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 <#policy:CMP0002>). This is necessary to generate meaningful project file names in Xcode
<#generator:Xcode> and Visual Studio Generators <#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() <#command:add_custom_target>
names. For projects that care only about Makefile Generators <#makefile-generators> and do not wish to
support Xcode <#generator:Xcode> or Visual Studio Generators <#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: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
Added in version 3.9.

Name of the source_group() <#command:source_group> for AUTOMOC <#prop_tgt:AUTOMOC>, AUTORCC <#
prop_tgt:AUTORCC> and AUTOUIC <#prop_tgt:AUTOUIC> generated files.

Files generated by AUTOMOC <#prop_tgt:AUTOMOC>, AUTORCC <#prop_tgt:AUTORCC> and AUTOUIC <#
prop_tgt:AUTOUIC> are not always known at configure time and therefore can't be passed to source_group()
<#command:source_group>. AUTOGEN_SOURCE_GROUP can be used instead to generate or select a source group
for AUTOMOC <#prop_tgt:AUTOMOC>, AUTORCC <#prop_tgt:AUTORCC> and AUTOUIC <#prop_tgt:AUTOUIC> generated
files.

For AUTOMOC <#prop_tgt:AUTOMOC>, AUTORCC <#prop_tgt:AUTORCC> and AUTOUIC <#prop_tgt:AUTOUIC> specific
overrides see AUTOMOC_SOURCE_GROUP <#prop_gbl:AUTOMOC_SOURCE_GROUP>, AUTORCC_SOURCE_GROUP <#
prop_gbl:AUTORCC_SOURCE_GROUP> and AUTOUIC_SOURCE_GROUP <#prop_gbl:AUTOUIC_SOURCE_GROUP> respectively.

AUTOGEN_TARGETS_FOLDER
Name of FOLDER <#prop_tgt:FOLDER> for *_autogen targets that are added automatically by CMake for targets
for which AUTOMOC <#prop_tgt:AUTOMOC> is enabled.

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

AUTOMOC_SOURCE_GROUP
Added in version 3.9.

Name of the source_group() <#command:source_group> for AUTOMOC <#prop_tgt:AUTOMOC> generated files.

When set this is used instead of AUTOGEN_SOURCE_GROUP <#prop_gbl:AUTOGEN_SOURCE_GROUP> for files
generated by AUTOMOC <#prop_tgt:AUTOMOC>.

AUTOMOC_TARGETS_FOLDER
Name of FOLDER <#prop_tgt:FOLDER> for *_autogen targets that are added automatically by CMake for targets
for which AUTOMOC <#prop_tgt:AUTOMOC> is enabled.

This property is obsolete. Use AUTOGEN_TARGETS_FOLDER <#prop_gbl:AUTOGEN_TARGETS_FOLDER> instead.

AUTORCC_SOURCE_GROUP
Added in version 3.9.

Name of the source_group() <#command:source_group> for AUTORCC <#prop_tgt:AUTORCC> generated files.

When set this is used instead of AUTOGEN_SOURCE_GROUP <#prop_gbl:AUTOGEN_SOURCE_GROUP> for files
generated by AUTORCC <#prop_tgt:AUTORCC>.

AUTOUIC_SOURCE_GROUP
Added in version 3.21.

Name of the source_group() <#command:source_group> for AUTOUIC <#prop_tgt:AUTOUIC> generated files.

When set this is used instead of AUTOGEN_SOURCE_GROUP <#prop_gbl:AUTOGEN_SOURCE_GROUP> for files
generated by AUTOUIC <#prop_tgt:AUTOUIC>.

CMAKE_C_KNOWN_FEATURES
Added in version 3.1.

List of C features known to this version of CMake.

The features listed in this global property may be known to be available to the C compiler. If the
feature is available with the C compiler, it will be listed in the CMAKE_C_COMPILE_FEATURES <#
variable:CMAKE_C_COMPILE_FEATURES> variable.

The features listed here may be used with the target_compile_features() <#
command:target_compile_features> command. See the cmake-compile-features(7) <#
manual:cmake-compile-features(7)> manual for information on compile features and a list of supported
compilers.

The features known to this version of CMake are listed below.

Note:
If the compiler's default standard level is at least that of the requested feature, CMake may omit the
-std= flag. The flag may still be added if the compiler's default extensions mode does not match the
<LANG>_EXTENSIONS <#prop_tgt:<LANG>_EXTENSIONS> target property, or if the <LANG>_STANDARD <#
prop_tgt:<LANG>_STANDARD> target property is set.

Added in version 3.17.

List of CUDA features known to this version of CMake.

The features listed in this global property may be known to be available to the CUDA compiler. If the
feature is available with the C++ compiler, it will be listed in the CMAKE_CUDA_COMPILE_FEATURES <#
variable:CMAKE_CUDA_COMPILE_FEATURES> variable.

Added in version 3.1.

List of C++ features known to this version of CMake.

The features listed in this global property may be known to be available to the C++ compiler. If the
feature is available with the C++ compiler, it will be listed in the CMAKE_CXX_COMPILE_FEATURES <#
variable:CMAKE_CXX_COMPILE_FEATURES> variable.

The features known to this version of CMake are listed below.

High level meta features indicating C++ standard support
Added in version 3.8.

The following meta features indicate general support for the associated language standard. It reflects
the language support claimed by the compiler, but it does not necessarily imply complete conformance to
that standard.

cxx_std_98

Low level individual compile features
For C++ 11 and C++ 14, compilers were sometimes slow to implement certain language features. CMake
provided some individual compile features to help projects determine whether specific features were
available. These individual features are now less relevant and projects should generally prefer to use
the high level meta features instead. Individual compile features are not provided for C++ 17 or later.

See the cmake-compile-features(7) <#manual:cmake-compile-features(7)> manual for further discussion of
the use of individual compile features.

CMAKE_ROLE
Added in version 3.14.

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: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: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.

ECLIPSE_EXTRA_CPROJECT_CONTENTS
Added in version 3.12.

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 <#prop_gbl:ECLIPSE_EXTRA_NATURES> 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 <#prop_gbl:ECLIPSE_EXTRA_CPROJECT_CONTENTS> property.

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
Added in version 3.7.

Whether the find_library() <#command:find_library> command should automatically search lib32 directories.

FIND_LIBRARY_USE_LIB32_PATHS is a boolean specifying whether the find_library() <#command: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:CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX>
variable.

FIND_LIBRARY_USE_LIB64_PATHS
Whether find_library() <#command:find_library> should automatically search lib64 directories.

FIND_LIBRARY_USE_LIB64_PATHS is a boolean specifying whether the find_library() <#command: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:CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX>
variable.

FIND_LIBRARY_USE_LIBX32_PATHS
Added in version 3.9.

Whether the find_library() <#command:find_library> command should automatically search libx32
directories.

FIND_LIBRARY_USE_LIBX32_PATHS is a boolean specifying whether the find_library() <#command: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:CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX>
variable.

FIND_LIBRARY_USE_OPENBSD_VERSIONING
Whether find_library() <#command:find_library> should find OpenBSD-style shared libraries.

This property is a boolean specifying whether the find_library() <#command: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
Added in version 3.9.

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

True when using a multi-configuration generator such as:

• Ninja Multi-Config <#generator:Ninja Multi-Config>

• Visual Studio Generators <#visual-studio-generators>

• Xcode <#generator:Xcode>

Multi-config generators use CMAKE_CONFIGURATION_TYPES <#variable:CMAKE_CONFIGURATION_TYPES> as the set of
configurations and ignore CMAKE_BUILD_TYPE <#variable: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.

INSTALL_PARALLEL
Added in version 3.30.

Enables parallel installation option for a project. The install code for each subdirectory added with
add_subdirectory can run independently.

When using the Ninja generator, setting this property to ON, causes install/local targets have the
console pool disabled, allowing them to run concurrently.

This property also provides the target install/parallel, which has an explicit dependency on the
install/local target for each subdirectory.
Added in version 3.31.

When this property is ON, cmake --install can be given the -j <jobs> or --parallel <jobs> option to
specify a maximum number of jobs. The CMAKE_INSTALL_PARALLEL_LEVEL <#
envvar:CMAKE_INSTALL_PARALLEL_LEVEL> environment variable specifies a default parallel level if this
option is not provided.

Calls to install(CODE) <#code> or install(SCRIPT) <#script> might depend on actions performed by an
earlier install() <#command:install> command in a different directory such as files installed or variable
settings. If the project has such order-dependent installation logic, parallel installation should be not
be enabled, in order to prevent possible race conditions.

IN_TRY_COMPILE
Read-only property that is true during a try-compile configuration.

True when building a project inside a try_compile() <#command:try_compile> or try_run() <#
command:try_run> command.

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 <#variable:CMAKE_JOB_POOL_COMPILE>
and CMAKE_JOB_POOL_LINK <#variable:CMAKE_JOB_POOL_LINK> or per target by setting the target properties
JOB_POOL_COMPILE <#prop_tgt:JOB_POOL_COMPILE> and JOB_POOL_LINK <#prop_tgt:JOB_POOL_LINK>. Custom
commands <#command:add_custom_command> and custom targets <#command:add_custom_target> 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: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.

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

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

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

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

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

If not set, CMake uses "CMakePredefinedTargets" as a default value for this property. Targets such as
INSTALL, PACKAGE and RUN_TESTS will be organized into this FOLDER. See also the documentation for the
FOLDER <#prop_tgt:FOLDER> target property.

PROPAGATE_TOP_LEVEL_INCLUDES_TO_TRY_COMPILE
Added in version 3.30.

When this global property is set to true, the CMAKE_PROJECT_TOP_LEVEL_INCLUDES <#
variable:CMAKE_PROJECT_TOP_LEVEL_INCLUDES> variable is propagated into try_compile() <#
command:try_compile> calls that use the whole-project signature <#try-compiling-whole-projects>. Calls
to the source file signature <#try-compiling-source-files> are not affected by this property.
PROPAGATE_TOP_LEVEL_INCLUDES_TO_TRY_COMPILE is unset by default.

For dependency providers <#dependency-providers-overview> that want to be enabled in whole-project
try_compile() <#command:try_compile> calls, set this global property to true just before or after
registering the provider. Note that all files listed in CMAKE_PROJECT_TOP_LEVEL_INCLUDES <#
variable:CMAKE_PROJECT_TOP_LEVEL_INCLUDES> will need to be able to handle being included in such
try_compile() <#command:try_compile> calls, and it is the user's responsibility to ensure this.

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.

Note:
This property is intended for internal use by ctest(1) <#manual:ctest(1)>. Projects and developers
should use the <LANG>_COMPILER_LAUNCHER <#prop_tgt:<LANG>_COMPILER_LAUNCHER> target properties or the
associated CMAKE_<LANG>_COMPILER_LAUNCHER <#variable:CMAKE_<LANG>_COMPILER_LAUNCHER> variables
instead.

Makefile Generators <#makefile-generators> and the Ninja <#generator: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 <#makefile-generators> and the Ninja <#generator: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.

Note:
This property is intended for internal use by ctest(1) <#manual:ctest(1)>. Projects and developers
should use the <LANG>_LINKER_LAUNCHER <#prop_tgt:<LANG>_LINKER_LAUNCHER> target properties or the
associated CMAKE_<LANG>_LINKER_LAUNCHER <#variable:CMAKE_<LANG>_LINKER_LAUNCHER> variables instead.

Makefile Generators <#makefile-generators> and the Ninja <#generator: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 <#variable: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
Added in version 3.4.

Specify whether to report the completion of each target.

This property specifies whether Makefile Generators <#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 <#prop_gbl: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 purpose OS do so, the exceptions are usually embedded systems
with no or special OSs.

USE_FOLDERS
Controls whether to use the FOLDER <#prop_tgt:FOLDER> target property to organize targets into folders.
The value of USE_FOLDERS at the end of the top level CMakeLists.txt file is what determines the behavior.

Changed in version 3.26: CMake treats this property as ON by default. See policy CMP0143 <#
policy:CMP0143>.

Not all CMake generators support recording folder details for targets. The Xcode <#generator:Xcode> and
Visual Studio <#visual-studio-generators> generators are examples of generators that do. Similarly, not
all IDEs support presenting targets using folder hierarchies, even if the CMake generator used provides
the necessary information.

XCODE_EMIT_EFFECTIVE_PLATFORM_NAME
Added in version 3.8.

Control emission of EFFECTIVE_PLATFORM_NAME by the Xcode <#generator: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: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, visionOS, 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 <#manual:cmake-generator-expressions(7)> like TARGET_FILE and will
render those mostly unusable.

PROPERTIES ON DIRECTORIES

   ADDITIONAL_CLEAN_FILES
       Added in version 3.15.

       A ;-list <#cmake-language-lists> 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 <#
       prop_tgt: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      <#
       manual:cmake-generator-expressions(7)>.

       This property only works for the Ninja <#generator:Ninja> and the Makefile generators.  It is ignored  by
       other generators.

   BINARY_DIR
       Added in version 3.7.

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

   BUILDSYSTEM_TARGETS
       Added in version 3.7.

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

       See also the IMPORTED_TARGETS <#prop_dir:IMPORTED_TARGETS> directory property.

   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  <#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()  <#
       command:add_compile_definitions> (or add_definitions() <#command: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.

       Added in version 3.26: Any leading -D on an item will be removed.

       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:cmake-generator-expressions(7)> manual for available expressions.
       See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)>  manual  for  more  on  defining  buildsystem
       properties.

       The  corresponding  COMPILE_DEFINITIONS_<CONFIG> <#prop_dir: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 <#cmake-language-lists> of options given so far to the
       add_compile_options() <#command:add_compile_options> command.

       This property is used to initialize the COMPILE_OPTIONS <#prop_tgt: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:cmake-generator-expressions(7)> manual for available expressions.
       See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)>  manual  for  more  on  defining  buildsystem
       properties.

   DEFINITIONS
       For CMake 2.4 compatibility only.  Use COMPILE_DEFINITIONS <#prop_dir:COMPILE_DEFINITIONS> instead.

       This  read-only  property  specifies  the  list  of  flags  given  so  far  to  the  add_definitions() <#
       command:add_definitions> command.  It is intended for debugging purposes.  Use the COMPILE_DEFINITIONS <#
       prop_dir:COMPILE_DEFINITIONS> directory property instead.

       This built-in read-only property does not exist if policy CMP0059 <#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.

       EXCLUDE_FROM_ALL  is  meant  for  when  the  subdirectory contains a separate part of the project that is
       useful, but not necessary, such as a set of examples, or e.g. an integrated 3rd party library.  Typically
       the subdirectory should contain its own project() <#command:project> command invocation so  that  a  full
       build  system  will  be  generated in the subdirectory (such as a Visual Studio IDE solution file).  Note
       that inter-target dependencies supersede this exclusion.  If a target built by the parent project depends
       on a target in the subdirectory, the dependee target will be included in the parent project build  system
       to satisfy the dependency.

       If the EXCLUDE_FROM_ALL argument is provided, it has the following effects:

       • Targets  defined  in  the  subdirectory  or  below will not be included in the ALL target of the parent
         directory.  Those targets must be built explicitly by the user, or be a dependency  of  another  target
         that will be built.

       • Targets defined in the subdirectory or below will be excluded from IDE project files.

       • Any  install  rules  defined  in  the  subdirectory or below will be ignored when installing the parent
         directory.

       Note that these effects are not the same as those for the  EXCLUDE_FROM_ALL  <#prop_tgt:EXCLUDE_FROM_ALL>
       target property.

   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.

   IMPORTED_TARGETS
       Added in version 3.21.

       This read-only directory property contains a semicolon-separated list <#cmake-language-lists> of Imported
       Targets  <#imported-targets>  added in the directory by calls to the add_library() <#command:add_library>
       and add_executable() <#command:add_executable> commands.  Each entry in the list is the logical name of a
       target, suitable to pass to the get_property() <#command:get_property> command TARGET option when  called
       in the same directory.

       See also the BUILDSYSTEM_TARGETS <#prop_dir:BUILDSYSTEM_TARGETS> directory property.

   INCLUDE_DIRECTORIES
       List of preprocessor include file search directories.

       This  property  specifies  the  list  of  directories  given  so  far  to  the  include_directories()  <#
       command:include_directories> command.

       This  property  is  used  to  populate  the  INCLUDE_DIRECTORIES  <#prop_tgt: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:set_property> command, and can  be  set  on  the  current  directory  using  the
       set_directory_properties()  <#command: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  <#
       prop_tgt: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:include_directories>
       command.     Calls   to   set_property()   <#command:set_property>   or   set_directory_properties()   <#
       command: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()
       <#command:add_executable> or add_library() <#command: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:cmake-generator-expressions(7)> manual for available expressions.
       See  the  cmake-buildsystem(7)  <#manual: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:include_regular_expression>
       command for a high-level interface to set this property.

   LABELS
       Added in version 3.10.

       Specify a list of text labels associated with  a  directory  and  all  of  its  subdirectories.  This  is
       equivalent  to  setting  the LABELS <#prop_tgt:LABELS> target property and the LABELS <#prop_test: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: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 <#cmake-language-lists> of directories  and  is  typically
       populated  using  the  link_directories() <#command: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  <#prop_tgt: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:cmake-generator-expressions(7)> manual for available expressions.
       See  the  cmake-buildsystem(7)  <#manual:cmake-buildsystem(7)>  manual  for  more on defining buildsystem
       properties.

   LINK_OPTIONS
       Added in version 3.13.

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

       This  property  holds  a  semicolon-separated list <#cmake-language-lists> of options given so far to the
       add_link_options() <#command:add_link_options> command.

       This property is used to initialize the LINK_OPTIONS  <#prop_tgt: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:cmake-generator-expressions(7)> manual for available expressions.
       See the cmake-buildsystem(7) <#manual: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: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: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.

       Note:
          This  property  is  intended for internal use by ctest(1) <#manual:ctest(1)>.  Projects and developers
          should use the <LANG>_COMPILER_LAUNCHER <#prop_tgt:<LANG>_COMPILER_LAUNCHER> target properties or  the
          associated    CMAKE_<LANG>_COMPILER_LAUNCHER    <#variable:CMAKE_<LANG>_COMPILER_LAUNCHER>   variables
          instead.

       See the global property <#prop_gbl:RULE_LAUNCH_COMPILE> 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.

       Note:
          This  property  is  intended for internal use by ctest(1) <#manual:ctest(1)>.  Projects and developers
          should use the <LANG>_LINKER_LAUNCHER  <#prop_tgt:<LANG>_LINKER_LAUNCHER>  target  properties  or  the
          associated CMAKE_<LANG>_LINKER_LAUNCHER <#variable:CMAKE_<LANG>_LINKER_LAUNCHER> variables instead.

       See  the  global  property <#prop_gbl:RULE_LAUNCH_LINK> of the same name for details.  This overrides the
       global property for a directory.

   SOURCE_DIR
       Added in version 3.7.

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

   SUBDIRECTORIES
       Added in version 3.7.

       This  read-only  directory  property  contains  a  semicolon-separated  list  <#cmake-language-lists>  of
       subdirectories  processed  so  far  by the add_subdirectory() <#command:add_subdirectory> or subdirs() <#
       command: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:get_property> command
       DIRECTORY option.

       Note:
          The subdirs() <#command: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.

   SYSTEM
       Added in version 3.25.

       This directory property  is  used  to  initialize  the  SYSTEM  <#prop_tgt:SYSTEM>  target  property  for
       non-imported   targets  created  in  that  directory.   It  is  set  to  true  by  add_subdirectory()  <#
       command:add_subdirectory> and  FetchContent_Declare()  <#command:fetchcontent_declare>  when  the  SYSTEM
       option is given as an argument to those commands.

   TESTS
       Added in version 3.12.

       List of tests.

       This read-only property holds a semicolon-separated list <#cmake-language-lists> of tests defined so far,
       in the current directory, by the add_test() <#command:add_test> command.

   TEST_INCLUDE_FILES
       Added in version 3.10.

       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 Generators <#visual-studio-generators>; it is ignored on other
       generators.   The property only applies when set on a directory whose CMakeLists.txt contains a project()
       <#command: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 Generators <#visual-studio-generators>; it is ignored on other
       generators.  The property only applies when set on a directory whose CMakeLists.txt contains a  project()
       <#command:project> command.

   VS_STARTUP_PROJECT
       Added in version 3.6.

       Specify the default startup project in a Visual Studio solution.

       The  Visual  Studio  Generators  <#visual-studio-generators>  create a .sln file for each directory whose
       CMakeLists.txt file calls the project() <#command:project>  command.   Set  this  property  in  the  same
       directory  as  a project() <#command: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
Added in version 3.15.

A ;-list <#cmake-language-lists> 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 <#prop_dir: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 <#
manual:cmake-generator-expressions(7)>.

This property only works for the Ninja <#generator:Ninja> and the Makefile generators. It is ignored by
other generators.

AIX_EXPORT_ALL_SYMBOLS
Added in version 3.17.

On AIX, CMake automatically exports all symbols from shared libraries, and from executables with the
ENABLE_EXPORTS <#prop_tgt:ENABLE_EXPORTS> target property set. Explicitly disable this boolean property
to suppress the behavior and export no symbols by default. In this case it is expected that the project
will use other means to export some symbols.

This property is initialized by the value of the CMAKE_AIX_EXPORT_ALL_SYMBOLS <#
variable:CMAKE_AIX_EXPORT_ALL_SYMBOLS> variable if it is set when a target is created.

AIX_SHARED_LIBRARY_ARCHIVE
Added in version 3.31.

On AIX, enable creation of a shared library archive. This places the shared object .so file inside an
archive .a file.

By default, CMake creates shared libraries on AIX as plain shared object .so files for consistency with
other UNIX platforms. Alternatively, set this property to a true value to create a shared library
archive instead, as is AIX convention.

The shared object name in the archive encodes version information from the SOVERSION <#
prop_tgt:SOVERSION> target property, if set, and otherwise from the VERSION <#prop_tgt:VERSION> target
property, if set.

This property defaults to CMAKE_AIX_SHARED_LIBRARY_ARCHIVE <#variable:CMAKE_AIX_SHARED_LIBRARY_ARCHIVE>
if that variable is set when a non-imported SHARED library target is created by add_library() <#
command:add_library>. Imported targets must explicitly enable AIX_SHARED_LIBRARY_ARCHIVE if they import
an AIX shared library archive.

ALIAS_GLOBAL
Added in version 3.18.

Read-only property indicating of whether an ALIAS target <#alias-targets> is globally visible.

The boolean value of this property is TRUE for aliases to IMPORTED targets <#imported-targets> created
with the GLOBAL options to add_executable() <#command:add_executable> or add_library() <#
command:add_library>, FALSE otherwise. It is undefined for targets built within the project.

Note:
Promoting an IMPORTED target <#imported-targets> from LOCAL to GLOBAL scope by changing the value or
IMPORTED_GLOBAL <#prop_tgt:IMPORTED_GLOBAL> target property do not change the scope of local aliases.

ALIASED_TARGET
Name of target aliased by this target.

If this is an Alias Target <#alias-targets>, this property contains the name of the target aliased.

ANDROID_ANT_ADDITIONAL_OPTIONS
Added in version 3.4.

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:CMAKE_ANDROID_ANT_ADDITIONAL_OPTIONS> variable if it is
set when a target is created.

ANDROID_API
Added in version 3.1.

When Cross Compiling for Android with NVIDIA Nsight Tegra Visual Studio Edition <#
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:CMAKE_ANDROID_API> variable if
it is set when a target is created.

ANDROID_API_MIN
Added in version 3.2.

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:CMAKE_ANDROID_API_MIN>
variable if it is set when a target is created. Native code builds using this API version.

ANDROID_ARCH
Added in version 3.4.

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:CMAKE_ANDROID_ARCH>
variable if it is set when a target is created.

ANDROID_ASSETS_DIRECTORIES
Added in version 3.4.

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:CMAKE_ANDROID_ASSETS_DIRECTORIES> variable if it
is set when a target is created.

ANDROID_GUI
Added in version 3.1.

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: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:add_executable> command invocation to specify the root directory of the application package
source.

ANDROID_JAR_DEPENDENCIES
Added in version 3.4.

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:CMAKE_ANDROID_JAR_DEPENDENCIES> variable if it is set when a target is created.

ANDROID_JAR_DIRECTORIES
Added in version 3.4.

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: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:cmake-generator-expressions(7)> manual for available expressions.

ANDROID_JAVA_SOURCE_DIR
Added in version 3.4.

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:CMAKE_ANDROID_JAVA_SOURCE_DIR> variable if it is set when a
target is created.

ANDROID_NATIVE_LIB_DEPENDENCIES
Added in version 3.4.

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: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:cmake-generator-expressions(7)> manual for available
expressions.

ANDROID_NATIVE_LIB_DIRECTORIES
Added in version 3.4.

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: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:cmake-generator-expressions(7)> manual for available
expressions.

ANDROID_PROCESS_MAX
Added in version 3.4.

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:CMAKE_ANDROID_PROCESS_MAX> variable if it is set when a target is created.

ANDROID_PROGUARD
Added in version 3.4.

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:CMAKE_ANDROID_PROGUARD> variable if it is set when a target is created.

ANDROID_PROGUARD_CONFIG_PATH
Added in version 3.4.

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:CMAKE_ANDROID_PROGUARD_CONFIG_PATH> variable if it is set when a target is created.

ANDROID_SECURE_PROPS_PATH
Added in version 3.4.

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:CMAKE_ANDROID_SECURE_PROPS_PATH> variable if it is set when a
target is created.

This property is initialized by the value of the CMAKE_ANDROID_STL_TYPE <#
variable:CMAKE_ANDROID_STL_TYPE> variable if it is set when a target is created.

ARCHIVE_OUTPUT_DIRECTORY
Output directory in which to build ARCHIVE <#archive-output-artifacts> target files.

This property specifies the directory into which archive target files should be built. The property
value may use generator expressions <#manual:cmake-generator-expressions(7)>. Multi-configuration
generators (Visual Studio <#visual-studio-generators>, Xcode <#generator:Xcode>, Ninja Multi-Config <#
generator:Ninja Multi-Config>) 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_ARCHIVE_OUTPUT_DIRECTORY <#
variable:CMAKE_ARCHIVE_OUTPUT_DIRECTORY> variable if it is set when a target is created.

Note:
On macOS, this property will be ignored for the linker import files (e.g. .tbd files, see
ENABLE_EXPORTS <#prop_tgt:ENABLE_EXPORTS> property for details) when:

• The FRAMEWORK <#prop_tgt:FRAMEWORK> is set, because the framework layout cannot be changed.

• The Xcode <#generator:Xcode> generator is used, due to the limitations and constraints of the Xcode
tool.

In both cases, the linker import files will be generated in the same directory as the shared library.

See also the ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> <#prop_tgt:ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>> target
property.

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

This is a per-configuration version of the ARCHIVE_OUTPUT_DIRECTORY <#prop_tgt: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: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 <#
manual:cmake-generator-expressions(7)>.

ARCHIVE_OUTPUT_NAME
Output name for ARCHIVE <#archive-output-artifacts> target files.

This property specifies the base name for archive target files. It overrides OUTPUT_NAME <#
prop_tgt:OUTPUT_NAME> and OUTPUT_NAME_<CONFIG> <#prop_tgt:OUTPUT_NAME_<CONFIG>> properties.

Note:
On macOS, this property will be ignored for the linker import files (e.g. .tbd files, see
ENABLE_EXPORTS <#prop_tgt:ENABLE_EXPORTS> property for details) when:

• The FRAMEWORK <#prop_tgt:FRAMEWORK> is set, because the framework layout cannot be changed.

• The Xcode <#generator:Xcode> generator is used, due to the limitations and constraints of the Xcode
tool.

In both cases, the linker import files will be generated with the same name as the shared library.

See also the ARCHIVE_OUTPUT_NAME_<CONFIG> <#prop_tgt:ARCHIVE_OUTPUT_NAME_<CONFIG>> target property.

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

This is the configuration-specific version of the ARCHIVE_OUTPUT_NAME <#prop_tgt:ARCHIVE_OUTPUT_NAME>
target property.

AUTOGEN_BETTER_GRAPH_MULTI_CONFIG
Added in version 3.29.

AUTOGEN_BETTER_GRAPH_MULTI_CONFIG is a boolean property that can be set on a target to have better
dependency graph for multi-configuration generators. When this property is enabled, CMake will generate
more per-config targets. Thus, the dependency graph will be more accurate for multi-configuration
generators and some recompilations will be avoided.

If the Qt version is 6.8 or newer, this property is enabled by default. If the Qt version is older than
6.8, this property is disabled by default. Consult the Qt documentation to check if the property can be
enabled for older Qt versions.

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

This property is initialized by the CMAKE_AUTOGEN_BETTER_GRAPH_MULTI_CONFIG <#
variable:CMAKE_AUTOGEN_BETTER_GRAPH_MULTI_CONFIG> variable if it is set when a target is created.

AUTOGEN_BUILD_DIR
Added in version 3.9.

Directory where AUTOMOC <#prop_tgt:AUTOMOC>, AUTOUIC <#prop_tgt:AUTOUIC> and AUTORCC <#prop_tgt:AUTORCC>
generate files for the target.

The directory is created on demand and automatically added to the ADDITIONAL_CLEAN_FILES <#
prop_tgt:ADDITIONAL_CLEAN_FILES> target property.

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

By default AUTOGEN_BUILD_DIR is unset.

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

AUTOGEN_COMMAND_LINE_LENGTH_MAX
Added in version 3.29.

Command line length limit for autogen targets, i.e. moc or uic, that triggers the use of response files
on Windows instead of passing all arguments to the command line.

• An empty (or unset) value sets the limit to 32000

• A positive non zero integer value sets the exact command line length limit.

By default AUTOGEN_COMMAND_LINE_LENGTH_MAX is initialized from CMAKE_AUTOGEN_COMMAND_LINE_LENGTH_MAX <#
variable:CMAKE_AUTOGEN_COMMAND_LINE_LENGTH_MAX>.

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

AUTOGEN_ORIGIN_DEPENDS
Added in version 3.14.

Switch for forwarding origin target dependencies to the corresponding The <ORIGIN>_autogen target <#
origin-autogen> target.

Note:
If Qt 5.15 or later is used and the generator is either Ninja <#generator:Ninja> or Makefile
Generators <#makefile-generators>, origin target dependencies are forwarded to the The
<ORIGIN>_autogen_timestamp_deps target <#origin-autogen-timestamp-deps> target instead of The
<ORIGIN>_autogen target <#origin-autogen>

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

By default AUTOGEN_ORIGIN_DEPENDS is initialized from CMAKE_AUTOGEN_ORIGIN_DEPENDS <#
variable:CMAKE_AUTOGEN_ORIGIN_DEPENDS> which is ON by default.

In total the dependencies of the The <ORIGIN>_autogen target <#origin-autogen> target are composed from

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

• additional user defined dependencies from AUTOGEN_TARGET_DEPENDS <#prop_tgt:AUTOGEN_TARGET_DEPENDS>

See the cmake-qt(7) <#manual: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 The <ORIGIN>_autogen target <#origin-autogen> target only. This is especially interesting
when a global autogen target <#variable:CMAKE_GLOBAL_AUTOGEN_TARGET> is enabled.

When the The <ORIGIN>_autogen target <#origin-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 <#prop_tgt:AUTOGEN_TARGET_DEPENDS> to add missing dependencies.

AUTOGEN_PARALLEL
Added in version 3.11.

Number of parallel moc or uic processes to start when using AUTOMOC <#prop_tgt:AUTOMOC> and AUTOUIC <#
prop_tgt:AUTOUIC>.

The custom The <ORIGIN>_autogen target <#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 <#
variable:CMAKE_AUTOGEN_PARALLEL>.

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

AUTOGEN_TARGET_DEPENDS
Additional target dependencies of the corresponding The <ORIGIN>_autogen target <#origin-autogen> target.

Note:
If Qt 5.15 or later is used and the generator is either Ninja <#generator:Ninja> or Makefile
Generators <#makefile-generators>, additional target dependencies are added to the The
<ORIGIN>_autogen_timestamp_deps target <#origin-autogen-timestamp-deps> target instead of the The
<ORIGIN>_autogen target <#origin-autogen> target.

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

In total the dependencies of the The <ORIGIN>_autogen target <#origin-autogen> target are composed from

• forwarded origin target dependencies (enabled by default via AUTOGEN_ORIGIN_DEPENDS <#
prop_tgt:AUTOGEN_ORIGIN_DEPENDS>)

• additional user defined dependencies from AUTOGEN_TARGET_DEPENDS

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

Use cases
If AUTOMOC <#prop_tgt:AUTOMOC> or AUTOUIC <#prop_tgt:AUTOUIC> depends on a file that is either

• a GENERATED <#prop_sf:GENERATED> non C++ file (e.g. a GENERATED <#prop_sf:GENERATED> .json or .ui file)
or

• a GENERATED <#prop_sf:GENERATED> C++ file that isn't recognized by AUTOMOC <#prop_tgt:AUTOMOC> and
AUTOUIC <#prop_tgt:AUTOUIC> because it's skipped by SKIP_AUTOMOC <#prop_sf:SKIP_AUTOMOC>, SKIP_AUTOUIC
<#prop_sf:SKIP_AUTOUIC>, SKIP_AUTOGEN <#prop_sf:SKIP_AUTOGEN> or CMP0071 <#policy:CMP0071> or

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

it must be added to AUTOGEN_TARGET_DEPENDS.

AUTOGEN_USE_SYSTEM_INCLUDE
Added in version 3.27.

AUTOGEN_USE_SYSTEM_INCLUDE is a boolean property that can be set on a target to indicate that the autogen
target include directory should be added as a system include directory or normal include directory to the
target.

If this property is not set, the autogen target include directory is added as a system include directory
by default. See policy CMP0151 <#policy:CMP0151>.

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

This property is initialized by the CMAKE_AUTOGEN_USE_SYSTEM_INCLUDE <#
variable:CMAKE_AUTOGEN_USE_SYSTEM_INCLUDE> variable if it is set when a target is created.

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 commands like QT4_WRAP_CPP() <#module:FindQt4>, qt5_wrap_cpp() <https://doc.qt.io/
qt-5/qtcore-cmake-qt5-wrap-cpp.html>, etc. Currently, Qt versions 4 to 6 are supported.

This property is initialized by the value of the CMAKE_AUTOMOC <#variable: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 <#prop_tgt: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 <#
prop_tgt: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 <#prop_tgt: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 <#
prop_tgt: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 <#prop_gbl:GENERATOR_IS_MULTI_CONFIG>
generators.

Where <AUTOGEN_BUILD_DIR> is the value of the target property AUTOGEN_BUILD_DIR <#
prop_tgt:AUTOGEN_BUILD_DIR>.

The include directory is automatically added to the target's INCLUDE_DIRECTORIES <#
prop_tgt: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 <#
prop_gbl:GENERATOR_IS_MULTI_CONFIG> 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, or

• <AUTOGEN_BUILD_DIR>/mocs_compilation_$<CONFIG>.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[456]Core library, that
the target links to. To find the minor version, CMake builds a list of available Qt versions from

• Qt6Core_VERSION_MAJOR and Qt6Core_VERSION_MINOR variables (usually set by find_package(Qt6...))

• Qt6Core_VERSION_MAJOR and Qt6Core_VERSION_MINOR directory properties

• 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() <#command:add_executable> or add_library() <#command: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[456]...) call sets the QT/Qt[56]Core_VERSION_MAJOR/MINOR variables. If the call is in
a different context than the add_executable() <#command:add_executable> or add_library() <#
command: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[456]...) calling context to the add_executable() <#command:add_executable> or
add_library() <#command: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 <#prop_tgt:AUTOMOC_EXECUTABLE>: The moc executable will be detected automatically, but
can be forced to a certain binary using this target property.

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

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

AUTOMOC_DEPEND_FILTERS <#prop_tgt: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 <#prop_tgt: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 <#prop_sf:SKIP_AUTOMOC>: Sources and headers can be excluded from AUTOMOC processing by
setting this source file property.

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

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

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

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

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

AUTOGEN_COMMAND_LINE_LENGTH_MAX <#prop_tgt:AUTOGEN_COMMAND_LINE_LENGTH_MAX>: This target property
controls the limit when to use response files for moc or uic processes on Windows.

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

AUTOMOC_COMPILER_PREDEFINES
Added in version 3.10.

Boolean value used by AUTOMOC <#prop_tgt: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 <#variable:CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND> when

• AUTOMOC <#prop_tgt:AUTOMOC> is enabled,

• AUTOMOC_COMPILER_PREDEFINES is enabled,

• CMAKE_CXX_COMPILER_PREDEFINES_COMMAND <#variable:CMAKE_<LANG>_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 <#prop_tgt: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 <#
variable:CMAKE_AUTOMOC_COMPILER_PREDEFINES>, which is ON by default.

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

AUTOMOC_DEPEND_FILTERS
Added in version 3.9.

Filter definitions used by AUTOMOC <#prop_tgt: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 <#prop_tgt: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 <#prop_sf:GENERATED> or if it is not in the target's sources,
then it might be necessary to add it to the The <ORIGIN>_autogen target <#origin-autogen> target
dependencies. See AUTOGEN_TARGET_DEPENDS <#prop_tgt:AUTOGEN_TARGET_DEPENDS> for reference.

By default AUTOMOC_DEPEND_FILTERS is initialized from CMAKE_AUTOMOC_DEPEND_FILTERS <#
variable:CMAKE_AUTOMOC_DEPEND_FILTERS>, which is empty by default.

From Qt 5.15.0 on this variable is ignored as moc is able to output the correct dependencies.

See the cmake-qt(7) <#manual: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 <#
variable: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 <#prop_sf:GENERATED>) file that is listed in the target's
source. Therefore we do not need to add it to AUTOGEN_TARGET_DEPENDS <#prop_tgt: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 <#
prop_tgt:AUTOMOC>. We change this by adding JSON_BASED_CLASS to CMAKE_AUTOMOC_MACRO_NAMES <#
variable: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 <#variable: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 <#prop_sf:GENERATED> which is why we have to add it to
AUTOGEN_TARGET_DEPENDS <#prop_tgt:AUTOGEN_TARGET_DEPENDS>:

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

AUTOMOC_EXECUTABLE
Added in version 3.14.

AUTOMOC_EXECUTABLE is file path pointing to the moc executable to use for AUTOMOC <#prop_tgt: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:cmake-qt(7)> manual for more information on using CMake with Qt.

AUTOMOC_MACRO_NAMES
Added in version 3.10.

A semicolon-separated list <#cmake-language-lists> of macro names used by AUTOMOC <#prop_tgt:AUTOMOC> to
determine if a C++ file needs to be processed by moc.

This property is only used if the AUTOMOC <#prop_tgt:AUTOMOC> property is ON for this target.

When running AUTOMOC <#prop_tgt: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 <#
variable:CMAKE_AUTOMOC_MACRO_NAMES>.

See also the INTERFACE_AUTOMOC_MACRO_NAMES <#prop_tgt:INTERFACE_AUTOMOC_MACRO_NAMES> target property.

See the cmake-qt(7) <#manual: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 <#prop_tgt:AUTOMOC>

This property is only used if the AUTOMOC <#prop_tgt: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() <#module:FindQt4> macro.

This property is initialized by the value of the CMAKE_AUTOMOC_MOC_OPTIONS <#
variable:CMAKE_AUTOMOC_MOC_OPTIONS> variable if it is set when a target is created, or an empty string
otherwise.

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

EXAMPLE
In this example, the moc tool is invoked with the -D_EXTRA_DEFINE option when generating the moc file for
object.cpp.

CMakeLists.txt

add_executable(mocOptions object.cpp main.cpp)
set_property(TARGET mocOptions PROPERTY AUTOMOC ON)
target_compile_options(mocOptions PRIVATE "-D_EXTRA_DEFINE")
set_property(TARGET mocOptions PROPERTY AUTOMOC_MOC_OPTIONS "-D_EXTRA_DEFINE")
target_link_libraries(mocOptions Qt6::Core)

object.hpp

#ifndef Object_HPP
#define Object_HPP

#include <QObject>

#ifdef _EXTRA_DEFINE
class Object : public QObject
{
Q_OBJECT
public:

Object();

};
#endif

#endif

AUTOMOC_PATH_PREFIX
Added in version 3.16.

When this property is ON, CMake will generate the -p path prefix option for moc on AUTOMOC <#
prop_tgt: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 <#command:target_include_directories>. If so, CMake will compute the relative path
accordingly. If the header is not in the include directories <#command:target_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 <#
variable:CMAKE_AUTOMOC_PATH_PREFIX>, which is OFF by default.

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

Reproducible builds
For reproducible builds it is recommended to keep headers that are moc compiled in one of the target
include directories <#command:target_include_directories> and set AUTOMOC_PATH_PREFIX to ON. 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.

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 commands like QT4_ADD_RESOURCES() <#module:FindQt4>, qt5_add_resources() <https://
doc.qt.io/qt-5/qtcore-cmake-qt5-add-resources.html>, etc. Currently, Qt versions 4 to 6 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:CMAKE_AUTORCC> variable if it is set when a target is created.

By default AUTORCC is processed by a custom command <#command:add_custom_command>. If the .qrc file is
GENERATED <#prop_sf:GENERATED>, a custom target <#command:add_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 <#prop_tgt:AUTORCC_EXECUTABLE>: The rcc executable will be detected automatically, but
can be forced to a certain binary by setting this target property.

AUTORCC_OPTIONS <#prop_tgt:AUTORCC_OPTIONS>: Additional command line options for rcc can be set via this
target property. The corresponding AUTORCC_OPTIONS <#prop_sf:AUTORCC_OPTIONS> source file property can
be used to specify options to be applied only to a specific .qrc file.

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

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

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

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

CMAKE_GLOBAL_AUTORCC_TARGET <#variable: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:cmake-qt(7)> manual for more information on using CMake with Qt.

AUTORCC_EXECUTABLE
Added in version 3.14.

AUTORCC_EXECUTABLE is file path pointing to the rcc executable to use for AUTORCC <#prop_tgt: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:cmake-qt(7)> manual for more information on using CMake with Qt.

AUTORCC_OPTIONS
Additional options for rcc when using AUTORCC <#prop_tgt:AUTORCC>

This property holds additional command line options which will be used when rcc is executed during the
build via AUTORCC <#prop_tgt:AUTORCC>, i.e. it is equivalent to the optional OPTIONS argument of the
qt4_add_resources() <#module:FindQt4> macro.

This property is initialized by the value of the CMAKE_AUTORCC_OPTIONS <#variable:CMAKE_AUTORCC_OPTIONS>
variable if it is set when a target is created, or an empty string otherwise.

The options set on the target may be overridden by AUTORCC_OPTIONS <#prop_sf:AUTORCC_OPTIONS> set on the
.qrc source file.

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

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

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 commands like QT4_WRAP_UI() <#module:FindQt4>, qt5_wrap_ui() <https://doc.qt.io/
qt-5/qtwidgets-cmake-qt5-wrap-ui.html>, etc. Currently, Qt versions 4 to 6 are supported.

This property is initialized by the value of the CMAKE_AUTOUIC <#variable: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 <#prop_tgt: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 <#prop_gbl:GENERATOR_IS_MULTI_CONFIG>
generators.

Where <AUTOGEN_BUILD_DIR> is the value of the target property AUTOGEN_BUILD_DIR <#
prop_tgt:AUTOGEN_BUILD_DIR>.

The include directory is automatically added to the target's INCLUDE_DIRECTORIES <#
prop_tgt:INCLUDE_DIRECTORIES>.

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

AUTOUIC_OPTIONS <#prop_tgt:AUTOUIC_OPTIONS>: Additional command line options for uic can be set via this
target property. The corresponding AUTOUIC_OPTIONS <#prop_sf:AUTOUIC_OPTIONS> source file property can
be used to specify options to be applied only to a specific <base_name>.ui file.

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

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

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

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

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

AUTOGEN_COMMAND_LINE_LENGTH_MAX <#prop_tgt:AUTOGEN_COMMAND_LINE_LENGTH_MAX>: This target property
controls the limit when to use response files for moc or uic processes on Windows.

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

AUTOUIC_EXECUTABLE
Added in version 3.14.

AUTOUIC_EXECUTABLE is file path pointing to the uic executable to use for AUTOUIC <#prop_tgt: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:cmake-qt(7)> manual for more information on using CMake with Qt.

AUTOUIC_OPTIONS
Added in version 3.0.

Additional options for uic when using AUTOUIC <#prop_tgt:AUTOUIC>

This property holds additional command line options which will be used when uic is executed during the
build via AUTOUIC <#prop_tgt:AUTOUIC>, i.e. it is equivalent to the optional OPTIONS argument of the
qt4_wrap_ui() <#module:FindQt4> macro.

This property is initialized by the value of the CMAKE_AUTOUIC_OPTIONS <#variable:CMAKE_AUTOUIC_OPTIONS>
variable if it is set when a target is created, or an empty string otherwise.

The options set on the target may be overridden by AUTOUIC_OPTIONS <#prop_sf:AUTOUIC_OPTIONS> set on the
.ui source file.

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

See the cmake-qt(7) <#manual: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
Added in version 3.9.

Search path list used by AUTOUIC <#prop_tgt:AUTOUIC> to find included .ui files.

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

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

BINARY_DIR
Added in version 3.4.

This read-only property reports the value of the CMAKE_CURRENT_BINARY_DIR <#
variable:CMAKE_CURRENT_BINARY_DIR> variable in the directory in which the target was defined.

BUILD_RPATH
Added in version 3.8.

A semicolon-separated list <#cmake-language-lists> specifying runtime path (RPATH) entries to add to
binaries linked in the build tree (for platforms that support it). By default, CMake sets the runtime
path of binaries in the build tree to contain search paths it knows are needed to find the shared
libraries they link. Projects may set BUILD_RPATH to specify additional search paths.

The build-tree runtime path will not be used for binaries in the install tree. It will be replaced with
the install-tree runtime path during the installation step. See also the INSTALL_RPATH <#
prop_tgt:INSTALL_RPATH> target property.

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

This property supports generator expressions <#manual:cmake-generator-expressions(7)>.

Other settings that affect the build-tree runtime path include:

• The CMAKE_SKIP_RPATH <#variable:CMAKE_SKIP_RPATH> variable completely disables runtime paths in both
the build tree and install tree.

• The SKIP_BUILD_RPATH <#prop_tgt:SKIP_BUILD_RPATH> target property disables setting any runtime path in
the build tree.

• The BUILD_RPATH_USE_ORIGIN <#prop_tgt:BUILD_RPATH_USE_ORIGIN> target property causes the
automatically-generated runtime path to use entries relative to $ORIGIN.

• The BUILD_WITH_INSTALL_RPATH <#prop_tgt:BUILD_WITH_INSTALL_RPATH> target property causes binaries in
the build tree to be built with the install-tree runtime path.

BUILD_RPATH_USE_ORIGIN
Added in version 3.14.

Whether to use relative paths for the build RPATH.

This property is initialized by the value of the variable CMAKE_BUILD_RPATH_USE_ORIGIN <#
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:CMAKE_SKIP_RPATH> variable is set. The runtime path set through the
BUILD_RPATH <#prop_tgt:BUILD_RPATH> target property is also unaffected by this property.

BUILD_WITH_INSTALL_NAME_DIR
Added in version 3.9.

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 <#prop_tgt: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 <#
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 <#policy:CMP0068> is not NEW, the value of
BUILD_WITH_INSTALL_RPATH <#prop_tgt: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 <#prop_tgt:INSTALL_RPATH>. This takes precedence over SKIP_BUILD_RPATH <#
prop_tgt: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:CMAKE_BUILD_WITH_INSTALL_RPATH> variable if it is set when a target is created.

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

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.

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

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

C_EXTENSIONS
Added in version 3.1.

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 <#prop_tgt:C_STANDARD> target
property.

See the cmake-compile-features(7) <#manual: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:CMAKE_C_EXTENSIONS>
variable if set when a target is created and otherwise by the value of CMAKE_C_EXTENSIONS_DEFAULT <#
variable:CMAKE_<LANG>_EXTENSIONS_DEFAULT> (see CMP0128 <#policy:CMP0128>).

C_STANDARD
Added in version 3.1.

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 C standard level, such as Microsoft Visual C++ before VS 16.7, this property has no
effect.

Supported values are:

90 C89/C90

99 C99

11 C11

17 Added in version 3.21.

C17

23 Added in version 3.21.

C23

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 <#prop_tgt:C_STANDARD_REQUIRED> target property.
Additionally, the C_EXTENSIONS <#prop_tgt: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: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:CMAKE_C_STANDARD> variable
if it is set when a target is created.

C_STANDARD_REQUIRED
Added in version 3.1.

Boolean describing whether the value of C_STANDARD <#prop_tgt:C_STANDARD> is a requirement.

If this property is set to ON, then the value of the C_STANDARD <#prop_tgt:C_STANDARD> target property is
treated as a requirement. If this property is OFF or unset, the C_STANDARD <#prop_tgt: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 C standard level, such as Microsoft Visual C++ before VS 16.7,
this property has no effect.

See the cmake-compile-features(7) <#manual: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:CMAKE_C_STANDARD_REQUIRED> variable if it is set when a target is created.

COMMON_LANGUAGE_RUNTIME
Added in version 3.12.

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 the
COMMON_LANGUAGE_RUNTIME target property:

Not Set (default)
Native C++.

"" (set but empty)
Mixed unmanaged/managed C++ using .NET Framework.

netcore
Added in version 3.26.

Mixed unmanaged/managed C++ using .NET Core.

This required VS 2019's v142 toolset or higher.

pure
Managed C++.

safe
Managed C++.

This property is only evaluated Visual Studio Generators <#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 <#prop_tgt: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-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.

COMPATIBLE_INTERFACE_NUMBER_MIN
Properties whose minimum 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.

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.

COMPILE_DEFINITIONS
Preprocessor definitions for compiling a target's sources.

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

Added in version 3.26: Any leading -D on an item will be removed.

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:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> manual for more on defining buildsystem
properties.

The corresponding COMPILE_DEFINITIONS_<CONFIG> <#prop_tgt: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
Added in version 3.1.

Compiler features enabled for this target.

The list of features in this property are a subset of the features listed in the CMAKE_C_COMPILE_FEATURES
<#variable:CMAKE_C_COMPILE_FEATURES>, CMAKE_CUDA_COMPILE_FEATURES <#
variable:CMAKE_CUDA_COMPILE_FEATURES>, and CMAKE_CXX_COMPILE_FEATURES <#
variable:CMAKE_CXX_COMPILE_FEATURES> variables.

Contents of COMPILE_FEATURES may use "generator expressions" with the syntax $<...>. See the
cmake-generator-expressions(7) <#manual:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-compile-features(7) <#manual: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 <#prop_tgt:COMPILE_DEFINITIONS> to pass additional preprocessor definitions.

Note:
This property has been superseded by the COMPILE_OPTIONS <#prop_tgt:COMPILE_OPTIONS> property.
Alternatively, you can also use the target_compile_options() <#command:target_compile_options> command
instead.

COMPILE_OPTIONS
List of options to pass to the compiler.

This property holds a semicolon-separated list <#cmake-language-lists> of options specified so far for
its target. Use the target_compile_options() <#command:target_compile_options> command to append more
options. The options will be added after flags in the CMAKE_<LANG>_FLAGS <#variable:CMAKE_<LANG>_FLAGS>
and CMAKE_<LANG>_FLAGS_<CONFIG> <#variable:CMAKE_<LANG>_FLAGS_<CONFIG>> variables, but before those
propagated from dependencies by the INTERFACE_COMPILE_OPTIONS <#prop_tgt:INTERFACE_COMPILE_OPTIONS>
property.

This property adds compile options for all languages in a target. Use the COMPILE_LANGUAGE <#
genex:COMPILE_LANGUAGE> generator expression to specify per-language compile options.

This property is initialized by the COMPILE_OPTIONS <#prop_dir: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:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> manual for more on defining buildsystem
properties.

Option De-duplication
The final set of options used for a target is constructed by accumulating options from the current target
and the usage requirements of its dependencies. The set of options is de-duplicated to avoid repetition.

Added in version 3.12: While beneficial for individual options, the de-duplication step can break up
option groups. For example, -option A -option B becomes -option A B. One may specify a group of options
using shell-like quoting along with a SHELL: prefix. The SHELL: prefix is dropped, and the rest of the
option string is parsed using the separate_arguments() <#command:separate_arguments> UNIX_COMMAND mode.
For example, "SHELL:-option A" "SHELL:-option B" becomes -option A -option B.

COMPILE_PDB_NAME
Added in version 3.1.

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
<#prop_tgt:PDB_NAME> property to specify the latter.

COMPILE_PDB_NAME_<CONFIG>
Added in version 3.1.

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 <#prop_tgt: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> <#prop_tgt:PDB_NAME_<CONFIG>> property to specify the latter.

COMPILE_PDB_OUTPUT_DIRECTORY
Added in version 3.1.

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: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 <#prop_tgt:PDB_OUTPUT_DIRECTORY> property to specify the latter.

COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG>
Added in version 3.1.

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 <#
prop_tgt: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: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> <#prop_tgt:PDB_OUTPUT_DIRECTORY_<CONFIG>> property to specify the
latter.

COMPILE_WARNING_AS_ERROR
Added in version 3.24.

Specify whether to treat warnings on compile as errors. If enabled, adds a flag to treat warnings on
compile as errors. If the cmake --compile-no-warning-as-error <#
cmdoption-cmake-compile-no-warning-as-error> option is given on the cmake(1) <#manual:cmake(1)> command
line, this property is ignored.

This property is not implemented for all compilers. It is silently ignored if there is no implementation
for the compiler being used. The currently implemented compiler IDs <#variable:CMAKE_<LANG>_COMPILER_ID>
are:

• GNU

• Clang

• AppleClang

• Fujitsu

• FujitsuClang

• IBMClang

• Intel

• IntelLLVM

• LCC

• MSVC

• NVHPC

• NVIDIA (CUDA)

• QCC

• SunPro

• Tasking

• TI

• VisualAge

• XL

• XLClang

This property is initialized by the value of the variable CMAKE_COMPILE_WARNING_AS_ERROR <#
variable:CMAKE_COMPILE_WARNING_AS_ERROR> if it is set when a target is created.

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

This is a configuration-specific version of the OUTPUT_NAME <#prop_tgt: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
CMAKE_<CONFIG>_POSTFIX <#variable:CMAKE_<CONFIG>_POSTFIX> variable if it is set when a target is created.
This property is ignored on macOS for Frameworks and App Bundles.

For macOS see also the FRAMEWORK_MULTI_CONFIG_POSTFIX_<CONFIG> <#
prop_tgt:FRAMEWORK_MULTI_CONFIG_POSTFIX_<CONFIG>> target property.

CROSSCOMPILING_EMULATOR
Added in version 3.3.

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

Added in version 3.15: If this property contains a semicolon-separated list <#cmake-language-lists>, then
the first value is the command and remaining values are its arguments.

Added in version 3.29: Contents of CROSSCOMPILING_EMULATOR may use generator expressions <#
manual:cmake-generator-expressions(7)>.

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

CUDA_ARCHITECTURES
Added in version 3.18.

List of architectures to generate device code for.

An architecture can be suffixed by either -real or -virtual to specify the kind of architecture to
generate code for. If no suffix is given then code is generated for both real and virtual architectures.

A non-empty false value (e.g. OFF) disables adding architectures. This is intended to support packagers
and rare cases where full control over the passed flags is required.

This property is initialized by the value of the CMAKE_CUDA_ARCHITECTURES <#
variable:CMAKE_CUDA_ARCHITECTURES> variable if it is set when a target is created.

The CUDA_ARCHITECTURES target property must be set to a non-empty value on targets that compile CUDA
sources, or it is an error. See policy CMP0104 <#policy:CMP0104>.

The CUDA_ARCHITECTURES may be set to one of the following special values:

all Added in version 3.23.

Compile for all supported major and minor real architectures, and the highest major virtual
architecture.

all-major
Added in version 3.23.

Compile for all supported major real architectures, and the highest major virtual architecture.

native Added in version 3.24.

Compile for the architecture(s) of the host's GPU(s).

Examples
set_target_properties(tgt PROPERTIES CUDA_ARCHITECTURES "35;50;72")

Generates code for real and virtual architectures 30, 50 and 72.

set_property(TARGET tgt PROPERTY CUDA_ARCHITECTURES 70-real 72-virtual)

Generates code for real architecture 70 and virtual architecture 72.

set_property(TARGET tgt PROPERTY CUDA_ARCHITECTURES OFF)

CMake will not pass any architecture flags to the compiler.

CUDA_CUBIN_COMPILATION
Added in version 3.27.

Compile CUDA sources to .cubin files instead of .obj files within Object Libraries <#object-libraries>.

For example:

add_library(mycubin OBJECT a.cu b.cu)
set_property(TARGET mycubin PROPERTY CUDA_CUBIN_COMPILATION ON)

CUDA_EXTENSIONS
Added in version 3.8.

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 <#
prop_tgt:CUDA_STANDARD> target property.

See the cmake-compile-features(7) <#manual: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:CMAKE_CUDA_EXTENSIONS>
variable if set when a target is created and otherwise by the value of CMAKE_CUDA_EXTENSIONS_DEFAULT <#
variable:CMAKE_<LANG>_EXTENSIONS_DEFAULT> (see CMP0128 <#policy:CMP0128>).

CUDA_FATBIN_COMPILATION
Added in version 3.27.

Compile CUDA sources to .fatbin files instead of .obj files within Object Libraries <#object-libraries>.

For example:

add_library(myfbins OBJECT a.cu b.cu)
set_property(TARGET myfbins PROPERTY CUDA_FATBIN_COMPILATION ON)

CUDA_OPTIX_COMPILATION
Added in version 3.27.

Compile CUDA sources to .optixir files instead of .obj files within Object Libraries <#object-libraries>.

For example:

add_library(myoptix OBJECT a.cu b.cu)
set_property(TARGET myoptix PROPERTY CUDA_OPTIX_COMPILATION ON)

CUDA_PTX_COMPILATION
Added in version 3.9.

Compile CUDA sources to .ptx files instead of .obj files within Object Libraries <#object-libraries>.

For example:

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

CUDA_RESOLVE_DEVICE_SYMBOLS
Added in version 3.9.

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 <#
prop_tgt: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.

If this property or CMAKE_CUDA_RESOLVE_DEVICE_SYMBOLS <#variable:CMAKE_CUDA_RESOLVE_DEVICE_SYMBOLS> is
unset, static libraries are treated as if it is disabled while shared, module, and executable targets
behave as if it is on.

If CMAKE_CUDA_RESOLVE_DEVICE_SYMBOLS <#variable:CMAKE_CUDA_RESOLVE_DEVICE_SYMBOLS> has been defined, this
property is initialized to the value the variable and overriding the default behavior.

Note that device linking is not supported for Object Libraries <#object-libraries>.

For instance:

set_property(TARGET mystaticlib PROPERTY CUDA_RESOLVE_DEVICE_SYMBOLS ON)

CUDA_RUNTIME_LIBRARY
Added in version 3.17.

Select the CUDA runtime library for use by compilers targeting the CUDA language.

The allowed case insensitive values are:

None Link with -cudart=none or equivalent flag(s) to use no CUDA runtime library.

Shared Link with -cudart=shared or equivalent flag(s) to use a dynamically-linked CUDA runtime library.

Static Link with -cudart=static or equivalent flag(s) to use a statically-linked CUDA runtime library.

Contents of CUDA_RUNTIME_LIBRARY may use generator expressions <#manual:cmake-generator-expressions(7)>.

If that property is not set then CMake uses an appropriate default value based on the compiler to select
the CUDA runtime library.

Note:
This property has effect only when the CUDA language is enabled. To control the CUDA runtime linking
when only using the CUDA SDK with the C or C++ language we recommend using the FindCUDAToolkit <#
module:FindCUDAToolkit> module.

CUDA_SEPARABLE_COMPILATION
Added in version 3.8.

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:CMAKE_CUDA_SEPARABLE_COMPILATION> variable if it is set when a target is created.

CUDA_STANDARD
Added in version 3.8.

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 CUDA C++98. Note that this maps to the same as 03 internally.

03 CUDA C++03

11 CUDA C++11

14 CUDA C++14. While CMake 3.8 and later recognize 14 as a valid value, CMake 3.9 was the first
version to include support for any compiler.

17 CUDA C++17. While CMake 3.8 and later recognize 17 as a valid value, CMake 3.18 was the first
version to include support for any compiler.

20 Added in version 3.12.

CUDA C++20. While CMake 3.12 and later recognize 20 as a valid value, CMake 3.18 was the first
version to include support for any compiler.

23 Added in version 3.20.

CUDA C++23

26 Added in version 3.25.

CUDA C++26. CMake 3.25 and later recognize 26 as a valid value, no version has support for any
compiler.

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++03 flag if supported. This "decay" behavior may be
controlled with the CUDA_STANDARD_REQUIRED <#prop_tgt:CUDA_STANDARD_REQUIRED> target property.
Additionally, the CUDA_EXTENSIONS <#prop_tgt: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: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:CMAKE_CUDA_STANDARD>
variable if it is set when a target is created.

CUDA_STANDARD_REQUIRED
Added in version 3.8.

Boolean describing whether the value of CUDA_STANDARD <#prop_tgt:CUDA_STANDARD> is a requirement.

If this property is set to ON, then the value of the CUDA_STANDARD <#prop_tgt:CUDA_STANDARD> target
property is treated as a requirement. If this property is OFF or unset, the CUDA_STANDARD <#
prop_tgt: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 1800
(Visual Studio 2013) and lower, this has no effect.

See the cmake-compile-features(7) <#manual: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:CMAKE_CUDA_STANDARD_REQUIRED> variable if it is set when a target is created.

CXX_EXTENSIONS
Added in version 3.1.

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 <#prop_tgt:CXX_STANDARD>
target property.

See the cmake-compile-features(7) <#manual: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:CMAKE_CXX_EXTENSIONS>
variable if set when a target is created and otherwise by the value of CMAKE_CXX_EXTENSIONS_DEFAULT <#
variable:CMAKE_<LANG>_EXTENSIONS_DEFAULT> (see CMP0128 <#policy:CMP0128>).

CXX_MODULE_DIRS
Added in version 3.28.

Semicolon-separated list of base directories of the target's default C++ module set (i.e. the file set
with name and type CXX_MODULES). The property supports generator expressions <#
manual:cmake-generator-expressions(7)>.

This property is normally only set by target_sources(FILE_SET) <#command:target_sources> rather than
being manipulated directly.

See CXX_MODULE_DIRS_<NAME> <#prop_tgt:CXX_MODULE_DIRS_<NAME>> for the list of base directories in other
C++ module sets.

CXX_MODULE_DIRS_<NAME>
Added in version 3.28.

Semicolon-separated list of base directories of the target's <NAME> C++ module set, which has the set
type CXX_MODULES. The property supports generator expressions <#manual:cmake-generator-expressions(7)>.

This property is normally only set by target_sources(FILE_SET) <#command:target_sources> rather than
being manipulated directly.

See CXX_MODULE_DIRS <#prop_tgt:CXX_MODULE_DIRS> for the list of base directories in the default C++
module set. See CXX_MODULE_SETS <#prop_tgt:CXX_MODULE_SETS> for the file set names of all C++ module
sets.

CXX_MODULE_SET
Added in version 3.28.

Semicolon-separated list of files in the target's default C++ module set, (i.e. the file set with name
and type CXX_MODULES). If any of the paths are relative, they are computed relative to the target's
source directory. The property supports generator expressions <#manual:cmake-generator-expressions(7)>.

This property is normally only set by target_sources(FILE_SET) <#command:target_sources> rather than
being manipulated directly.

See CXX_MODULE_SET_<NAME> <#prop_tgt:CXX_MODULE_SET_<NAME>> for the list of files in other C++ module
sets.

CXX_MODULE_SET_<NAME>
Added in version 3.28.

Semicolon-separated list of files in the target's <NAME> C++ module set, which has the set type
CXX_MODULES. If any of the paths are relative, they are computed relative to the target's source
directory. The property supports generator expressions <#manual:cmake-generator-expressions(7)>.

This property is normally only set by target_sources(FILE_SET) <#command:target_sources> rather than
being manipulated directly.

See CXX_MODULE_SET <#prop_tgt:CXX_MODULE_SET> for the list of files in the default C++ module set. See
CXX_MODULE_SETS <#prop_tgt:CXX_MODULE_SETS> for the file set names of all C++ module sets.

CXX_MODULE_SETS
Added in version 3.28.

Read-only list of the target's PRIVATE and PUBLIC C++ module sets (i.e. all file sets with the type
CXX_MODULES). Files listed in these file sets are treated as source files for the purpose of IDE
integration.

C++ module sets may be defined using the target_sources() <#command:target_sources> command FILE_SET
option with type CXX_MODULES.

See also CXX_MODULE_SET_<NAME> <#prop_tgt:CXX_MODULE_SET_<NAME>>, CXX_MODULE_SET <#
prop_tgt:CXX_MODULE_SET> and INTERFACE_CXX_MODULE_SETS <#prop_tgt:INTERFACE_CXX_MODULE_SETS>.

CXX_MODULE_STD
Added in version 3.30.

CXX_MODULE_STD is a boolean specifying whether the target may use import std; its C++ sources or not.

Note:
This setting is meaningful only when experimental support for import std; has been enabled by the
CMAKE_EXPERIMENTAL_CXX_IMPORT_STD gate.

When this property is explicitly set to ON, CMake will add a dependency to a target which provides the
C++ standard library's modules for the C++ standard applied to the target. This target is only applicable
within the current build and will not appear in the exported interfaces of the targets. When consumed,
these targets will be reapplied as necessary.

This property's value is not relevant for targets which disable scanning (see CXX_SCAN_FOR_MODULES <#
prop_tgt:CXX_SCAN_FOR_MODULES>). Additionally, this property only applies to targets utilizing C++23
(cxx_std_23) or newer.

The property supports generator expressions <#manual:cmake-generator-expressions(7)>, however expressions
that depend upon the configuration, the consuming target, or the linker language are not allowed. Whether
a target uses import std should not depend upon such things as it is a static property of the target's
source code.

Targets which are exported with C++ module sources will have this property's resolved value exported.

CXX_SCAN_FOR_MODULES
Added in version 3.28.

CXX_SCAN_FOR_MODULES is a boolean specifying whether CMake will scan C++ sources in the target for module
dependencies. See also the CXX_SCAN_FOR_MODULES <#prop_sf:CXX_SCAN_FOR_MODULES> for per-source settings
which, if set, overrides the target-wide settings.

This property is initialized by the value of the CMAKE_CXX_SCAN_FOR_MODULES <#
variable:CMAKE_CXX_SCAN_FOR_MODULES> variable if it is set when a target is created.

When this property is set ON or unset, CMake will scan the target's CXX sources at build time and add
module dependency information to the compile line as necessary. When this property is set OFF, CMake
will not scan the target's CXX sources at build time.

Note that scanning is only performed if C++20 or higher is enabled for the target. Scanning for modules
in the target's sources belonging to file sets of type CXX_MODULES is always performed.

CXX_STANDARD
Added in version 3.1.

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 C++98

11 C++11

14 C++14

17 Added in version 3.8.

C++17

20 Added in version 3.12.

C++20

23 Added in version 3.20.

C++23

26 Added in version 3.25.

C++26. CMake 3.25 and later recognize 26 as a valid value, no version has support for any
compiler.

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 <#prop_tgt:CXX_STANDARD_REQUIRED> target property.
Additionally, the CXX_EXTENSIONS <#prop_tgt: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: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:CMAKE_CXX_STANDARD>
variable if it is set when a target is created.

CXX_STANDARD_REQUIRED
Added in version 3.1.

Boolean describing whether the value of CXX_STANDARD <#prop_tgt:CXX_STANDARD> is a requirement.

If this property is set to ON, then the value of the CXX_STANDARD <#prop_tgt:CXX_STANDARD> target
property is treated as a requirement. If this property is OFF or unset, the CXX_STANDARD <#
prop_tgt: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 1800
(Visual Studio 2013) and lower, this has no effect.

See the cmake-compile-features(7) <#manual: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:CMAKE_CXX_STANDARD_REQUIRED> variable if it is set when a target is created.

DEBUG_POSTFIX
See target property <CONFIG>_POSTFIX <#prop_tgt:<CONFIG>_POSTFIX>.

This property is a special case of the more-general <CONFIG>_POSTFIX <#prop_tgt:<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 on Windows.

On POSIX platforms, this can optionally be used to control the visibility of symbols.

CMake provides support for such decorations with the GenerateExportHeader <#module:GenerateExportHeader>
module.

DEPLOYMENT_ADDITIONAL_FILES
Added in version 3.13.

Set the WinCE project AdditionalFiles in DeploymentTool in .vcproj files generated by the Visual Studio
Generators <#visual-studio-generators>. 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:

DEPLOYMENT_REMOTE_DIRECTORY
Added in version 3.6.

Set the WinCE project RemoteDirectory in DeploymentTool and RemoteExecutable in DebuggerTool in .vcproj
files generated by the Visual Studio Generators <#visual-studio-generators>. This is useful when you
want to debug on remote WinCE device. For example:

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

produces:

DEPRECATION
Added in version 3.17.

Deprecation message from imported target's developer.

DEPRECATION is the message regarding a deprecation status to be displayed to downstream users of a
target.

The message is formatted as follows:

• Lines that do not start in whitespace are wrapped as paragraph text.

• Lines that start in whitespace are preserved as preformatted text.

DISABLE_PRECOMPILE_HEADERS
Added in version 3.16.

Disables the precompilation of header files specified by PRECOMPILE_HEADERS <#
prop_tgt:PRECOMPILE_HEADERS> property.

If the property is not set, CMake will use the value provided by CMAKE_DISABLE_PRECOMPILE_HEADERS <#
variable:CMAKE_DISABLE_PRECOMPILE_HEADERS>.

DLL_NAME_WITH_SOVERSION
Added in version 3.27.

This property controls whether the SOVERSION <#prop_tgt:SOVERSION> target property is added to the
filename of generated DLL filenames for the Windows platform, which is selected when the WIN32 <#
variable:WIN32> variable is set.

The value of the listed property is appended to the basename of the runtime component of the shared
library target as -<SOVERSION>.

Please note that setting this property has no effect if versioned filenames are globally disabled with
the CMAKE_PLATFORM_NO_VERSIONED_SONAME <#variable:CMAKE_PLATFORM_NO_VERSIONED_SONAME> variable.

DOTNET_SDK
Added in version 3.23.

Specify the .NET SDK for C# projects. For example: Microsoft.NET.Sdk.

This property tells Visual Studio Generators <#visual-studio-generators> for VS 2019 and above to
generate a .NET SDK-style project using the specified SDK. The property is meaningful only to these
generators, and only in C# targets. It is ignored for C++ projects, even if they are managed (e.g. using
COMMON_LANGUAGE_RUNTIME <#prop_tgt:COMMON_LANGUAGE_RUNTIME>).

This property must be a non-empty string to generate .NET SDK-style projects. CMake does not perform any
validations for the value of the property.

This property may be initialized for all targets using the CMAKE_DOTNET_SDK <#variable:CMAKE_DOTNET_SDK>
variable.

Note:
The Visual Studio Generators <#visual-studio-generators> in this version of CMake have not yet learned
to support add_custom_command() <#command:add_custom_command> in .NET SDK-style projects. It is
currently an error to attach a custom command to a target with the DOTNET_SDK property set.

DOTNET_TARGET_FRAMEWORK
Added in version 3.17.

Specify the .NET target framework.

Used to specify the .NET target framework for C++/CLI and C#. For example: netcoreapp2.1.

This property is only evaluated for Visual Studio Generators <#visual-studio-generators> VS 2010 and
above.

Can be initialized for all targets using the variable CMAKE_DOTNET_TARGET_FRAMEWORK <#
variable:CMAKE_DOTNET_TARGET_FRAMEWORK>.

DOTNET_TARGET_FRAMEWORK_VERSION
Added in version 3.12.

Specify the .NET target framework version.

Used to specify the .NET target framework version for C++/CLI and C#. For example: v4.5.

This property is only evaluated for Visual Studio Generators <#visual-studio-generators> VS 2010 and
above.

To initialize this variable for all targets set CMAKE_DOTNET_TARGET_FRAMEWORK <#
variable:CMAKE_DOTNET_TARGET_FRAMEWORK> or CMAKE_DOTNET_TARGET_FRAMEWORK_VERSION <#
variable:CMAKE_DOTNET_TARGET_FRAMEWORK_VERSION>. If both are set, the latter is ignored.

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

A message to display on some generators (such as Makefile Generators <#makefile-generators>) when the
target is built.

ENABLE_EXPORTS
Specify whether an executable or a shared library exports symbols.

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: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 CMAKE_EXECUTABLE_ENABLE_EXPORTS <#
variable:CMAKE_EXECUTABLE_ENABLE_EXPORTS> variable, if it is set when an executable target is created.
If CMAKE_EXECUTABLE_ENABLE_EXPORTS <#variable:CMAKE_EXECUTABLE_ENABLE_EXPORTS> is not set, the
CMAKE_ENABLE_EXPORTS <#variable:CMAKE_ENABLE_EXPORTS> variable is used to initialize the property instead
for backward compatibility reasons. See below for alternative initialization behavior for shared library
targets.

Added in version 3.27: To link with a shared library on macOS, or to a shared framework on any Apple
platform, a linker import file can be used instead of the actual shared library. These linker import
files are also known as text-based stubs, and they have a .tbd file extension.

The generation of these linker import files, as well as their consumption, is controlled by this
property. When this property is set to true on a shared library target, CMake will generate a .tbd file
for the library. Other targets that link to the shared library target will then use this .tbd file when
linking rather than linking to the shared library binary.

Note:
For backward compatibility reasons, this property will be ignored if the
XCODE_ATTRIBUTE_GENERATE_TEXT_BASED_STUBS <#prop_tgt:XCODE_ATTRIBUTE_<an-attribute>> target property
or the CMAKE_XCODE_ATTRIBUTE_GENERATE_TEXT_BASED_STUBS <#
variable:CMAKE_XCODE_ATTRIBUTE_<an-attribute>> variable is set to false.

For shared library targets, this property is initialized by the value of the
CMAKE_SHARED_LIBRARY_ENABLE_EXPORTS <#variable:CMAKE_SHARED_LIBRARY_ENABLE_EXPORTS> variable, if it is
set when the 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 <#prop_dir: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, it may still be listed in an install(TARGETS) <#targets>
command, but the user is responsible for ensuring that the target's build artifacts are not missing or
outdated when an install is performed.

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

Only the "Ninja Multi-Config" generator supports a property value that varies by configuration. For all
other generators the value of this property must be the same for all configurations.

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.

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 <#
prop_tgt:EXCLUDE_FROM_DEFAULT_BUILD>. If the generic EXCLUDE_FROM_DEFAULT_BUILD <#
prop_tgt: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.

EXPORT_BUILD_DATABASE
Added in version 3.31.

Enable/Disable output of a build database for a target.

This property is initialized by the value of the variable CMAKE_EXPORT_BUILD_DATABASE <#
variable:CMAKE_EXPORT_BUILD_DATABASE> if it is set when a target is created.

Note:
This property is meaningful only when experimental support for build databases has been enabled by the
CMAKE_EXPERIMENTAL_EXPORT_BUILD_DATABASE gate.

EXPORT_COMPILE_COMMANDS
Added in version 3.20.

Enable/Disable output of compile commands during generation for a target.

This property is initialized by the value of the variable CMAKE_EXPORT_COMPILE_COMMANDS <#
variable:CMAKE_EXPORT_COMPILE_COMMANDS> if it is set when a target is created.

EXPORT_FIND_PACKAGE_NAME
Note:
Experimental. Gated by CMAKE_EXPERIMENTAL_EXPORT_PACKAGE_DEPENDENCIES.

Control the package name associated with a dependency target when exporting a find_dependency() <#
command:find_dependency> call in install(EXPORT) <#export> or export(EXPORT) <#command:export>. This can
be used to assign a package name to a package that is built by CMake and exported, or to override the
package in the find_package() <#command:find_package> call that created the target.

This property is initialized by CMAKE_EXPORT_FIND_PACKAGE_NAME <#
variable:CMAKE_EXPORT_FIND_PACKAGE_NAME>.

EXPORT_NAME
Exported name for target files.

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

EXPORT_NO_SYSTEM
Added in version 3.25.

This property affects the behavior of the install(EXPORT) <#export> and export() <#command:export>
commands when they install or export the target respectively. When EXPORT_NO_SYSTEM is set to true,
those commands generate an imported target with SYSTEM <#prop_tgt:SYSTEM> property set to false.

See the NO_SYSTEM_FROM_IMPORTED <#prop_tgt:NO_SYSTEM_FROM_IMPORTED> target property to set this behavior
on the target consuming the include directories rather than the one providing them.

EXPORT_PROPERTIES
Added in version 3.12.

List additional properties to export for a target.

This property contains a list of property names that should be exported by the install(EXPORT) <#export>
and export() <#command: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.

Note:
Since CMake 3.19, Interface Libraries <#interface-libraries> may have arbitrary target properties. If
a project exports an interface library with custom properties, the resulting package may not work with
dependents configured by older versions of CMake that reject the custom properties.

FOLDER
For IDEs that present targets using a folder hierarchy, this property specifies the name of the folder to
place the target under. To nest folders, use FOLDER values such as GUI/Dialogs with / characters
separating folder levels. Targets with no FOLDER property will appear as top level entities. Targets
with the same FOLDER property value will appear in the same folder as siblings.

Only some CMake generators honor the FOLDER property (e.g. Xcode <#generator:Xcode> or any of the Visual
Studio <#visual-studio-generators> generators). Those generators that don't will simply ignore it.

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

The global property USE_FOLDERS <#prop_gbl:USE_FOLDERS> must be set to true, otherwise the FOLDER
property is ignored.

Fortran_BUILDING_INSTRINSIC_MODULES
Added in version 3.22.

Instructs the CMake Fortran preprocessor that the target is building Fortran intrinsics for building a
Fortran compiler.

This property is off by default and should be turned only on projects that build a Fortran compiler. It
should not be turned on for projects that use a Fortran compiler.

Turning this property on will correctly add dependencies for building Fortran intrinsic modules whereas
turning the property off will ignore Fortran intrinsic modules in the dependency graph as they are
supplied by the compiler itself.

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 <#
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 <#variable:CMAKE_Fortran_MODULE_DIRECTORY> is set when a
target is created its value is used to initialize this property.

When using one of the Visual Studio Generators <#visual-studio-generators> with the Intel Fortran plugin
installed in Visual Studio, a subdirectory named after the configuration will be appended to the path
where modules are created. For example, if Fortran_MODULE_DIRECTORY is set to C:/some/path, modules will
end up in C:/some/path/Debug (or C:/some/path/Release etc.) when an Intel Fortran .vfproj file is
generated, and in C:/some/path when any other generator is used.

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 <#prop_tgt:INCLUDE_DIRECTORIES> regardless of this property.

Fortran_PREPROCESS
Added in version 3.18.

Control whether the Fortran source file should be unconditionally preprocessed.

If unset or empty, rely on the compiler to determine whether the file should be preprocessed. If
explicitly set to OFF then the file does not need to be preprocessed. If explicitly set to ON, then the
file does need to be preprocessed as part of the compilation step.

When using the Ninja <#generator:Ninja> generator, all source files are first preprocessed in order to
generate module dependency information. Setting this property to OFF will make Ninja skip this step.

Use the source-specific Fortran_PREPROCESS <#prop_sf:Fortran_PREPROCESS> property if a single file needs
to be preprocessed. If the variable CMAKE_Fortran_PREPROCESS <#variable:CMAKE_Fortran_PREPROCESS> is set
when a target is created its value is used to initialize this property.

Note:
For some compilers, NAG, PGI and Solaris Studio, setting this to OFF will have no effect.

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: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 <#
prop_tgt:MACOSX_FRAMEWORK_INFO_PLIST> target property.

For macOS see also the FRAMEWORK_VERSION <#prop_tgt: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_MULTI_CONFIG_POSTFIX_<CONFIG>
Added in version 3.18.

Postfix to append to the framework file name for configuration <CONFIG>, when using a multi-config
generator (like Xcode and Ninja Multi-Config).

When building with configuration <CONFIG> the value of this property is appended to the framework file
name built on disk.

For example, given a framework called my_fw, a value of _debug for the
FRAMEWORK_MULTI_CONFIG_POSTFIX_DEBUG property, and Debug;Release in CMAKE_CONFIGURATION_TYPES <#
variable:CMAKE_CONFIGURATION_TYPES>, the following relevant files would be created for the Debug and
Release configurations:

• Release/my_fw.framework/my_fw

• Release/my_fw.framework/Versions/A/my_fw

• Debug/my_fw.framework/my_fw_debug

• Debug/my_fw.framework/Versions/A/my_fw_debug

For framework targets, this property is initialized by the value of the
CMAKE_FRAMEWORK_MULTI_CONFIG_POSTFIX_<CONFIG> <#variable:CMAKE_FRAMEWORK_MULTI_CONFIG_POSTFIX_<CONFIG>>
variable if it is set when a target is created.

This property is ignored for non-framework targets, and when using single config generators.

FRAMEWORK_VERSION
Added in version 3.4.

Version of a framework created using the FRAMEWORK <#prop_tgt: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() <#command:include_external_msproject>.

GHS_INTEGRITY_APP
Added in version 3.14.

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 <#generator:Green Hills MULTI>.

GHS_NO_SOURCE_GROUP_FILE
Added in version 3.14.

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 <#variable:CMAKE_GHS_NO_SOURCE_GROUP_FILE>
is ON then only a single project file is generated for the target.

Supported on Green Hills MULTI <#generator: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) <#targets> and exported by install(EXPORT) <#
export> and export() <#command: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()
<#command:project> or enable_language() <#command: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 <#prop_tgt:LINKER_LANGUAGE> property to CXX.

HEADER_DIRS
Added in version 3.23.

Semicolon-separated list of base directories of the target's default header set (i.e. the file set with
name and type HEADERS). The property supports generator expressions <#
manual:cmake-generator-expressions(7)>.

This property is normally only set by target_sources(FILE_SET) <#command:target_sources> rather than
being manipulated directly.

See HEADER_DIRS_<NAME> <#prop_tgt:HEADER_DIRS_<NAME>> for the list of base directories in other header
sets.

HEADER_DIRS_<NAME>
Added in version 3.23.

Semicolon-separated list of base directories of the target's <NAME> header set, which has the set type
HEADERS. The property supports generator expressions <#manual:cmake-generator-expressions(7)>.

This property is normally only set by target_sources(FILE_SET) <#command:target_sources> rather than
being manipulated directly.

See HEADER_DIRS <#prop_tgt:HEADER_DIRS> for the list of base directories in the default header set. See
HEADER_SETS <#prop_tgt:HEADER_SETS> for the file set names of all header sets.

HEADER_SET
Added in version 3.23.

Semicolon-separated list of files in the target's default header set, (i.e. the file set with name and
type HEADERS). If any of the paths are relative, they are computed relative to the target's source
directory. The property supports generator expressions <#manual:cmake-generator-expressions(7)>.

This property is normally only set by target_sources(FILE_SET) <#command:target_sources> rather than
being manipulated directly.

See HEADER_SET_<NAME> <#prop_tgt:HEADER_SET_<NAME>> for the list of files in other header sets.

HEADER_SET_<NAME>
Added in version 3.23.

Semicolon-separated list of files in the target's <NAME> header set, which has the set type HEADERS. If
any of the paths are relative, they are computed relative to the target's source directory. The property
supports generator expressions <#manual:cmake-generator-expressions(7)>.

This property is normally only set by target_sources(FILE_SET) <#command:target_sources> rather than
being manipulated directly.

See HEADER_SET <#prop_tgt:HEADER_SET> for the list of files in the default header set. See HEADER_SETS
<#prop_tgt:HEADER_SETS> for the file set names of all header sets.

HEADER_SETS
Added in version 3.23.

Read-only list of the target's PRIVATE and PUBLIC header sets (i.e. all file sets with the type
HEADERS). Files listed in these file sets are treated as source files for the purpose of IDE integration.
The files also have their HEADER_FILE_ONLY <#prop_sf:HEADER_FILE_ONLY> property set to TRUE.

Header sets may be defined using the target_sources() <#command:target_sources> command FILE_SET option
with type HEADERS.

See also HEADER_SET_<NAME> <#prop_tgt:HEADER_SET_<NAME>>, HEADER_SET <#prop_tgt:HEADER_SET> and
INTERFACE_HEADER_SETS <#prop_tgt:INTERFACE_HEADER_SETS>.

HIP_ARCHITECTURES
Added in version 3.21.

List of GPU architectures to for which to generate device code. Architecture names are interpreted based
on CMAKE_HIP_PLATFORM <#variable:CMAKE_HIP_PLATFORM>.

A non-empty false value (e.g. OFF) disables adding architectures. This is intended to support packagers
and rare cases where full control over the passed flags is required.

This property is initialized by the value of the CMAKE_HIP_ARCHITECTURES <#
variable:CMAKE_HIP_ARCHITECTURES> variable if it is set when a target is created.

The HIP compilation model has two modes: whole and separable. Whole compilation generates device code at
compile time. Separable compilation generates device code at link time. Therefore the HIP_ARCHITECTURES
target property should be set on targets that compile or link with any HIP sources.

Examples
set_property(TARGET tgt PROPERTY HIP_ARCHITECTURES gfx801 gfx900)

Generates code for both gfx801 and gfx900.

HIP_EXTENSIONS
Added in version 3.21.

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 HIP/C++ standard level is controlled by the HIP_STANDARD <#
prop_tgt:HIP_STANDARD> target property.

See the cmake-compile-features(7) <#manual: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_HIP_EXTENSIONS <#variable:CMAKE_HIP_EXTENSIONS>
variable if set when a target is created and otherwise by the value of CMAKE_HIP_EXTENSIONS_DEFAULT <#
variable:CMAKE_<LANG>_EXTENSIONS_DEFAULT> (see CMP0128 <#policy:CMP0128>).

HIP_STANDARD
Added in version 3.21.

The HIP/C++ standard requested to build this target.

Supported values are:

98 HIP C++98

11 HIP C++11

14 HIP C++14

17 HIP C++17

20 HIP C++20

23 HIP C++23

26 Added in version 3.25.

HIP C++26. CMake 3.25 and later recognize 26 as a valid value, no version has support for any
compiler.

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 HIP_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 HIP_STANDARD_REQUIRED <#prop_tgt:HIP_STANDARD_REQUIRED> target property.
Additionally, the HIP_EXTENSIONS <#prop_tgt:HIP_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: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_HIP_STANDARD <#variable:CMAKE_HIP_STANDARD>
variable if it is set when a target is created.

HIP_STANDARD_REQUIRED
Added in version 3.21.

Boolean describing whether the value of HIP_STANDARD <#prop_tgt:HIP_STANDARD> is a requirement.

If this property is set to ON, then the value of the HIP_STANDARD <#prop_tgt:HIP_STANDARD> target
property is treated as a requirement. If this property is OFF or unset, the HIP_STANDARD <#
prop_tgt:HIP_STANDARD> target property is treated as optional and may "decay" to a previous standard if
the requested is not available.

See the cmake-compile-features(7) <#manual: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_HIP_STANDARD_REQUIRED <#
variable:CMAKE_HIP_STANDARD_REQUIRED> variable if it is set when a target is created.

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)

#include <mydir/myheader.h>

allowing the dependency to be followed.

This property applies to sources in the target on which it is set.

IMPORTED
Read-only indication of whether a target is IMPORTED.

The boolean value of this property is True for targets created with the IMPORTED option to
add_executable() <#command:add_executable> or add_library() <#command:add_library>. It is False for
targets built within the project.

IMPORTED_COMMON_LANGUAGE_RUNTIME
Added in version 3.12.

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

Ignored for non-imported targets.

See also the COMMON_LANGUAGE_RUNTIME <#prop_tgt:COMMON_LANGUAGE_RUNTIME> target property.

IMPORTED_CONFIGURATIONS
Configurations provided for an imported target <#imported-targets>.

Set this to the list of configuration names available for an imported target. For each configuration
named, the imported target's artifacts must be specified in other target properties:

• IMPORTED_LOCATION_<CONFIG> <#prop_tgt:IMPORTED_LOCATION_<CONFIG>>, or

• IMPORTED_IMPLIB_<CONFIG> <#prop_tgt:IMPORTED_IMPLIB_<CONFIG>> (on DLL platforms, on AIX for Executables
<#binary-executables> or on Apple for Shared Libraries <#normal-libraries>), or

• IMPORTED_OBJECTS_<CONFIG> <#prop_tgt:IMPORTED_OBJECTS_<CONFIG>> (for Object Libraries <#
object-libraries>), or

• IMPORTED_LIBNAME_<CONFIG> <#prop_tgt:IMPORTED_LIBNAME_<CONFIG>> (for Interface Libraries <#
interface-libraries>).

The configuration names correspond to those defined in the project from which the target is imported. If
the importing project uses a different set of configurations, the names may be mapped using the
MAP_IMPORTED_CONFIG_<CONFIG> <#prop_tgt:MAP_IMPORTED_CONFIG_<CONFIG>> target property.

The IMPORTED_CONFIGURATIONS property is ignored for non-imported targets.

IMPORTED_CXX_MODULES_COMPILE_DEFINITIONS
Added in version 3.28.

Preprocessor definitions for compiling an IMPORTED target's C++ module sources.

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

IMPORTED_CXX_MODULES_COMPILE_FEATURES
Added in version 3.28.

Compiler features enabled for this IMPORTED target's C++ modules.

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

IMPORTED_CXX_MODULES_COMPILE_OPTIONS
Added in version 3.28.

List of options to pass to the compiler for this IMPORTED target's C++ modules.

IMPORTED_CXX_MODULES_INCLUDE_DIRECTORIES
Added in version 3.28.

List of preprocessor include file search directories when compiling C++ modules for IMPORTED targets.

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

IMPORTED_CXX_MODULES_LINK_LIBRARIES
Added in version 3.28.

List of direct dependencies to use for usage requirements for C++ modules in the target's C++ modules.

IMPORTED_GLOBAL
Added in version 3.11.

Indication of whether an IMPORTED target <#imported-targets> is globally visible.

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

For targets created with the IMPORTED option to add_executable() <#command:add_executable> or
add_library() <#command: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.

Note:
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.

Note:
Local ALIAS targets <#alias-targets> created before promoting an IMPORTED target <#imported-targets>
from LOCAL to GLOBAL, keep their initial scope (see ALIAS_GLOBAL <#prop_tgt:ALIAS_GLOBAL> target
property).

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

This property may be set:

• On DLL platforms, to the location of the .lib part of the DLL.

• Added in version 3.16: On AIX, to an import file (e.g. .imp) created for executables that export
symbols (see the ENABLE_EXPORTS <#prop_tgt:ENABLE_EXPORTS> target property).

• Added in version 3.27: On Apple platforms, to an import file (e.g. .tbd) created for shared libraries
or frameworks (see the ENABLE_EXPORTS <#prop_tgt:ENABLE_EXPORTS> target property). For frameworks,
this is the location of the .tbd file symlink just inside the framework folder.

• Added in version 3.28: On non-DLL platforms, to the location of a shared library. When set without
also specifying an IMPORTED_LOCATION <#prop_tgt:IMPORTED_LOCATION>, the library is considered to be a
stub, and its location will not be added as a runtime search path to dependents that link it.

Changed in version 3.28: If an imported target is an Apple framework or XCFramework, the preferred
arrangement is to set IMPORTED_LOCATION <#prop_tgt:IMPORTED_LOCATION> to the .framework or .xcframework
directory. CMake will then find the relevant .tbd file inside that framework or XCFramework
automatically without requiring IMPORTED_IMPLIB to be set.

The IMPORTED_IMPLIB target property may be overridden for a given configuration <CONFIG> by the
configuration-specific IMPORTED_IMPLIB_<CONFIG> <#prop_tgt:IMPORTED_IMPLIB_<CONFIG>> target property.
Furthermore, the MAP_IMPORTED_CONFIG_<CONFIG> <#prop_tgt: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 <#
prop_tgt:IMPORTED_CONFIGURATIONS> target property may be selected and its IMPORTED_IMPLIB_<CONFIG> <#
prop_tgt:IMPORTED_IMPLIB_<CONFIG>> value used.

This property is ignored for non-imported targets.

IMPORTED_IMPLIB_<CONFIG>
<CONFIG>-specific version of IMPORTED_IMPLIB <#prop_tgt:IMPORTED_IMPLIB> property.

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

IMPORTED_LIBNAME
Added in version 3.8.

Specify the link library name for an imported <#imported-targets> Interface Library <#
interface-libraries>.

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 <#imported-targets> Interface Libraries <#
interface-libraries> and is rejected on targets of other types (for which the IMPORTED_LOCATION <#
prop_tgt:IMPORTED_LOCATION> target property may be used).

IMPORTED_LIBNAME_<CONFIG>
Added in version 3.8.

<CONFIG>-specific version of IMPORTED_LIBNAME <#prop_tgt:IMPORTED_LIBNAME> property.

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

IMPORTED_LINK_DEPENDENT_LIBRARIES
Dependent shared libraries of an imported shared library.

Shared libraries may be linked to other shared libraries as part of their implementation. On some
platforms the linker searches for the dependent libraries of shared libraries they are 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 <#
prop_tgt: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_DEPENDENT_LIBRARIES_<CONFIG>
<CONFIG>-specific version of IMPORTED_LINK_DEPENDENT_LIBRARIES <#
prop_tgt: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_INTERFACE_LANGUAGES
Languages compiled into an IMPORTED static library.

Set this to the list of languages of source files compiled to produce a STATIC IMPORTED library (such as
C or CXX). CMake accounts for these languages when computing how to link a target to the imported
library. For example, when a C executable links to an imported C++ static library CMake chooses the C++
linker to satisfy language runtime dependencies of the static library.

This property is ignored for targets that are not STATIC libraries. This property is ignored for
non-imported targets.

IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
<CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LANGUAGES <#
prop_tgt: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_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 <#prop_tgt: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 <#
prop_tgt:INTERFACE_LINK_LIBRARIES> property.

This property is deprecated. Use INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES> instead.

IMPORTED_LINK_INTERFACE_LIBRARIES_<CONFIG>
<CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LIBRARIES <#
prop_tgt: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 <#
prop_tgt:INTERFACE_LINK_LIBRARIES> property.

This property is deprecated. Use INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES> instead.

IMPORTED_LINK_INTERFACE_MULTIPLICITY
Repetition count for cycles of IMPORTED static libraries.

This is LINK_INTERFACE_MULTIPLICITY <#prop_tgt:LINK_INTERFACE_MULTIPLICITY> for IMPORTED targets.

IMPORTED_LINK_INTERFACE_MULTIPLICITY_<CONFIG>
<CONFIG>-specific version of IMPORTED_LINK_INTERFACE_MULTIPLICITY <#
prop_tgt:IMPORTED_LINK_INTERFACE_MULTIPLICITY>.

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

IMPORTED_LOCATION
Full path to the main file on disk for an IMPORTED target.

Set this to the location of an IMPORTED target file on disk. For executables this is the location of the
executable file. For 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 application
bundles on macOS this is the location of the executable file inside Contents/MacOS within the bundle
folder. 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.

Added in version 3.28: For ordinary frameworks on Apple platforms, this may be the location of the
.framework folder itself. For XCFrameworks, it may be the location of the .xcframework folder, in which
case any target that links against it will get the selected library's Headers directory as a usage
requirement.

The IMPORTED_LOCATION target property may be overridden for a given configuration <CONFIG> by the
configuration-specific IMPORTED_LOCATION_<CONFIG> <#prop_tgt:IMPORTED_LOCATION_<CONFIG>> target property.
Furthermore, the MAP_IMPORTED_CONFIG_<CONFIG> <#prop_tgt: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 <#
prop_tgt:IMPORTED_CONFIGURATIONS> target property may be selected and its IMPORTED_LOCATION_<CONFIG> <#
prop_tgt:IMPORTED_LOCATION_<CONFIG>> value used.

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

For platforms with import libraries (e.g. Windows, AIX or Apple) see also IMPORTED_IMPLIB <#
prop_tgt:IMPORTED_IMPLIB>.

IMPORTED_LOCATION_<CONFIG>
<CONFIG>-specific version of IMPORTED_LOCATION <#prop_tgt:IMPORTED_LOCATION> property.

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

IMPORTED_NO_SONAME
Specifies that an IMPORTED shared library target has no 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_NO_SONAME_<CONFIG>
<CONFIG>-specific version of IMPORTED_NO_SONAME <#prop_tgt:IMPORTED_NO_SONAME> property.

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

IMPORTED_OBJECTS
Added in version 3.9.

A semicolon-separated list <#cmake-language-lists> of absolute paths to the object files on disk for an
imported <#imported-targets> object library <#object-libraries>.

Ignored for non-imported targets.

Projects may skip IMPORTED_OBJECTS if the configuration-specific property IMPORTED_OBJECTS_<CONFIG> <#
prop_tgt:IMPORTED_OBJECTS_<CONFIG>> is set instead, except in situations as noted in the section below.

Xcode Generator Considerations
Added in version 3.20.

For Apple platforms, a project may be built for more than one architecture. This is controlled by the
CMAKE_OSX_ARCHITECTURES <#variable:CMAKE_OSX_ARCHITECTURES> variable. For all but the Xcode <#
generator:Xcode> generator, CMake invokes compilers once per source file and passes multiple -arch flags,
leading to a single object file which will be a universal binary. Such object files work well when
listed in the IMPORTED_OBJECTS of a separate CMake build, even for the Xcode <#generator:Xcode>
generator. But producing such object files with the Xcode <#generator:Xcode> generator is more
difficult, since it invokes the compiler once per architecture for each source file. Unlike the other
generators, it does not generate universal object file binaries.

A further complication with the Xcode <#generator:Xcode> generator is that when targeting device
platforms (iOS, tvOS, visionOS or watchOS), the Xcode <#generator:Xcode> generator has the ability to use
either the device or simulator SDK without needing CMake to be re-run. The SDK can be selected at build
time. But since some architectures can be supported by both the device and the simulator SDKs (e.g.
arm64 with Xcode 12 or later), not all combinations can be represented in a single universal binary. The
only solution in this case is to have multiple object files.

IMPORTED_OBJECTS doesn't support generator expressions, so every file it lists needs to be valid for
every architecture and SDK. If incorporating object files that are not universal binaries, the path
and/or file name of each object file has to somehow encapsulate the different architectures and SDKs.
With the Xcode <#generator:Xcode> generator, Xcode variables of the form $(...) can be used to represent
these aspects and Xcode will substitute the appropriate values at build time. CMake doesn't interpret
these variables and embeds them unchanged in the Xcode project file. $(CURRENT_ARCH) can be used to
represent the architecture, while $(EFFECTIVE_PLATFORM_NAME) can be used to differentiate between SDKs.

The following shows one example of how these two variables can be used to refer to an object file whose
location depends on both the SDK and the architecture:

add_library(someObjs OBJECT IMPORTED)

set_property(TARGET someObjs PROPERTY IMPORTED_OBJECTS
# Quotes are required because of the ()
"/path/to/somewhere/objects$(EFFECTIVE_PLATFORM_NAME)/$(CURRENT_ARCH)/func.o"
)

# Example paths:
# /path/to/somewhere/objects-iphoneos/arm64/func.o
# /path/to/somewhere/objects-iphonesimulator/x86_64/func.o

In some cases, you may want to have configuration-specific object files as well. The $(CONFIGURATION)
Xcode variable is often used for this and can be used in conjunction with the others mentioned above:

add_library(someObjs OBJECT IMPORTED)
set_property(TARGET someObjs PROPERTY IMPORTED_OBJECTS
"/path/to/somewhere/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)/$(CURRENT_ARCH)/func.o"
)

# Example paths:
# /path/to/somewhere/Release-iphoneos/arm64/func.o
# /path/to/somewhere/Debug-iphonesimulator/x86_64/func.o

When any Xcode variable is used, CMake is not able to fully evaluate the path(s) at configure time. One
consequence of this is that the configuration-specific IMPORTED_OBJECTS_<CONFIG> <#
prop_tgt:IMPORTED_OBJECTS_<CONFIG>> properties cannot be used, since CMake cannot determine whether an
object file exists at a particular <CONFIG> location. The IMPORTED_OBJECTS property must be used for
these situations and the configuration-specific aspects of the path should be handled by the
$(CONFIGURATION) Xcode variable.

IMPORTED_OBJECTS_<CONFIG>
Added in version 3.9.

<CONFIG>-specific version of IMPORTED_OBJECTS <#prop_tgt:IMPORTED_OBJECTS> property.

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

Xcode Generator Considerations
Do not use this <CONFIG>-specific property if you need to use Xcode variables like $(CURRENT_ARCH) or
$(EFFECTIVE_PLATFORM_NAME) in the value. The <CONFIG>-specific properties will be ignored in such cases
because CMake cannot determine whether a file exists at the configuration-specific path at configuration
time. For such cases, use IMPORTED_OBJECTS <#prop_tgt:IMPORTED_OBJECTS> instead.

IMPORTED_SONAME
The soname of an IMPORTED target of shared library type.

Set this to the soname embedded in an imported shared library. This is meaningful only on platforms
supporting the feature. Ignored for non-imported targets.

IMPORTED_SONAME_<CONFIG>
<CONFIG>-specific version of IMPORTED_SONAME <#prop_tgt:IMPORTED_SONAME> property.

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

IMPORT_PREFIX
What comes before the import library name.

Similar to the target property PREFIX <#prop_tgt: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 <#prop_tgt: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: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:set_property> command. A target
gets its initial value for this property from the value of the INCLUDE_DIRECTORIES <#
prop_dir:INCLUDE_DIRECTORIES> directory property. Both directory and target property values are adjusted
by calls to the include_directories() <#command: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) <#
manual:cmake-generator-expressions(7)> with the syntax $<...>. See the cmake-generator-expressions(7) <#
manual:cmake-generator-expressions(7)> manual for available expressions. See the cmake-buildsystem(7) <#
manual:cmake-buildsystem(7)> manual for more on defining buildsystem properties.

INSTALL_NAME_DIR
Directory name for installed targets on Apple platforms.

INSTALL_NAME_DIR is a string specifying the directory portion of the "install_name" field of shared
libraries on Apple platforms for installed targets. When not set, the default directory used is
determined by MACOSX_RPATH <#prop_tgt:MACOSX_RPATH>. If the BUILD_WITH_INSTALL_NAME_DIR <#
prop_tgt:BUILD_WITH_INSTALL_NAME_DIR> property is set, this will be used already in the build tree.
Policies CMP0068 <#policy:CMP0068> and CMP0042 <#policy:CMP0042> are also relevant.

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

This property supports generator expressions <#manual:cmake-generator-expressions(7)>. In particular,
the $<INSTALL_PREFIX> <#genex:INSTALL_PREFIX> generator expression can be used to set the directory
relative to the install-time prefix.

On platforms that support runtime paths (RPATH), refer to the INSTALL_RPATH <#prop_tgt:INSTALL_RPATH>
target property. Under Windows, the TARGET_RUNTIME_DLLS <#genex:TARGET_RUNTIME_DLLS> generator
expression is related.

INSTALL_REMOVE_ENVIRONMENT_RPATH
Added in version 3.16.

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 <#prop_tgt: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 <#
variable:CMAKE_INSTALL_REMOVE_ENVIRONMENT_RPATH> when the target is created.

INSTALL_RPATH
The rpath to use for installed targets.

By default, the install rpath is empty. It can be set using this property, which is 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 <#variable:CMAKE_INSTALL_RPATH> if it is set
when a target is created. Beside setting the install rpath manually, using the
INSTALL_RPATH_USE_LINK_PATH <#prop_tgt:INSTALL_RPATH_USE_LINK_PATH> target property it can also be
generated automatically by CMake.

Normally CMake uses the build tree for the RPATH when building executables etc on systems that use RPATH,
see the BUILD_RPATH <#prop_tgt:BUILD_RPATH> target property. When the software is installed the targets
are edited (or relinked) by CMake (see CMAKE_NO_BUILTIN_CHRPATH <#variable:CMAKE_NO_BUILTIN_CHRPATH>) to
have the install RPATH. This editing during installation can be avoided via the BUILD_WITH_INSTALL_RPATH
<#prop_tgt:BUILD_WITH_INSTALL_RPATH> target property.

For handling toolchain-dependent RPATH entries the INSTALL_REMOVE_ENVIRONMENT_RPATH <#
prop_tgt:INSTALL_REMOVE_ENVIRONMENT_RPATH> can be used. Runtime paths can be disabled completely via the
CMAKE_SKIP_RPATH <#variable:CMAKE_SKIP_RPATH> variable.

Because the rpath may contain ${ORIGIN}, which coincides with CMake syntax, the contents of INSTALL_RPATH
are properly escaped in the cmake_install.cmake script (see policy CMP0095 <#policy:CMP0095>.)

This property supports generator expressions <#manual:cmake-generator-expressions(7)>.

On Apple platforms, refer to the INSTALL_NAME_DIR <#prop_tgt:INSTALL_NAME_DIR> target property. Under
Windows, the TARGET_RUNTIME_DLLS <#genex:TARGET_RUNTIME_DLLS> generator expression is related.

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 to the runtime search path
(rpath) of installed binaries any directories outside the project that are in the linker search path or
contain linked library files. The directories are appended after the value of the INSTALL_RPATH <#
prop_tgt:INSTALL_RPATH> target property.

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

INTERFACE_AUTOMOC_MACRO_NAMES
Added in version 3.27.

A semicolon-separated list <#cmake-language-lists> of macro names for AUTOMOC <#prop_tgt:AUTOMOC> to be
propagated to consumers.

When a target with AUTOMOC <#prop_tgt:AUTOMOC> enabled links to a library that sets
INTERFACE_AUTOMOC_MACRO_NAMES, the target inherits the listed macro names and merges them with those
specified in its own AUTOMOC_MACRO_NAMES <#prop_tgt:AUTOMOC_MACRO_NAMES> property. The target will then
automatically generate MOC files for source files that contain the inherited macro names too, not just
the macro names specified in its own AUTOMOC_MACRO_NAMES <#prop_tgt:AUTOMOC_MACRO_NAMES> property.

By default INTERFACE_AUTOMOC_MACRO_NAMES is empty.

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

Example 1
In this example, myapp inherits the macro names STATIC_LIB_1 and STATIC_LIB_2 from static_lib. The moc
tool will then automatically be run on any of the myapp sources which contain STATIC_LIB_1 or
STATIC_LIB_2.

set(AUTOMOC ON)
add_executable(myapp main.cpp)
target_link_libraries(myapp PRIVATE static_lib)

add_library(static_lib STATIC static.cpp)
set_property(TARGET static_lib PROPERTY
INTERFACE_AUTOMOC_MACRO_NAMES "STATIC_LIB_1;STATIC_LIB_2"
)

Example 2
In this example, the INTERFACE_AUTOMOC_MACRO_NAMES target property of the various *_deep_lib libraries
will propagate to shared_lib, static_lib and interface_lib. Because the linking relationships are
specified as PUBLIC and INTERFACE, those macro names will also further propagate transitively up to app.

set(AUTOMOC ON)

add_library(shared_deep_lib SHARED deep_lib.cpp)
add_library(static_deep_lib STATIC deep_lib.cpp)
add_library(interface_deep_lib INTERFACE)

set_property(TARGET shared_deep_lib PROPERTY
INTERFACE_AUTOMOC_MACRO_NAMES "SHARED_LINK_LIB"
)
set_property(TARGET static_deep_lib PROPERTY
INTERFACE_AUTOMOC_MACRO_NAMES "STATIC_LINK_LIB"
)
set_property(TARGET interface_deep_lib PROPERTY
INTERFACE_AUTOMOC_MACRO_NAMES "INTERFACE_LINK_LIB"
)

add_library(shared_lib SHARED lib.cpp)
add_library(static_lib STATIC lib.cpp)
add_library(interface_lib INTERFACE)

# PUBLIC and INTERFACE here ensure the macro names propagate to any
# consumers of shared_lib, static_lib or interface_lib too
target_link_libraries(shared_lib PUBLIC shared_deep_lib)
target_link_libraries(static_lib PUBLIC static_deep_lib)
target_link_libraries(interface_lib INTERFACE interface_deep_lib)

# This consumer will receive all three of the above custom macro names as
# transitive usage requirements
add_executable(app main.cpp)
target_link_libraries(app PRIVATE shared_lib static_lib interface_lib)

In the above:

• shared_lib sources will be processed by moc if they contain SHARED_LINK_LIB.

• static_lib sources will be processed by moc if they contain STATIC_LINK_LIB.

• app sources will be processed by moc if they contain SHARED_LINK_LIB, STATIC_LINK_LIB or
INTERFACE_LINK_LIB.

INTERFACE_AUTOUIC_OPTIONS
Added in version 3.0.

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 <#prop_tgt: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:target_link_libraries> command.

This property supports generator expressions. See the cmake-generator-expressions(7) <#
manual: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: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() <#command: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:cmake-generator-expressions(7)> manual for available
expressions. See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> -manual for more on defining
buildsystem properties.

INTERFACE_COMPILE_FEATURES
Added in version 3.1.

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: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.

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

See the cmake-compile-features(7) <#manual: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: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.

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

INTERFACE_CXX_MODULE_SETS
Added in version 3.28.

Read-only list of the target's PUBLIC C++ module sets (i.e. all file sets with the type CXX_MODULES).
Files listed in these C++ module sets can be installed with install(TARGETS) <#targets> and exported with
install(EXPORT) <#export> and export() <#command:export>.

C++ module sets may be defined using the target_sources() <#command:target_sources> command FILE_SET
option with type CXX_MODULES.

See also CXX_MODULE_SETS <#prop_tgt:CXX_MODULE_SETS>.

INTERFACE_HEADER_SETS
Added in version 3.23.

Read-only list of the target's INTERFACE and PUBLIC header sets (i.e. all file sets with the type
HEADERS). Files listed in these header sets can be installed with install(TARGETS) <#targets> and
exported with install(EXPORT) <#export> and export() <#command:export>.

Header sets may be defined using the target_sources() <#command:target_sources> command FILE_SET option
with type HEADERS.

See also HEADER_SETS <#prop_tgt:HEADER_SETS>.

INTERFACE_HEADER_SETS_TO_VERIFY
Added in version 3.24.

Used to specify which PUBLIC and INTERFACE header sets of a target should be verified.

This property contains a semicolon-separated list of header sets which should be verified if
VERIFY_INTERFACE_HEADER_SETS <#prop_tgt:VERIFY_INTERFACE_HEADER_SETS> is set to TRUE. If the list is
empty, all PUBLIC and INTERFACE header sets are verified. (If the project does not want to verify any
header sets on the target, simply set VERIFY_INTERFACE_HEADER_SETS <#
prop_tgt:VERIFY_INTERFACE_HEADER_SETS> to FALSE.)

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: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.

Contents of INTERFACE_INCLUDE_DIRECTORIES may use "generator expressions" with the syntax $<...>. See
the cmake-generator-expressions(7) <#manual:cmake-generator-expressions(7)> manual for available
expressions. See the cmake-buildsystem(7) <#manual: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 <#genex: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 <#genex: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 <#
prop_tgt: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 <#creating-relocatable-packages> section of the cmake-packages(7)
<#manual: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
Added in version 3.13.

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

This property is supported only by Ninja <#generator:Ninja> and Makefile Generators <#
makefile-generators>. It is intended to specify dependencies on "linker scripts" for custom Makefile
link rules.

Contents of INTERFACE_LINK_DEPENDS may use "generator expressions" with the syntax $<...>. See the
cmake-generator-expressions(7) <#manual:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual: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
Added in version 3.13.

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: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.

Contents of INTERFACE_LINK_DIRECTORIES may use "generator expressions" with the syntax $<...>. See the
cmake-generator-expressions(7) <#manual:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual: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: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 <#prop_tgt:LINK_INTERFACE_LIBRARIES> or
LINK_INTERFACE_LIBRARIES_<CONFIG> <#prop_tgt:LINK_INTERFACE_LIBRARIES_<CONFIG>> property if policy
CMP0022 <#policy:CMP0022> is OLD or unset.

The value of this property is used by the generators when constructing the link rule for a dependent
target. A dependent target's direct link dependencies, specified by its LINK_LIBRARIES <#
prop_tgt:LINK_LIBRARIES> target property, are linked first, followed by indirect dependencies from the
transitive closure of the direct dependencies' INTERFACE_LINK_LIBRARIES properties. See policy CMP0022
<#policy:CMP0022>.

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

Note:
A call to target_link_libraries(<target> ...) <#command:target_link_libraries> may update this
property on <target>. If <target> was not created in the same directory as the call then
target_link_libraries() <#command:target_link_libraries> will wrap each entry with the form
::@(directory-id);...;::@, where the ::@ is literal 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) <#export> and export() <#command:export> commands.

INTERFACE_LINK_LIBRARIES adds transitive link dependencies for a target's dependents. In advanced use
cases, one may update the direct link dependencies of a target's dependents by using the
INTERFACE_LINK_LIBRARIES_DIRECT <#prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT> and
INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE <#prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE> target
properties.

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.

INTERFACE_LINK_LIBRARIES_DIRECT
Added in version 3.24.

List of libraries that consumers of this library should treat as direct link dependencies.

This target property may be set to include items in a dependent target's final set of direct link
dependencies. See the INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE <#
prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE> target property to exclude items.

The initial set of a dependent target's direct link dependencies is specified by its LINK_LIBRARIES <#
prop_tgt:LINK_LIBRARIES> target property. Indirect link dependencies are specified by the transitive
closure of the direct link dependencies' INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES>
properties. Any link dependency may specify additional direct link dependencies using the
INTERFACE_LINK_LIBRARIES_DIRECT target property. The set of direct link dependencies is then filtered to
exclude items named by any dependency's INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE <#
prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE> target property.

The value of INTERFACE_LINK_LIBRARIES_DIRECT may use generator expressions <#
manual:cmake-generator-expressions(7)>.

Note:
The INTERFACE_LINK_LIBRARIES_DIRECT target property is intended for advanced use cases such as
injection of static plugins into a consuming executable. It should not be used as a substitute for
organizing normal calls to target_link_libraries() <#command:target_link_libraries>.

Direct Link Dependencies as Usage Requirements
The INTERFACE_LINK_LIBRARIES_DIRECT and INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE target properties are
usage requirements <#target-usage-requirements>. Their effects propagate to dependent targets
transitively, and can therefore affect the direct link dependencies of every target in a chain of
dependent libraries. Whenever some library target X links to another library target Y whose direct or
transitive usage requirements contain INTERFACE_LINK_LIBRARIES_DIRECT or
INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE, the properties may affect X's list of direct link dependencies:

• If X is a shared library or executable, its dependencies are linked. They also affect the usage
requirements with which X's sources are compiled.

• If X is a static library or object library, it does not actually link, so its dependencies at most
affect the usage requirements with which X's sources are compiled.

The properties may also affect the list of direct link dependencies on X's dependents:

• If X links Y publicly:

target_link_libraries(X PUBLIC Y)

then Y is placed in X's INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES>, so Y's usage
requirements, including INTERFACE_LINK_LIBRARIES_DIRECT, INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE, and
the usage requirements declared by the direct link dependencies they add, are propagated to X's
dependents.

• If X is a static library or object library, and links Y privately:

target_link_libraries(X PRIVATE Y)

then $<LINK_ONLY:Y> is placed in X's INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES>.
Y's linking requirements, including INTERFACE_LINK_LIBRARIES_DIRECT,
INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE, and the transitive link dependencies declared by the direct
link dependencies they add, are propagated to X's dependents. However, Y's non-linking usage
requirements are blocked by the LINK_ONLY <#genex:LINK_ONLY> generator expression, and are not
propagated to X's dependents.

• If X is a shared library or executable, and links Y privately:

target_link_libraries(X PRIVATE Y)

then Y is not placed in X's INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES>, so Y's usage
requirements, even INTERFACE_LINK_LIBRARIES_DIRECT and INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE, are not
propagated to X's dependents.

• In all cases, the content of X's INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES> is not
affected by Y's INTERFACE_LINK_LIBRARIES_DIRECT or INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE.

One may limit the effects of INTERFACE_LINK_LIBRARIES_DIRECT and INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE
to a subset of dependent targets by using the TARGET_PROPERTY <#genex:TARGET_PROPERTY> generator
expression. For example, to limit the effects to executable targets, use an entry of the form:

"$<$<STREQUAL:$<TARGET_PROPERTY:TYPE>,EXECUTABLE>:...>"

Similarly, to limit the effects to specific targets, use an entry of the form:

"$<$<BOOL:$<TARGET_PROPERTY:USE_IT>>:...>"

This entry will only affect targets that set their USE_IT target property to a true value.

Direct Link Dependency Ordering
The list of direct link dependencies for a target is computed from an initial ordered list in its
LINK_LIBRARIES <#prop_tgt:LINK_LIBRARIES> target property. For each item, additional direct link
dependencies are discovered from its direct and transitive INTERFACE_LINK_LIBRARIES_DIRECT usage
requirements. Each discovered item is injected before the item that specified it. However, a discovered
item is added at most once, and only if it did not appear anywhere in the initial list. This gives
LINK_LIBRARIES <#prop_tgt:LINK_LIBRARIES> control over ordering of those direct link dependencies that it
explicitly specifies.

Once all direct link dependencies have been collected, items named by all of their
INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE <#prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE> usage
requirements are removed from the final list. This does not affect the order of the items that remain.

Example: Static Plugins
Consider a static library Foo that provides a static plugin FooPlugin to consuming application
executables, where the implementation of the plugin depends on Foo and other things. In this case, the
application should link to FooPlugin directly, before Foo. However, the application author only knows
about Foo. We can express this as follows:

# Core library used by other components.
add_library(Core STATIC core.cpp)

# Foo is a static library for use by applications.
# Implementation of Foo depends on Core.
add_library(Foo STATIC foo.cpp foo_plugin_helper.cpp)
target_link_libraries(Foo PRIVATE Core)

# Extra parts of Foo for use by its static plugins.
# Implementation of Foo's extra parts depends on both Core and Foo.
add_library(FooExtras STATIC foo_extras.cpp)
target_link_libraries(FooExtras PRIVATE Core Foo)

# The Foo library has an associated static plugin
# that should be linked into the final executable.
# Implementation of the plugin depends on Core, Foo, and FooExtras.
add_library(FooPlugin STATIC foo_plugin.cpp)
target_link_libraries(FooPlugin PRIVATE Core Foo FooExtras)

# An app that links Foo should link Foo's plugin directly.
set_property(TARGET Foo PROPERTY INTERFACE_LINK_LIBRARIES_DIRECT FooPlugin)

# An app does not need to link Foo directly because the plugin links it.
set_property(TARGET Foo PROPERTY INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE Foo)

An application app only needs to specify that it links to Foo:

add_executable(app main.cpp)
target_link_libraries(app PRIVATE Foo)

The INTERFACE_LINK_LIBRARIES_DIRECT target property on Foo tells CMake to pretend that app also links
directly to FooPlugin. The INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE target property on Foo tells CMake to
pretend that app did not link directly to Foo. Instead, Foo will be linked as a dependency of FooPlugin.
The final link line for app will link the libraries in the following order:

• FooPlugin as a direct link dependency of app (via Foo's usage requirements).

• FooExtras as a dependency of FooPlugin.

• Foo as a dependency of FooPlugin and FooExtras.

• Core as a dependency of FooPlugin, FooExtras, and Foo.

Note that without the INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE target property, Foo would be linked twice:
once as a direct dependency of app, and once as a dependency of FooPlugin.

Example: Opt-In Static Plugins
In the above Example: Static Plugins, the app executable specifies that it links directly to Foo. In a
real application, there might be an intermediate library:

add_library(app_impl STATIC app_impl.cpp)
target_link_libraries(app_impl PRIVATE Foo)

add_executable(app main.cpp)
target_link_libraries(app PRIVATE app_impl)

In this case we do not want Foo's INTERFACE_LINK_LIBRARIES_DIRECT and
INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE target properties to affect the direct dependencies of app_impl.
To avoid this, we can revise the property values to make their effects opt-in:

# An app that links Foo should link Foo's plugin directly.
set_property(TARGET Foo PROPERTY INTERFACE_LINK_LIBRARIES_DIRECT
"$<$<BOOL:$<TARGET_PROPERTY:FOO_STATIC_PLUGINS>>:FooPlugin>"
)

# An app does not need to link Foo directly because the plugin links it.
set_property(TARGET Foo PROPERTY INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE
"$<$<BOOL:$<TARGET_PROPERTY:FOO_STATIC_PLUGINS>>:Foo>"
)

Now, the app executable can opt-in to get Foo's plugin(s):

set_property(TARGET app PROPERTY FOO_STATIC_PLUGINS 1)

The final link line for app will now link the libraries in the following order:

• FooPlugin as a direct link dependency of app (via Foo's usage requirements).

• app_impl as a direct link dependency of app.

• FooExtras as a dependency of FooPlugin.

• Foo as a dependency of app_impl, FooPlugin, and FooExtras.

• Core as a dependency of FooPlugin, FooExtras, and Foo.

INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE
Added in version 3.24.

List of libraries that consumers of this library should not treat as direct link dependencies.

This target property may be set to exclude items from a dependent target's final set of direct link
dependencies. This property is processed after the INTERFACE_LINK_LIBRARIES_DIRECT <#
prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT> target property of all other dependencies of the dependent
target, so exclusion from direct link dependence takes priority over inclusion.

The initial set of a dependent target's direct link dependencies is specified by its LINK_LIBRARIES <#
prop_tgt:LINK_LIBRARIES> target property. Indirect link dependencies are specified by the transitive
closure of the direct link dependencies' INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES>
properties. Any link dependency may specify additional direct link dependencies using the
INTERFACE_LINK_LIBRARIES_DIRECT <#prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT> target property. The set of
direct link dependencies is then filtered to exclude items named by any dependency's
INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE target property.

Excluding an item from a dependent target's direct link dependencies does not mean the dependent target
won't link the item. The item may still be linked as an indirect link dependency via the
INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES> property on other dependencies.

The value of INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE may use generator expressions <#
manual:cmake-generator-expressions(7)>.

Note:
The INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE target property is intended for advanced use cases such as
injection of static plugins into a consuming executable. It should not be used as a substitute for
organizing normal calls to target_link_libraries() <#command:target_link_libraries>.

See the INTERFACE_LINK_LIBRARIES_DIRECT <#prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT> target property
documentation for more details and examples.

INTERFACE_LINK_OPTIONS
Added in version 3.13.

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: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.

Contents of INTERFACE_LINK_OPTIONS may use "generator expressions" with the syntax $<...>. See the
cmake-generator-expressions(7) <#manual:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual: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 <#prop_tgt:POSITION_INDEPENDENT_CODE> property to ON. If this property
is set to ON, then the POSITION_INDEPENDENT_CODE <#prop_tgt: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 <#prop_tgt: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 <#
prop_tgt: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:cmake-generator-expressions(7)> manual for available
expressions. See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> manual for more on defining
buildsystem properties.

INTERFACE_PRECOMPILE_HEADERS
Added in version 3.16.

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: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() <#command: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:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> manual for more on defining buildsystem
properties.

INTERFACE_SOURCES
Added in version 3.1.

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:target_sources> command populates this property with values given to the
PUBLIC and INTERFACE keywords. Projects may also get and set the property directly.

Contents of INTERFACE_SOURCES may use "generator expressions" with the syntax $<...>. See the
cmake-generator-expressions(7) <#manual:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual: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. Additionally, system include directories are searched
after normal include directories regardless of the order specified.

When the target_include_directories() <#command:target_include_directories> command is given the SYSTEM
keyword, it populates this property with values provided after 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 directories which otherwise would be used in a non-system manner. This can
appear similar to duplication, so prefer the high-level target_include_directories() <#
command:target_include_directories> command with the SYSTEM keyword and avoid setting the property
directly.

When target dependencies are specified using target_link_libraries() <#command: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:cmake-generator-expressions(7)> manual for available
expressions. See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> manual for more on defining
buildsystem properties.

INTERPROCEDURAL_OPTIMIZATION
Enable interprocedural optimization for a target.

If set to true, enables interprocedural optimizations if they are known to be supported <#
module:CheckIPOSupported> by the compiler. Depending on value of policy CMP0069 <#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:CMAKE_INTERPROCEDURAL_OPTIMIZATION> variable if it is set when a target is created.

There is also the per-configuration INTERPROCEDURAL_OPTIMIZATION_<CONFIG> <#
prop_tgt:INTERPROCEDURAL_OPTIMIZATION_<CONFIG>> target property, which overrides
INTERPROCEDURAL_OPTIMIZATION if it is set.

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

This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION <#
prop_tgt: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:CMAKE_INTERPROCEDURAL_OPTIMIZATION_<CONFIG>> variable if it is set when a target is created.

ISPC_HEADER_DIRECTORY
Added in version 3.19.

Specify relative output directory for ISPC headers provided by the target.

If the target contains ISPC source files, this specifies the directory in which the generated headers
will be placed. Relative paths are treated with respect to the value of CMAKE_CURRENT_BINARY_DIR <#
variable:CMAKE_CURRENT_BINARY_DIR>. When this property is not set, the headers will be placed a generator
defined build directory. If the variable CMAKE_ISPC_HEADER_DIRECTORY <#
variable:CMAKE_ISPC_HEADER_DIRECTORY> is set when a target is created its value is used to initialize
this property.

ISPC_HEADER_SUFFIX
Added in version 3.19.2.

Specify output suffix to be used for ISPC generated headers provided by the target.

This property is initialized by the value of the CMAKE_ISPC_HEADER_SUFFIX <#
variable:CMAKE_ISPC_HEADER_SUFFIX> variable if it is set when a target is created.

If the target contains ISPC source files, this specifies the header suffix to be used for the generated
headers.

The default value is _ispc.h.

ISPC_INSTRUCTION_SETS
Added in version 3.19.

List of instruction set architectures to generate code for.

This property is initialized by the value of the CMAKE_ISPC_INSTRUCTION_SETS <#
variable:CMAKE_ISPC_INSTRUCTION_SETS> variable if it is set when a target is created.

The ISPC_INSTRUCTION_SETS target property must be used when generating for multiple instruction sets so
that CMake can track what object files will be generated.

Examples
set_property(TARGET tgt PROPERTY ISPC_INSTRUCTION_SETS avx2-i32x4 avx512skx-i32x835)

Generates code for avx2 and avx512skx target architectures.

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 <#
prop_gbl: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 <#variable: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 <#
prop_gbl: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 <#variable:CMAKE_JOB_POOL_LINK>.

JOB_POOL_PRECOMPILE_HEADER
Added in version 3.17.

Ninja only: Pool used for generating pre-compiled headers.

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

For instance:

set_property(TARGET myexe PROPERTY JOB_POOL_PRECOMPILE_HEADER two_jobs)

This property is initialized by the value of CMAKE_JOB_POOL_PRECOMPILE_HEADER <#
variable:CMAKE_JOB_POOL_PRECOMPILE_HEADER>.

If neither JOB_POOL_PRECOMPILE_HEADER nor CMAKE_JOB_POOL_PRECOMPILE_HEADER <#
variable:CMAKE_JOB_POOL_PRECOMPILE_HEADER> are set then JOB_POOL_COMPILE <#prop_tgt:JOB_POOL_COMPILE>
will be used for this task.

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

Target label semantics are currently unspecified.

<LANG>_CLANG_TIDY
Added in version 3.6.

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

Specify a semicolon-separated list <#cmake-language-lists> containing a command line for the clang-tidy
tool. The Makefile Generators <#makefile-generators> and the Ninja <#generator:Ninja> generator will run
this tool along with the compiler and report a warning if the tool reports any problems.

The specified clang-tidy command line will be invoked with additional arguments specifying the source
file and, after --, the full compiler command line.

Changed in version 3.25: If the specified clang-tidy command line includes the -p option, it will be
invoked without -- and the full compiler command line. clang-tidy will look up the source file in the
specified compiler commands database.

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

Added in version 3.27: This property supports generator expressions <#
manual:cmake-generator-expressions(7)>.

Added in version 3.27: SKIP_LINTING <#prop_sf:SKIP_LINTING> can be set on individual source files to
exclude them from the linting tools defined by <LANG>_CPPLINT <#prop_tgt:<LANG>_CPPLINT>,
<LANG>_CLANG_TIDY, <LANG>_CPPCHECK <#prop_tgt:<LANG>_CPPCHECK>, and <LANG>_INCLUDE_WHAT_YOU_USE <#
prop_tgt:<LANG>_INCLUDE_WHAT_YOU_USE>. When SKIP_LINTING <#prop_sf:SKIP_LINTING> is set to true on a
source file, those tools will not be run on that specific file.

<LANG>_CLANG_TIDY_EXPORT_FIXES_DIR
Added in version 3.26.

This property is implemented only when <LANG> is C, CXX, OBJC or OBJCXX, and only has an effect when
<LANG>_CLANG_TIDY <#prop_tgt:<LANG>_CLANG_TIDY> is set.

Specify a directory for the clang-tidy tool to put .yaml files containing its suggested changes in. This
can be used for automated mass refactoring by clang-tidy. Each object file that gets compiled will have a
corresponding .yaml file in this directory. After the build is completed, you can run
clang-apply-replacements on this directory to simultaneously apply all suggested changes to the code
base. If this property is not an absolute directory, it is assumed to be relative to the target's binary
directory. This property should be preferred over adding an --export-fixes or --fix argument directly to
the <LANG>_CLANG_TIDY <#prop_tgt:<LANG>_CLANG_TIDY> property.

When this property is set, CMake takes ownership of the specified directory, and may create, modify, or
delete files and directories within the directory at any time during configure or build time. Users
should use a dedicated directory for exporting clang-tidy fixes to avoid having files deleted or
overwritten by CMake. Users should not create, modify, or delete files in this directory.

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

<LANG>_COMPILER_LAUNCHER
Added in version 3.4.

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

Specify a semicolon-separated list <#cmake-language-lists> containing a command line for a compiler
launching tool. The Makefile Generators <#makefile-generators> and the Ninja <#generator: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:CMAKE_<LANG>_COMPILER_LAUNCHER> variable if it is set when a target is created.

Added in version 3.25: The property value may use generator expressions <#
manual:cmake-generator-expressions(7)>.

<LANG>_CPPCHECK
Added in version 3.10.

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

Specify a semicolon-separated list <#cmake-language-lists> containing a command line for the cppcheck
static analysis tool. The Makefile Generators <#makefile-generators> and the Ninja <#generator: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:CMAKE_<LANG>_CPPCHECK>
variable if it is set when a target is created.

Added in version 3.27: This property supports generator expressions <#
manual:cmake-generator-expressions(7)>.

Added in version 3.27: SKIP_LINTING <#prop_sf:SKIP_LINTING> can be set on individual source files to
exclude them from the linting tools defined by <LANG>_CPPLINT <#prop_tgt:<LANG>_CPPLINT>,
<LANG>_CLANG_TIDY <#prop_tgt:<LANG>_CLANG_TIDY>, <LANG>_CPPCHECK, and <LANG>_INCLUDE_WHAT_YOU_USE <#
prop_tgt:<LANG>_INCLUDE_WHAT_YOU_USE>. When SKIP_LINTING <#prop_sf:SKIP_LINTING> is set to true on a
source file, those tools will not be run on that specific file.

<LANG>_CPPLINT
Added in version 3.8.

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

Specify a semicolon-separated list <#cmake-language-lists> containing a command line for the cpplint
style checker. The Makefile Generators <#makefile-generators> and the Ninja <#generator: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:CMAKE_<LANG>_CPPLINT>
variable if it is set when a target is created.

Added in version 3.27: This property supports generator expressions <#
manual:cmake-generator-expressions(7)>.

Added in version 3.27: SKIP_LINTING <#prop_sf:SKIP_LINTING> can be set on individual source files to
exclude them from the linting tools defined by <LANG>_CPPLINT, <LANG>_CLANG_TIDY <#
prop_tgt:<LANG>_CLANG_TIDY>, <LANG>_CPPCHECK <#prop_tgt:<LANG>_CPPCHECK>, and <LANG>_INCLUDE_WHAT_YOU_USE
<#prop_tgt:<LANG>_INCLUDE_WHAT_YOU_USE>. When SKIP_LINTING <#prop_sf:SKIP_LINTING> is set to true on a
source file, those tools will not be run on that specific file.

<LANG>_EXTENSIONS
The variations are:

• C_EXTENSIONS <#prop_tgt:C_EXTENSIONS>

• CXX_EXTENSIONS <#prop_tgt:CXX_EXTENSIONS>

• CUDA_EXTENSIONS <#prop_tgt:CUDA_EXTENSIONS>

• HIP_EXTENSIONS <#prop_tgt:HIP_EXTENSIONS>

• OBJC_EXTENSIONS <#prop_tgt:OBJC_EXTENSIONS>

• OBJCXX_EXTENSIONS <#prop_tgt:OBJCXX_EXTENSIONS>

These properties specify whether compiler-specific extensions are requested.

These properties are initialized by the value of the CMAKE_<LANG>_EXTENSIONS <#
variable:CMAKE_<LANG>_EXTENSIONS> variable if it is set when a target is created and otherwise by the
value of CMAKE_<LANG>_EXTENSIONS_DEFAULT <#variable:CMAKE_<LANG>_EXTENSIONS_DEFAULT> (see CMP0128 <#
policy:CMP0128>).

For supported CMake versions see the respective pages. To control language standard versions see
<LANG>_STANDARD <#prop_tgt:<LANG>_STANDARD>.

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

<LANG>_INCLUDE_WHAT_YOU_USE
Added in version 3.3.

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

Specify a semicolon-separated list <#cmake-language-lists> containing a command line for the
include-what-you-use tool. The Makefile Generators <#makefile-generators> and the Ninja <#
generator: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:CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE> variable if it is set when a target is created.

Added in version 3.27: This property supports generator expressions <#
manual:cmake-generator-expressions(7)>.

Added in version 3.27: SKIP_LINTING <#prop_sf:SKIP_LINTING> can be set on individual source files to
exclude them from the linting tools defined by <LANG>_CPPLINT <#prop_tgt:<LANG>_CPPLINT>,
<LANG>_CLANG_TIDY <#prop_tgt:<LANG>_CLANG_TIDY>, <LANG>_CPPCHECK <#prop_tgt:<LANG>_CPPCHECK>, and
<LANG>_INCLUDE_WHAT_YOU_USE. When SKIP_LINTING <#prop_sf:SKIP_LINTING> is set to true on a source file,
those tools will not be run on that specific file.

<LANG>_LINKER_LAUNCHER
Added in version 3.21.

This property is implemented only when <LANG> is C, CXX, OBJC, or OBJCXX

Specify a semicolon-separated list <#cmake-language-lists> containing a command line for a linker
launching tool. The Makefile Generators <#makefile-generators> and the Ninja <#generator:Ninja> generator
will run this tool and pass the linker and its arguments to the tool. This is useful for tools such as
static analyzers.

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

Added in version 3.27: The property value may use generator expressions <#
manual:cmake-generator-expressions(7)>.

<LANG>_STANDARD
The variations are:

• C_STANDARD <#prop_tgt:C_STANDARD>

• CXX_STANDARD <#prop_tgt:CXX_STANDARD>

• CUDA_STANDARD <#prop_tgt:CUDA_STANDARD>

• HIP_STANDARD <#prop_tgt:HIP_STANDARD>

• OBJC_STANDARD <#prop_tgt:OBJC_STANDARD>

• OBJCXX_STANDARD <#prop_tgt:OBJCXX_STANDARD>

These properties specify language standard versions which are requested. When a newer standard is
specified than is supported by the compiler, then it will fallback to the latest supported standard. This
"decay" behavior may be controlled with the <LANG>_STANDARD_REQUIRED <#prop_tgt:<LANG>_STANDARD_REQUIRED>
target property.

Note that the actual language standard used may be higher than that specified by <LANG>_STANDARD,
regardless of the value of <LANG>_STANDARD_REQUIRED <#prop_tgt:<LANG>_STANDARD_REQUIRED>. In particular,
usage requirements <#target-usage-requirements> or the use of compile features <#
manual:cmake-compile-features(7)> can raise the required language standard above what <LANG>_STANDARD
specifies.

These properties are initialized by the value of the CMAKE_<LANG>_STANDARD <#
variable:CMAKE_<LANG>_STANDARD> variable if it is set when a target is created.

For supported values and CMake versions see the respective pages. To control compiler-specific
extensions see <LANG>_EXTENSIONS <#prop_tgt:<LANG>_EXTENSIONS>.

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

<LANG>_STANDARD_REQUIRED
The variations are:

• C_STANDARD_REQUIRED <#prop_tgt:C_STANDARD_REQUIRED>

• CXX_STANDARD_REQUIRED <#prop_tgt:CXX_STANDARD_REQUIRED>

• CUDA_STANDARD_REQUIRED <#prop_tgt:CUDA_STANDARD_REQUIRED>

• HIP_STANDARD_REQUIRED <#prop_tgt:HIP_STANDARD_REQUIRED>

• OBJC_STANDARD_REQUIRED <#prop_tgt:OBJC_STANDARD_REQUIRED>

• OBJCXX_STANDARD_REQUIRED <#prop_tgt:OBJCXX_STANDARD_REQUIRED>

These properties specify whether the value of <LANG>_STANDARD <#prop_tgt:<LANG>_STANDARD> is a
requirement. When false or unset, the <LANG>_STANDARD <#prop_tgt:<LANG>_STANDARD> target property is
treated as optional and may "decay" to a previous standard if the requested standard is not available.
When <LANG>_STANDARD_REQUIRED is set to true, <LANG>_STANDARD <#prop_tgt:<LANG>_STANDARD> becomes a hard
requirement and a fatal error will be issued if that requirement cannot be met.

Note that the actual language standard used may be higher than that specified by <LANG>_STANDARD <#
prop_tgt:<LANG>_STANDARD>, regardless of the value of <LANG>_STANDARD_REQUIRED. In particular, usage
requirements <#target-usage-requirements> or the use of compile features <#
manual:cmake-compile-features(7)> can raise the required language standard above what <LANG>_STANDARD <#
prop_tgt:<LANG>_STANDARD> specifies.

These properties are initialized by the value of the CMAKE_<LANG>_STANDARD_REQUIRED <#
variable:CMAKE_<LANG>_STANDARD_REQUIRED> variable if it is set when a target is created.

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

<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 <#policy:CMP0063>).

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

LIBRARY_OUTPUT_DIRECTORY
Output directory in which to build LIBRARY <#library-output-artifacts> target files.

This property specifies the directory into which library target files should be built. The property
value may use generator expressions <#manual:cmake-generator-expressions(7)>. Multi-configuration
generators (Visual Studio <#visual-studio-generators>, Xcode <#generator:Xcode>, Ninja Multi-Config <#
generator:Ninja Multi-Config>) 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_LIBRARY_OUTPUT_DIRECTORY <#
variable:CMAKE_LIBRARY_OUTPUT_DIRECTORY> variable if it is set when a target is created.

See also the LIBRARY_OUTPUT_DIRECTORY_<CONFIG> <#prop_tgt:LIBRARY_OUTPUT_DIRECTORY_<CONFIG>> target
property.

LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
Per-configuration output directory for LIBRARY <#library-output-artifacts> target files.

This is a per-configuration version of the LIBRARY_OUTPUT_DIRECTORY <#prop_tgt:LIBRARY_OUTPUT_DIRECTORY>
target property, but multi-configuration generators (Visual Studio Generators <#
visual-studio-generators>, Xcode <#generator: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: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 <#
manual:cmake-generator-expressions(7)>.

LIBRARY_OUTPUT_NAME
Output name for LIBRARY <#library-output-artifacts> target files.

This property specifies the base name for library target files. It overrides OUTPUT_NAME <#
prop_tgt:OUTPUT_NAME> and OUTPUT_NAME_<CONFIG> <#prop_tgt:OUTPUT_NAME_<CONFIG>> properties.

See also the LIBRARY_OUTPUT_NAME_<CONFIG> <#prop_tgt:LIBRARY_OUTPUT_NAME_<CONFIG>> target property.

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

This is the configuration-specific version of the LIBRARY_OUTPUT_NAME <#prop_tgt:LIBRARY_OUTPUT_NAME>
target property.

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 <#generator:Ninja> and Makefile Generators <#
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:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> manual for more on defining buildsystem
properties.

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 CMAKE_LINK_DEPENDS_NO_SHARED <#
variable:CMAKE_LINK_DEPENDS_NO_SHARED> variable if it is set when a target is created.

LINK_DIRECTORIES
Added in version 3.13.

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

This property holds a semicolon-separated list <#cmake-language-lists> of directories specified so far
for its target. Use the target_link_directories() <#command:target_link_directories> command to append
more search directories.

This property is initialized by the LINK_DIRECTORIES <#prop_dir: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:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> manual for more on defining buildsystem
properties.

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 <#prop_tgt:STATIC_LIBRARY_OPTIONS> or
STATIC_LIBRARY_FLAGS <#prop_tgt: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> <#prop_tgt:LINK_FLAGS_<CONFIG>> will add to the configuration <CONFIG>, for
example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO, ...

Note:
This property has been superseded by LINK_OPTIONS <#prop_tgt:LINK_OPTIONS> property.

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

This is the configuration-specific version of LINK_FLAGS <#prop_tgt:LINK_FLAGS>.

Note:
This property has been superseded by LINK_OPTIONS <#prop_tgt:LINK_OPTIONS> property.

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 <#prop_tgt: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: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: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 <#prop_tgt:INTERFACE_LINK_LIBRARIES> property
if policy CMP0022 <#policy:CMP0022> is NEW.

This property is deprecated. Use INTERFACE_LINK_LIBRARIES <#prop_tgt: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.

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

This is the configuration-specific version of LINK_INTERFACE_LIBRARIES <#
prop_tgt: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 <#prop_tgt:INTERFACE_LINK_LIBRARIES> property
if policy CMP0022 <#policy:CMP0022> is NEW.

This property is deprecated. Use INTERFACE_LINK_LIBRARIES <#prop_tgt: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.

LINK_INTERFACE_MULTIPLICITY
Repetition count for STATIC libraries with cyclic dependencies.

When linking to a STATIC library target with cyclic dependencies the linker may need to scan more than
once through the archives in the strongly connected component of the dependency graph. CMake by default
constructs the link line so that the linker will scan through the component at least twice. This
property specifies the minimum number of scans if it is larger than the default. CMake uses the largest
value specified by any target in a component.

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

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

LINK_LIBRARIES
List of direct link dependencies.

This property specifies the list of libraries or targets which will be used for linking. In addition to
accepting values from the target_link_libraries() <#command:target_link_libraries> command, values may be
set directly on any target using the set_property() <#command:set_property> command.

The value of this property is used by the generators to construct the link rule for the target. The
direct link dependencies are linked first, followed by indirect dependencies from the transitive closure
of the direct dependencies' INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES> properties.
See policy CMP0022 <#policy:CMP0022>.

Contents of LINK_LIBRARIES may use generator expressions <#manual:cmake-generator-expressions(7)> with
the syntax $<...>. Policy CMP0131 <#policy:CMP0131> affects the behavior of the LINK_ONLY <#
genex:LINK_ONLY> generator expression for this property.

See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> manual for more on defining buildsystem
properties.

In advanced use cases, the list of direct link dependencies specified by this property may be updated by
usage requirements from dependencies. See the INTERFACE_LINK_LIBRARIES_DIRECT <#
prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT> and INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE <#
prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE> target properties.

See the CMAKE_LINK_LIBRARIES_STRATEGY <#variable:CMAKE_LINK_LIBRARIES_STRATEGY> variable and
corresponding LINK_LIBRARIES_STRATEGY <#prop_tgt:LINK_LIBRARIES_STRATEGY> target property for details on
how CMake orders direct link dependencies on linker command lines.

LINK_LIBRARIES_ONLY_TARGETS
Added in version 3.23.

Enforce that link items that can be target names are actually existing targets.

Set this property to a true value to enable additional checks on the contents of the LINK_LIBRARIES <#
prop_tgt:LINK_LIBRARIES> and INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES> target
properties, typically populated by target_link_libraries() <#command:target_link_libraries>. Checks are
also applied to libraries added to a target through the INTERFACE_LINK_LIBRARIES_DIRECT <#
prop_tgt:INTERFACE_LINK_LIBRARIES_DIRECT> properties of its dependencies. CMake will verify that link
items that might be target names actually name existing targets. An item is considered a possible target
name if:

• it does not contain a / or \, and

• it does not start in -, and

• (for historical reasons) it does not start in $ or `.

This property is initialized by the value of the CMAKE_LINK_LIBRARIES_ONLY_TARGETS <#
variable:CMAKE_LINK_LIBRARIES_ONLY_TARGETS> variable when a non-imported target is created. The property
may be explicitly enabled on an imported target to check its link interface.

In the following example, CMake will halt with an error at configure time because miLib is not a target:

set(CMAKE_LINK_LIBRARIES_ONLY_TARGETS ON)
add_library(myLib STATIC myLib.c)
add_executable(myExe myExe.c)
target_link_libraries(myExe PRIVATE miLib) # typo for myLib

In order to link toolchain-provided libraries by name while still enforcing LINK_LIBRARIES_ONLY_TARGETS,
use an imported <#imported-targets> Interface Library <#interface-libraries> with the IMPORTED_LIBNAME <#
prop_tgt:IMPORTED_LIBNAME> target property:

add_library(toolchain::m INTERFACE IMPORTED)
set_property(TARGET toolchain::m PROPERTY IMPORTED_LIBNAME "m")
target_link_libraries(myExe PRIVATE toolchain::m)

See also policy CMP0028 <#policy:CMP0028>.

Note:
If INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES> contains generator expressions, its
actual list of link items may depend on the type and properties of the consuming target. In such
cases CMake may not always detect names of missing targets that only appear for specific consumers. A
future version of CMake with improved heuristics may start triggering errors on projects accepted by
previous versions of CMake.

LINK_LIBRARIES_STRATEGY
Added in version 3.31.

Specify a strategy for ordering a target's direct link dependencies on linker command lines. This
property is initialized by the value of the CMAKE_LINK_LIBRARIES_STRATEGY <#
variable:CMAKE_LINK_LIBRARIES_STRATEGY> variable if it is set when a target is created.

CMake generates a target's link line using its Target Link Properties <#target-link-properties>. In
particular, the LINK_LIBRARIES <#prop_tgt:LINK_LIBRARIES> target property records the target's direct
link dependencies, typically populated by calls to target_link_libraries() <#
command:target_link_libraries>. Indirect link dependencies are propagated from those entries of
LINK_LIBRARIES <#prop_tgt:LINK_LIBRARIES> that name library targets by following the transitive closure
of their INTERFACE_LINK_LIBRARIES <#prop_tgt:INTERFACE_LINK_LIBRARIES> properties. CMake supports
multiple strategies for nominally ordering direct and indirect link dependencies, which are then filtered
for Toolchain-Specific Behavior.

Consider this example for the strategies below:

add_library(A STATIC ...)
add_library(B STATIC ...)
add_library(C STATIC ...)
add_executable(main ...)
target_link_libraries(B PRIVATE A)
target_link_libraries(C PRIVATE A)
target_link_libraries(main PRIVATE A B C)

The supported strategies are:

REORDER_MINIMALLY
Entries of LINK_LIBRARIES <#prop_tgt:LINK_LIBRARIES> always appear first and in their original
order. Indirect link dependencies not satisfied by the original entries may be reordered and
de-duplicated with respect to one another, but are always appended after the original entries.
This may result in less efficient link lines, but gives projects control of ordering among
independent entries. Such control may be important when intermixing link flags with libraries, or
when multiple libraries provide a given symbol.

This is the default.

In the above example, this strategy computes a link line for main by starting with its original
entries A B C, and then appends another A to satisfy the dependencies of B and C on A. The
nominal order produced by this strategy is A B C A.

Note that additional filtering for Toolchain-Specific Behavior may de-duplicate A on the actual
linker invocation in the generated build system, resulting in either A B C or B C A.

REORDER_FREELY
Entries of LINK_LIBRARIES <#prop_tgt:LINK_LIBRARIES> may be reordered, de-duplicated, and
intermixed with indirect link dependencies. This may result in more efficient link lines, but
does not give projects any control of ordering among independent entries.

In the above example, this strategy computes a link line for main by re-ordering its original
entries A B C to satisfy the dependencies of B and C on A. The nominal order produced by this
strategy is B C A.

Toolchain-Specific Behavior
After one of the above strategies produces a nominal order among direct and indirect link dependencies,
the actual linker invocation in the generated build system may de-duplicate entries based on
platform-specific requirements and linker capabilities. See policy CMP0156 <#policy:CMP0156>.

For example, if the REORDER_MINIMALLY strategy produces A B C A, the actual link line may de-duplicate A
as follows:

• If A is a static library and the linker re-scans automatically, the first occurrence is kept, resulting
in A B C. See policy CMP0179 <#policy:CMP0179>

• If A is a shared library on Windows, the first occurrence is kept, resulting in A B C.

• If A is a shared library on macOS or UNIX platforms, the last occurrence is kept, resulting in B C A.

LINK_LIBRARY_OVERRIDE
Added in version 3.24.

Override the library features associated with libraries from LINK_LIBRARY <#genex:LINK_LIBRARY> generator
expressions. This can be used to resolve incompatible library features that result from specifying
different features for the same library in different LINK_LIBRARY <#genex:LINK_LIBRARY> generator
expressions.

This property supports overriding multiple libraries and features. It expects a semicolon-separated list
<#cmake-language-lists>, where each list item has the following form:

feature[,link-item]*

For each comma-separated link-item, any existing library feature associated with it will be ignored for
the target this property is set on. The item will instead be associated with the specified feature.
Each link-item can be anything that would be accepted as part of a library-list in a LINK_LIBRARY <#
genex:LINK_LIBRARY> generator expression.

add_library(lib1 ...)
add_library(lib2 ...)
add_library(lib3 ...)

target_link_libraries(lib1 PUBLIC "$<LINK_LIBRARY:feature1,external>")
target_link_libraries(lib2 PUBLIC "$<LINK_LIBRARY:feature2,lib1>")
target_link_libraries(lib3 PRIVATE lib1 lib2)

# lib1 is associated with both feature2 and no feature. Without any override,
# this would result in a fatal error at generation time for lib3.
# Define an override to resolve the incompatible feature associations.
set_property(TARGET lib3 PROPERTY LINK_LIBRARY_OVERRIDE "feature2,lib1,external")

# lib1 and external will now be associated with feature2 instead when linking lib3

It is also possible to override any feature with the pre-defined DEFAULT library feature. This
effectively discards any feature for that link item, for that target only (lib3 in this example):

# When linking lib3, discard any library feature for lib1, and use feature2 for external
set_property(TARGET lib3 PROPERTY LINK_LIBRARY_OVERRIDE
"DEFAULT,lib1"
"feature2,external"
)

The above example also demonstrates how to specify different feature overrides for different link items.
See the LINK_LIBRARY_OVERRIDE_<LIBRARY> <#prop_tgt:LINK_LIBRARY_OVERRIDE_<LIBRARY>> target property for
an alternative way of overriding library features for individual libraries, which may be simpler in some
cases. If both properties are defined and specify an override for the same link item,
LINK_LIBRARY_OVERRIDE_<LIBRARY> <#prop_tgt:LINK_LIBRARY_OVERRIDE_<LIBRARY>> takes precedence over
LINK_LIBRARY_OVERRIDE.

Contents of LINK_LIBRARY_OVERRIDE may use generator expressions <#manual:cmake-generator-expressions(7)>.

For more information about library features, see the CMAKE_<LANG>_LINK_LIBRARY_USING_<FEATURE> <#
variable:CMAKE_<LANG>_LINK_LIBRARY_USING_<FEATURE>> and CMAKE_LINK_LIBRARY_USING_<FEATURE> <#
variable:CMAKE_LINK_LIBRARY_USING_<FEATURE>> variables.

LINK_LIBRARY_OVERRIDE_<LIBRARY>
Added in version 3.24.

Override the library feature associated with <LIBRARY> from LINK_LIBRARY <#genex:LINK_LIBRARY> generator
expressions. This can be used to resolve incompatible library features that result from specifying
different features for <LIBRARY> in different LINK_LIBRARY <#genex:LINK_LIBRARY> generator expressions.

When set on a target, this property holds a single library feature name, which will be applied to
<LIBRARY> when linking that target.

add_library(lib1 ...)
add_library(lib2 ...)
add_library(lib3 ...)

target_link_libraries(lib1 PUBLIC "$<LINK_LIBRARY:feature1,external>")
target_link_libraries(lib2 PUBLIC "$<LINK_LIBRARY:feature2,lib1>")
target_link_libraries(lib3 PRIVATE lib1 lib2)

# lib1 will now be associated with feature2 instead when linking lib3

It is also possible to override any feature with the pre-defined DEFAULT library feature. This
effectively discards any feature for that link item, for that target only (lib3 in this example):

# When linking lib3, discard any library feature for lib1
set_property(TARGET lib3 PROPERTY LINK_LIBRARY_OVERRIDE_lib1 DEFAULT)

See the LINK_LIBRARY_OVERRIDE <#prop_tgt:LINK_LIBRARY_OVERRIDE> target property for an alternative way of
overriding library features for multiple libraries at once. If both properties are defined and specify
an override for the same link item, LINK_LIBRARY_OVERRIDE_<LIBRARY> takes precedence over
LINK_LIBRARY_OVERRIDE <#prop_tgt:LINK_LIBRARY_OVERRIDE>.

Contents of LINK_LIBRARY_OVERRIDE_<LIBRARY> may use generator expressions <#
manual:cmake-generator-expressions(7)>.

LINK_OPTIONS
Added in version 3.13.

List of options to use for the link step of shared library, module and executable targets as well as the
device link step. Targets that are static libraries need to use the STATIC_LIBRARY_OPTIONS <#
prop_tgt:STATIC_LIBRARY_OPTIONS> target property.

These options are used for both normal linking and device linking (see policy CMP0105 <#policy:CMP0105>).
To control link options for normal and device link steps, $<HOST_LINK> <#genex:HOST_LINK> and
$<DEVICE_LINK> <#genex:DEVICE_LINK> generator expressions can be used.

This property holds a semicolon-separated list <#cmake-language-lists> of options specified so far for
its target. Use the target_link_options() <#command:target_link_options> command to append more options.

This property is initialized by the LINK_OPTIONS <#prop_dir: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:cmake-generator-expressions(7)> manual for available expressions.
See the cmake-buildsystem(7) <#manual:cmake-buildsystem(7)> manual for more on defining buildsystem
properties.

Note:
This property must be used in preference to LINK_FLAGS <#prop_tgt:LINK_FLAGS> property.

Host And Device Specific Link Options
Added in version 3.18: When a device link step is involved, which is controlled by
CUDA_SEPARABLE_COMPILATION <#prop_tgt:CUDA_SEPARABLE_COMPILATION> and CUDA_RESOLVE_DEVICE_SYMBOLS <#
prop_tgt:CUDA_RESOLVE_DEVICE_SYMBOLS> properties and policy CMP0105 <#policy:CMP0105>, the raw options
will be delivered to the host and device link steps (wrapped in -Xcompiler or equivalent for device
link). Options wrapped with $<DEVICE_LINK:...> <#genex:DEVICE_LINK> generator expression will be used
only for the device link step. Options wrapped with $<HOST_LINK:...> <#genex:HOST_LINK> generator
expression will be used only for the host link step.

Handling Compiler Driver Differences
To pass options to the linker tool, each compiler driver has its own syntax. The LINKER: prefix and ,
separator can be used to specify, in a portable way, options to pass to the linker tool. LINKER: is
replaced by the appropriate driver option and , by the appropriate driver separator. The driver prefix
and driver separator are given by the values of the CMAKE_<LANG>_LINKER_WRAPPER_FLAG <#
variable:CMAKE_<LANG>_LINKER_WRAPPER_FLAG> and CMAKE_<LANG>_LINKER_WRAPPER_FLAG_SEP <#
variable:CMAKE_<LANG>_LINKER_WRAPPER_FLAG_SEP> variables.

For example, "LINKER:-z,defs" becomes -Xlinker -z -Xlinker defs for Clang and -Wl,-z,defs for GNU GCC.

The LINKER: prefix can be specified as part of a SHELL: prefix expression.

The LINKER: prefix supports, as an alternative syntax, specification of arguments using the SHELL: prefix
and space as separator. The previous example then becomes "LINKER:SHELL:-z defs".

Note:
Specifying the SHELL: prefix anywhere other than at the beginning of the LINKER: prefix is not
supported.

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 <#
variable:CMAKE_LINK_SEARCH_END_STATIC> if it is set when a target is created.

See also LINK_SEARCH_START_STATIC <#prop_tgt: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 <#variable:CMAKE_LINK_SEARCH_START_STATIC> if it is set when a
target is created.

See also LINK_SEARCH_END_STATIC <#prop_tgt:LINK_SEARCH_END_STATIC>.

LINK_WHAT_YOU_USE
Added in version 3.7.

This is a boolean option that, when set to TRUE, will automatically run contents of variable
CMAKE_LINK_WHAT_YOU_USE_CHECK <#variable:CMAKE_LINK_WHAT_YOU_USE_CHECK> on the target after it is linked.
In addition, the linker flag specified by variable CMAKE_<LANG>_LINK_WHAT_YOU_USE_FLAG <#
variable:CMAKE_<LANG>_LINK_WHAT_YOU_USE_FLAG> 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.

Note:
For now, it is only supported for ELF platforms and is only applicable to executable and shared or
module library targets. This property will be ignored for any other targets and configurations.

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

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. Details of the linker preferences are considered internal, but some limited
discussion can be found under the internal CMAKE_<LANG>_LINKER_PREFERENCE <#
variable:CMAKE_<LANG>_LINKER_PREFERENCE> variables.

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

LINKER_TYPE
Added in version 3.29.

Specify which linker will be used for the link step. The property value may use generator expressions <#
manual:cmake-generator-expressions(7)>.

Note:
It is assumed that the linker specified is fully compatible with the default one the compiler would
normally invoke. CMake will not do any option translation.

Linker types are case-sensitive and may only contain letters, numbers and underscores. Linker types
defined in all uppercase are reserved for CMake's own built-in types. The pre-defined linker types are:

DEFAULT
This type corresponds to standard linking, essentially equivalent to the LINKER_TYPE target
property not being set at all.

SYSTEM Use the standard linker provided by the platform or toolchain. For example, this implies the
Microsoft linker for all MSVC-compatible compilers. This type is supported for the following
platform-compiler combinations:

• Linux: GNU, Clang, LLVMFlang, NVIDIA, and Swift compilers.

• Apple platforms: AppleClang, Clang, GNU, and Swift compilers.

• Windows: MSVC, GNU, Clang, NVIDIA, and Swift compilers.

LLD Use the LLVM linker. This type is supported for the following platform-compiler combinations:

• Linux: GNU, Clang, LLVMFlang, NVIDIA, and Swift compilers.

• Apple platforms: Clang, AppleClang, and Swift compilers.

• Windows: GNU, Clang with MSVC-like front-end, Clang with GNU-like front-end, MSVC, NVIDIA with
MSVC-like front-end, and Swift.

BFD Use the GNU linker. This type is supported for the following platform-compiler combinations:

• Linux: GNU, Clang, LLVMFlang, and NVIDIA compilers.

• Windows: GNU, Clang with GNU-like front-end.

GOLD Supported on Linux platform with GNU, Clang, LLVMFlang, NVIDIA, and Swift compilers.

MOLD Use the mold linker <https://github.com/rui314/mold>. This type is supported on the following
platform-compiler combinations:

• Linux: GNU, Clang, LLVMFlang, and NVIDIA compilers.

• Apple platforms: Clang and AppleClang compilers (acts as an alias to the sold linker <https://
github.com/bluewhalesystems/sold>).

SOLD Use the sold linker <https://github.com/bluewhalesystems/sold>. This type is only supported on
Apple platforms with Clang and AppleClang compilers.

APPLE_CLASSIC
Use the Apple linker in the classic behavior (i.e. before Xcode 15.0). This type is only
supported on Apple platforms with GNU, Clang, AppleClang, and Swift compilers.

MSVC Use the Microsoft linker. This type is only supported on the Windows platform with MSVC, Clang
with MSVC-like front-end, and Swift compilers.

This property is not supported on Green Hills MULTI <#generator:Green Hills MULTI> generator.

The implementation details for the selected linker will be provided by the
CMAKE_<LANG>_USING_LINKER_<TYPE> <#variable:CMAKE_<LANG>_USING_LINKER_<TYPE>> variable. For example:

add_library(lib1 SHARED ...)
set_property(TARGET lib1 PROPERTY LINKER_TYPE LLD)

This specifies that lib1 should use linker type LLD for the link step. The command line options that
will be passed to the toolchain will be provided by the CMAKE_<LANG>_USING_LINKER_LLD variable.

Note that the linker would typically be set using CMAKE_LINKER_TYPE <#variable:CMAKE_LINKER_TYPE> for the
whole build rather than setting the LINKER_TYPE property on individual targets.

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() <#
command: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() <#command: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() <#command:add_custom_command> recognizes generator expressions <#
manual:cmake-generator-expressions(7)> 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.

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> <#prop_tgt: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 <#prop_tgt:LINKER_LANGUAGE>. Failure to follow this rule
is not diagnosed and leaves the location of the target undefined.

MACHO_COMPATIBILITY_VERSION
Added in version 3.17.

What compatibility version number is this target for Mach-O binaries.

For shared libraries on Mach-O systems (e.g. macOS, iOS) the MACHO_COMPATIBILITY_VERSION property
corresponds to the compatibility version and MACHO_CURRENT_VERSION <#prop_tgt:MACHO_CURRENT_VERSION>
corresponds to the current version. These are both embedded in the shared library binary and can be
checked with the otool -L <binary> command.

It should be noted that the MACHO_CURRENT_VERSION <#prop_tgt:MACHO_CURRENT_VERSION> and
MACHO_COMPATIBILITY_VERSION properties do not affect the file names or version-related symlinks that
CMake generates for the library. The VERSION <#prop_tgt:VERSION> and SOVERSION <#prop_tgt:SOVERSION>
target properties still control the file and symlink names. The install_name is also still controlled by
SOVERSION <#prop_tgt:SOVERSION>.

When MACHO_CURRENT_VERSION <#prop_tgt:MACHO_CURRENT_VERSION> and MACHO_COMPATIBILITY_VERSION are not
given, VERSION <#prop_tgt:VERSION> and SOVERSION <#prop_tgt:SOVERSION> are used for the version details
to be embedded in the binaries respectively. The MACHO_CURRENT_VERSION <#prop_tgt:MACHO_CURRENT_VERSION>
and MACHO_COMPATIBILITY_VERSION properties only need to be given if the project needs to decouple the
file and symlink naming from the version details embedded in the binaries (e.g. to match libtool
conventions).

MACHO_CURRENT_VERSION
Added in version 3.17.

What current version number is this target for Mach-O binaries.

For shared libraries on Mach-O systems (e.g. macOS, iOS) the MACHO_COMPATIBILITY_VERSION <#
prop_tgt:MACHO_COMPATIBILITY_VERSION> property corresponds to the compatibility version and
MACHO_CURRENT_VERSION corresponds to the current version. These are both embedded in the shared library
binary and can be checked with the otool -L <binary> command.

It should be noted that the MACHO_CURRENT_VERSION and MACHO_COMPATIBILITY_VERSION <#
prop_tgt:MACHO_COMPATIBILITY_VERSION> properties do not affect the file names or version-related symlinks
that CMake generates for the library. The VERSION <#prop_tgt:VERSION> and SOVERSION <#
prop_tgt:SOVERSION> target properties still control the file and symlink names. The install_name is also
still controlled by SOVERSION <#prop_tgt:SOVERSION>.

When MACHO_CURRENT_VERSION and MACHO_COMPATIBILITY_VERSION <#prop_tgt:MACHO_COMPATIBILITY_VERSION> are
not given, VERSION <#prop_tgt:VERSION> and SOVERSION <#prop_tgt:SOVERSION> are used for the version
details to be embedded in the binaries respectively. The MACHO_CURRENT_VERSION and
MACHO_COMPATIBILITY_VERSION <#prop_tgt:MACHO_COMPATIBILITY_VERSION> properties only need to be given if
the project needs to decouple the file and symlink naming from the version details embedded in the
binaries (e.g. to match libtool conventions).

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 <#prop_tgt: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 <#variable:CMAKE_MACOSX_BUNDLE> if it is set when a target is created.

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

An executable target with MACOSX_BUNDLE <#prop_tgt: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 <#variable: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_FRAMEWORK_INFO_PLIST
Specify a custom Info.plist template for a macOS and iOS Framework.

A library target with FRAMEWORK <#prop_tgt: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 <#variable: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_NAME
Added in version 3.31.

Sets CFBundleName.

MACOSX_FRAMEWORK_BUNDLE_VERSION
Sets CFBundleVersion.

MACOSX_FRAMEWORK_ICON_FILE
Sets CFBundleIconFile.

MACOSX_FRAMEWORK_IDENTIFIER
Sets CFBundleIdentifier.

MACOSX_FRAMEWORK_SHORT_VERSION_STRING
Sets CFBundleShortVersionString.

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 <#prop_tgt: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 <#
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 <#prop_tgt:INSTALL_RPATH> target property on the target linking to this target.

Policy CMP0042 <#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
Added in version 3.8.

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:add_dependencies> command.

MAP_IMPORTED_CONFIG_<CONFIG>
Map from project configuration to imported target <#imported-targets>'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> <#
prop_tgt: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 <#
prop_tgt: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: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_DEBUG_INFORMATION_FORMAT
Added in version 3.25.

Select debug information format when targeting the MSVC ABI.

The allowed values are:

Embedded
Compile with -Z7 or equivalent flag(s) to produce object files with full symbolic debugging
information.

ProgramDatabase
Compile with -Zi or equivalent flag(s) to produce a program database that contains all the
symbolic debugging information.

EditAndContinue
Compile with -ZI or equivalent flag(s) to produce a program database that supports the Edit and
Continue feature.

The value is ignored on compilers not targeting the MSVC ABI, 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 debug information format flag will be added
explicitly by CMake.

Use generator expressions <#manual:cmake-generator-expressions(7)> to support per-configuration
specification. For example, the code:

add_executable(foo foo.c)
set_property(TARGET foo PROPERTY
MSVC_DEBUG_INFORMATION_FORMAT "$<$<CONFIG:Debug,RelWithDebInfo>:ProgramDatabase>")

selects for the target foo the program database debug information format for the Debug configuration.

This property is initialized from the value of the CMAKE_MSVC_DEBUG_INFORMATION_FORMAT <#
variable:CMAKE_MSVC_DEBUG_INFORMATION_FORMAT> variable, if it is set. If this property is not set, CMake
selects a debug information format using the default value
$<$<CONFIG:Debug,RelWithDebInfo>:ProgramDatabase>, if supported by the compiler, and otherwise
$<$<CONFIG:Debug,RelWithDebInfo>:Embedded>.

Note:
This property has effect only when policy CMP0141 <#policy:CMP0141> is set to NEW prior to the first
project() <#command:project> or enable_language() <#command:enable_language> command that enables a
language using a compiler targeting the MSVC ABI.

MSVC_RUNTIME_LIBRARY
Added in version 3.15.

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 compilers not targeting the MSVC ABI, 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 <#visual-studio-generators> the native
build system may choose to add its own default runtime library selection flag.

Use generator expressions <#manual:cmake-generator-expressions(7)> 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.

The property is initialized from the value of the CMAKE_MSVC_RUNTIME_LIBRARY <#
variable:CMAKE_MSVC_RUNTIME_LIBRARY> variable, if it is set. If the 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 <#policy:CMP0091> is set to NEW prior to the first
project() <#command:project> or enable_language() <#command: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 <#imported-targets> as
system directories.

When the consumed target's SYSTEM <#prop_tgt:SYSTEM> property is set to true, the contents of the
INTERFACE_INCLUDE_DIRECTORIES <#prop_tgt:INTERFACE_INCLUDE_DIRECTORIES> target property are treated as
system includes or, on Apple platforms, when the target is a framework, it will be treated as system. By
default, SYSTEM <#prop_tgt:SYSTEM> is true for imported targets and false for other target types. If the
NO_SYSTEM_FROM_IMPORTED property is set to true on a consuming target, compilation of sources in that
consuming target will not treat the contents of the INTERFACE_INCLUDE_DIRECTORIES <#
prop_tgt:INTERFACE_INCLUDE_DIRECTORIES> of consumed imported targets as system includes, even if that
imported target's SYSTEM <#prop_tgt:SYSTEM> property is false.

Directories listed in the INTERFACE_SYSTEM_INCLUDE_DIRECTORIES <#
prop_tgt:INTERFACE_SYSTEM_INCLUDE_DIRECTORIES> property of consumed targets are not affected by
NO_SYSTEM_FROM_IMPORTED. Those directories will always be treated as system include directories by
consumers.

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

See the EXPORT_NO_SYSTEM <#prop_tgt:EXPORT_NO_SYSTEM> target property to set this behavior on the target
providing the include directories rather than the target consuming them.

OBJC_EXTENSIONS
Added in version 3.16.

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 <#prop_tgt:OBJC_STANDARD>
target property.

If the property is not set, and the project has set the C_EXTENSIONS <#prop_tgt:C_EXTENSIONS>, the value
of C_EXTENSIONS <#prop_tgt:C_EXTENSIONS> is set for OBJC_EXTENSIONS.

See the cmake-compile-features(7) <#manual: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:CMAKE_OBJC_EXTENSIONS>
variable if set when a target is created and otherwise by the value of CMAKE_OBJC_EXTENSIONS_DEFAULT <#
variable:CMAKE_<LANG>_EXTENSIONS_DEFAULT> (see CMP0128 <#policy:CMP0128>).

OBJC_STANDARD
Added in version 3.16.

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 Objective C89/C90

99 Objective C99

11 Objective C11

17 Added in version 3.21.

Objective C17

23 Added in version 3.21.

Objective C23

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 <#prop_tgt:OBJC_STANDARD_REQUIRED> target property.
Additionally, the OBJC_EXTENSIONS <#prop_tgt: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 <#prop_tgt:C_STANDARD>, the value of
C_STANDARD <#prop_tgt:C_STANDARD> is set for OBJC_STANDARD.

See the cmake-compile-features(7) <#manual: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:CMAKE_OBJC_STANDARD>
variable if it is set when a target is created.

OBJC_STANDARD_REQUIRED
Added in version 3.16.

Boolean describing whether the value of OBJC_STANDARD <#prop_tgt:OBJC_STANDARD> is a requirement.

If this property is set to ON, then the value of the OBJC_STANDARD <#prop_tgt:OBJC_STANDARD> target
property is treated as a requirement. If this property is OFF or unset, the OBJC_STANDARD <#
prop_tgt: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 <#
prop_tgt:C_STANDARD_REQUIRED>, the value of C_STANDARD_REQUIRED <#prop_tgt:C_STANDARD_REQUIRED> is set
for OBJC_STANDARD_REQUIRED.

See the cmake-compile-features(7) <#manual: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:CMAKE_OBJC_STANDARD_REQUIRED> variable if it is set when a target is created.

OBJCXX_EXTENSIONS
Added in version 3.16.

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 <#
prop_tgt:OBJCXX_STANDARD> target property.

See the cmake-compile-features(7) <#manual: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 <#prop_tgt:CXX_EXTENSIONS>, the
value of CXX_EXTENSIONS <#prop_tgt:CXX_EXTENSIONS> is set for OBJCXX_EXTENSIONS.

This property is initialized by the value of the CMAKE_OBJCXX_EXTENSIONS <#
variable:CMAKE_OBJCXX_EXTENSIONS> variable if set when a target is created and otherwise by the value of
CMAKE_OBJCXX_EXTENSIONS_DEFAULT <#variable:CMAKE_<LANG>_EXTENSIONS_DEFAULT> (see CMP0128 <#
policy:CMP0128>).

OBJCXX_STANDARD
Added in version 3.16.

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 Objective C++98

11 Objective C++11

14 Objective C++14

17 Objective C++17

20 Objective C++20

23 Added in version 3.20.

Objective C++23

26 Added in version 3.25.

Objective C++26. CMake 3.25 and later recognize 26 as a valid value, no version has support for
any compiler.

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 <#prop_tgt:OBJCXX_STANDARD_REQUIRED> target property.
Additionally, the OBJCXX_EXTENSIONS <#prop_tgt: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 <#prop_tgt:CXX_STANDARD>, the value
of CXX_STANDARD <#prop_tgt:CXX_STANDARD> is set for OBJCXX_STANDARD.

See the cmake-compile-features(7) <#manual: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:CMAKE_OBJCXX_STANDARD>
variable if it is set when a target is created.

OBJCXX_STANDARD_REQUIRED
Added in version 3.16.

Boolean describing whether the value of OBJCXX_STANDARD <#prop_tgt:OBJCXX_STANDARD> is a requirement.

If this property is set to ON, then the value of the OBJCXX_STANDARD <#prop_tgt:OBJCXX_STANDARD> target
property is treated as a requirement. If this property is OFF or unset, the OBJCXX_STANDARD <#
prop_tgt: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 <#
prop_tgt:CXX_STANDARD_REQUIRED>, the value of CXX_STANDARD_REQUIRED <#prop_tgt:CXX_STANDARD_REQUIRED> is
set for OBJCXX_STANDARD_REQUIRED.

See the cmake-compile-features(7) <#manual: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:CMAKE_OBJCXX_STANDARD_REQUIRED> variable if it is set when a target is created.

OPTIMIZE_DEPENDENCIES
Added in version 3.19.

Activates dependency optimization of static and object libraries.

When this property is set to true, some dependencies for a static or object library may be removed at
generation time if they are not necessary to build the library, since static and object libraries don't
actually link against anything.

If a static or object library has dependency optimization enabled, it first discards all dependencies.
Then, it looks through all of the direct and indirect dependencies that it initially had, and adds them
back if they meet any of the following criteria:

• The dependency was added to the library by add_dependencies() <#command:add_dependencies>.

• The dependency was added to the library through a source file in the library generated by a custom
command that uses the dependency.

• The dependency has any PRE_BUILD, PRE_LINK, or POST_BUILD custom commands associated with it.

• The dependency contains any source files that were generated by a custom command.

• The dependency contains any languages which produce side effects that are relevant to the library.
Currently, all languages except C, C++, Objective-C, Objective-C++, assembly, and CUDA are assumed to
produce side effects. However, side effects from one language are assumed not to be relevant to
another (for example, a Fortran library is assumed to not have any side effects that are relevant for a
Swift library.)

As an example, assume you have a static Fortran library which depends on a static C library, which in
turn depends on a static Fortran library. The top-level Fortran library has optimization enabled, but the
middle C library does not. If you build the top Fortran library, the bottom Fortran library will also
build, but not the middle C library, since the C library does not have any side effects that are relevant
for the Fortran library. However, if you build the middle C library, the bottom Fortran library will also
build, even though it does not have any side effects that are relevant to the C library, since the C
library does not have optimization enabled.

This property is initialized by the value of the CMAKE_OPTIMIZE_DEPENDENCIES <#
variable:CMAKE_OPTIMIZE_DEPENDENCIES> variable when the target is created.

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 <#
variable:CMAKE_OSX_ARCHITECTURES> if it is set when a target is created. Use OSX_ARCHITECTURES_<CONFIG>
<#prop_tgt: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).

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

This property is the configuration-specific version of OSX_ARCHITECTURES <#prop_tgt:OSX_ARCHITECTURES>.

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 <#
manual:cmake-generator-expressions(7)>.

PROPERTIES ON TESTS

ATTACHED_FILES
Attach a list of files to a dashboard submission.

Set this property to a list of files that will be encoded and submitted to the dashboard as an addition
to the test result.

ATTACHED_FILES_ON_FAIL
Attach a list of files to a dashboard submission if the test fails.

Same as ATTACHED_FILES <#prop_test:ATTACHED_FILES>, but these files will only be included if the test
does not pass.

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 <#manual:ctest(1)> 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 <#prop_test:FIXTURES_REQUIRED>).

Examples
add_test(NAME baseTest1 ...)
add_test(NAME baseTest2 ...)
add_test(NAME dependsTest12 ...)

set_tests_properties(dependsTest12 PROPERTIES DEPENDS "baseTest1;baseTest2")
# dependsTest12 runs after baseTest1 and baseTest2, even if they fail

DISABLED
Added in version 3.9.

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 <#prop_test: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 <#prop_test: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.

Set to a semicolon-separated list <#cmake-language-lists> list of environment variables and values of the
form MYVAR=value. Those environment variables will be defined while running the test. The environment
changes from this property do not affect other tests.

ENVIRONMENT_MODIFICATION
Added in version 3.22.

Specify environment variables that should be modified for running a test. Note that the operations
performed by this property are performed after the ENVIRONMENT <#prop_test:ENVIRONMENT> property is
already applied.

Set to a semicolon-separated list <#cmake-language-lists> of environment variables and values of the form
MYVAR=OP:VALUE, where MYVAR is the case-sensitive name of an environment variable to be modified.
Entries are considered in the order specified in the property's value. The OP may be one of:

• reset: Reset to the unmodified value, ignoring all modifications to MYVAR prior to this entry. Note
that this will reset the variable to the value set by ENVIRONMENT <#prop_test:ENVIRONMENT>, if it
was set, and otherwise to its state from the rest of the CTest execution.

• set: Replaces the current value of MYVAR with VALUE.

• unset: Unsets the current value of MYVAR.

• string_append: Appends singular VALUE to the current value of MYVAR.

• string_prepend: Prepends singular VALUE to the current value of MYVAR.

• path_list_append: Appends singular VALUE to the current value of MYVAR using the host platform's
path list separator (; on Windows and : elsewhere).

• path_list_prepend: Prepends singular VALUE to the current value of MYVAR using the host platform's
path list separator (; on Windows and : elsewhere).

• cmake_list_append: Appends singular VALUE to the current value of MYVAR using ; as the separator.

• cmake_list_prepend: Prepends singular VALUE to the current value of MYVAR using ; as the separator.

Unrecognized OP values will result in the test failing before it is executed. This is so that future
operations may be added without changing valid behavior of existing tests.

The environment changes from this property do not affect other tests.

FAIL_REGULAR_EXPRESSION
If the test output (stdout or stderr) matches this regular expression the test will fail, regardless of
the process exit code. Tests that exceed the timeout specified by TIMEOUT <#prop_test:TIMEOUT> fail
regardless of FAIL_REGULAR_EXPRESSION. Any non-zero return code or system-level test failures including
segmentation faults, signal abort, or heap errors fail the test even if the regular expression does not
match.

If set, if the output matches one of specified regular expressions, the test will fail. Example:

# test would pass, except for FAIL_REGULAR_EXPRESSION
add_test(NAME mytest COMMAND ${CMAKE_COMMAND} -E echo "Failed")

set_property(TEST mytest PROPERTY
FAIL_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"
)

FAIL_REGULAR_EXPRESSION expects a list of regular expressions.

See also the PASS_REGULAR_EXPRESSION <#prop_test:PASS_REGULAR_EXPRESSION> and SKIP_REGULAR_EXPRESSION <#
prop_test:SKIP_REGULAR_EXPRESSION> test properties.

FIXTURES_CLEANUP
Added in version 3.7.

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 <#prop_test: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 <#prop_test: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 <#prop_test:FIXTURES_REQUIRED> for a more complete discussion of how to use test
fixtures.

FIXTURES_REQUIRED
Added in version 3.7.

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 <#prop_test:FIXTURES_SETUP> property and as
cleanup tasks with the FIXTURES_CLEANUP <#prop_test: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 <#cmdoption-ctest-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 <#cmdoption-ctest-FS>, -FC <#cmdoption-ctest-FC> and -FA <#
cmdoption-ctest-FA> command line options to ctest(1) <#manual:ctest(1)> if desired.

Since setup and cleanup tasks are also tests, they can have an ordering specified by the DEPENDS <#
prop_test: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 <#
prop_test: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, serializing
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 <#prop_test:RESOURCE_LOCK> to combine the two
behaviors. Names used for RESOURCE_LOCK <#prop_test: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
Added in version 3.7.

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 <#prop_test: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 <#prop_test: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
<#prop_test:FIXTURES_REQUIRED> property will be run. Cleanup tests will, however, still be executed.

See FIXTURES_REQUIRED <#prop_test:FIXTURES_REQUIRED> for a more complete discussion of how to use test
fixtures.

GENERATED_RESOURCE_SPEC_FILE
Added in version 3.28.

Path to the dynamically-generated resource spec file <#ctest-resource-dynamically-generated-spec-file>
generated by this test.

LABELS
Specify a list of text labels associated with a test. The labels are reported in both the ctest output
summary and in dashboard submissions. They can also be used to filter the set of tests to be executed
(see the ctest -L <#cmdoption-ctest-L> and ctest -LE <#cmdoption-ctest-LE> options).

See Additional Labels <#additional-labels> for adding labels to a test dynamically during test execution.

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 test output (stdout or stderr) must match this regular expression for the test to pass. The process
exit code is ignored. Tests that exceed the timeout specified by TIMEOUT <#prop_test:TIMEOUT> still fail
regardless of PASS_REGULAR_EXPRESSION. System-level test failures including segmentation faults, signal
abort, or heap errors may fail the test even if PASS_REGULAR_EXPRESSION is matched.

Example:

add_test(NAME mytest COMMAND ${CMAKE_COMMAND} -E echo "Passed this test")

set_property(TEST mytest PROPERTY
PASS_REGULAR_EXPRESSION "pass;Passed"
)

PASS_REGULAR_EXPRESSION expects a list of regular expressions.

To run a test that may have a system-level failure, but still pass if PASS_REGULAR_EXPRESSION matches,
use a CMake command to wrap the executable run. Note that this will prevent automatic handling of the
CROSSCOMPILING_EMULATOR <#prop_tgt:CROSSCOMPILING_EMULATOR> and TEST_LAUNCHER <#prop_tgt:TEST_LAUNCHER>
target property.

add_executable(main main.c)

add_test(NAME sigabrt COMMAND ${CMAKE_COMMAND} -E env $<TARGET_FILE:main>)

set_property(TEST sigabrt PROPERTY PROPERTY_REGULAR_EXPRESSION "pass;Passed")

#include <signal.h>
#include <stdio.h>

int main(void){
fprintf(stdout, "Passed\n");
fflush(stdout); /* ensure the output buffer is seen */
raise(SIGABRT);
return 0;
}

See also the FAIL_REGULAR_EXPRESSION <#prop_test:FAIL_REGULAR_EXPRESSION> and SKIP_REGULAR_EXPRESSION <#
prop_test:SKIP_REGULAR_EXPRESSION> test properties.

PROCESSOR_AFFINITY
Added in version 3.12.

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 <#prop_test: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() <#command: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) <#manual: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 <#prop_test:PROCESSOR_AFFINITY> test property.

REQUIRED_FILES
List of files required to run the test. The filenames are relative to the test WORKING_DIRECTORY <#
prop_test:WORKING_DIRECTORY> unless an absolute path is specified.

If set to a list of files, the test will not be run unless all of the files exist.

Examples
Suppose that test.txt is created by test baseTest and none.txt does not exist:

add_test(NAME baseTest ...) # Assumed to create test.txt
add_test(NAME fileTest ...)

# The following ensures that if baseTest is successful, test.txt will
# have been created before fileTest is run
set_tests_properties(fileTest PROPERTIES
DEPENDS baseTest
REQUIRED_FILES test.txt
)

add_test(NAME notRunTest ...)

# The following makes notRunTest depend on two files. Nothing creates
# the none.txt file, so notRunTest will fail with status "Not Run".
set_tests_properties(notRunTest PROPERTIES
REQUIRED_FILES "test.txt;none.txt"
)

The above example demonstrates how REQUIRED_FILES works, but it is not the most robust way to implement
test ordering with failure detection. For that, test fixtures are a better alternative (see
FIXTURES_REQUIRED <#prop_test:FIXTURES_REQUIRED>).

RESOURCE_GROUPS
Added in version 3.16.

Specify resources required by a test, grouped in a way that is meaningful to the test. See resource
allocation <#ctest-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 <#cmake-language-lists> 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 <#ctest-resource-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 <#ctest-resource-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 <#prop_test:RESOURCE_LOCK> properties serve similar purposes,
but they are distinct and orthogonal. Resources specified by RESOURCE_GROUPS do not affect RESOURCE_LOCK
<#prop_test:RESOURCE_LOCK>, and vice versa. Whereas RESOURCE_LOCK <#prop_test: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 <#prop_test:FIXTURES_REQUIRED> if the resource requires any setup or cleanup
steps.

Both the RESOURCE_GROUPS <#prop_test:RESOURCE_GROUPS> and RESOURCE_LOCK properties serve similar
purposes, but they are distinct and orthogonal. Resources specified by RESOURCE_GROUPS <#
prop_test: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 <#
prop_test: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
Added in version 3.16.

If the test output (stderr or stdout) matches this regular expression the test will be marked as skipped,
regardless of the process exit code. Tests that exceed the timeout specified by TIMEOUT <#
prop_test:TIMEOUT> still fail regardless of SKIP_REGULAR_EXPRESSION. System-level test failures including
segmentation faults, signal abort, or heap errors may fail the test even if the regular expression
matches.

Example:

add_test(NAME mytest COMMAND ${CMAKE_COMMAND} -E echo "Skipped this test")

set_property(TEST mytest PROPERTY
SKIP_REGULAR_EXPRESSION "[^a-z]Skip" "SKIP" "Skipped"
)

SKIP_REGULAR_EXPRESSION expects a list of regular expressions.

To run a test that may have a system-level failure, but still skip if SKIP_REGULAR_EXPRESSION matches,
use a CMake command to wrap the executable run. Note that this will prevent automatic handling of the
CROSSCOMPILING_EMULATOR <#prop_tgt:CROSSCOMPILING_EMULATOR> and TEST_LAUNCHER <#prop_tgt:TEST_LAUNCHER>
target property.

add_executable(main main.c)

add_test(NAME sigabrt COMMAND ${CMAKE_COMMAND} -E env $<TARGET_FILE:main>)

set_property(TEST sigabrt PROPERTY SKIP_REGULAR_EXPRESSION "SIGABRT;[aA]bort")

#include <signal.h>

int main(void){ raise(SIGABRT); return 0; }

See also the SKIP_RETURN_CODE <#prop_test:SKIP_RETURN_CODE>, PASS_REGULAR_EXPRESSION <#
prop_test:PASS_REGULAR_EXPRESSION>, and FAIL_REGULAR_EXPRESSION <#prop_test:FAIL_REGULAR_EXPRESSION> test
properties.

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.

Tests that exceed the timeout specified by TIMEOUT <#prop_test:TIMEOUT> still fail regardless of
SKIP_RETURN_CODE. System-level test failures including segmentation faults, signal abort, or heap errors
may fail the test even if the return code matches.

# cmake (1) defines this to return code 1
add_test(NAME r1 COMMAND ${CMAKE_COMMAND} -E false)

set_tests_properties(r1 PROPERTIES SKIP_RETURN_CODE 1)

To run a test that may have a system-level failure, but still skip if SKIP_RETURN_CODE matches, use a
CMake command to wrap the executable run. Note that this will prevent automatic handling of the
CROSSCOMPILING_EMULATOR <#prop_tgt:CROSSCOMPILING_EMULATOR> and TEST_LAUNCHER <#prop_tgt:TEST_LAUNCHER>
target property.

add_executable(main main.c)

# cmake -E env <command> returns 1 if the command fails in any way
add_test(NAME sigabrt COMMAND ${CMAKE_COMMAND} -E env $<TARGET_FILE:main>)

set_property(TEST sigabrt PROPERTY SKIP_RETURN_CODE 1)

#include <signal.h>

int main(void){ raise(SIGABRT); return 0; }

To handle multiple types of cases that may need to be skipped, consider the SKIP_REGULAR_EXPRESSION <#
prop_test: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 <#variable:CTEST_TEST_TIMEOUT>.

An explicit 0 value means the test has no timeout, except as necessary to honor ctest --stop-time <#
cmdoption-ctest-stop-time>.

See also TIMEOUT_AFTER_MATCH <#prop_test:TIMEOUT_AFTER_MATCH> and TIMEOUT_SIGNAL_NAME <#
prop_test:TIMEOUT_SIGNAL_NAME>.

TIMEOUT_AFTER_MATCH
Added in version 3.6.

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
<#prop_test:TIMEOUT> property or the CTEST_TEST_TIMEOUT <#variable: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 <#prop_test: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 <#
prop_test: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.

See also TIMEOUT_SIGNAL_NAME <#prop_test:TIMEOUT_SIGNAL_NAME>.

TIMEOUT_SIGNAL_GRACE_PERIOD
Added in version 3.27.

If the TIMEOUT_SIGNAL_NAME <#prop_test:TIMEOUT_SIGNAL_NAME> test property is set, this property specifies
the number of seconds to wait for a test process to terminate after sending the custom signal.
Otherwise, this property has no meaning.

The grace period may be any real value greater than 0.0, but not greater than 60.0. If this property is
not set, the default is 1.0 second.

This is available only on platforms supporting POSIX signals. It is not available on Windows.

TIMEOUT_SIGNAL_NAME
Added in version 3.27.

Specify a custom signal to send to a test process when its timeout is reached. This is available only on
platforms supporting POSIX signals. It is not available on Windows.

The name must be one of the following:

SIGINT Interrupt.

SIGQUIT
Quit.

SIGTERM
Terminate.

SIGUSR1
User defined signal 1.

SIGUSR2
User defined signal 2.

The custom signal is sent to the test process to give it a chance to exit gracefully during a grace
period:

• If the test process created any children, it is responsible for terminating them too.

• The grace period length is determined by the TIMEOUT_SIGNAL_GRACE_PERIOD <#
prop_test:TIMEOUT_SIGNAL_GRACE_PERIOD> test property.

• If the test process does not terminate before the grace period ends, ctest(1) <#manual:ctest(1)> will
force termination of its entire process tree via SIGSTOP and SIGKILL.

See also CTEST_TEST_TIMEOUT <#variable:CTEST_TEST_TIMEOUT>, TIMEOUT <#prop_test:TIMEOUT>, and
TIMEOUT_AFTER_MATCH <#prop_test:TIMEOUT_AFTER_MATCH>.

WILL_FAIL
If true, inverts the pass / fail test criteria. Tests for which WILL_FAIL is true fail with return code 0
and pass with non-zero return code. Tests that exceed the timeout specified by TIMEOUT <#
prop_test:TIMEOUT> still fail regardless of WILL_FAIL. System-level test failures including segmentation
faults, signal abort, or heap errors may fail the test even if WILL_FAIL is true.

Example of a test that would ordinarily pass, but fails because WILL_FAIL is true:

add_test(NAME failed COMMAND ${CMAKE_COMMAND} -E true)
set_property(TEST failed PROPERTY WILL_FAIL true)

To run a test that may have a system-level failure, but still pass if WILL_FAIL is set, use a CMake
command to wrap the executable run. Note that this will prevent automatic handling of the
CROSSCOMPILING_EMULATOR <#prop_tgt:CROSSCOMPILING_EMULATOR> and TEST_LAUNCHER <#prop_tgt:TEST_LAUNCHER>
target property.

add_executable(main main.c)

add_test(NAME sigabrt COMMAND ${CMAKE_COMMAND} -E env $<TARGET_FILE:main>)

set_property(TEST sigabrt PROPERTY WILL_FAIL TRUE)

#include <signal.h>

int main(void){ raise(SIGABRT); return 0; }

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 <#
variable:CMAKE_CURRENT_BINARY_DIR> for where add_test() <#command: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.

AUTORCC_OPTIONS
Additional options for rcc when using AUTORCC <#prop_tgt:AUTORCC>

By default it is empty.

The options set on the .qrc source file may override AUTORCC_OPTIONS <#prop_tgt:AUTORCC_OPTIONS> set on
the target.

EXAMPLE
# ...
set_property(SOURCE resources.qrc PROPERTY AUTORCC_OPTIONS "--compress;9")
# ...

AUTOUIC_OPTIONS
Additional options for uic when using AUTOUIC <#prop_tgt:AUTOUIC>

By default it is empty.

The options set on the .ui source file may override AUTOUIC_OPTIONS <#prop_tgt:AUTOUIC_OPTIONS> set on
the target.

EXAMPLE
# ...
set_property(SOURCE widget.ui PROPERTY AUTOUIC_OPTIONS "--no-protection")
# ...

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.

Added in version 3.26: Any leading -D on an item will be removed.

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) <#
manual:cmake-generator-expressions(7)> with the syntax $<...>. See the cmake-generator-expressions(7) <#
manual:cmake-generator-expressions(7)> manual for available expressions. However, Xcode <#
generator: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 that will be added
to the list of compile flags when this source file builds. The flags will be added after target-wide
flags.

Use COMPILE_DEFINITIONS <#prop_sf: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:cmake-generator-expressions(7)> manual for available expressions.
However, Xcode <#generator: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 <#prop_sf:COMPILE_OPTIONS> property.

COMPILE_OPTIONS
Added in version 3.11.

List of additional options to pass to the compiler.

This property holds a semicolon-separated list <#cmake-language-lists> of options and will be added to
the list of compile flags when this source file builds. The options will be added after target-wide
options.

Contents of COMPILE_OPTIONS may use "generator expressions" with the syntax $<...>. See the
cmake-generator-expressions(7) <#manual:cmake-generator-expressions(7)> manual for available expressions.
However, Xcode <#generator:Xcode> does not support per-config per-source settings, so expressions that
depend on the build configuration are not allowed with that generator.

Usage example:

set_source_files_properties(foo.cpp PROPERTIES COMPILE_OPTIONS "-Wno-unused-parameter;-Wno-missing-field-initializer")

Related properties:

• Prefer this property over COMPILE_FLAGS <#prop_sf:COMPILE_FLAGS>.

• Use COMPILE_DEFINITIONS <#prop_sf:COMPILE_DEFINITIONS> to pass additional preprocessor definitions.

• Use INCLUDE_DIRECTORIES <#prop_sf:INCLUDE_DIRECTORIES> to pass additional include directories.

Related commands:

• add_compile_options() <#command:add_compile_options> for directory-wide settings

• target_compile_options() <#command:target_compile_options> for target-specific settings

CXX_SCAN_FOR_MODULES
Added in version 3.28.

CXX_SCAN_FOR_MODULES is a boolean specifying whether CMake will scan the source for C++ module
dependencies. See also the CXX_SCAN_FOR_MODULES <#prop_tgt:CXX_SCAN_FOR_MODULES> for target-wide
settings.

When this property is set ON, CMake will scan the source at build time and add module dependency
information to the compile line as necessary. When this property is set OFF, CMake will not scan the
source at build time. When this property is unset, the CXX_SCAN_FOR_MODULES <#
prop_tgt:CXX_SCAN_FOR_MODULES> property is consulted.

Note that scanning is only performed if C++20 or higher is enabled for the target and the source uses the
CXX language. Scanning for modules in sources belonging to file sets of type CXX_MODULES is always
performed.

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
<#prop_tgt:Fortran_FORMAT> property if all source files in a target share the same format.

Note:
For some compilers, NAG, PGI and Solaris Studio, setting this to OFF will have no effect.

Fortran_PREPROCESS
Added in version 3.18.

Control whether the Fortran source file should be unconditionally preprocessed.

Consider using the target-wide Fortran_PREPROCESS <#prop_tgt:Fortran_PREPROCESS> property if all source
files in a target need to be preprocessed.

GENERATED
Is this source file generated as part of the build or CMake process.

Changed in version 3.20: Turning on the GENERATED source file property in one directory allows the
associated source file to be used across directories without the need to manually setting that property
for other directory scopes, too. Additionally, it may now be set only to boolean values, and may not be
turned off once turned on. See policy CMP0118 <#policy:CMP0118>.

Changed in version 3.30: Whether or not a source file is generated is an all-or-nothing global property
of the source. Consequently, the GENERATED source file property is now visible in all directories. See
policy CMP0163 <#policy:CMP0163>.

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.

Any file that is

• created by the execution of commands such as add_custom_command() <#command:add_custom_command> which
run during the build

• listed as one of the BYPRODUCTS of an add_custom_command() <#command:add_custom_command> or
add_custom_target() <#command:add_custom_target> command, or

• created by a CMake AUTOGEN operation such as AUTOMOC <#prop_tgt:AUTOMOC>, AUTORCC <#prop_tgt:AUTORCC>,
or AUTOUIC <#prop_tgt:AUTOUIC>

will be marked with the GENERATED property.

When a generated file created as the OUTPUT of an add_custom_command() <#command: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.

The Makefile Generators <#makefile-generators> will remove GENERATED files during make clean.

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 <#prop_tgt:AUTOMOC>, AUTORCC <#prop_tgt:AUTORCC> or AUTOUIC
<#prop_tgt:AUTOUIC> functionality, the AUTOGEN_SOURCE_GROUP <#prop_gbl:AUTOGEN_SOURCE_GROUP>,
AUTOMOC_SOURCE_GROUP <#prop_gbl:AUTOMOC_SOURCE_GROUP>, AUTORCC_SOURCE_GROUP <#
prop_gbl:AUTORCC_SOURCE_GROUP> and AUTOUIC_SOURCE_GROUP <#prop_gbl:AUTOUIC_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() <#command:add_library> or add_executable() <#
command: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() <#command:add_library> or add_executable() <#command:add_executable>
while passing both the pre-processed sources and the original sources, or by using target_sources() <#
command: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
Added in version 3.11.

List of preprocessor include file search directories.

This property holds a semicolon-separated list <#cmake-language-lists> 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: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:cmake-generator-expressions(7)> manual for available expressions.
However, Xcode <#generator: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
Specify the programming language in which a source file is written.

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, HIP, ISPC, and ASM. Setting this property for a file means this file will be compiled,
unless HEADER_FILE_ONLY <#prop_sf:HEADER_FILE_ONLY> is set.

Changed in version 3.20: Setting this property causes the source file to be compiled as the specified
language, using explicit flags if possible. Previously it only caused the specified language's compiler
to be used. See policy CMP0119 <#policy:CMP0119>.

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 <#prop_tgt:MACOSX_BUNDLE>), Core
Foundation Bundle (BUNDLE <#prop_tgt:BUNDLE>), or Framework Bundle (FRAMEWORK <#prop_tgt:FRAMEWORK>). It
is applicable for macOS and iOS.

Executable targets with the MACOSX_BUNDLE <#prop_tgt:MACOSX_BUNDLE> property set are built as macOS or
iOS application bundles on Apple platforms. Shared library targets with the FRAMEWORK <#
prop_tgt:FRAMEWORK> property set are built as macOS or iOS frameworks on Apple platforms. Module library
targets with the BUNDLE <#prop_tgt: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 <#prop_tgt:PUBLIC_HEADER>, PRIVATE_HEADER <#
prop_tgt:PRIVATE_HEADER>, and RESOURCE <#prop_tgt: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 <#prop_tgt: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 <#cmake-language-lists> of full-paths to files on which any object
files compiled from this source file depend. On Makefile Generators <#makefile-generators> and the Ninja
<#generator:Ninja> generator an object file will be recompiled if any of the named files is newer than
it. Visual Studio Generators <#visual-studio-generators> and the Xcode <#generator: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:add_dependencies> command (if one does not already exist due to linking
relationships).

OBJECT_OUTPUTS
Additional outputs for a Ninja <#generator:Ninja> or Makefile Generators <#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 <#generator:Ninja> and Makefile
Generators <#makefile-generators> and will be ignored on other generators.

This property supports generator expressions <#manual:cmake-generator-expressions(7)>.

SKIP_AUTOGEN
Added in version 3.8.

Exclude the source file from AUTOMOC <#prop_tgt:AUTOMOC>, AUTOUIC <#prop_tgt:AUTOUIC> and AUTORCC <#
prop_tgt:AUTORCC> processing (for Qt projects).

For finer exclusion control see SKIP_AUTOMOC <#prop_sf:SKIP_AUTOMOC>, SKIP_AUTOUIC <#
prop_sf:SKIP_AUTOUIC> and SKIP_AUTORCC <#prop_sf:SKIP_AUTORCC>.

EXAMPLE
# ...
set_property(SOURCE file.h PROPERTY SKIP_AUTOGEN ON)
# ...

SKIP_AUTOMOC
Added in version 3.8.

Exclude the source file from AUTOMOC <#prop_tgt:AUTOMOC> processing (for Qt projects).

For broader exclusion control see SKIP_AUTOGEN <#prop_sf:SKIP_AUTOGEN>.

EXAMPLE
# ...
set_property(SOURCE file.h PROPERTY SKIP_AUTOMOC ON)
# ...

SKIP_AUTORCC
Added in version 3.8.

Exclude the source file from AUTORCC <#prop_tgt:AUTORCC> processing (for Qt projects).

For broader exclusion control see SKIP_AUTOGEN <#prop_sf:SKIP_AUTOGEN>.

EXAMPLE
# ...
set_property(SOURCE file.qrc PROPERTY SKIP_AUTORCC ON)
# ...

SKIP_AUTOUIC
Added in version 3.8.

Exclude the source file from AUTOUIC <#prop_tgt: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 <#prop_sf: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_LINTING
Added in version 3.27.

This property allows you to exclude a specific source file from the linting process. The linting process
involves running tools such as <LANG>_CPPLINT <#prop_tgt:<LANG>_CPPLINT>, <LANG>_CLANG_TIDY <#
prop_tgt:<LANG>_CLANG_TIDY>, <LANG>_CPPCHECK <#prop_tgt:<LANG>_CPPCHECK>, and <LANG>_INCLUDE_WHAT_YOU_USE
<#prop_tgt:<LANG>_INCLUDE_WHAT_YOU_USE> on the source files, as well as compiling header files as part of
VERIFY_INTERFACE_HEADER_SETS <#prop_tgt:VERIFY_INTERFACE_HEADER_SETS>. By setting SKIP_LINTING on a
source file, the mentioned linting tools will not be executed for that particular file.

Example
Consider a C++ project that includes multiple source files, such as main.cpp, things.cpp, and
generatedBindings.cpp. In this example, you want to exclude the generatedBindings.cpp file from the
linting process. To achieve this, you can utilize the SKIP_LINTING property with the
set_source_files_properties() <#command:set_source_files_properties> command as shown below:

add_executable(MyApp main.cpp things.cpp generatedBindings.cpp)

set_source_files_properties(generatedBindings.cpp PROPERTIES
SKIP_LINTING ON
)

In the provided code snippet, the SKIP_LINTING property is set to true for the generatedBindings.cpp
source file. As a result, when the linting tools specified by <LANG>_CPPLINT <#prop_tgt:<LANG>_CPPLINT>,
<LANG>_CLANG_TIDY <#prop_tgt:<LANG>_CLANG_TIDY>, <LANG>_CPPCHECK <#prop_tgt:<LANG>_CPPCHECK>, or
<LANG>_INCLUDE_WHAT_YOU_USE <#prop_tgt:<LANG>_INCLUDE_WHAT_YOU_USE> are executed, they will skip
analyzing the generatedBindings.cpp file.

By using the SKIP_LINTING property, you can selectively exclude specific source files from the linting
process. This allows you to focus the linting tools on the relevant parts of your project, enhancing the
efficiency and effectiveness of the linting workflow.

SKIP_PRECOMPILE_HEADERS
Added in version 3.16.

Is this source file skipped by PRECOMPILE_HEADERS <#prop_tgt:PRECOMPILE_HEADERS> feature.

This property helps with build problems that one would run into when using the PRECOMPILE_HEADERS <#
prop_tgt: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
Added in version 3.16.

Setting this property to true ensures the source file will be skipped by unity builds when its associated
target has its UNITY_BUILD <#prop_tgt: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.

Note that sources which are scanned for C++ modules (see cmake-cxxmodules(7) <#
manual:cmake-cxxmodules(7)>) are not eligible for unity build inclusion and will automatically be
excluded.

Swift_DEPENDENCIES_FILE
Added in version 3.15.

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
Added in version 3.15.

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.

UNITY_GROUP
Added in version 3.18.

This property controls which bucket the source will be part of when the UNITY_BUILD_MODE <#
prop_tgt:UNITY_BUILD_MODE> is set to GROUP.

VS_COPY_TO_OUT_DIR
Added in version 3.8.

Sets the <CopyToOutputDirectory> tag for a source file in a Visual Studio project file. Valid values are
Never, Always and PreserveNewest.

VS_CSHARP_<tagname>
Added in version 3.8.

Visual Studio and CSharp source-file-specific configuration.

Tell the Visual Studio generators <#manual:cmake-generators(7)> 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_properties(<filename>
PROPERTIES
VS_CSHARP_DependentUpon <other file>
VS_CSHARP_SubType "Form")

VS_DEPLOYMENT_CONTENT
Added in version 3.1.

Mark a source file as content for deployment with a Windows Phone or Windows Store application when built
with a Visual Studio generators <#manual:cmake-generators(7)>. The value must evaluate to either 1 or 0
and may use generator expressions <#manual:cmake-generator-expressions(7)> 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
Added in version 3.1.

Specifies the deployment location for a content source file with a Windows Phone or Windows Store
application when built with a Visual Studio generators <#manual:cmake-generators(7)>. This property is
only applicable when using VS_DEPLOYMENT_CONTENT <#prop_sf:VS_DEPLOYMENT_CONTENT>. The value represent
the path relative to the app package and applies to all configurations.

VS_INCLUDE_IN_VSIX
Added in version 3.8.

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
Added in version 3.8.

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_SETTINGS
Added in version 3.18.

Set any item metadata on a file.

Added in version 3.22: This property is honored for all source file types. Previously it worked only for
non-built files.

Takes a list of Key=Value pairs. Tells the Visual Studio generator to set Key to Value as item metadata
on the file.

For example:

set_property(SOURCE file.hlsl PROPERTY VS_SETTINGS "Key=Value" "Key2=Value2")

will set Key to Value and Key2 to Value2 on the file.hlsl item as metadata.

Generator expressions <#manual:cmake-generator-expressions(7)> are supported.

VS_SHADER_DISABLE_OPTIMIZATIONS
Added in version 3.11.

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
Added in version 3.11.

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
Added in version 3.1.

Specifies the name of the entry point for the shader of a .hlsl source file.

VS_SHADER_FLAGS
Added in version 3.2.

Set additional Visual Studio shader flags of a .hlsl source file.

VS_SHADER_MODEL
Added in version 3.1.

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
Added in version 3.12.

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
Added in version 3.10.

Set filename for output header file containing object code of a .hlsl source file.

VS_SHADER_TYPE
Added in version 3.1.

Set the Visual Studio shader type of a .hlsl source file.

VS_SHADER_VARIABLE_NAME
Added in version 3.10.

Set name of variable in header file containing object code of a .hlsl source file.

VS_TOOL_OVERRIDE
Added in version 3.7.

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
Added in version 3.3.

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
Added in version 3.1.

Set the Xcode <#generator: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 <#prop_sf:XCODE_LAST_KNOWN_FILE_TYPE>.

XCODE_FILE_ATTRIBUTES
Added in version 3.7.

Add values to the Xcode <#generator: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
Added in version 3.1.

Set the Xcode <#generator: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 <#prop_sf: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: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() <#command:set>,
option() <#command:option>, find_library() <#command: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
       Added in version 3.3.

       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 <#cpack_gen:CPack WIX Generator>.

   CPACK_NEVER_OVERWRITE
       Added in version 3.1.

       Request that this file not be overwritten on install or reinstall.

       The property is currently only supported by the CPack WIX Generator <#cpack_gen:CPack WIX Generator>.

   CPACK_PERMANENT
       Added in version 3.1.

       Request that this file not be removed on uninstall.

       The property is currently only supported by the CPack WIX Generator <#cpack_gen:CPack WIX Generator>.

   CPACK_START_MENU_SHORTCUTS
       Added in version 3.3.

       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_gen:CPack WIX Generator>.

   CPACK_STARTUP_SHORTCUTS
       Added in version 3.3.

       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_gen:CPack WIX Generator>.

   CPACK_WIX_ACL
       Added in version 3.1.

       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:

          https://wixtoolset.org/documentation/manual/v3/xsd/wix/permission.html

       The property is currently only supported by the CPack WIX Generator <#cpack_gen:CPack WIX Generator>.

DEPRECATED PROPERTIES ON DIRECTORIES

   ADDITIONAL_MAKE_CLEAN_FILES
       Deprecated since version 3.15: Use ADDITIONAL_CLEAN_FILES <#prop_dir:ADDITIONAL_CLEAN_FILES> instead.

       Additional files to remove during the clean stage.

       A ;-list <#cmake-language-lists> of files that will be removed as a part of the make clean target.

       Arguments      to      ADDITIONAL_MAKE_CLEAN_FILES      may      use     generator     expressions     <#
       manual:cmake-generator-expressions(7)>.

       This property only works for the Makefile generators.  It is ignored on other generators.

   COMPILE_DEFINITIONS_<CONFIG>
       Ignored.  See CMake Policy CMP0043 <#policy:CMP0043>.

       Per-configuration preprocessor definitions in a directory.

       This is the configuration-specific version of COMPILE_DEFINITIONS  <#prop_dir: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:cmake-generator-expressions(7)> manual for available expressions.
       See  the  cmake-buildsystem(7)  <#manual:cmake-buildsystem(7)>  manual  for  more on defining buildsystem
       properties.

       Generator expressions should be preferred instead of setting this property.

   INTERPROCEDURAL_OPTIMIZATION
       This directory property does not exist anymore.

       See the target property INTERPROCEDURAL_OPTIMIZATION <#prop_tgt:INTERPROCEDURAL_OPTIMIZATION> instead.

   INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
       This directory property does not exist anymore.

       See         the         target         property         INTERPROCEDURAL_OPTIMIZATION_<CONFIG>          <#
       prop_tgt:INTERPROCEDURAL_OPTIMIZATION_<CONFIG>> instead.

   TEST_INCLUDE_FILE
       Deprecated.  Use TEST_INCLUDE_FILES <#prop_dir: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 <#policy:CMP0043>.

       Per-configuration preprocessor definitions on a target.

       This is the configuration-specific version of COMPILE_DEFINITIONS  <#prop_tgt: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:cmake-generator-expressions(7)> manual for available expressions.
       See  the  cmake-buildsystem(7)  <#manual:cmake-buildsystem(7)>  manual  for  more on defining buildsystem
       properties.

       Generator expressions should be preferred instead of setting this property.

   IMPORTED_NO_SYSTEM
       Added in version 3.23.

       Deprecated since version 3.25: IMPORTED_NO_SYSTEM is deprecated. Please use  the  following  alternatives
       instead:

       • Set  SYSTEM  <#prop_tgt:SYSTEM> to false if you don't want a target's include directories to be treated
         as system directories when compiling consumers.

       • Set EXPORT_NO_SYSTEM <#prop_tgt:EXPORT_NO_SYSTEM> to true if you don't want the include directories  of
         the  imported  target generated by install(EXPORT) <#export> and export() <#command:export> commands to
         be treated as system directories when compiling consumers.

       Setting IMPORTED_NO_SYSTEM to true on an imported target <#imported-targets> specifies that it is  not  a
       system target.  This has the following effects:

       • Entries  of  INTERFACE_INCLUDE_DIRECTORIES <#prop_tgt:INTERFACE_INCLUDE_DIRECTORIES> are not treated as
         system include directories when compiling consumers (regardless of the value of the  consumed  target's
         SYSTEM    <#prop_tgt:SYSTEM>    property),    as    they    would   be   by   default.     Entries   of
         INTERFACE_SYSTEM_INCLUDE_DIRECTORIES <#prop_tgt:INTERFACE_SYSTEM_INCLUDE_DIRECTORIES> are not affected,
         and will always be treated as system include directories.

       • On Apple platforms, when the target is a framework, it will not be treated as system.

       This property can also be enabled on a non-imported target.  Doing so does not affect the  build  system,
       but  does  tell the install(EXPORT) <#export> and export() <#command:export> commands to enable it on the
       imported targets they generate.

       See the NO_SYSTEM_FROM_IMPORTED <#prop_tgt:NO_SYSTEM_FROM_IMPORTED> target property to set this  behavior
       on the target consuming the include directories rather than the one providing them.

   IOS_INSTALL_COMBINED
       Added in version 3.5.

       Deprecated  since  version  3.28: IOS_INSTALL_COMBINED was designed to make universal binaries containing
       iOS/arm* device code paired  with  iOS  Simulator/x86_64  code  (or  similar  for  other  Apple  embedded
       platforms).  Universal  binaries  can  only differentiate code based on CPU type, so this only made sense
       before the days of arm64 macOS machines (i.e. iOS Simulator/arm64). Apple  now  recommends  xcframeworks,
       which contain multiple binaries for different platforms, for this use case.

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

       When  this  property  is 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 other SDK and combined into one library.

       Note:
          If a selected architecture is available for both device SDK and simulator SDK it will be built for the
          SDK selected by CMAKE_OSX_SYSROOT <#variable:CMAKE_OSX_SYSROOT> and removed from the other SDK.

       This feature requires at least Xcode version 6.

   POST_INSTALL_SCRIPT
       Deprecated install support.

       The  PRE_INSTALL_SCRIPT <#prop_tgt: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:install> command
       instead.

   PRE_INSTALL_SCRIPT
       Deprecated install support.

       The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT <#prop_tgt: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:install> command
       instead.

   VS_WINRT_EXTENSIONS
       Deprecated.   Use  VS_WINRT_COMPONENT  <#prop_tgt:VS_WINRT_COMPONENT>  instead.   This  property  was  an
       experimental partial implementation of that one.

DEPRECATED PROPERTIES ON SOURCE FILES

   COMPILE_DEFINITIONS_<CONFIG>
       Ignored.  See CMake Policy CMP0043 <#policy:CMP0043>.

       Per-configuration preprocessor definitions on a source file.

       This  is the configuration-specific version of COMPILE_DEFINITIONS <#prop_tgt:COMPILE_DEFINITIONS>.  Note
       that Xcode <#generator:Xcode> does not support per-configuration source file flags so this property  will
       be ignored by the Xcode <#generator:Xcode> generator.
