOMOC,  AUTOUIC  and
       AUTORCC targets together in an IDE, e.g.  in MSVS.

       CMAKE_GLOBAL_AUTOGEN_TARGET:  A  global  autogen  target,  that  depends on all AUTOMOC or
       AUTOUIC generated <ORIGIN>_autogen targets in the project, will  be  generated  when  this
       variable is ON.

       AUTOGEN_PARALLEL:  This  target  property  controls  the number of moc or uic processes to
       start in parallel during builds.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOUIC_EXECUTABLE
       AUTOUIC_EXECUTABLE is file path pointing to the uic executable to use for AUTOUIC  enabled
       files.  Setting  this  property  will  make  CMake skip the automatic detection of the uic
       binary as well as the sanity-tests normally run to ensure that the binary is available and
       working as expected.

       Usually  this  property  does  not  need  to  be  set.  Only  consider  this  property  if
       auto-detection of uic can not work – e.g. because you are building the uic binary as  part
       of your project.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOUIC_OPTIONS
       Additional options for uic when using AUTOUIC

       This  property  holds  additional  command  line  options  which  will be used when uic is
       executed during the build via AUTOUIC, i.e. it  is  equivalent  to  the  optional  OPTIONS
       argument of the qt4_wrap_ui() macro.

       By default it is empty.

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

       The options set on the target may be overridden by AUTOUIC_OPTIONS set on the  .ui  source
       file.

       This   property  may  use  “generator  expressions”  with  the  syntax  $<...>.   See  the
       cmake-generator-expressions(7) manual for available expressions.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   EXAMPLE
          # ...
          set_property(TARGET tgt PROPERTY AUTOUIC_OPTIONS "--no-protection")
          # ...

   AUTOUIC_SEARCH_PATHS
       Search path list used by AUTOUIC to find included .ui files.

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

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTORCC
       Should the target be processed with auto-rcc (for Qt projects).

       AUTORCC  is  a  boolean  specifying  whether  CMake  will handle the Qt rcc code generator
       automatically, i.e. without having to use the QT4_ADD_RESOURCES()  or  QT5_ADD_RESOURCES()
       macro.  Currently Qt4 and Qt5 are supported.

       When  this  property  is ON, CMake will handle .qrc files added as target sources at build
       time and invoke rcc accordingly.  This  property  is  initialized  by  the  value  of  the
       CMAKE_AUTORCC variable if it is set when a target is created.

       By  default  AUTORCC  is  processed by a custom command.  If the .qrc file is GENERATED, a
       custom target is used instead.

       When there are multiple .qrc files with the same name,  CMake  will  generate  unspecified
       unique output file names for rcc.  Therefore, if Q_INIT_RESOURCE() or Q_CLEANUP_RESOURCE()
       need to be used, the .qrc file name must be unique.

   Modifiers
       AUTORCC_EXECUTABLE: The rcc executable will be detected automatically, but can  be  forced
       to a certain binary by setting this target property.

       AUTORCC_OPTIONS:  Additional  command line options for rcc can be set via this .qrc source
       file property.

       SKIP_AUTORCC: .qrc files can be excluded from AUTORCC processing by  setting  this  source
       file property.

       SKIP_AUTOGEN: Source files can be excluded from AUTOMOC, AUTOUIC and AUTORCC processing by
       setting this source file property.

       AUTOGEN_SOURCE_GROUP: This global property can be used to group files generated by AUTOMOC
       or AUTORCC together in an IDE, e.g.  in MSVS.

       AUTOGEN_TARGETS_FOLDER:  This  global  property  can be used to group AUTOMOC, AUTOUIC and
       AUTORCC targets together in an IDE, e.g.  in MSVS.

       CMAKE_GLOBAL_AUTORCC_TARGET: A global autorcc target that depends on all  AUTORCC  targets
       in the project will be generated when this variable is ON.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTORCC_EXECUTABLE
       AUTORCC_EXECUTABLE  is file path pointing to the rcc executable to use for AUTORCC enabled
       files. Setting this property will make CMake skip  the  automatic  detection  of  the  rcc
       binary as well as the sanity-tests normally run to ensure that the binary is available and
       working as expected.

       Usually  this  property  does  not  need  to  be  set.  Only  consider  this  property  if
       auto-detection  of rcc can not work – e.g. because you are building the rcc binary as part
       of your project.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTORCC_OPTIONS
       Additional options for rcc when using AUTORCC

       This property holds additional command line  options  which  will  be  used  when  rcc  is
       executed  during  the  build  via  AUTORCC,  i.e. it is equivalent to the optional OPTIONS
       argument of the qt4_add_resources() macro.

       By default it is empty.

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

       The  options set on the target may be overridden by AUTORCC_OPTIONS set on the .qrc source
       file.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   EXAMPLE
          # ...
          set_property(TARGET tgt PROPERTY AUTORCC_OPTIONS "--compress;9")
          # ...

   BINARY_DIR
       This read-only property reports the value of the CMAKE_CURRENT_BINARY_DIR variable in  the
       directory in which the target was defined.

   BUILD_RPATH
       A  semicolon-separated  list  specifying  runtime  path (RPATH) entries to add to binaries
       linked in the build tree (for platforms that support it).  The entries will  not  be  used
       for binaries in the install tree.  See also the INSTALL_RPATH target property.

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

       This property supports generator expressions.

   BUILD_RPATH_USE_ORIGIN
       Whether to use relative paths for the build RPATH.

       This property is initialized by the value of the variable CMAKE_BUILD_RPATH_USE_ORIGIN.

       On platforms that support runtime paths (RPATH)  with  the  $ORIGIN  token,  setting  this
       property  to  TRUE  enables  relative  paths in the build RPATH for executables and shared
       libraries that point to shared libraries in the same build tree.

       Normally the build RPATH of a binary contains absolute paths  to  the  directory  of  each
       shared  library it links to.  The RPATH entries for directories contained within the build
       tree can be made relative to enable relocatable builds and to  help  achieve  reproducible
       builds by omitting the build directory from the build environment.

       This  property  has no effect on platforms that do not support the $ORIGIN token in RPATH,
       or when the CMAKE_SKIP_RPATH variable is set. The runtime path set through the BUILD_RPATH
       target property is also unaffected by this property.

   BUILD_WITH_INSTALL_NAME_DIR
       BUILD_WITH_INSTALL_NAME_DIR  is  a  boolean specifying whether the macOS install_name of a
       target in the build tree uses the directory given by INSTALL_NAME_DIR.  This setting  only
       applies to targets on macOS.

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

       If  this  property  is  not  set  and  policy  CMP0068  is   not   NEW,   the   value   of
       BUILD_WITH_INSTALL_RPATH is used in its place.

   BUILD_WITH_INSTALL_RPATH
       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 relinking before installation.

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

       If policy CMP0068 is not NEW, this property also controls use of INSTALL_NAME_DIR  in  the
       build  tree  on  macOS.  Either way, the BUILD_WITH_INSTALL_NAME_DIR target property takes
       precedence.

   BUNDLE_EXTENSION
       The file extension used to name a BUNDLE, a FRAMEWORK, or a MACOSX_BUNDLE  target  on  the
       macOS and iOS.

       The default value is bundle, framework, or app for the respective target types.

   BUNDLE
       This target is a CFBundle on the macOS.

       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.

   C_EXTENSIONS
       Boolean specifying whether compiler specific extensions are requested.

       This  property  specifies  whether  compiler specific extensions should be used.  For some
       compilers, this results in adding a flag such as -std=gnu11 instead  of  -std=c11  to  the
       compile line.  This property is ON by default. The basic C standard level is controlled by
       the C_STANDARD target property.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   C_STANDARD
       The C standard whose features are requested to build this target.

       This property specifies the C standard whose features are requested to build this  target.
       For  some compilers, this results in adding a flag such as -std=gnu11 to the compile line.
       For compilers that have no notion of a standard level, such as Microsoft Visual C++ before
       2015 Update 3, this has no effect.

       Supported values are 90, 99 and 11.

       If  the  value requested does not result in a compile flag being added for the compiler in
       use, a previous standard flag will be added instead.  This means that using:

          set_property(TARGET tgt PROPERTY C_STANDARD 11)

       with a compiler which does not support -std=gnu11 or an equivalent flag will not result in
       an  error or warning, but will instead add the -std=gnu99 or -std=gnu90 flag if supported.
       This “decay” behavior may be controlled  with  the  C_STANDARD_REQUIRED  target  property.
       Additionally,   the   C_EXTENSIONS   target  property  may  be  used  to  control  whether
       compiler-specific extensions are enabled on a per-target basis.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   C_STANDARD_REQUIRED
       Boolean describing whether the value of C_STANDARD is a requirement.

       If this property is set to ON, then the value of the C_STANDARD target property is treated
       as  a  requirement.   If  this property is OFF or unset, the C_STANDARD target property is
       treated as optional and may “decay” to  a  previous  standard  if  the  requested  is  not
       available.   For compilers that have no notion of a standard level, such as MSVC, this has
       no effect.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   COMMON_LANGUAGE_RUNTIME
       By setting this target property, the target is configured to build with C++/CLI support.

       The Visual  Studio  generator  defines  the  clr  parameter  depending  on  the  value  of
       COMMON_LANGUAGE_RUNTIME:

       • property not set: native C++ (i.e. default)

       • property set but empty: mixed unmanaged/managed C++

       • property set to any non empty value: managed C++

       Supported values: "", "pure", "safe"

       This property is only evaluated Visual Studio Generators for VS 2010 and above.

       To  be  able  to  build  managed  C++ targets with VS 2017 and above the component C++/CLI
       support must be installed, which may not be done by default.

       See also IMPORTED_COMMON_LANGUAGE_RUNTIME

   COMPATIBLE_INTERFACE_BOOL
       Properties which must be compatible with their link interface

       The COMPATIBLE_INTERFACE_BOOL property may contain a list of properties  for  this  target
       which  must  be  consistent  when evaluated as a boolean with the INTERFACE variant of the
       property in 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 depender.

       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 specified in this property must not
       intersect with the set specified in any of the other Compatible Interface Properties.

   COMPATIBLE_INTERFACE_NUMBER_MAX
       Properties whose maximum value from the link interface will be used.

       The COMPATIBLE_INTERFACE_NUMBER_MAX property may contain a list  of  properties  for  this
       target  whose  maximum  value may be read at generate time when evaluated in the INTERFACE
       variant of the property in 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 will be compared with each other and with the FOO property in  the  depender.
       When reading the FOO property at generate time, the maximum value will be returned. If the
       property is not set, then it is ignored.

       Note that for each dependee, the set of properties specified in  this  property  must  not
       intersect with the set specified in any of the other Compatible Interface Properties.

   COMPATIBLE_INTERFACE_NUMBER_MIN
       Properties whose maximum value from the link interface will be used.

       The  COMPATIBLE_INTERFACE_NUMBER_MIN  property  may  contain a list of properties for this
       target whose minimum value may be read at generate time when evaluated  in  the  INTERFACE
       variant  of  the property 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  will  be compared with each other and with the FOO property in the depender.
       When reading the FOO property at generate time, the minimum value will  be  returned.   If
       the property is not set, then it is ignored.

       Note  that  for  each  dependee, the set of properties specified in this property must not
       intersect with the set specified in any of the other Compatible Interface Properties.

   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 variant of the property
       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 equal with
       each other, and with the FOO property in the depender.  If the property is not  set,  then
       it is ignored.

       Note  that  for  each  dependee, the set of properties specified in this property must not
       intersect with the set specified in any of the other Compatible Interface Properties.

   COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a target’s sources.

       The COMPILE_DEFINITIONS property may be set to a semicolon-separated 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).

       CMake  will automatically drop some definitions that are not supported by the native build
       tool.

       Disclaimer: Most native build tools have poor support for escaping 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.

       Contents  of  COMPILE_DEFINITIONS  may use “generator expressions” with the syntax $<...>.
       See  the  cmake-generator-expressions(7)  manual  for  available  expressions.   See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       The   corresponding   COMPILE_DEFINITIONS_<CONFIG>   property   may   be  set  to  specify
       per-configuration definitions.  Generator  expressions  should  be  preferred  instead  of
       setting the alternative property.

   COMPILE_FEATURES
       Compiler features enabled for this target.

       The  list  of  features  in  this  property  are  a  subset  of the features listed in the
       CMAKE_CXX_COMPILE_FEATURES variable.

       Contents of COMPILE_FEATURES may use “generator expressions” with the syntax $<...>.   See
       the   cmake-generator-expressions(7)   manual   for   available   expressions.    See  the
       cmake-compile-features(7) manual for  information  on  compile  features  and  a  list  of
       supported compilers.

   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.

       This   property   is   deprecated.    Use   the   COMPILE_OPTIONS    property    or    the
       target_compile_options() command instead.

   COMPILE_OPTIONS
       List of options to pass to the compiler.

       This property holds a semicolon-separated list of options specified so far for its target.
       Use the target_compile_options() command to append more options.

       This property is initialized by the COMPILE_OPTIONS directory property when  a  target  is
       created, and is used by the generators to set the options for the compiler.

       Contents  of  COMPILE_OPTIONS may use “generator expressions” with the syntax $<...>.  See
       the  cmake-generator-expressions(7)   manual   for   available   expressions.    See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   COMPILE_PDB_NAME
       Output  name  for  the  MS debug symbol .pdb file generated by the compiler while building
       source files.

       This property specifies the base name for the debug symbols file.  If not set, the default
       is unspecified.

       NOTE:
          The  compiler-generated  program  database files are specified by the /Fd compiler flag
          and are not the same as linker-generated program database files specified by  the  /pdb
          linker flag.  Use the PDB_NAME property to specify the latter.

   COMPILE_PDB_NAME_<CONFIG>
       Per-configuration  output name for the MS debug symbol .pdb file generated by the compiler
       while building source files.

       This is the configuration-specific version of COMPILE_PDB_NAME.

       NOTE:
          The compiler-generated program database files are specified by the  /Fd  compiler  flag
          and  are  not the same as linker-generated program database files specified by the /pdb
          linker flag.  Use the PDB_NAME_<CONFIG> property to specify the latter.

   COMPILE_PDB_OUTPUT_DIRECTORY
       Output directory for the MS debug  symbol  .pdb  file  generated  by  the  compiler  while
       building source files.

       This  property  specifies  the directory into which the MS debug symbols will be placed by
       the   compiler.    This   property    is    initialized    by    the    value    of    the
       CMAKE_COMPILE_PDB_OUTPUT_DIRECTORY variable if it is set when a target is created.

       NOTE:
          The  compiler-generated  program  database files are specified by the /Fd compiler flag
          and are not the same as linker-generated program database files specified by  the  /pdb
          linker flag.  Use the PDB_OUTPUT_DIRECTORY property to specify the latter.

   COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG>
       Per-configuration  output  directory  for  the  MS debug symbol .pdb file generated by the
       compiler while building source files.

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

       NOTE:
          The compiler-generated program database files are specified by the  /Fd  compiler  flag
          and  are  not the same as linker-generated program database files specified by the /pdb
          linker flag.  Use the PDB_OUTPUT_DIRECTORY_<CONFIG> property to specify the latter.

   <CONFIG>_OUTPUT_NAME
       Old per-configuration target file base name.  Use OUTPUT_NAME_<CONFIG> instead.

       This is a configuration-specific version of the OUTPUT_NAME target property.

   <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.

   CROSSCOMPILING_EMULATOR
       Use  the given emulator to run executables created when crosscompiling.  This command will
       be added as a prefix to add_test(), add_custom_command(), and add_custom_target() commands
       for built target system executables.

       If  this property contains a semicolon-separated list, then the first value is the command
       and remaining values are its arguments.

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

   CUDA_PTX_COMPILATION
       Compile CUDA sources to .ptx files instead of .obj files within Object Libraries.

       For example:

          add_library(myptx OBJECT a.cu b.cu)
          set_property(TARGET myptx PROPERTY CUDA_PTX_COMPILATION ON)

   CUDA_SEPARABLE_COMPILATION
       CUDA only: Enables separate compilation of device code

       If set this will enable separable compilation for all CUDA files for the given target.

       For instance:

          set_property(TARGET myexe PROPERTY CUDA_SEPARABLE_COMPILATION ON)

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

   CUDA_RESOLVE_DEVICE_SYMBOLS
       CUDA only: Enables device linking for the specific library target where required.

       If set, this will tell the required compilers to enable  device  linking  on  the  library
       target.  Device  linking  is  an additional link step required by some CUDA compilers when
       CUDA_SEPARABLE_COMPILATION is enabled. Normally device linking is deferred until a  shared
       library  or  executable  is  generated,  allowing for multiple static libraries to resolve
       device symbols at the same time when they are used by a shared library or executable.

       By default static library targets have this property is disabled,  while  shared,  module,
       and executable targets have this property enabled.

       Note that device linking is not supported for Object Libraries.

       For instance:

          set_property(TARGET mystaticlib PROPERTY CUDA_RESOLVE_DEVICE_SYMBOLS ON)

   CUDA_EXTENSIONS
       Boolean specifying whether compiler specific extensions are requested.

       This  property  specifies  whether  compiler specific extensions should be used.  For some
       compilers, this results in adding a flag such as -std=gnu++11 instead of -std=c++11 to the
       compile  line.   This  property  is  ON  by  default. The basic CUDA/C++ standard level is
       controlled by the CUDA_STANDARD target property.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   CUDA_STANDARD
       The CUDA/C++ standard whose features are requested to build this target.

       This property specifies the CUDA/C++ standard whose features are requested to  build  this
       target.   For  some  compilers,  this results in adding a flag such as -std=gnu++11 to the
       compile line.

       Supported values are 98, 11, 14.

       If the value requested does not result in a compile flag being added for the  compiler  in
       use, a previous standard flag will be added instead.  This means that using:

          set_property(TARGET tgt PROPERTY CUDA_STANDARD 11)

       with  a compiler which does not support -std=gnu++11 or an equivalent flag will not result
       in an error or warning, but will instead add the -std=gnu++98  flag  if  supported.   This
       “decay”  behavior  may  be  controlled  with  the  CUDA_STANDARD_REQUIRED target property.
       Additionally,  the  CUDA_EXTENSIONS  target  property  may  be  used  to  control  whether
       compiler-specific extensions are enabled on a per-target basis.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   CUDA_STANDARD_REQUIRED
       Boolean describing whether the value of CUDA_STANDARD is a requirement.

       If  this  property  is  set  to ON, then the value of the CUDA_STANDARD target property is
       treated as a requirement.  If this property is OFF  or  unset,  the  CUDA_STANDARD  target
       property is treated as optional and may “decay” to a previous standard if the requested is
       not available.  For compilers that have no notion of a standard level, such as MSVC,  this
       has no effect.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   CXX_EXTENSIONS
       Boolean specifying whether compiler specific extensions are requested.

       This  property  specifies  whether  compiler specific extensions should be used.  For some
       compilers, this results in adding a flag such as -std=gnu++11 instead of -std=c++11 to the
       compile  line.  This property is ON by default. The basic C++ standard level is controlled
       by the CXX_STANDARD target property.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   CXX_STANDARD
       The C++ standard whose features are requested to build this target.

       This property specifies the C++ standard  whose  features  are  requested  to  build  this
       target.   For  some  compilers,  this results in adding a flag such as -std=gnu++11 to the
       compile line.  For compilers that have no notion of a standard level,  such  as  Microsoft
       Visual C++ before 2015 Update 3, this has no effect.

       Supported values are 98, 11, 14, 17, and 20.

       If  the  value requested does not result in a compile flag being added for the compiler in
       use, a previous standard flag will be added instead.  This means that using:

          set_property(TARGET tgt PROPERTY CXX_STANDARD 11)

       with a compiler which does not support -std=gnu++11 or an equivalent flag will not  result
       in  an  error  or  warning, but will instead add the -std=gnu++98 flag if supported.  This
       “decay” behavior  may  be  controlled  with  the  CXX_STANDARD_REQUIRED  target  property.
       Additionally,   the  CXX_EXTENSIONS  target  property  may  be  used  to  control  whether
       compiler-specific extensions are enabled on a per-target basis.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   CXX_STANDARD_REQUIRED
       Boolean describing whether the value of CXX_STANDARD is a requirement.

       If this property is set to ON, then the value  of  the  CXX_STANDARD  target  property  is
       treated  as  a  requirement.   If  this  property is OFF or unset, the CXX_STANDARD target
       property is treated as optional and may “decay” to a previous standard if the requested is
       not  available.  For compilers that have no notion of a standard level, such as MSVC, this
       has no effect.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   DEBUG_POSTFIX
       See target property <CONFIG>_POSTFIX.

       This property is a special case of the  more-general  <CONFIG>_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.

   DEPLOYMENT_REMOTE_DIRECTORY
       Set   the   WinCE  project  RemoteDirectory  in  DeploymentTool  and  RemoteExecutable  in
       DebuggerTool in .vcproj files generated by the Visual Studio 9 2008  generator.   This  is
       useful when you want to debug on remote WinCE device.  For example:

          set_property(TARGET ${TARGET} PROPERTY
            DEPLOYMENT_REMOTE_DIRECTORY "\\FlashStorage")

       produces:

          <DeploymentTool RemoteDirectory="\FlashStorage" ... />
          <DebuggerTool RemoteExecutable="\FlashStorage\target_file" ... />

   DEPLOYMENT_ADDITIONAL_FILES
       Set  the WinCE project AdditionalFiles in DeploymentTool in .vcproj files generated by the
       Visual Studio 9 2008 generator.  This is useful when you want to  debug  on  remote  WinCE
       device.  Specify additional files that will be copied to the device.  For example:

          set_property(TARGET ${TARGET} PROPERTY
            DEPLOYMENT_ADDITIONAL_FILES "english.lng|local_folder|remote_folder|0"
            "german.lng|local_folder|remote_folder|0")

       produces:

          <DeploymentTool AdditionalFiles="english.lng|local_folder|remote_folder|0;german.lng|local_folder|remote_folder|0" ... />

   DISABLE_PRECOMPILE_HEADERS
       Disables the precompilation of header files specified by PRECOMPILE_HEADERS property.

       If    the    property   is   not   set,   CMake   will   use   the   value   provided   by
       CMAKE_DISABLE_PRECOMPILE_HEADERS.

   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.

       This property is only evaluated for Visual Studio Generators VS 2010 and above.

       Can     be     initialized     for      all      targets      using      the      variable
       CMAKE_DOTNET_TARGET_FRAMEWORK_VERSION.

   EchoString
       A message to be displayed when the target is built.

       A  message  to display on some generators (such as Makefile Generators) when the target is
       built.

   ENABLE_EXPORTS
       Specify whether an executable exports symbols for loadable modules.

       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  executable  with
       the  target_link_libraries()  command.   On all platforms a target-level dependency on the
       executable is created for targets that link to it.  Handling of the executable on the link
       lines of the loadable modules varies by platform:

       • On  Windows-based  systems  (including Cygwin) an “import library” is created along with
         the executable to list the exported  symbols.   Loadable  modules  link  to  the  import
         library to get the symbols.

       • On macOS, loadable modules link to the executable itself using the -bundle_loader flag.

       • On AIX, a linker “import file” is created along with the executable to list the exported
         symbols for import when linking other targets.  Loadable modules link to the import file
         to get the symbols.

       • On  other  platforms,  loadable  modules  are  simply  linked  without  referencing  the
         executable since the dynamic loader will automatically bind symbols when the  module  is
         loaded.

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

   EXCLUDE_FROM_ALL
       Set this target property to a true (or false) value to exclude  (or  include)  the  target
       from the “all” target of the containing directory and its ancestors.  If excluded, running
       e.g. make in the containing directory or its  ancestors  will  not  build  the  target  by
       default.

       If this target property is not set then the target will be included in the “all” target of
       the containing directory.  Furthermore, it will be included in the  “all”  target  of  its
       ancestor directories unless the EXCLUDE_FROM_ALL directory property is set.

       With  EXCLUDE_FROM_ALL  set  to  false or not set at all, the target will be brought up to
       date as part of doing a make install or its equivalent for the CMake generator being used.
       If  a target has EXCLUDE_FROM_ALL set to true, then any attempt to install that target has
       undefined  behavior.   Note  that  such  a  target  can  still  safely  be  listed  in  an
       install(TARGETS)  command  as long as the install components the target belongs to are not
       part of the set of components that anything tries to install.

   EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>
       Per-configuration version of target exclusion from Build Solution.

       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 configurations for which it has a value.

   EXCLUDE_FROM_DEFAULT_BUILD
       Exclude target from Build Solution.

       This property is only used by Visual Studio generators.  When set to TRUE, the target will
       not be built when you press Build Solution.

   EXPORT_NAME
       Exported name for target files.

       This  sets  the name for the IMPORTED target generated by the install(EXPORT) and export()
       commands.  If not set, the logical target name is used by default.

   EXPORT_PROPERTIES
       List additional properties to export for a target.

       This property  contains  a  list  of  property  names  that  should  be  exported  by  the
       install(EXPORT) and export() commands.  By default only a limited number of properties are
       exported. This property can be used to additionally export other properties as well.

       Properties starting with INTERFACE_ or IMPORTED_ are not allowed as they are reserved  for
       internal CMake use.

       Properties containing generator expressions are also not allowed.

   FOLDER
       Set the folder name. Use to organize targets in an IDE.

       Targets  with  no  FOLDER  property  will appear as top level entities 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.

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

   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-specific  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 specifies 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.

   FRAMEWORK
       Build SHARED or STATIC library as Framework Bundle on the macOS and iOS.

       If such a library target has this property set to TRUE it will be  built  as  a  framework
       when  built  on  the  macOS  and iOS.  It will have the directory structure required for a
       framework and will be suitable to be used with the -framework option.   This  property  is
       initialized  by  the  value  of the CMAKE_FRAMEWORK variable if it is set when a target is
       created.

       To customize Info.plist file in  the  framework,  use  MACOSX_FRAMEWORK_INFO_PLIST  target
       property.

       For macOS see also the FRAMEWORK_VERSION target property.

       Example of creation dynamicFramework:

          add_library(dynamicFramework SHARED
                      dynamicFramework.c
                      dynamicFramework.h
          )
          set_target_properties(dynamicFramework PROPERTIES
            FRAMEWORK TRUE
            FRAMEWORK_VERSION C
            MACOSX_FRAMEWORK_IDENTIFIER com.cmake.dynamicFramework
            MACOSX_FRAMEWORK_INFO_PLIST Info.plist
            # "current version" in semantic format in Mach-O binary file
            VERSION 16.4.0
            # "compatibility version" in semantic format in Mach-O binary file
            SOVERSION 1.0.0
            PUBLIC_HEADER dynamicFramework.h
            XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY "iPhone Developer"
          )

   FRAMEWORK_VERSION
       Version of a framework created using the FRAMEWORK target property (e.g. A).

       This property only affects macOS, as iOS doesn’t have versioned directory structure.

   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().

   GHS_INTEGRITY_APP
       ON  /  OFF  boolean to determine if an executable target should be treated as an Integrity
       Application.

       If no value is set and if a .int file is added as a source file to the  executable  target
       it will be treated as an Integrity Application.

       Supported on Green Hills MULTI.

   GHS_NO_SOURCE_GROUP_FILE
       ON  / OFF boolean to control if the project file for a target should be one single file or
       multiple files.

       The default behavior or when the property is OFF is to generate a  project  file  for  the
       target and then a sub-project file for each source group.

       When  this  property  is  ON or if CMAKE_GHS_NO_SOURCE_GROUP_FILE is ON then only a single
       project file is generated for the target.

       Supported on Green Hills MULTI.

   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.

   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
       literal).  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_COMMON_LANGUAGE_RUNTIME
       Property to define if the target uses C++/CLI.

       Ignored for non-imported targets.

       See also the COMMON_LANGUAGE_RUNTIME target property.

   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> property.  Ignored for non-imported targets.

   IMPORTED_GLOBAL
       Indication of whether an IMPORTED target is globally visible.

       The  boolean  value  of this property is True for targets created with the IMPORTED GLOBAL
       options to add_executable() or add_library(). It is always False for targets built  within
       the project.

       For  targets  created  with  the  IMPORTED option to add_executable() or add_library() but
       without the additional option GLOBAL this is False, too. However,  setting  this  property
       for  such  a  locally  IMPORTED  target to True promotes that target to global scope. This
       promotion can only be done in the same directory where that IMPORTED target was created in
       the first place.

       Once  an  imported  target  has been made global, it cannot be changed back to non-global.
       Therefore, if a project sets this property, it may only provide a  value  of  True.  CMake
       will  issue an error if the project tries to set the property to a non-True value, even if
       the value was already False.

   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_IMPLIB
       Full path to the import library for an IMPORTED target.

       Set  this to the location of the .lib part of a Windows DLL, or on AIX set it to an import
       file created for executables that export symbols (see the ENABLE_EXPORTS target property).
       Ignored for non-imported targets.

   IMPORTED_LIBNAME_<CONFIG>
       <CONFIG>-specific version of IMPORTED_LIBNAME property.

       Configuration  names  correspond to those provided by the project from which the target is
       imported.

   IMPORTED_LIBNAME
       Specify the link library name for an imported Interface Library.

       An interface library builds no library file itself but does specify usage requirements for
       its  consumers.  The IMPORTED_LIBNAME property may be set to specify a single library name
       to be placed on the link line  in  place  of  the  interface  library  target  name  as  a
       requirement for using the interface.

       This property is intended for use in naming libraries provided by a platform SDK for which
       the full path to a library file may not be known.  The value may be a plain  library  name
       such as foo but may not be a path (e.g. /usr/lib/libfoo.so) or a flag (e.g. -Wl,...).  The
       name is never treated as a library target name even if it happens to name one.

       The IMPORTED_LIBNAME property is allowed only  on  imported  Interface  Libraries  and  is
       rejected on targets of other types (for which the IMPORTED_LOCATION target property may be
       used).

   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 completely overrides the generic property for the named
       configuration.

   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 including 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 INTERFACE_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_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 completely overrides the generic property for the named
       configuration.

   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_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 completely overrides the generic property for  the  named
       configuration.

       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
       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_MULTIPLICITY_<CONFIG>
       <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_MULTIPLICITY.

       If   set,   this  property  completely  overrides  the  generic  property  for  the  named
       configuration.

   IMPORTED_LINK_INTERFACE_MULTIPLICITY
       Repetition count for cycles of IMPORTED static libraries.

       This is LINK_INTERFACE_MULTIPLICITY for IMPORTED targets.

   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_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  macOS  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 macOS
       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.

       The IMPORTED_LOCATION target property may be overridden for a given configuration <CONFIG>
       by  the  configuration-specific  IMPORTED_LOCATION_<CONFIG> target property.  Furthermore,
       the MAP_IMPORTED_CONFIG_<CONFIG> target property may be used to map  between  a  project’s
       configurations  and those of an imported target.  If none of these is set then the name of
       any other configuration listed in  the  IMPORTED_CONFIGURATIONS  target  property  may  be
       selected and its IMPORTED_LOCATION_<CONFIG> value used.

       To  get  the  location of an imported target read one of the LOCATION or LOCATION_<CONFIG>
       properties.

       For platforms with import libraries (e.g. Windows) see also IMPORTED_IMPLIB.

   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_NO_SONAME
       Specifies that an IMPORTED shared library target has no soname.

       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_OBJECTS_<CONFIG>
       <CONFIG>-specific version of IMPORTED_OBJECTS property.

       Configuration names correspond to those provided by the project from which the  target  is
       imported.

   IMPORTED_OBJECTS
       A  semicolon-separated  list of absolute paths to the object files on disk for an imported
       object library.

       Ignored for non-imported targets.

       Projects   may   skip   IMPORTED_OBJECTS   if    the    configuration-specific    property
       IMPORTED_OBJECTS_<CONFIG> is set instead.

   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_SONAME_<CONFIG>
       <CONFIG>-specific version of IMPORTED_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.

   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
       target_include_directories()  command.  In addition to accepting values from that command,
       values may be set directly on any target using the set_property() command.  A target  gets
       its  initial  value  for this property from the value of the INCLUDE_DIRECTORIES directory
       property.  Both directory and  target  property  values  are  adjusted  by  calls  to  the
       include_directories() command.

       The  value  of  this  property  is used by the generators to set the include paths for the
       compiler.

       Relative paths should not be added to this property directly.  Use  one  of  the  commands
       above instead to handle relative paths.

       Contents  of  INCLUDE_DIRECTORIES  may  use cmake-generator-expressions(7) with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   INSTALL_NAME_DIR
       macOS directory name for installed targets.

       INSTALL_NAME_DIR  is a string specifying the directory portion of the “install_name” field
       of shared libraries on macOS to use in the installed targets.

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

   INSTALL_REMOVE_ENVIRONMENT_RPATH
       Controls whether toolchain-defined rpaths should be removed during installation.

       When  a  target is being installed, CMake may need to rewrite its rpath information.  This
       occurs when the install rpath (as specified by  the  INSTALL_RPATH  target  property)  has
       different  contents  to  the rpath that the target was built with.  Some toolchains insert
       their own rpath contents into the binary as part of the build.   By  default,  CMake  will
       preserve  those  extra  inserted contents in the install rpath.  For those scenarios where
       such  toolchain-inserted  entries  need  to  be  discarded   during   install,   set   the
       INSTALL_REMOVE_ENVIRONMENT_RPATH target property to true.

       This  property  is initialized by the value of CMAKE_INSTALL_REMOVE_ENVIRONMENT_RPATH when
       the target is created.

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

       This property supports generator expressions.

   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_AUTOUIC_OPTIONS
       List of interface options to pass to uic.

       Targets  may  populate  this property to publish the options required to use when invoking
       uic.  Consuming targets can add entries to their  own  AUTOUIC_OPTIONS  property  such  as
       $<TARGET_PROPERTY:foo,INTERFACE_AUTOUIC_OPTIONS>  to  use the uic options specified in the
       interface of foo. This is done automatically by the target_link_libraries() command.

       This property supports  generator  expressions.   See  the  cmake-generator-expressions(7)
       manual for available expressions.

   INTERFACE_COMPILE_DEFINITIONS
       List of public compile definitions requirements for a library.

       Targets  may populate this property to publish the compile definitions required to compile
       against the headers for the target.  The  target_compile_definitions()  command  populates
       this  property  with values given to the PUBLIC and INTERFACE keywords.  Projects may also
       get and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents  of INTERFACE_COMPILE_DEFINITIONS may use “generator expressions” with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

   INTERFACE_COMPILE_FEATURES
       List of public compile features requirements for a library.

       Targets  may  populate  this  property to publish the compile features required to compile
       against the headers for the target.  The target_compile_features() command populates  this
       property  with  values  given to the PUBLIC and INTERFACE keywords.  Projects may also get
       and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents  of  INTERFACE_COMPILE_FEATURES  may  use “generator expressions” with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

   INTERFACE_COMPILE_OPTIONS
       List of public compile options requirements for a library.

       Targets may populate this property to publish the  compile  options  required  to  compile
       against  the  headers for the target.  The target_compile_options() command populates this
       property with values given to the PUBLIC and INTERFACE keywords.  Projects  may  also  get
       and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents of INTERFACE_COMPILE_OPTIONS may use  “generator  expressions”  with  the  syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

   INTERFACE_INCLUDE_DIRECTORIES
       List of public include directories requirements for a library.

       Targets may populate this property to publish the include directories required to  compile
       against  the  headers  for the target.  The target_include_directories() command populates
       this property with values given to the PUBLIC and INTERFACE keywords.  Projects  may  also
       get and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents of INTERFACE_INCLUDE_DIRECTORIES may use “generator expressions” with the  syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

       Include directories usage requirements commonly differ  between  the  build-tree  and  the
       install-tree.  The BUILD_INTERFACE and INSTALL_INTERFACE generator expressions can be used
       to describe separate usage requirements based on the usage location.  Relative  paths  are
       allowed  within  the  INSTALL_INTERFACE  expression  and  are  interpreted relative to the
       installation prefix.  For example:

          target_include_directories(mylib INTERFACE
            $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include/mylib>
            $<INSTALL_INTERFACE:include/mylib>  # <prefix>/include/mylib
          )

   Creating Relocatable Packages
       Note  that  it   is   not   advisable   to   populate   the   INSTALL_INTERFACE   of   the
       INTERFACE_INCLUDE_DIRECTORIES  of  a target with absolute paths to the include directories
       of dependencies.  That would hard-code into installed packages the include directory paths
       for dependencies as found on the machine the package was made on.

       The INSTALL_INTERFACE of the INTERFACE_INCLUDE_DIRECTORIES is only suitable for specifying
       the required include directories for headers provided with the target  itself,  not  those
       provided  by  the  transitive  dependencies  listed in its INTERFACE_LINK_LIBRARIES target
       property.  Those dependencies should themselves be targets that specify their  own  header
       locations in INTERFACE_INCLUDE_DIRECTORIES.

       See  the  Creating  Relocatable  Packages  section  of  the  cmake-packages(7)  manual for
       discussion of additional care that must be taken when specifying usage requirements  while
       creating packages for redistribution.

   INTERFACE_LINK_DEPENDS
       Additional public interface files on which a target binary depends for linking.

       This  property  is  supported  only  by  Ninja and Makefile Generators.  It is intended to
       specify dependencies on “linker scripts” for custom Makefile link rules.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents of INTERFACE_LINK_DEPENDS may use “generator expressions” with the syntax $<...>.
       See  the  cmake-generator-expressions(7)  manual  for  available  expressions.   See   the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

       Link  dependency  files  usage requirements commonly differ between the build-tree and the
       install-tree.  The BUILD_INTERFACE and INSTALL_INTERFACE generator expressions can be used
       to  describe  separate usage requirements based on the usage location.  Relative paths are
       allowed within the INSTALL_INTERFACE  expression  and  are  interpreted  relative  to  the
       installation prefix.  For example:

          set_property(TARGET mylib PROPERTY INTERFACE_LINK_DEPENDS
            $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/mylinkscript>
            $<INSTALL_INTERFACE:mylinkscript>  # <prefix>/mylinkscript
          )

   INTERFACE_LINK_DIRECTORIES
       List of public link directories requirements for a library.

       Targets  may  populate  this  property to publish the link directories required to compile
       against the headers for the target.  The target_link_directories() command populates  this
       property  with  values  given to the PUBLIC and INTERFACE keywords.  Projects may also get
       and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents  of  INTERFACE_LINK_DIRECTORIES  may  use “generator expressions” with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

   INTERFACE_LINK_LIBRARIES
       List public interface libraries for a library.

       This  property  contains  the  list  of  transitive link dependencies.  When the target is
       linked into another target using the target_link_libraries() command, the libraries listed
       (and  recursively  their  link  interface  libraries) will be provided to the other target
       also.    This   property   is    overridden    by    the    LINK_INTERFACE_LIBRARIES    or
       LINK_INTERFACE_LIBRARIES_<CONFIG> property if policy CMP0022 is OLD or unset.

       Contents  of  INTERFACE_LINK_LIBRARIES  may  use  “generator  expressions” with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       NOTE:
          A call to target_link_libraries(<target> ...) may update this property on <target>.  If
          <target> was not created in the same directory as the call then target_link_libraries()
          will  add  a  suffix  of  the  form ::@<directory-id> to each entry, where the ::@ is a
          separator and the <directory-id> is unspecified.  This tells the  generators  that  the
          named  libraries  must be looked up in the scope of the caller rather than in the scope
          in which the <target> was created.  Valid directory ids are stripped on export  by  the
          install(EXPORT) and export() commands.

   Creating Relocatable Packages
       Note  that  it  is not advisable to populate the INTERFACE_LINK_LIBRARIES of a target with
       absolute paths to dependencies.  That would hard-code into installed packages the  library
       file paths for dependencies as found on the machine the package was made on.

       See  the  Creating  Relocatable  Packages  section  of  the  cmake-packages(7)  manual for
       discussion of additional care that must be taken when specifying usage requirements  while
       creating packages for redistribution.

   INTERFACE_LINK_OPTIONS
       List of public link options requirements for a library.

       Targets may populate this property to publish the link options required to compile against
       the headers for the target.  The target_link_options()  command  populates  this  property
       with values given to the PUBLIC and INTERFACE keywords.  Projects may also get and set the
       property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents of INTERFACE_LINK_OPTIONS may use “generator expressions” with the syntax $<...>.
       See  the  cmake-generator-expressions(7)  manual  for  available  expressions.   See   the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

   INTERFACE_PRECOMPILE_HEADERS
       List of interface header files to precompile into consuming targets.

       Targets  may  populate  this property to publish the header files for consuming targets to
       precompile.  The target_precompile_headers() command populates this property  with  values
       given  to  the  PUBLIC and INTERFACE keywords.  Projects may also get and set the property
       directly.  See the discussion in target_precompile_headers() for guidance  on  appropriate
       use of this property for installed or exported targets.

       Contents  of  INTERFACE_PRECOMPILE_HEADERS may use “generator expressions” with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   INTERFACE_POSITION_INDEPENDENT_CODE
       Whether consumers need to create a position-independent target

       The  INTERFACE_POSITION_INDEPENDENT_CODE property informs consumers of this target whether
       they must set their POSITION_INDEPENDENT_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 consumers 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
       INTERFACE_POSITION_INDEPENDENT_CODE property.

       Contents of INTERFACE_POSITION_INDEPENDENT_CODE may use “generator expressions”  with  the
       syntax  $<...>.   See the cmake-generator-expressions(7) manual for available expressions.
       See the cmake-buildsystem(7) manual for more on defining buildsystem properties.

   INTERFACE_SOURCES
       List of interface sources to compile into consuming targets.

       Targets may populate this property  to  publish  the  sources  for  consuming  targets  to
       compile.   The  target_sources()  command populates this property with values given to the
       PUBLIC and INTERFACE keywords.  Projects may also get and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the sources of the consumer.

       Contents of INTERFACE_SOURCES may use “generator expressions” with the syntax $<...>.  See
       the  cmake-generator-expressions(7)   manual   for   available   expressions.    See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   INTERFACE_SYSTEM_INCLUDE_DIRECTORIES
       List of public system include directories for a library.

       Targets may populate this property to publish the include directories which contain system
       headers,   and   therefore   should   not    result    in    compiler    warnings.     The
       target_include_directories(SYSTEM)  command  signature populates this property with values
       given to the PUBLIC and INTERFACE keywords.

       Projects may also get and set the  property  directly,  but  must  be  aware  that  adding
       directories  to  this  property  does  not make those directories used during compilation.
       Adding directories to this property marks directories as SYSTEM which otherwise  would  be
       used  in  a  non-SYSTEM  manner.   This can appear similar to ‘duplication’, so prefer the
       high-level target_include_directories(SYSTEM) command and avoid setting  the  property  by
       low-level means.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to mark the same include directories  as  containing
       system headers.

       Contents  of INTERFACE_SYSTEM_INCLUDE_DIRECTORIES may use “generator expressions” with the
       syntax $<...>.  See the cmake-generator-expressions(7) manual for  available  expressions.
       See the cmake-buildsystem(7) manual for more on defining buildsystem properties.

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

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

       This property is initialized by the  CMAKE_INTERPROCEDURAL_OPTIMIZATION_<CONFIG>  variable
       if it is set when a target is created.

   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. Depending on value of policy CMP0069, the error will be reported or ignored,
       if interprocedural optimization is enabled but not supported.

       This  property  is initialized by the CMAKE_INTERPROCEDURAL_OPTIMIZATION variable if it is
       set when a target is created.

   IOS_INSTALL_COMBINED
       Build a combined (device and simulator) target when installing.

       When this property is set to set to false (which is the default) then it  will  either  be
       built  with  the  device  SDK  or  the simulator SDK depending on the SDK set. But if this
       property is set to true then the target will  at  install  time  also  be  built  for  the
       corresponding SDK and combined into one library.

       This feature requires at least Xcode version 6.

   JOB_POOL_COMPILE
       Ninja only: Pool used for compiling.

       The  number  of  parallel  compile  processes  could be limited by defining pools with the
       global JOB_POOLS property and then specifying here the pool name.

       For instance:

          set_property(TARGET myexe PROPERTY JOB_POOL_COMPILE ten_jobs)

       This property is initialized by the value of CMAKE_JOB_POOL_COMPILE.

   JOB_POOL_LINK
       Ninja only: Pool used for linking.

       The number of parallel link processes could be limited by defining pools with  the  global
       JOB_POOLS property and then specifying here the pool name.

       For instance:

          set_property(TARGET myexe PROPERTY JOB_POOL_LINK two_jobs)

       This property is initialized by the value of CMAKE_JOB_POOL_LINK.

   LABELS
       Specify a list of text labels associated with a target.

       Target label semantics are currently unspecified.

   <LANG>_CLANG_TIDY
       This property is implemented only when <LANG> is C or CXX.

       Specify a semicolon-separated list containing a command line for the clang-tidy tool.  The
       Makefile Generators and the Ninja generator will run this tool along with the compiler and
       report a warning if the tool reports any problems.

       This property is initialized by the value of the CMAKE_<LANG>_CLANG_TIDY variable if it is
       set when a target is created.

   <LANG>_COMPILER_LAUNCHER
       This property is implemented only when <LANG> is C, CXX, Fortran, OBJC, OBJCXX, or CUDA.

       Specify a semicolon-separated list containing a command  line  for  a  compiler  launching
       tool.  The  Makefile  Generators  and  the Ninja generator will run this tool and pass the
       compiler and its arguments to the tool. Some example tools are distcc and ccache.

       This property is initialized by the value of the  CMAKE_<LANG>_COMPILER_LAUNCHER  variable
       if it is set when a target is created.

   <LANG>_CPPCHECK
       This property is supported only when <LANG> is C or CXX.

       Specify  a  semicolon-separated  list  containing  a  command line for the cppcheck static
       analysis tool.  The Makefile Generators and the Ninja generator will  run  cppcheck  along
       with  the  compiler  and report any problems.  If the command-line specifies the exit code
       options to cppcheck then the build  will fail if the tool returns non-zero.

       This property is initialized by the value of the CMAKE_<LANG>_CPPCHECK variable if  it  is
       set when a target is created.

   <LANG>_CPPLINT
       This property is supported only when <LANG> is C or CXX.

       Specify  a  semicolon-separated  list  containing  a  command  line  for the cpplint style
       checker.  The Makefile Generators and the Ninja generator will run cpplint along with  the
       compiler and report any problems.

       This  property  is  initialized by the value of the CMAKE_<LANG>_CPPLINT variable if it is
       set when a target is created.

   <LANG>_INCLUDE_WHAT_YOU_USE
       This property is implemented only when <LANG> is C or CXX.

       Specify a semicolon-separated list containing a command line for the  include-what-you-use
       tool.   The  Makefile Generators and the Ninja generator will run this tool along with the
       compiler and report a warning if the tool reports any problems.

       This property  is  initialized  by  the  value  of  the  CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE
       variable if it is set when a target is created.

   <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 -fvisibility= for <LANG>.  This property  affects  compilation  in
       sources of all types of targets (subject to policy CMP0063).

       This  property  is initialized by the value of the CMAKE_<LANG>_VISIBILITY_PRESET variable
       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 the LIBRARY_OUTPUT_DIRECTORY target  property,  but
       multi-configuration   generators  (Visual  Studio  Generators,  Xcode)  do  NOT  append  a
       per-configuration subdirectory to the specified directory.  This property  is  initialized
       by  the  value of the CMAKE_LIBRARY_OUTPUT_DIRECTORY_<CONFIG> variable if it is set when a
       target is created.

       Contents of LIBRARY_OUTPUT_DIRECTORY_<CONFIG> may use generator expressions.

   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.
       The  property  value  may  use generator expressions.  Multi-configuration generators (VS,
       Xcode) append a  per-configuration  subdirectory  to  the  specified  directory  unless  a
       generator expression is used.

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

       See also the LIBRARY_OUTPUT_DIRECTORY_<CONFIG> target property.

   LIBRARY_OUTPUT_NAME_<CONFIG>
       Per-configuration output name for LIBRARY target files.

       This is the configuration-specific version of the LIBRARY_OUTPUT_NAME target property.

   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.

       See also the LIBRARY_OUTPUT_NAME_<CONFIG> target property.

   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 dependencies 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 created.

   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 supported only by Ninja and  Makefile  Generators.   It  is  intended  to
       specify dependencies on “linker scripts” for custom Makefile link rules.

       Contents  of LINK_DEPENDS may use “generator expressions” with the syntax $<...>.  See the
       cmake-generator-expressions(7)   manual    for    available    expressions.     See    the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   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_PREFERENCE variables.

       If this property is not set by the user, it will be calculated at generate-time by CMake.

   LINK_DIRECTORIES
       List  of  directories  to  use  for the link step of shared library, module and executable
       targets.

       This property holds a semicolon-separated list of directories specified  so  far  for  its
       target.  Use the target_link_directories() command to append more search directories.

       This  property  is initialized by the LINK_DIRECTORIES directory property when a target is
       created, and is used by the generators to set the search directories for the linker.

       Contents of LINK_DIRECTORIES may use “generator expressions” with the syntax $<...>.   See
       the   cmake-generator-expressions(7)   manual   for   available   expressions.    See  the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   LINK_FLAGS_<CONFIG>
       Per-configuration linker flags for a SHARED library, MODULE or EXECUTABLE target.

       This is the configuration-specific version of LINK_FLAGS.

       NOTE:
          This property has been superseded by LINK_OPTIONS property.

   LINK_FLAGS
       Additional flags to use when linking this  target  if  it  is  a  shared  library,  module
       library,  or  an  executable.  Static  libraries  need  to  use  STATIC_LIBRARY_OPTIONS or
       STATIC_LIBRARY_FLAGS properties.

       The LINK_FLAGS property, managed as a string, can be used to add extra flags to  the  link
       step  of  a  target.   LINK_FLAGS_<CONFIG>  will  add  to  the configuration <CONFIG>, for
       example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO, …

       NOTE:
          This property has been superseded by LINK_OPTIONS property.

   LINK_INTERFACE_LIBRARIES_<CONFIG>
       Per-configuration list of public interface libraries for a target.

       This is the configuration-specific version  of  LINK_INTERFACE_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.

   Creating Relocatable Packages
       Note that it is not advisable  to  populate  the  LINK_INTERFACE_LIBRARIES_<CONFIG>  of  a
       target  with absolute paths to dependencies.  That would hard-code into installed packages
       the library file paths for dependencies as found on the machine the package was made on.

       See the  Creating  Relocatable  Packages  section  of  the  cmake-packages(7)  manual  for
       discussion  of additional care that must be taken when specifying usage requirements while
       creating packages for redistribution.

   LINK_INTERFACE_LIBRARIES
       List public interface libraries for a shared library or executable.

       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 target
       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 using the target_link_libraries() command, 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 CMAKE_LINK_INTERFACE_LIBRARIES variable 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.

   Creating Relocatable Packages
       Note that it is not advisable to populate the LINK_INTERFACE_LIBRARIES of  a  target  with
       absolute  paths to dependencies.  That would hard-code into installed packages the library
       file paths for dependencies as found on the machine the package was made on.

       See the  Creating  Relocatable  Packages  section  of  the  cmake-packages(7)  manual  for
       discussion  of additional care that must be taken when specifying usage requirements while
       creating packages for redistribution.

   LINK_INTERFACE_MULTIPLICITY_<CONFIG>
       Per-configuration repetition count for cycles of STATIC libraries.

       This is the configuration-specific version of LINK_INTERFACE_MULTIPLICITY.  If  set,  this
       property completely overrides the generic property for the named configuration.

   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_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 value of this property is used by the generators to set the  link  libraries  for  the
       compiler.

       Contents  of  LINK_LIBRARIES  may use “generator expressions” with the syntax $<...>.  See
       the  cmake-generator-expressions(7)   manual   for   available   expressions.    See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       NOTE:
          A call to target_link_libraries(<target> ...) may update this property on <target>.  If
          <target> was not created in the same directory as the call then target_link_libraries()
          will  add  a  suffix  of  the  form ::@<directory-id> to each entry, where the ::@ is a
          separator and the <directory-id> is unspecified.  This tells the  generators  that  the
          named  libraries  must be looked up in the scope of the caller rather than in the scope
          in which the <target> was created.  Valid directory ids are stripped on export  by  the
          install(EXPORT) and export() commands.

   LINK_OPTIONS
       List of options to use for the link step of shared library, module and executable targets.
       Targets that are static libraries need to use the STATIC_LIBRARY_OPTIONS target property.

       This property holds a semicolon-separated list of options specified so far for its target.
       Use the target_link_options() command to append more options.

       This  property  is  initialized  by  the  LINK_OPTIONS directory property when a target is
       created, and is used by the generators to set the options for the compiler.

       Contents of LINK_OPTIONS may use “generator expressions” with the syntax $<...>.  See  the
       cmake-generator-expressions(7)    manual    for    available    expressions.     See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       NOTE:
          This property must be used in preference to LINK_FLAGS property.

   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.

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

       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).

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

       See also LINK_SEARCH_END_STATIC.

   LINK_WHAT_YOU_USE
       This is a boolean option that when set to TRUE will automatically run ldd  -r  -u  on  the
       target  after it is linked. In addition, the linker flag -Wl,--no-as-needed will be passed
       to the target with the link command so that all libraries specified on  the  command  line
       will be linked into the target. This will result in the link producing a list of libraries
       that provide no symbols used by this target but are being linked  to  it.   This  is  only
       applicable  to  executable  and  shared library targets and will only work when ld and ldd
       accept the flags used.

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

   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  configuration.  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)(_<CONFIG>)?,  (IMPLIB_)?(PREFIX|SUFFIX),
       or  LINKER_LANGUAGE.  Failure to follow this rule is not diagnosed and leaves the location
       of the target undefined.

   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 configuration <CONFIG> provided by the target.

       For  a non-imported target, this property is provided for compatibility with CMake 2.4 and
       below.  It was meant to get the location of an executable target’s output file for use  in
       add_custom_command().   The  path  may  contain  a  build-system-specific  portion that is
       replaced at build time with the configuration getting 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()  recognizes  generator  expressions  to  refer  to target
       locations anywhere 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)(_<CONFIG>)?,  (IMPLIB_)?(PREFIX|SUFFIX),
       or “LINKER_LANGUAGE”.  Failure to follow  this  rule  is  not  diagnosed  and  leaves  the
       location of the target undefined.

   MACOSX_BUNDLE_INFO_PLIST
       Specify a custom Info.plist template for a macOS and iOS Application Bundle.

       An  executable target with MACOSX_BUNDLE enabled will be built as an application bundle on
       macOS.  By default its Info.plist  file  is  created  by  configuring  a  template  called
       MacOSXBundleInfo.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_BUNDLE_NAME
              Sets CFBundleName.

       MACOSX_BUNDLE_BUNDLE_VERSION
              Sets CFBundleVersion.

       MACOSX_BUNDLE_COPYRIGHT
              Sets NSHumanReadableCopyright.

       MACOSX_BUNDLE_GUI_IDENTIFIER
              Sets CFBundleIdentifier.

       MACOSX_BUNDLE_ICON_FILE
              Sets CFBundleIconFile.

       MACOSX_BUNDLE_INFO_STRING
              Sets CFBundleGetInfoString.

       MACOSX_BUNDLE_LONG_VERSION_STRING
              Sets CFBundleLongVersionString.

       MACOSX_BUNDLE_SHORT_VERSION_STRING
              Sets CFBundleShortVersionString.

       CMake  variables  of the same name may be set to affect all targets 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_BUNDLE
       Build an executable as an Application Bundle on macOS or iOS.

       When  this  property  is  set  to  TRUE  the executable when built on macOS or iOS 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 bundle.  This property is  initialized
       by the value of the variable CMAKE_MACOSX_BUNDLE if it is set when a target is created.

   MACOSX_FRAMEWORK_INFO_PLIST
       Specify a custom Info.plist template for a macOS and iOS Framework.

       A library target with FRAMEWORK enabled will be built as a framework on macOS.  By default
       its    Info.plist    file    is    created    by    configuring    a    template    called
       MacOSXFrameworkInfo.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_BUNDLE_VERSION
              Sets CFBundleVersion.

       MACOSX_FRAMEWORK_ICON_FILE
              Sets CFBundleIconFile.

       MACOSX_FRAMEWORK_IDENTIFIER
              Sets CFBundleIdentifier.

       MACOSX_FRAMEWORK_SHORT_VERSION_STRING
              Sets CFBundleShortVersionString.

       CMake  variables  of the same name may be set to affect all targets 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 this target on macOS or iOS is located at runtime using rpaths.

       When this property is set to TRUE, the directory portion of the install_name field of this
       shared library will be @rpath unless overridden by INSTALL_NAME_DIR.  This  indicates  the
       shared library is to be found at runtime using runtime paths (rpaths).

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

       Runtime paths will also be embedded in binaries using this target and can be controlled by
       the INSTALL_RPATH target property on the target linking to this target.

       Policy  CMP0042  was introduced to change the default value of MACOSX_RPATH to TRUE.  This
       is because use of @rpath is a more flexible and powerful alternative  to  @executable_path
       and @loader_path.

   MANUALLY_ADDED_DEPENDENCIES
       Get manually added dependencies to other top-level targets.

       This  read-only  property  can  be used to query all dependencies that were added for this
       target with the add_dependencies() command.

   MAP_IMPORTED_CONFIG_<CONFIG>
       Map from project configuration to imported target’s configuration.

       Set this to the list of configurations of an imported target that  may  be  used  for  the
       current  project’s  <CONFIG> configuration.  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 configurations are suitable for use when building
       the <CONFIG> configuration.  The first configuration in the list found to be  provided  by
       the  imported  target  (i.e. via IMPORTED_LOCATION_<CONFIG> for the mapped-to <CONFIG>) is
       selected.  As a special case, an empty  list  element  refers  to  the  configuration-less
       imported target location (i.e. IMPORTED_LOCATION).

       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.

       This property is  initialized  by  the  value  of  the  CMAKE_MAP_IMPORTED_CONFIG_<CONFIG>
       variable if it is set when a target is created.

   Example
       For example creating imported C++ library foo:

          add_library(foo STATIC IMPORTED)

       Use foo_debug path for Debug build type:

          set_property(
            TARGET foo APPEND PROPERTY IMPORTED_CONFIGURATIONS DEBUG
            )

          set_target_properties(foo PROPERTIES
            IMPORTED_LINK_INTERFACE_LANGUAGES_DEBUG "CXX"
            IMPORTED_LOCATION_DEBUG "${foo_debug}"
            )

       Use foo_release path for Release build type:

          set_property(
            TARGET foo APPEND PROPERTY IMPORTED_CONFIGURATIONS RELEASE
            )

          set_target_properties(foo PROPERTIES
            IMPORTED_LINK_INTERFACE_LANGUAGES_RELEASE "CXX"
            IMPORTED_LOCATION_RELEASE "${foo_release}"
            )

       Use Release version of library for MinSizeRel and RelWithDebInfo build types:

          set_target_properties(foo PROPERTIES
            MAP_IMPORTED_CONFIG_MINSIZEREL Release
            MAP_IMPORTED_CONFIG_RELWITHDEBINFO Release
            )

   MSVC_RUNTIME_LIBRARY
       Select the MSVC runtime library for use by compilers targeting the MSVC ABI.

       The allowed values are:

       MultiThreaded
              Compile  with  -MT  or equivalent flag(s) to use a multi-threaded statically-linked
              runtime library.

       MultiThreadedDLL
              Compile with -MD or equivalent flag(s) to use a  multi-threaded  dynamically-linked
              runtime library.

       MultiThreadedDebug
              Compile  with  -MTd or equivalent flag(s) to use a multi-threaded statically-linked
              runtime library.

       MultiThreadedDebugDLL
              Compile with -MDd or equivalent flag(s) to use a multi-threaded  dynamically-linked
              runtime library.

       The value is ignored on non-MSVC compilers but an unsupported value will be rejected as an
       error when using a compiler targeting the MSVC ABI.

       The value may also be the empty string ("") in which case  no  runtime  library  selection
       flag  will  be  added  explicitly  by  CMake.  Note that with Visual Studio Generators the
       native build system may choose to add its own default runtime library selection flag.

       Use generator expressions to support per-configuration specification.   For  example,  the
       code:

          add_executable(foo foo.c)
          set_property(TARGET foo PROPERTY
            MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Debug>:Debug>")

       selects  for  the  target  foo  a multi-threaded statically-linked runtime library with or
       without debug information depending on the configuration.

       If   this   property   is   not    set    then    CMake    uses    the    default    value
       MultiThreaded$<$<CONFIG:Debug>:Debug>DLL to select a MSVC runtime library.

       NOTE:
          This  property  has  effect  only  when policy CMP0091 is set to NEW prior to the first
          project() or enable_language()  command  that  enables  a  language  using  a  compiler
          targeting the MSVC ABI.

   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.

       Enable  this  boolean  property  if a generated SHARED library should not have soname set.
       Default is to set soname on all shared libraries as long  as  the  platform  supports  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.  Therefore, once installed, dynamic loader may  eventually  fail  to
       locate the library for the binary.

   NO_SYSTEM_FROM_IMPORTED
       Do  not  treat  include  directories  from  the interfaces of consumed imported targets as
       SYSTEM.

       The contents of the INTERFACE_INCLUDE_DIRECTORIES target property of imported targets  are
       treated  as  SYSTEM  includes  by  default.   If  this  property  is  enabled on a target,
       compilation  of  sources  in  that  target  will   not   treat   the   contents   of   the
       INTERFACE_INCLUDE_DIRECTORIES of consumed imported targets as system includes.

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

   OBJC_EXTENSIONS
       Boolean specifying whether compiler specific extensions are requested.

       This property specifies whether compiler specific extensions should  be  used.   For  some
       compilers,  this  results  in  adding a flag such as -std=gnu11 instead of -std=c11 to the
       compile line.  This property is ON by default. The basic OBJC standard level is controlled
       by the OBJC_STANDARD target property.

       If  the  property  is  not  set,  and  the  project has set the C_EXTENSIONS, the value of
       C_EXTENSIONS is set for OBJC_EXTENSIONS.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   OBJC_STANDARD
       The OBJC standard whose features are requested to build this target.

       This property specifies the OBJC standard whose  features  are  requested  to  build  this
       target.   For  some  compilers,  this  results  in adding a flag such as -std=gnu11 to the
       compile line.

       Supported values are 90, 99 and 11.

       If the value requested does not result in a compile flag being added for the  compiler  in
       use, a previous standard flag will be added instead.  This means that using:

          set_property(TARGET tgt PROPERTY OBJC_STANDARD 11)

       with a compiler which does not support -std=gnu11 or an equivalent flag will not result in
       an error or warning, but will instead add the -std=gnu99 or -std=gnu90 flag if  supported.
       This  “decay”  behavior may be controlled with the OBJC_STANDARD_REQUIRED target property.
       Additionally,  the  OBJC_EXTENSIONS  target  property  may  be  used  to  control  whether
       compiler-specific extensions are enabled on a per-target basis.

       If  the  property  is  not  set,  and  the  project  has  set the C_STANDARD, the value of
       C_STANDARD is set for OBJC_STANDARD.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   OBJC_STANDARD_REQUIRED
       Boolean describing whether the value of OBJC_STANDARD is a requirement.

       If this property is set to ON, then the value of  the  OBJC_STANDARD  target  property  is
       treated  as  a  requirement.   If  this property is OFF or unset, the OBJC_STANDARD target
       property is treated as optional and may “decay” to a previous standard if the requested is
       not available.

       If  the property is not set, and the project has set the C_STANDARD_REQUIRED, the value of
       C_STANDARD_REQUIRED is set for OBJC_STANDARD_REQUIRED.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   OBJCXX_EXTENSIONS
       Boolean specifying whether compiler specific extensions are requested.

       This property specifies whether compiler specific extensions should  be  used.   For  some
       compilers, this results in adding a flag such as -std=gnu++11 instead of -std=c++11 to the
       compile line.  This property is  ON  by  default.  The  basic  ObjC++  standard  level  is
       controlled by the OBJCXX_STANDARD target property.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

       If the property is not set, and the project has  set  the  CXX_EXTENSIONS,  the  value  of
       CXX_EXTENSIONS is set for OBJCXX_EXTENSIONS.

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

   OBJCXX_STANDARD
       The ObjC++ standard whose features are requested to build this target.

       This property specifies the ObjC++ standard whose features are  requested  to  build  this
       target.   For  some  compilers,  this results in adding a flag such as -std=gnu++11 to the
       compile line.

       Supported values are 98, 11, 14, 17, and 20.

       If the value requested does not result in a compile flag being added for the  compiler  in
       use, a previous standard flag will be added instead.  This means that using:

          set_property(TARGET tgt PROPERTY OBJCXX_STANDARD 11)

       with  a compiler which does not support -std=gnu++11 or an equivalent flag will not result
       in an error or warning, but will instead add the -std=gnu++98  flag  if  supported.   This
       “decay”  behavior  may  be  controlled  with the OBJCXX_STANDARD_REQUIRED target property.
       Additionally, the OBJCXX_EXTENSIONS  target  property  may  be  used  to  control  whether
       compiler-specific extensions are enabled on a per-target basis.

       If  the  property  is  not  set,  and  the  project has set the CXX_STANDARD, the value of
       CXX_STANDARD is set for OBJCXX_STANDARD.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   OBJCXX_STANDARD_REQUIRED
       Boolean describing whether the value of OBJCXX_STANDARD is a requirement.

       If this property is set to ON, then the value of the OBJCXX_STANDARD  target  property  is
       treated  as  a  requirement.  If this property is OFF or unset, the OBJCXX_STANDARD target
       property is treated as optional and may “decay” to a previous standard if the requested is
       not available.

       If  the  property is not set, and the project has set the CXX_STANDARD_REQUIRED, the value
       of CXX_STANDARD_REQUIRED is set for OBJCXX_STANDARD_REQUIRED.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

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

   OSX_ARCHITECTURES_<CONFIG>
       Per-configuration macOS and iOS binary architectures for a target.

       This property is the configuration-specific version of OSX_ARCHITECTURES.

   OSX_ARCHITECTURES
       Target specific architectures for macOS.

       The OSX_ARCHITECTURES property sets the target binary architecture for  targets  on  macOS
       (-arch).     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,
       where <CONFIG> is an upper-case name (e.g. OSX_ARCHITECTURES_DEBUG).

   OUTPUT_NAME_<CONFIG>
       Per-configuration target file base name.

       This is the configuration-specific version of the OUTPUT_NAME target property.

   OUTPUT_NAME
       Output name for target files.

       This sets the base name for output files created for an executable or library target.   If
       not  set,  the  logical target name is used by default during generation. The value is not
       set by default during configuration.

       Contents of OUTPUT_NAME and the variants listed below may use generator expressions.

       See also the variants:

       • OUTPUT_NAME_<CONFIG>ARCHIVE_OUTPUT_NAME_<CONFIG>ARCHIVE_OUTPUT_NAMELIBRARY_OUTPUT_NAME_<CONFIG>LIBRARY_OUTPUT_NAMERUNTIME_OUTPUT_NAME_<CONFIG>RUNTIME_OUTPUT_NAME

   PDB_NAME_<CONFIG>
       Per-configuration output name for the MS debug symbol .pdb file generated  by  the  linker
       for an executable or shared library target.

       This is the configuration-specific version of PDB_NAME.

       NOTE:
          This  property does not apply to STATIC library targets because no linker is invoked to
          produce them so they have no linker-generated .pdb file containing debug symbols.

          The linker-generated program database files are specified by the /pdb linker  flag  and
          are  not  the  same  as  compiler-generated program database files specified by the /Fd
          compiler flag.  Use the COMPILE_PDB_NAME_<CONFIG> property to specify the latter.

   PDB_NAME
       Output name for the MS debug symbol .pdb file generated by the linker for an executable or
       shared library target.

       This  property  specifies  the  base  name  for  the  debug symbols file.  If not set, the
       OUTPUT_NAME target property value or logical target name is used by default.

       NOTE:
          This property does not apply to STATIC library targets because no linker is invoked  to
          produce them so they have no linker-generated .pdb file containing debug symbols.

          The  linker-generated  program database files are specified by the /pdb linker flag and
          are not the same as compiler-generated program database  files  specified  by  the  /Fd
          compiler flag.  Use the COMPILE_PDB_NAME property to specify the latter.

   PDB_OUTPUT_DIRECTORY_<CONFIG>
       Per-configuration  output  directory  for  the  MS debug symbol .pdb file generated by the
       linker for an executable or shared library target.

       This is a  per-configuration  version  of  PDB_OUTPUT_DIRECTORY,  but  multi-configuration
       generators   (Visual   Studio   Generators,  Xcode)  do  NOT  append  a  per-configuration
       subdirectory to the specified directory.  This property is initialized by the value of the
       CMAKE_PDB_OUTPUT_DIRECTORY_<CONFIG> variable if it is set when a target is created.

       Contents of PDB_OUTPUT_DIRECTORY_<CONFIG> may use generator expressions.

       NOTE:
          This  property does not apply to STATIC library targets because no linker is invoked to
          produce them so they have no linker-generated .pdb file containing debug symbols.

          The linker-generated program database files are specified by the /pdb linker  flag  and
          are  not  the  same  as  compiler-generated program database files specified by the /Fd
          compiler flag.  Use the COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG> property to  specify  the
          latter.

   PDB_OUTPUT_DIRECTORY
       Output  directory  for  the  MS  debug  symbols  .pdb  file generated by the linker for an
       executable or shared library target.

       This property specifies the directory into which the MS debug symbols will  be  placed  by
       the  linker.  The  property  value  may  use  generator  expressions.  Multi-configuration
       generators append a per-configuration subdirectory to the  specified  directory  unless  a
       generator expression is used.

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

       NOTE:
          This property does not apply to STATIC library targets because no linker is invoked  to
          produce them so they have no linker-generated .pdb file containing debug symbols.

          The  linker-generated  program database files are specified by the /pdb linker flag and
          are not the same as compiler-generated program database  files  specified  by  the  /Fd
          compiler flag.  Use the COMPILE_PDB_OUTPUT_DIRECTORY property to specify the latter.

   POSITION_INDEPENDENT_CODE
       Whether to create a position-independent target

       The POSITION_INDEPENDENT_CODE property determines whether position independent executables
       or shared libraries will be created.  This property is True  by  default  for  SHARED  and
       MODULE  library targets and False otherwise.  This property is initialized by the value of
       the CMAKE_POSITION_INDEPENDENT_CODE variable  if it is set when a target is created.

       NOTE:
          For executable targets, the link step is controlled  by  the  CMP0083  policy  and  the
          CheckPIESupported module.

   PRECOMPILE_HEADERS
       List of header files to precompile.

       This  property holds a semicolon-separated list of header files to precompile specified so
       far for its target.  Use the target_precompile_headers() command  to  append  more  header
       files.

       This property supports generator expressions.

   PRECOMPILE_HEADERS_REUSE_FROM
       Target from which to reuse the precompiled headers build artifact.

       See  the  second  signature  of  target_precompile_headers()  command  for  more  detailed
       information.

   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.

   PRIVATE_HEADER
       Specify private header files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate  frameworks  on  macOS,
       iOS 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 framework folder.  On
       non-Apple  platforms these headers may be installed using the PRIVATE_HEADER option to the
       install(TARGETS) 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 Visual Studio.

   PUBLIC_HEADER
       Specify public header files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate  frameworks  on  macOS,
       iOS 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 or BUNDLE.

       Target marked with the FRAMEWORK or BUNDLE  property  generate  framework  or  application
       bundle  (both  macOS  and iOS is supported) or normal shared libraries on other platforms.
       This property may be set to a list of files to be placed in  the  corresponding  directory
       (eg. Resources directory for macOS) inside the bundle.  On non-Apple platforms these files
       may be installed using the RESOURCE option to the install(TARGETS) command.

       Following example of Application Bundle:

          add_executable(ExecutableTarget
            addDemo.c
            resourcefile.txt
            appresourcedir/appres.txt)

          target_link_libraries(ExecutableTarget heymath mul)

          set(RESOURCE_FILES
            resourcefile.txt

            MACOSX_BUNDLE TRUE
            MACOSX_FRAMEWORK_IDENTIFIER org.cmake.ExecutableTarget
            RESOURCE "${RESOURCE_FILES}")

       will produce flat structure for iOS systems:

          ExecutableTarget.app
            appres.txt
            ExecutableTarget
            Info.plist
            resourcefile.txt

       For macOS systems it will produce following directory structure:

          ExecutableTarget.app/
            Contents
              Info.plist
              MacOS

              Resources
                appres.txt
                resourcefile.txt

       For Linux, such CMake script produce following files:

          ExecutableTarget
          Resources
            appres.txt
            resourcefile.txt

   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_<CONFIG>
       Per-configuration output directory for RUNTIME target files.

       This  is  a per-configuration version of the RUNTIME_OUTPUT_DIRECTORY target property, but
       multi-configuration  generators  (Visual  Studio  Generators,  Xcode)  do  NOT  append   a
       per-configuration  subdirectory  to the specified directory.  This property is initialized
       by the value of the CMAKE_RUNTIME_OUTPUT_DIRECTORY_<CONFIG> variable if it is set  when  a
       target is created.

       Contents of RUNTIME_OUTPUT_DIRECTORY_<CONFIG> may use generator expressions.

   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.
       The property value may use generator  expressions.   Multi-configuration  generators  (VS,
       Xcode)  append  a  per-configuration  subdirectory  to  the  specified  directory unless a
       generator expression is used.

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

       See also the RUNTIME_OUTPUT_DIRECTORY_<CONFIG> target property.

   RUNTIME_OUTPUT_NAME_<CONFIG>
       Per-configuration output name for RUNTIME target files.

       This is the configuration-specific version of the RUNTIME_OUTPUT_NAME target property.

   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.

       See also the RUNTIME_OUTPUT_NAME_<CONFIG> target property.

   SKIP_BUILD_RPATH
       Should rpaths be used for the build tree.

       SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic 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.

   SOURCE_DIR
       This read-only property reports the value of the CMAKE_CURRENT_SOURCE_DIR variable in  the
       directory in which the target was defined.

   SOURCES
       Source names specified for a target.

       List of sources specified for a target.

   SOVERSION
       What version number is this target.

       For  shared  libraries  VERSION and SOVERSION can be used to specify the build version and
       API version respectively.  When building or installing appropriate symlinks are created if
       the  platform  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.

   Windows Versions
       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.

   Mach-O Versions
       For  shared  libraries  and executables on Mach-O systems (e.g. macOS, iOS), the SOVERSION
       property corresponds to compatibility version and VERSION to  current  version.   See  the
       FRAMEWORK target property for an example.  Versions of Mach-O binaries may be checked with
       the otool -L <binary> command.

   STATIC_LIBRARY_FLAGS_<CONFIG>
       Per-configuration archiver (or MSVC librarian) flags for a static library target.

       This is the configuration-specific version of STATIC_LIBRARY_FLAGS.

       NOTE:
          This property has been superseded by STATIC_LIBRARY_OPTIONS property.

   STATIC_LIBRARY_FLAGS
       Archiver (or MSVC librarian) flags for a static library target.  Targets that  are  shared
       libraries,  modules,  or  executables  need  to  use the LINK_OPTIONS or LINK_FLAGS target
       properties.

       The STATIC_LIBRARY_FLAGS property, managed as a string, can be used to add extra flags  to
       the  link  step of a static library target.  STATIC_LIBRARY_FLAGS_<CONFIG> will add to the
       configuration <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO, …

       NOTE:
          This property has been superseded by STATIC_LIBRARY_OPTIONS property.

   STATIC_LIBRARY_OPTIONS
       Archiver (or MSVC librarian) flags for a static library target.  Targets that  are  shared
       libraries, modules, or executables need to use the LINK_OPTIONS target property.

       This property holds a semicolon-separated list of options specified so far for its target.
       Use set_target_properties() or set_property() commands to set its content.

       Contents of STATIC_LIBRARY_OPTIONS may use “generator expressions” with the syntax $<...>.
       See   the  cmake-generator-expressions(7)  manual  for  available  expressions.   See  the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       NOTE:
          This property must be used in preference to STATIC_LIBRARY_FLAGS property.

   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 executable.

   Swift_DEPENDENCIES_FILE
       This  property  sets the path for the Swift dependency file (swiftdep) for the target.  If
       one is not specified, it will default to <TARGET>.swiftdeps.

   Swift_LANGUAGE_VERSION
       This property sets the language version for the Swift sources in the target.   If  one  is
       not  specified,  it will default to <CMAKE_Swift_LANGUAGE_VERSION> if specified, otherwise
       it is the latest version supported by the compiler.

   Swift_MODULE_DIRECTORY
       Specify output directory for Swift modules provided by the target.

       If the target contains Swift source files, this  specifies  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_Swift_MODULE_DIRECTORY  is  set  when  a  target  is  created  its  value is used to
       initialise this property.

   Swift_MODULE_NAME
       This property specifies the name of the Swift module.  It is defaulted to the name of  the
       target.

   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,  OBJECT_LIBRARY,  INTERFACE_LIBRARY,
       EXECUTABLE or one of the internal target types.

   UNITY_BUILD
       When  this  property is set to true, the target source files will be combined into batches
       for faster compilation.  This is done by creating a (set of) unity sources which  #include
       the  original  sources, then compiling these unity sources instead of the originals.  This
       is known as a Unity or Jumbo build.   The  UNITY_BUILD_BATCH_SIZE  property  controls  the
       upper limit on how many sources can be combined per unity source file.

       Unity builds are not currently supported for all languages.  CMake version 3.16.3 supports
       combining C and CXX source files.  For targets that mix source files from  more  than  one
       language,  CMake  will  separate  the languages such that each generated unity source file
       only contains sources for a single language.

       This property is initialized by the value of the CMAKE_UNITY_BUILD variable when a  target
       is created.

       NOTE:
          Projects   should   not  directly  set  the  UNITY_BUILD  property  or  its  associated
          CMAKE_UNITY_BUILD variable to true.  Depending on the capabilities of the build machine
          and  compiler  used,  it  might  or  might  not  be appropriate to enable unity builds.
          Therefore, this feature should be under developer  control,  which  would  normally  be
          through  the developer choosing whether or not to set the CMAKE_UNITY_BUILD variable on
          the cmake(1) command line or some other equivalent method.  However, it IS  recommended
          to  set  the  UNITY_BUILD  target  property to false if it is known that enabling unity
          builds for the target can lead to problems.

   ODR (One definition rule) errors
       When multiple source files are included into one source file, as is done for unity builds,
       it  can  potentially  lead  to  ODR  errors.   CMake provides a number of measures to help
       address such problems:

       • Any  source  file   that   has   a   non-empty   COMPILE_OPTIONS,   COMPILE_DEFINITIONS,
         COMPILE_FLAGS,  or INCLUDE_DIRECTORIES source property will not be combined into a unity
         source.

       • Projects can prevent an individual source file from being combined into a  unity  source
         by  setting  its SKIP_UNITY_BUILD_INCLUSION source property to true.  This can be a more
         effective way to prevent problems with specific files than disabling unity builds for an
         entire target.

       • The UNITY_BUILD_CODE_BEFORE_INCLUDE and UNITY_BUILD_CODE_AFTER_INCLUDE target properties
         can be used to inject code into the unity source files before and after  every  #include
         statement.

       • The  order  of  source  files  added  to  the  target  via  commands like add_library(),
         add_executable() or target_sources() will be preserved in  the  generated  unity  source
         files.   This  can  be  used  to  manually  enforce  a  specific  grouping  based on the
         UNITY_BUILD_BATCH_SIZE target property.

   UNITY_BUILD_BATCH_SIZE
       Specifies the maximum number of source files that can  be  combined  into  any  one  unity
       source  file  when  unity  builds  are  enabled  by  the UNITY_BUILD target property.  The
       original source files will be distributed across as many unity source files  as  necessary
       to honor this limit.

       The  initial  value  for  this  property  is  taken  from the CMAKE_UNITY_BUILD_BATCH_SIZE
       variable when the target is created.  If that variable has not been set, the initial value
       will be 8.

       The  batch size needs to be selected carefully.  If set too high, the size of the combined
       source files could result in the compiler using excessive memory or hitting other  similar
       limits.   In  extreme cases, this can even result in build failure.  On the other hand, if
       the batch size is too low, there will be little gain in build performance.

       Although strongly discouraged, the batch size may be set to a value of 0  to  combine  all
       the  sources  for  the target into a single unity file, regardless of how many sources are
       involved.  This runs the risk of creating an  excessively  large  unity  source  file  and
       negatively impacting the build performance, so a value of 0 is not generally recommended.

   UNITY_BUILD_CODE_AFTER_INCLUDE
       Code  snippet  which  is  included  verbatim  by  the UNITY_BUILD feature just after every
       #include statement in the generated unity source files.  For example:

          set(after [[
          #if defined(NOMINMAX)
          #undef NOMINMAX
          #endif
          ]])
          set_target_properties(myTarget PROPERTIES
            UNITY_BUILD_CODE_AFTER_INCLUDE "${after}"
          )

       See also UNITY_BUILD_CODE_BEFORE_INCLUDE.

   UNITY_BUILD_CODE_BEFORE_INCLUDE
       Code snippet which is included verbatim by  the  UNITY_BUILD  feature  just  before  every
       #include statement in the generated unity source files.  For example:

          set(before [[
          #if !defined(NOMINMAX)
          #define NOMINMAX
          #endif
          ]])
          set_target_properties(myTarget PROPERTIES
            UNITY_BUILD_CODE_BEFORE_INCLUDE "${before}"
          )

       See also UNITY_BUILD_CODE_AFTER_INCLUDE.

   VERSION
       What version number is this target.

       For  shared  libraries  VERSION and SOVERSION can be used to specify the build version and
       API version respectively.  When building or installing appropriate symlinks are created if
       the  platform  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
       symlinks are created if the platform supports symlinks.

   Windows Versions
       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.

   Mach-O Versions
       For shared libraries and executables on Mach-O systems (e.g. macOS,  iOS),  the  SOVERSION
       property  correspond  to  compatibility  version  and VERSION to current version.  See the
       FRAMEWORK target property for an example.  Versions of Mach-O binaries may be checked with
       the otool -L <binary> command.

   VISIBILITY_INLINES_HIDDEN
       Whether to add a compile flag to hide symbols of inline functions

       The  VISIBILITY_INLINES_HIDDEN  property  determines whether a flag for hiding symbols for
       inline functions, such as -fvisibility-inlines-hidden, should be used  when  invoking  the
       compiler.   This  property affects compilation in sources of all types of targets (subject
       to policy CMP0063).

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

   VS_CONFIGURATION_TYPE
       Visual Studio project configuration type.

       Sets  the ConfigurationType attribute for a generated Visual Studio project.  The property
       value may use generator expressions.  If this property is set, it  overrides  the  default
       setting that is based on the target type (e.g. StaticLibrary, Application, …).

       Supported on Visual Studio Generators for VS 2010 and higher.

   VS_DEBUGGER_COMMAND
       Sets the local debugger command for Visual Studio C++ targets.  The property value may use
       generator expressions.  This is defined in <LocalDebuggerCommand>  in  the  Visual  Studio
       project file.

       This  property  only  works  for  Visual  Studio  2010  and  above; it is ignored on other
       generators.

   VS_DEBUGGER_COMMAND_ARGUMENTS
       Sets the local debugger command  line  arguments  for  Visual  Studio  C++  targets.   The
       property    value    may    use    generator    expressions.     This    is   defined   in
       <LocalDebuggerCommandArguments> in the Visual Studio project file.

       This property only works for Visual  Studio  2010  and  above;  it  is  ignored  on  other
       generators.

   VS_DEBUGGER_ENVIRONMENT
       Sets the local debugger environment for Visual Studio C++ targets.  The property value may
       use generator expressions.  This is defined in <LocalDebuggerEnvironment>  in  the  Visual
       Studio project file.

       This  property  only  works  for  Visual  Studio  2010  and  above; it is ignored on other
       generators.

   VS_DEBUGGER_WORKING_DIRECTORY
       Sets the local debugger working directory for Visual Studio  C++  targets.   The  property
       value  may  use generator expressions.  This is defined in <LocalDebuggerWorkingDirectory>
       in the Visual Studio project file.

       This property only works for Visual  Studio  2010  and  above;  it  is  ignored  on  other
       generators.

   VS_DESKTOP_EXTENSIONS_VERSION
       Visual Studio Windows 10 Desktop Extensions Version

       Specifies the version of the Desktop Extensions that should be included in the target. For
       example 10.0.10240.0. If the value is not specified, the Desktop Extensions  will  not  be
       included.  To  use  the same version of the extensions as the Windows 10 SDK that is being
       used, you can use the CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION variable.

   VS_DOTNET_REFERENCE_<refname>
       Visual Studio managed project .NET reference with name <refname> and hint path.

       Adds one .NET reference to generated Visual Studio project. The reference  will  have  the
       name <refname> and will point to the assembly given as value of the property.

       See also VS_DOTNET_REFERENCES and VS_DOTNET_REFERENCES_COPY_LOCAL

   VS_DOTNET_REFERENCEPROP_<refname>_TAG_<tagname>
       Defines an XML property <tagname> for a .NET reference <refname>.

       Reference  properties  can  be  set  for  .NET  references which are defined by the target
       properties  VS_DOTNET_REFERENCES,  VS_DOTNET_REFERENCE_<refname>  and  also  for   project
       references to other C# targets which are established by target_link_libraries().

       This  property  is  only  applicable  to  C# targets and Visual Studio generators 2010 and
       later.

   VS_DOTNET_REFERENCES
       Visual Studio managed project .NET references

       Adds one or more semicolon-delimited .NET references to a generated Visual Studio project.
       For example, “System;System.Windows.Forms”.

   VS_DOTNET_REFERENCES_COPY_LOCAL
       Sets the Copy Local property for all .NET hint references in the target

       Boolean  property  to  enable/disable copying of .NET hint references to output directory.
       The default is ON.

   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”.

       This   property   is   deprecated    and    should    not    be    used    anymore.    Use
       DOTNET_TARGET_FRAMEWORK_VERSION instead.

   VS_DPI_AWARE
       Set  the  Manifest  Tool  -> Input and Output -> DPI Awareness in the Visual Studio target
       project properties.

       Valid values are PerMonitor, ON, or OFF.

       For example:

          add_executable(myproject myproject.cpp)
          set_property(TARGET myproject PROPERTY VS_DPI_AWARE "PerMonitor")

   VS_GLOBAL_KEYWORD
       Visual Studio project keyword for VS 10 (2010) and newer.

       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 managed C++ unit test project.

       Use the VS_KEYWORD target property to set the keyword  for  Visual  Studio  9  (2008)  and
       older.

   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 testing 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_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 better if VS_GLOBAL_QtVersion is  set  to  the  version  FindQt4.cmake  found.   For
       example, “4.7.3”

   VS_IOT_EXTENSIONS_VERSION
       Visual Studio Windows 10 IoT Extensions Version

       Specifies  the  version  of  the IoT Extensions that should be included in the target. For
       example 10.0.10240.0. If the value is not  specified,  the  IoT  Extensions  will  not  be
       included.  To  use  the same version of the extensions as the Windows 10 SDK that is being
       used, you can use the CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION variable.

   VS_IOT_STARTUP_TASK
       Visual Studio Windows 10 IoT Continuous Background Task

       Specifies that the target should be compiled as a Continuous Background Task library.

   VS_JUST_MY_CODE_DEBUGGING
       Enable Just My Code with Visual Studio debugger.

       Supported on Visual Studio Generators for VS 2010 and higher, Makefile Generators and  the
       Ninja generators.

       This  property is initialized by the CMAKE_VS_JUST_MY_CODE_DEBUGGING variable if it is set
       when a target is created.

   VS_KEYWORD
       Visual Studio project keyword for VS 9 (2008) and older.

       Can be set to change the visual studio keyword, for example Qt integration works better if
       this is set to Qt4VSv1.0.

       Use  the  VS_GLOBAL_KEYWORD target property to set the keyword for Visual Studio 10 (2010)
       and newer.

   VS_MOBILE_EXTENSIONS_VERSION
       Visual Studio Windows 10 Mobile Extensions Version

       Specifies the version of the Mobile Extensions that should be included in the target.  For
       example  10.0.10240.0.  If  the  value is not specified, the Mobile Extensions will not be
       included. To use the same version of the extensions as the Windows 10 SDK  that  is  being
       used, you can use the CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION variable.

   VS_NO_SOLUTION_DEPLOY
       Specify  that  the  target  should not be marked for deployment to a Windows CE or Windows
       Phone device in the generated Visual Studio solution.

       Be default, all EXE and shared library (DLL) targets are marked to deploy  to  the  target
       device in the generated Visual Studio solution.

       Generator expressions are supported.

       There are reasons one might want to exclude a target / generated project from deployment:

       • The library or executable may not be necessary in the primary deploy/debug scenario, and
         excluding from deployment saves time in the develop/download/debug cycle.

       • There may be insufficient space on the target device to accommodate  all  of  the  build
         products.

       • Visual Studio 2013 requires a target device IP address be entered for each target marked
         for deployment.  For large numbers of targets, this can be tedious.  NOTE: Visual Studio
         will  deploy  all  project  dependencies  of  a  project tagged for deployment to the IP
         address configured for that project even  if  those  dependencies  are  not  tagged  for
         deployment.

   Example 1
       This shows setting the variable for the target foo.

          add_library(foo SHARED foo.cpp)
          set_property(TARGET foo PROPERTY VS_NO_SOLUTION_DEPLOY ON)

   Example 2
       This shows setting the variable for the Release configuration only.

          add_library(foo SHARED foo.cpp)
          set_property(TARGET foo PROPERTY VS_NO_SOLUTION_DEPLOY "$<CONFIG:Release>")

   VS_PACKAGE_REFERENCES
       Visual Studio package references for nuget.

       Adds  one  or  more  semicolon-delimited  package  references to a generated Visual Studio
       project.  The  version  of  the  package  will  be  underscore  delimited.  For   example,
       boost_1.7.0;nunit_3.12.*.

          set_property(TARGET ${TARGET_NAME} PROPERTY
            VS_PACKAGE_REFERENCES "boost_1.7.0")

   VS_PROJECT_IMPORT
       Visual Studio managed project imports

       Adds  to a generated Visual Studio project one or more semicolon-delimited paths to .props
       files  needed  when  building  projects  from   some   NuGet   packages.    For   example,
       my_packages_path/MyPackage.1.0.0/build/MyPackage.props.

   VS_SCC_AUXPATH
       Visual Studio Source Code Control Aux Path.

       Can be set to change the visual studio source code control auxpath 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_SDK_REFERENCES
       Visual  Studio  project  SDK  references.   Specify  a  semicolon-separated  list  of  SDK
       references   to   be   added   to   a    generated    Visual    Studio    project,    e.g.
       Microsoft.AdMediatorWindows81, Version=1.0.

   VS_USER_PROPS
       Sets  the  user  props  file  to  be  included  in the visual studio C++ project file. The
       standard path is $(UserRootDir)\\Microsoft.Cpp.$(Platform).user.props, which  is  in  most
       cases the same as %LOCALAPPDATA%\\Microsoft\\MSBuild\\v4.0\\Microsoft.Cpp.Win32.user.props
       or %LOCALAPPDATA%\\Microsoft\\MSBuild\\v4.0\\Microsoft.Cpp.x64.user.props.

       The *.user.props files  can  be  used  for  Visual  Studio  wide  configuration  which  is
       independent from cmake.

   VS_WINDOWS_TARGET_PLATFORM_MIN_VERSION
       Visual Studio Windows Target Platform Minimum Version

       For  Windows  10.  Specifies  the  minimum  version  of the OS that is being targeted. For
       example   10.0.10240.0.   If   the   value   is    not    specified,    the    value    of
       CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION  will  be used on WindowsStore projects otherwise
       the target platform minimum version will not be specified for the project.

   VS_WINRT_COMPONENT
       Mark a target as a Windows Runtime component for the Visual Studio generator.  Compile the
       target  with  C++/CX  language  extensions  for  Windows  Runtime.   For SHARED and MODULE
       libraries, this also defines the _WINRT_DLL preprocessor macro.

       NOTE:
          Currently this is implemented only by Visual Studio generators.  Support may  be  added
          to other generators in the future.

   VS_WINRT_EXTENSIONS
       Deprecated.   Use  VS_WINRT_COMPONENT  instead.  This property was an experimental partial
       implementation of that one.

   VS_WINRT_REFERENCES
       Visual Studio project Windows Runtime Metadata references

       Adds one or more  semicolon-delimited  WinRT  references  to  a  generated  Visual  Studio
       project.  For example, “Windows;Windows.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  console  application.   See  the  CMAKE_MFC_FLAG variable documentation to
       configure use of the Microsoft Foundation Classes (MFC)  for  WinMain  executables.   This
       property  is  initialized by the value of the CMAKE_WIN32_EXECUTABLE variable if it is set
       when a target is created.

   WINDOWS_EXPORT_ALL_SYMBOLS
       This property is implemented only for MS-compatible tools on Windows.

       Enable this boolean property to automatically create a module definition (.def) file  with
       all  global symbols found in the input .obj files for a SHARED library (or executable with
       ENABLE_EXPORTS) on Windows.  The module definition file  will  be  passed  to  the  linker
       causing   all   symbols   to  be  exported  from  the  .dll.   For  global  data  symbols,
       __declspec(dllimport) must still be used when compiling against the code in the .dll.  All
       other  function  symbols  will  be  automatically  exported and imported by callers.  This
       simplifies porting projects to Windows by reducing the need for explicit dllexport markup,
       even in C++ classes.

       When  this  property  is  enabled, zero or more .def files may also be specified as source
       files of the target.  The exports named by these files will be merged with those  detected
       from  the  object  files  to  generate a single module definition file to be passed to the
       linker.  This can be used to export symbols from a .dll that are not in any of its  object
       files but are added by the linker from dependencies (e.g. msvcrt.lib).

       This property is initialized by the value of the CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS variable
       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 generators.

       See  the CMAKE_XCODE_ATTRIBUTE_<an-attribute> variable to set attributes on all targets in
       a directory tree.

       Contents of XCODE_ATTRIBUTE_<an-attribute> may use “generator expressions” with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   XCODE_EXPLICIT_FILE_TYPE
       Set the Xcode explicitFileType attribute on its reference to a target.  CMake  computes  a
       default based on target type but can be told explicitly with this property.

       See also XCODE_PRODUCT_TYPE.

   XCODE_GENERATE_SCHEME
       If  enabled,  the  Xcode generator will generate schema files.  These are useful to invoke
       analyze, archive, build-for-testing and test actions from the command line.

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

       The following target properties overwrite the default of the corresponding settings on the
       “Diagnostic” tab for each schema file.  Each of those is  initialized  by  the  respective
       CMAKE_ variable at target creation time.

       • XCODE_SCHEME_ADDRESS_SANITIZERXCODE_SCHEME_ADDRESS_SANITIZER_USE_AFTER_RETURNXCODE_SCHEME_DISABLE_MAIN_THREAD_CHECKERXCODE_SCHEME_DYNAMIC_LIBRARY_LOADSXCODE_SCHEME_DYNAMIC_LINKER_API_USAGEXCODE_SCHEME_GUARD_MALLOCXCODE_SCHEME_MAIN_THREAD_CHECKER_STOPXCODE_SCHEME_MALLOC_GUARD_EDGESXCODE_SCHEME_MALLOC_SCRIBBLEXCODE_SCHEME_MALLOC_STACKXCODE_SCHEME_THREAD_SANITIZERXCODE_SCHEME_THREAD_SANITIZER_STOPXCODE_SCHEME_UNDEFINED_BEHAVIOUR_SANITIZERXCODE_SCHEME_UNDEFINED_BEHAVIOUR_SANITIZER_STOPXCODE_SCHEME_ZOMBIE_OBJECTS

       The  following target properties will be applied on the “Info”, “Arguments”, and “Options”
       tab:

       • XCODE_SCHEME_ARGUMENTSXCODE_SCHEME_DEBUG_AS_ROOTXCODE_SCHEME_DEBUG_DOCUMENT_VERSIONINGXCODE_SCHEME_ENVIRONMENTXCODE_SCHEME_EXECUTABLE

   XCODE_PRODUCT_TYPE
       Set the Xcode productType attribute on its  reference  to  a  target.   CMake  computes  a
       default based on target type but can be told explicitly with this property.

       See also XCODE_EXPLICIT_FILE_TYPE.

   XCTEST
       This target is a XCTest CFBundle on the Mac.

       This property will usually get set via the xctest_add_bundle() macro in FindXCTest module.

       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.

       This property depends on BUNDLE to be effective.

PROPERTIES ON TESTS

   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.

   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.

   COST
       This property describes the cost of a test.  When parallel testing is  enabled,  tests  in
       the  test set will be run in descending order of cost.  Projects can explicitly define the
       cost of a test by setting this property to a floating point value.

       When the cost of a test is not defined by the project, ctest will initially use a  default
       cost  of  0.   It computes a weighted average of the cost each time a test is run and uses
       that as an improved estimate of the cost for the next run.  The more a test is  re-run  in
       the same build directory, the more representative the cost should become.

   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. The results of those
       tests are not considered, the dependency relationship is purely  for  order  of  execution
       (i.e. it is really just a run after relationship). Consider using test fixtures with setup
       tests if a dependency with successful completion is required (see FIXTURES_REQUIRED).

   DISABLED
       If set to True, the test will be skipped and its status will be ‘Not Run’. A DISABLED test
       will  not  be  counted  in  the  total  number  of tests and its completion status will be
       reported to CDash as Disabled.

       A DISABLED test does not participate in test fixture dependency resolution.  If a DISABLED
       test has fixture requirements defined in its FIXTURES_REQUIRED property, it will not cause
       setup or cleanup tests for those fixtures to be added to the test set.

       If a test with the FIXTURES_SETUP property set is DISABLED, the fixture behavior  will  be
       as  though that setup test was passing and any test case requiring that fixture will still
       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 expressions, the  test  will  fail.
       Example:

          set_tests_properties(mytest PROPERTIES
            FAIL_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"
          )

       FAIL_REGULAR_EXPRESSION expects a list of regular expressions.

   FIXTURES_CLEANUP
       Specifies  a list of fixtures for which the test is to be treated as a cleanup test. These
       fixture names are distinct from  test  case  names  and  are  not  required  to  have  any
       similarity to the names of tests associated with them.

       Fixture cleanup tests are ordinary tests with all of the usual test functionality. Setting
       the FIXTURES_CLEANUP property for a test has two primary effects:

       • CTest will ensure the test executes after all other tests which list any of the fixtures
         in its FIXTURES_REQUIRED property.

       • If  CTest  is asked to run only a subset of tests (e.g. using regular expressions or the
         --rerun-failed option) and the cleanup test is not in the set of tests to run,  it  will
         automatically  be  added  if  any  tests  in  the  set  require  any  fixture  listed in
         FIXTURES_CLEANUP.

       A cleanup test can have multiple fixtures listed in its FIXTURES_CLEANUP property. It will
       execute  only  once for the whole CTest run, not once for each fixture. A fixture can also
       have more than one cleanup test defined.  If  there  are  multiple  cleanup  tests  for  a
       fixture,  projects  can  control  their  order  with  the  usual  DEPENDS test property if
       necessary.

       A cleanup test is allowed to require other fixtures, but not any  fixture  listed  in  its
       FIXTURES_CLEANUP property. For example:

          # Ok: Dependent fixture is different to cleanup
          set_tests_properties(cleanupFoo PROPERTIES
            FIXTURES_CLEANUP  Foo
            FIXTURES_REQUIRED Bar
          )

          # Error: cannot require same fixture as cleanup
          set_tests_properties(cleanupFoo PROPERTIES
            FIXTURES_CLEANUP  Foo
            FIXTURES_REQUIRED Foo
          )

       Cleanup  tests  will  execute  even if setup or regular tests for that fixture fail or are
       skipped.

       See FIXTURES_REQUIRED for a more complete discussion of how to use test fixtures.

   FIXTURES_REQUIRED
       Specifies a list of fixtures the test requires. Fixture names are case sensitive and  they
       are not required to have any similarity to test names.

       Fixtures are a way to attach setup and cleanup tasks to a set of tests. If a test requires
       a given fixture, then all tests marked as setup tasks for that fixture  will  be  executed
       first  (once  for  the whole set of tests, not once per test requiring the fixture). After
       all tests requiring a particular fixture have  completed,  CTest  will  ensure  all  tests
       marked  as  cleanup  tasks  for  that fixture are then executed. Tests are marked as setup
       tasks with the FIXTURES_SETUP property and as  cleanup  tasks  with  the  FIXTURES_CLEANUP
       property.  If any of a fixture’s setup tests fail, all tests listing that fixture in their
       FIXTURES_REQUIRED property will not be executed. The cleanup tests for  the  fixture  will
       always be executed, even if some setup tests fail.

       When  CTest  is  asked  to  execute  only  a  subset  of tests (e.g. by the use of regular
       expressions  or  when  run  with  the  --rerun-failed  command  line  option),   it   will
       automatically  add  any  setup  or cleanup tests for fixtures required by any of the tests
       that are in the execution set. This behavior can be overridden with the -FS, -FC  and  -FA
       command line options to ctest(1) if desired.

       Since  setup  and cleanup tasks are also tests, they can have an ordering specified by the
       DEPENDS test property just like any other tests.  This can be exploited to implement setup
       or cleanup using multiple tests for a single fixture to modularise setup or cleanup logic.

       The  concept  of  a fixture is different to that of a resource specified by RESOURCE_LOCK,
       but they may be used together. A fixture defines a set of  tests  which  share  setup  and
       cleanup  requirements, whereas a resource lock has the effect of ensuring a particular set
       of tests do not run in parallel. Some situations may need  both,  such  as  setting  up  a
       database,  serialising test access to that database and deleting the database again at the
       end. For such cases, tests would populate  both  FIXTURES_REQUIRED  and  RESOURCE_LOCK  to
       combine  the  two behaviours. Names used for RESOURCE_LOCK have no relationship with names
       of fixtures, so note that a resource lock does not imply a fixture and vice versa.

       Consider the following example which represents a database test scenario similar  to  that
       mentioned above:

          add_test(NAME testsDone   COMMAND emailResults)
          add_test(NAME fooOnly     COMMAND testFoo)
          add_test(NAME dbOnly      COMMAND testDb)
          add_test(NAME dbWithFoo   COMMAND testDbWithFoo)
          add_test(NAME createDB    COMMAND initDB)
          add_test(NAME setupUsers  COMMAND userCreation)
          add_test(NAME cleanupDB   COMMAND deleteDB)
          add_test(NAME cleanupFoo  COMMAND removeFoos)

          set_tests_properties(setupUsers PROPERTIES DEPENDS createDB)

          set_tests_properties(createDB   PROPERTIES FIXTURES_SETUP    DB)
          set_tests_properties(setupUsers PROPERTIES FIXTURES_SETUP    DB)
          set_tests_properties(cleanupDB  PROPERTIES FIXTURES_CLEANUP  DB)
          set_tests_properties(cleanupFoo PROPERTIES FIXTURES_CLEANUP  Foo)
          set_tests_properties(testsDone  PROPERTIES FIXTURES_CLEANUP  "DB;Foo")

          set_tests_properties(fooOnly    PROPERTIES FIXTURES_REQUIRED Foo)
          set_tests_properties(dbOnly     PROPERTIES FIXTURES_REQUIRED DB)
          set_tests_properties(dbWithFoo  PROPERTIES FIXTURES_REQUIRED "DB;Foo")

          set_tests_properties(dbOnly dbWithFoo createDB setupUsers cleanupDB
                               PROPERTIES RESOURCE_LOCK DbAccess)

       Key points from this example:

       • Two  fixtures are defined: DB and Foo. Tests can require a single fixture as fooOnly and
         dbOnly do, or they can depend on multiple fixtures like dbWithFoo does.

       • A DEPENDS relationship is set up to ensure setupUsers happens after  createDB,  both  of
         which  are  setup  tests  for  the  DB fixture and will therefore be executed before the
         dbOnly and dbWithFoo tests automatically.

       • No explicit DEPENDS relationships were needed to make the setup tests run before or  the
         cleanup tests run after the regular tests.

       • The Foo fixture has no setup tests defined, only a single cleanup test.

       • testsDone  is  a cleanup test for both the DB and Foo fixtures.  Therefore, it will only
         execute once regular tests for both fixtures have finished (i.e. after  fooOnly,  dbOnly
         and  dbWithFoo).  No  DEPENDS relationship was specified for testsDone, so it is free to
         run before, after or concurrently with other cleanup tests for either fixture.

       • The setup and cleanup  tests  never  list  the  fixtures  they  are  for  in  their  own
         FIXTURES_REQUIRED  property,  as  that would result in a dependency on themselves and be
         considered an error.

   FIXTURES_SETUP
       Specifies a list of fixtures for which the test is to be treated as a  setup  test.  These
       fixture  names  are  distinct  from  test  case  names  and  are  not required to have any
       similarity to the names of tests associated with them.

       Fixture setup tests are ordinary tests with all of the usual test  functionality.  Setting
       the FIXTURES_SETUP property for a test has two primary effects:

       • CTest  will  ensure  the  test  executes  before  any other test which lists the fixture
         name(s) in its FIXTURES_REQUIRED property.

       • If CTest is asked to run only a subset of tests (e.g. using regular expressions  or  the
         --rerun-failed  option)  and  the  setup test is not in the set of tests to run, it will
         automatically be  added  if  any  tests  in  the  set  require  any  fixture  listed  in
         FIXTURES_SETUP.

       A  setup  test  can  have multiple fixtures listed in its FIXTURES_SETUP property. It will
       execute only once for the whole CTest run, not once for each fixture. A fixture  can  also
       have  more  than  one setup test defined. If there are multiple setup tests for a fixture,
       projects can control their order with the usual DEPENDS test property if necessary.

       A setup test is allowed to require other fixtures, but  not  any  fixture  listed  in  its
       FIXTURES_SETUP property. For example:

          # Ok: dependent fixture is different to setup
          set_tests_properties(setupFoo PROPERTIES
            FIXTURES_SETUP    Foo
            FIXTURES_REQUIRED Bar
          )

          # Error: cannot require same fixture as setup
          set_tests_properties(setupFoo PROPERTIES
            FIXTURES_SETUP    Foo
            FIXTURES_REQUIRED Foo
          )

       If  any  of  a  fixture’s  setup tests fail, none of the tests listing that fixture in its
       FIXTURES_REQUIRED property will be run. Cleanup tests will, however, still be executed.

       See FIXTURES_REQUIRED for a more complete discussion of how to use test fixtures.

   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.  Example:

          set_tests_properties(mytest PROPERTIES
            PASS_REGULAR_EXPRESSION "TestPassed;All ok"
          )

       PASS_REGULAR_EXPRESSION expects a list of regular expressions.

   PROCESSOR_AFFINITY
       Set to a true value to ask CTest to launch the test process with CPU affinity for a  fixed
       set of processors.  If enabled and supported for the current platform, CTest will choose a
       set of processors to place in the CPU affinity mask when launching the test process.   The
       number  of  processors  in  the  set  is determined by the PROCESSORS test property or the
       number of processors available to CTest, whichever is  smaller.   The  set  of  processors
       chosen  will  be disjoint from the processors assigned to other concurrently running tests
       that also have the PROCESSOR_AFFINITY property enabled.

   PROCESSORS
       Set to specify how many process slots this test requires.  If not set, the  default  is  1
       processor.

       Denotes  the number of processors that this test will require.  This is typically used for
       MPI tests, and should be used in conjunction with the ctest_test() PARALLEL_LEVEL option.

       This will also be used to display a weighted test timing result in  label  and  subproject
       summaries  in  the  command  line output of ctest(1). The wall clock time for the test run
       will be multiplied by this property to give a better idea of how much cpu  resource  CTest
       allocated for the test.

       See also the PROCESSOR_AFFINITY test property.

   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_GROUPS
       Specify  resources  required  by  a test, grouped in a way that is meaningful to the test.
       See resource allocation for more information on how  this  property  integrates  into  the
       CTest resource allocation feature.

       The  RESOURCE_GROUPS  property  is  a semicolon-separated list of group descriptions. Each
       entry consists of an optional number of groups using the description followed by a  series
       of  resource  requirements for those groups. These requirements (and the number of groups)
       are separated by commas. The resource requirements consist of the name of a resource type,
       followed  by  a  colon,  followed  by  an  unsigned integer specifying the number of slots
       required on one resource of the given type.

       The RESOURCE_GROUPS property tells CTest what resources a test expects to use grouped in a
       way  meaningful  to  the  test.   The  test  itself must read the environment variables to
       determine which resources have been allocated to each group.  For example, each group  may
       correspond to a process the test will spawn when executed.

       Consider the following example:

          add_test(NAME MyTest COMMAND MyExe)
          set_property(TEST MyTest PROPERTY RESOURCE_GROUPS
            "2,gpus:2"
            "gpus:4,crypto_chips:2")

       In  this  example, there are two group descriptions (implicitly separated by a semicolon.)
       The content of the first description is 2,gpus:2. This  description  specifies  2  groups,
       each of which requires 2 slots from a single GPU. The content of the second description is
       gpus:4,crypto_chips:2. This description does not specify a group count, so a default of  1
       is  assumed.   This  single  group  requires  4 slots from a single GPU and 2 slots from a
       single cryptography chip. In total, 3 resource groups are specified for  this  test,  each
       with its own unique requirements.

       Note  that  the  number of slots following the resource type specifies slots from a single
       instance of the resource.  If  the  resource  group  can  tolerate  receiving  slots  from
       different  instances  of  the  same  resource,  it  can  indicate  this  by  splitting the
       specification into multiple requirements of one slot. For example:

          add_test(NAME MyTest COMMAND MyExe)
          set_property(TEST MyTest PROPERTY RESOURCE_GROUPS
            "gpus:1,gpus:1,gpus:1,gpus:1")

       In this case, the single resource group indicates that it needs four  GPU  slots,  all  of
       which may come from separate GPUs (though they don’t have to; CTest may still assign slots
       from the same GPU.)

       When CTest sets the environment variables for a test, it assigns a group number  based  on
       the  group  description, starting at 0 on the left and the number of groups minus 1 on the
       right. For example, in the example above, the two groups in the  first  description  would
       have IDs of 0 and 1, and the single group in the second description would have an ID of 2.

       Both the RESOURCE_GROUPS and RESOURCE_LOCK properties serve similar purposes, but they are
       distinct  and  orthogonal.  Resources  specified  by   RESOURCE_GROUPS   do   not   affect
       RESOURCE_LOCK,  and  vice versa.  Whereas RESOURCE_LOCK is a simpler property that is used
       for locking one global resource, RESOURCE_GROUPS is a more advanced property  that  allows
       multiple tests to simultaneously use multiple resources of the same type, specifying their
       requirements in a fine-grained manner.

   RESOURCE_LOCK
       Specify a list of resources that are locked by this test.

       If multiple tests specify  the  same  resource  lock,  they  are  guaranteed  not  to  run
       concurrently.

       See also FIXTURES_REQUIRED if the resource requires any setup or cleanup steps.

       Both the RESOURCE_GROUPS and RESOURCE_LOCK properties serve similar purposes, but they are
       distinct  and  orthogonal.  Resources  specified  by   RESOURCE_GROUPS   do   not   affect
       RESOURCE_LOCK,  and  vice versa.  Whereas RESOURCE_LOCK is a simpler property that is used
       for locking one global resource, RESOURCE_GROUPS is a more advanced property  that  allows
       multiple tests to simultaneously use multiple resources of the same type, specifying their
       requirements in a fine-grained manner.

   RUN_SERIAL
       Do not run this test in parallel with any other test.

       Use this option in conjunction with the ctest_test PARALLEL_LEVEL option to  specify  that
       this test should not be run in parallel with any other tests.

   SKIP_REGULAR_EXPRESSION
       If the output matches this regular expression the test will be marked as skipped.

       If  set,  if  the  output  matches  one of specified regular expressions, the test will be
       marked as skipped.  Example:

          set_property(TEST mytest PROPERTY
            SKIP_REGULAR_EXPRESSION "[^a-z]Skip" "SKIP" "Skipped"
          )

       SKIP_REGULAR_EXPRESSION expects a list of regular expressions.

       See also the SKIP_RETURN_CODE property.

   SKIP_RETURN_CODE
       Return code to mark a test as skipped.

       Sometimes only a test itself can determine if all requirements for the test  are  met.  If
       such  a situation should not be considered a hard failure a return code of the process can
       be specified that will mark the test as Not Run if it is encountered. Valid values are  in
       the range of 0 to 255, inclusive.

       See also the SKIP_REGULAR_EXPRESSION property.

   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_TEST_TIMEOUT.

   TIMEOUT_AFTER_MATCH
       Change a test’s timeout duration after a matching line is encountered in its output.

   Usage
          add_test(mytest ...)
          set_property(TEST mytest PROPERTY TIMEOUT_AFTER_MATCH "${seconds}" "${regex}")

   Description
       Allow a test seconds to complete after regex is encountered in its output.

       When  the  test  outputs  a line that matches regex its start time is reset to the current
       time and its timeout duration is changed to seconds.  Prior to this, the timeout  duration
       is  determined  by  the  TIMEOUT  property or the CTEST_TEST_TIMEOUT variable if either of
       these are set.  Because the test’s start time  is  reset,  its  execution  time  will  not
       include any time that was spent waiting for the matching output.

       TIMEOUT_AFTER_MATCH  is useful for avoiding spurious timeouts when your test must wait for
       some system resource to become available before it can execute.  Set TIMEOUT to  a  longer
       duration that accounts for resource acquisition and use TIMEOUT_AFTER_MATCH to control how
       long the actual test is allowed to run.

       If the required resource can be controlled by CTest you should use  RESOURCE_LOCK  instead
       of  TIMEOUT_AFTER_MATCH.   This  property  should  be  used  when only the test itself can
       determine when its required resources are available.

   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,  the test will be run with the working directory set to the binary
       directory associated with where the test was created  (i.e.  the  CMAKE_CURRENT_BINARY_DIR
       for where add_test() was called).

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.

   AUTOUIC_OPTIONS
       Additional options for uic when using AUTOUIC

       This  property  holds  additional  command  line  options  which  will be used when uic is
       executed during the build via AUTOUIC, i.e. it  is  equivalent  to  the  optional  OPTIONS
       argument of the qt4_wrap_ui() macro.

       By default it is empty.

       The options set on the .ui source file may override AUTOUIC_OPTIONS set on the target.

   EXAMPLE
          # ...
          set_property(SOURCE widget.ui PROPERTY AUTOUIC_OPTIONS "--no-protection")
          # ...

   AUTORCC_OPTIONS
       Additional options for rcc when using AUTORCC

       This  property  holds  additional  command  line  options  which  will be used when rcc is
       executed during the build via AUTORCC, i.e. it  is  equivalent  to  the  optional  OPTIONS
       argument of the qt4_add_resources() macro.

       By default it is empty.

       The options set on the .qrc source file may override AUTORCC_OPTIONS set on the target.

   EXAMPLE
          # ...
          set_property(SOURCE resources.qrc PROPERTY AUTORCC_OPTIONS "--compress;9")
          # ...

   COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a source file.

       The  COMPILE_DEFINITIONS property may be set to a semicolon-separated 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_<CONFIG>   where    <CONFIG>    is    an    upper-case    name    (ex.
       COMPILE_DEFINITIONS_DEBUG).

       CMake  will automatically drop some definitions that are not supported by the native build
       tool.  Xcode does not support per-configuration definitions on source files.

       Disclaimer: Most native build tools have poor support for escaping 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.

       Contents  of  COMPILE_DEFINITIONS  may  use cmake-generator-expressions(7) with the syntax
       $<...>.   See  the  cmake-generator-expressions(7)  manual  for   available   expressions.
       However, Xcode does not support per-config per-source settings, so expressions that depend
       on the build configuration are not allowed with that generator.

       Generator  expressions  should  be  preferred   instead   of   setting   the   alternative
       per-configuration property.

   COMPILE_FLAGS
       Additional flags to be added when compiling this source file.

       The  COMPILE_FLAGS  property,  managed as a string, sets additional compiler flags used to
       build source files.  Use COMPILE_DEFINITIONS to pass additional preprocessor definitions.

       Contents of COMPILE_FLAGS may use “generator expressions” with the syntax $<...>.  See the
       cmake-generator-expressions(7)  manual for available expressions.  However, Xcode does not
       support  per-config  per-source  settings,  so  expressions  that  depend  on  the   build
       configuration are not allowed with that generator.

       NOTE:
          This property has been superseded by the COMPILE_OPTIONS property.

   COMPILE_OPTIONS
       List of additional options to pass to the compiler.

       This property holds a semicolon-separated list of options and will be added to the list of
       compile flags when this source file builds.  Use COMPILE_DEFINITIONS  to  pass  additional
       preprocessor definitions and INCLUDE_DIRECTORIES to pass additional include directories.

       Contents  of  COMPILE_OPTIONS may use “generator expressions” with the syntax $<...>.  See
       the cmake-generator-expressions(7) manual for available expressions.  However, Xcode  does
       not  support  per-config  per-source  settings,  so  expressions  that depend on the build
       configuration are not allowed with that generator.

       NOTE:
          This property should be preferred over the COMPILE_FLAGS property.

   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 corresponding format flag  to  the  compiler.   Consider
       using  the  target-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 or CMake process.

       Tells the internal CMake engine that a source file is generated by an outside process such
       as  another build step, or the execution of CMake itself. This information is then used to
       exempt the file from any existence or validity checks. Generated files are created by  the
       execution of commands such as add_custom_command() and file(GENERATE).

       When a generated file created by an add_custom_command() command is explicitly listed as a
       source file for any target in the same directory  scope  (which  usually  means  the  same
       CMakeLists.txt  file),  CMake will automatically create a dependency to make sure the file
       is generated before building that target.

       Generated sources may be hidden in some IDE tools, while in others they  might  be  shown.
       For the special case of sources generated by CMake’s AUTOMOC or AUTORCC functionality, the
       AUTOGEN_SOURCE_GROUP, AUTOMOC_SOURCE_GROUP and AUTORCC_SOURCE_GROUP target properties  may
       influence where the generated sources are grouped in the project’s file lists.

   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 computed.

       By setting this property to ON, you can disable compilation of the given source file, even
       if it should be compiled because it is part of the library’s/executable’s sources.

       This is useful if you have some source files which you somehow pre-process, and  then  add
       these pre-processed sources via add_library() or add_executable(). Normally, in IDE, there
       would be no reference of the original sources, only of these pre-processed sources. So  by
       setting  this  property  for  all the original source files to ON, and then either calling
       add_library() or add_executable() while passing both the  pre-processed  sources  and  the
       original  sources,  or  by  using  target_sources()  to  add original source files will do
       exactly what would one expect, i.e.  the original source files would be  visible  in  IDE,
       and will not be built.

   INCLUDE_DIRECTORIES
       List of preprocessor include file search directories.

       This  property  holds a semicolon-separated list of paths and will be added to the list of
       include directories when this source file builds. These directories will  take  precedence
       over  directories  defined  at  target  level  except for Xcode generator due to technical
       limitations.

       Relative paths should not be added to this property directly.

       Contents of INCLUDE_DIRECTORIES may use “generator expressions” with  the  syntax  $<...>.
       See  the  cmake-generator-expressions(7) manual for available expressions.  However, Xcode
       does not support per-config per-source settings, so expressions that depend on  the  build
       configuration are not allowed with that generator.

   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 (i.e.  C++), C, CSharp, CUDA, Fortran, and ASM.  Setting  this  property  for  a  file
       means this file will be compiled.  Do not set this for headers or files that should not be
       compiled.

   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 Application Bundle (MACOSX_BUNDLE),  Core  Foundation  Bundle
       (BUNDLE), or Framework Bundle (FRAMEWORK).  It is applicable for macOS and iOS.

       Executable  targets  with  the  MACOSX_BUNDLE  property  set  are  built  as  macOS or iOS
       application bundles on  Apple  platforms.   Shared  library  targets  with  the  FRAMEWORK
       property  set  are  built  as  macOS or iOS frameworks on Apple platforms.  Module library
       targets with the BUNDLE property  set  are  built  as  macOS  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  macOS  Application  Bundles  the  content  folder  is <name>.app/Contents.  For macOS
       Frameworks the content folder is <name>.framework/Versions/<version>.  For macOS CFBundles
       the  content  folder is <name>.bundle/Contents (unless the extension is changed).  See the
       PUBLIC_HEADER, PRIVATE_HEADER, and RESOURCE target properties for specifying  files  meant
       for Headers, PrivateHeaders, or Resources directories.

       If  the  specified location is equal to Resources, the resulting location will be the same
       as if the RESOURCE property had been used. If the specified location is  a  sub-folder  of
       Resources,  it  will  be placed into the respective sub-folder. Note: For iOS Apple uses a
       flat bundle layout where no Resources folder exist. Therefore CMake strips  the  Resources
       folder name from the specified location.

   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.  On Makefile Generators and the Ninja generator  an
       object  file will be recompiled if any of the named files is newer than it.  Visual Studio
       Generators and the Xcode generator cannot implement such compilation dependencies.

       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
       purpose, 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 Ninja or Makefile Generators rule.

       Additional outputs created by compilation of this source file.  If any of these outputs is
       missing  the  object will be recompiled.  This is supported only on the Ninja and Makefile
       Generators and will be ignored on other generators.

   SKIP_AUTOGEN
       Exclude the source file from AUTOMOC, AUTOUIC and AUTORCC processing (for Qt projects).

       For finer exclusion control see SKIP_AUTOMOC, SKIP_AUTOUIC and SKIP_AUTORCC.

   EXAMPLE
          # ...
          set_property(SOURCE file.h PROPERTY SKIP_AUTOGEN ON)
          # ...

   SKIP_AUTOMOC
       Exclude the source file from AUTOMOC processing (for Qt projects).

       For broader exclusion control see SKIP_AUTOGEN.

   EXAMPLE
          # ...
          set_property(SOURCE file.h PROPERTY SKIP_AUTOMOC ON)
          # ...

   SKIP_AUTORCC
       Exclude the source file from AUTORCC processing (for Qt projects).

       For broader exclusion control see SKIP_AUTOGEN.

   EXAMPLE
          # ...
          set_property(SOURCE file.qrc PROPERTY SKIP_AUTORCC ON)
          # ...

   SKIP_AUTOUIC
       Exclude the source file from AUTOUIC processing (for Qt projects).

       SKIP_AUTOUIC can be set on C++ header and source files and on .ui files.

       For broader exclusion control see SKIP_AUTOGEN.

   EXAMPLE
          # ...
          set_property(SOURCE file.h PROPERTY SKIP_AUTOUIC ON)
          set_property(SOURCE file.cpp PROPERTY SKIP_AUTOUIC ON)
          set_property(SOURCE widget.ui PROPERTY SKIP_AUTOUIC ON)
          # ...

   SKIP_PRECOMPILE_HEADERS
       Is this source file skipped by PRECOMPILE_HEADERS feature.

       This property  helps  with  build  problems  that  one  would  run  into  when  using  the
       PRECOMPILE_HEADERS feature.

       One  example  would be the usage of Objective-C (.m) files, and Objective-C++ (.mm) files,
       which lead to compilation failure because they are treated (in case of  Ninja  /  Makefile
       generator)  as  C, and CXX respectively. The precompile headers are not compatible between
       languages.

   SKIP_UNITY_BUILD_INCLUSION
       Setting this property to true ensures the source file will be skipped by unity builds when
       its  associated  target  has  its  UNITY_BUILD property set to true.  The source file will
       instead be compiled on its own in the same way as it would with unity builds disabled.

       This property helps with “ODR (One definition rule)” problems where combining a particular
       source file with others might lead to build errors or other unintended side effects.

   Swift_DEPENDENCIES_FILE
       This  property sets the path for the Swift dependency file (swiftdeps) for the source.  If
       one is not specified, it will default to <OBJECT>.swiftdeps.

   Swift_DIAGNOSTICS_FILE
       This property controls where the Swift diagnostics are serialized.

   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.

   VS_COPY_TO_OUT_DIR
       Sets  the  <CopyToOutputDirectory>  tag for a source file in a Visual Studio project file.
       Valid values are Never, Always and PreserveNewest.

   VS_CSHARP_<tagname>
       Visual Studio and CSharp source-file-specific configuration.

       Tell the Visual Studio generators to set the source file tag <tagname> to a given value in
       the  generated  Visual  Studio  CSharp project. Ignored on other generators and languages.
       This property can be used to define dependencies between source files  or  set  any  other
       Visual Studio specific parameters.

       Example usage:

          set_source_files_property(<filename>
                   PROPERTIES
                   VS_CSHARP_DependentUpon <other file>
                   VS_CSHARP_SubType "Form")

   VS_DEPLOYMENT_CONTENT
       Mark  a  source  file  as  content  for  deployment  with a Windows Phone or Windows Store
       application when built with a Visual Studio generators.  The value must evaluate to either
       1  or  0  and  may  use  generator  expressions  to  make  the  choice  based on the build
       configuration.  The .vcxproj file  entry  for  the  source  file  will  be  marked  either
       DeploymentContent or ExcludedFromBuild for values 1 and 0, respectively.

   VS_DEPLOYMENT_LOCATION
       Specifies  the  deployment  location  for  a  content  source file with a Windows Phone or
       Windows Store application when built with a Visual Studio generators.   This  property  is
       only  applicable  when using VS_DEPLOYMENT_CONTENT.  The value represent the path relative
       to the app package and applies to all configurations.

   VS_INCLUDE_IN_VSIX
       Boolean property to specify if the file should be included within a  VSIX  (Visual  Studio
       Integration Extension) extension package.  This is needed for development of Visual Studio
       extensions.

   VS_RESOURCE_GENERATOR
       This property allows to specify the resource  generator  to  be  used  on  this  file.  It
       defaults to PublicResXFileCodeGenerator if not set.

       This property only applies to C# projects.

   VS_SHADER_DISABLE_OPTIMIZATIONS
       Disable  compiler  optimizations  for an .hlsl source file.  This adds the -Od flag to the
       command line for the FxCompiler tool.  Specify the value true for this property to disable
       compiler optimizations.

   VS_SHADER_ENABLE_DEBUG
       Enable  debugging  information  for  an  .hlsl source file.  This adds the -Zi flag to the
       command line for the FxCompiler tool.   Specify  the  value  true  to  generate  debugging
       information for the compiled shader.

   VS_SHADER_ENTRYPOINT
       Specifies the name of the entry point for the shader of a .hlsl source file.

   VS_SHADER_FLAGS
       Set additional Visual Studio shader flags of a .hlsl source file.

   VS_SHADER_MODEL
       Specifies the shader model of a .hlsl source file. Some shader types can only be used with
       recent shader models

   VS_SHADER_OBJECT_FILE_NAME
       Specifies a file name for the compiled shader object file for an .hlsl source file.   This
       adds the -Fo flag to the command line for the FxCompiler tool.

   VS_SHADER_OUTPUT_HEADER_FILE
       Set filename for output header file containing object code of a .hlsl source file.

   VS_SHADER_TYPE
       Set the Visual Studio shader type of a .hlsl source file.

   VS_SHADER_VARIABLE_NAME
       Set name of variable in header file containing object code of a .hlsl source file.

   VS_TOOL_OVERRIDE
       Override the default Visual Studio tool that will be applied to the source file with a new
       tool not based on the extension of the file.

   VS_XAML_TYPE
       Mark a Extensible Application Markup Language (XAML) source file as a different type  than
       the  default  Page.   The  most  common usage would be to set the default App.xaml file as
       ApplicationDefinition.

   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, using SWIG.  If WRAP_EXCLUDE is
       set to True, that indicates that this source file should not be wrapped.

   XCODE_EXPLICIT_FILE_TYPE
       Set the Xcode explicitFileType attribute  on  its  reference  to  a  source  file.   CMake
       computes a default based on file extension but can be told explicitly with this property.

       See also XCODE_LAST_KNOWN_FILE_TYPE.

   XCODE_FILE_ATTRIBUTES
       Add values to the Xcode ATTRIBUTES setting on its reference to a source file.  Among other
       things, this can be used to set the role on a .mig file:

          set_source_files_properties(defs.mig
              PROPERTIES
                  XCODE_FILE_ATTRIBUTES "Client;Server"
          )

   XCODE_LAST_KNOWN_FILE_TYPE
       Set the Xcode lastKnownFileType attribute on  its  reference  to  a  source  file.   CMake
       computes a default based on file extension but can be told explicitly with this property.

       See also XCODE_EXPLICIT_FILE_TYPE, which is preferred over this property if set.

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 considered 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
       convenience 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.   Setting  this  property  always
       sets the value without checking, so use with care.

PROPERTIES ON INSTALLED FILES

   CPACK_DESKTOP_SHORTCUTS
       Species a list of shortcut names that should be created on the Desktop for this file.

       The property is currently only supported by the CPack WIX Generator.

       The property is currently only supported by the CPack WIX Generator.

   CPACK_START_MENU_SHORTCUTS
       Species a list of shortcut names that should be created in the Start Menu for this file.

       The property is currently only supported by the CPack WIX Generator.

   CPACK_STARTUP_SHORTCUTS
       Species  a  list  of  shortcut names that should be created in the Startup folder for this
       file.

       The property is currently only supported by the CPack WIX Generator.

   CPACK_WIX_ACL
       Specifies access permissions for files or directories installed by a WiX installer.

       The property can contain multiple list entries, each of which has to match  the  following
       format.

          <user>[@<domain>]=<permission>[,<permission>]

       <user> and <domain> specify the windows user and domain for which the <Permission> element
       should be generated.

       <permission> is any of the YesNoType attributes listed here:

          http://wixtoolset.org/documentation/manual/v3/xsd/wix/permission.html

       The property is currently only supported by the CPack WIX Generator.

DEPRECATED PROPERTIES ON DIRECTORIES

   ADDITIONAL_MAKE_CLEAN_FILES
       Deprecated since version 3.15: Use ADDITIONAL_CLEAN_FILES instead.

       Additional files to remove during the clean stage.

       A ;-list of files that will be removed as a part of the make clean target.

       Arguments to ADDITIONAL_MAKE_CLEAN_FILES may use generator expressions.

       This property only works for the Makefile generators.  It is ignored on other generators.

   COMPILE_DEFINITIONS_<CONFIG>
       Ignored.  See CMake Policy CMP0043.

       Per-configuration preprocessor definitions in a directory.

       This is the configuration-specific version of COMPILE_DEFINITIONS  where  <CONFIG>  is  an
       upper-case name (ex. COMPILE_DEFINITIONS_DEBUG).

       This  property  will  be  initialized  in  each  directory by its value in the directory’s
       parent.

       Contents of COMPILE_DEFINITIONS_<CONFIG> may use “generator expressions” with  the  syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       Generator expressions should be preferred instead of setting this property.

   TEST_INCLUDE_FILE
       Deprecated.  Use TEST_INCLUDE_FILES instead.

       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.

DEPRECATED PROPERTIES ON TARGETS

   COMPILE_DEFINITIONS_<CONFIG>
       Ignored.  See CMake Policy CMP0043.

       Per-configuration preprocessor definitions on a target.

       This  is  the  configuration-specific  version of COMPILE_DEFINITIONS where <CONFIG> is an
       upper-case name (ex. COMPILE_DEFINITIONS_DEBUG).

       Contents of COMPILE_DEFINITIONS_<CONFIG> may use “generator expressions” with  the  syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       Generator expressions should be preferred instead of setting this property.

   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.

   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.

DEPRECATED PROPERTIES ON SOURCE FILES

   COMPILE_DEFINITIONS_<CONFIG>
       Ignored.  See CMake Policy CMP0043.

       Per-configuration preprocessor definitions on a source file.

       This is the configuration-specific version of COMPILE_DEFINITIONS.  Note that  Xcode  does
       not  support  per-configuration  source file flags so this property will be ignored by the
       Xcode generator.
