| FeatureSummary |
| -------------- |
| |
| Functions for generating a summary of enabled/disabled features. |
| |
| These functions can be used to generate a summary of enabled and disabled |
| packages and/or feature for a build tree such as:: |
| |
| -- The following OPTIONAL packages have been found: |
| LibXml2 (required version >= 2.4), XML processing lib, <http://xmlsoft.org> |
| * Enables HTML-import in MyWordProcessor |
| * Enables odt-export in MyWordProcessor |
| PNG, A PNG image library., <http://www.libpng.org/pub/png/> |
| * Enables saving screenshots |
| -- The following OPTIONAL packages have not been found: |
| Lua51, The Lua scripting language., <https://www.lua.org> |
| * Enables macros in MyWordProcessor |
| Foo, Foo provides cool stuff. |

| Global Properties |
| ^^^^^^^^^^^^^^^^^ |
| |
| .. variable:: FeatureSummary_PKG_TYPES |
| |
| The global property :variable:`FeatureSummary_PKG_TYPES` defines the type of |
| packages used by `FeatureSummary`. |
| |
| The order in this list is important, the first package type in the list is the |
| least important, the last is the most important. the of a package can only be |
| changed to higher types. |
| |
| The default package types are , ``RUNTIME``, ``OPTIONAL``, ``RECOMMENDED`` and |
| ``REQUIRED``, and their importance is |
| ``RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED``. |
| |
| |
| .. variable:: FeatureSummary_REQUIRED_PKG_TYPES |
| |
| The global property :variable:`FeatureSummary_REQUIRED_PKG_TYPES` defines which |
| package types are required. |
| |
| If one or more package in this categories has not been found, CMake will abort |
| when calling :command:`feature_summary` with the |
| 'FATAL_ON_MISSING_REQUIRED_PACKAGES' option enabled. |
| |
| The default value for this global property is ``REQUIRED``. |
| |
| |
| .. variable:: FeatureSummary_DEFAULT_PKG_TYPE |
| |
| The global property :variable:`FeatureSummary_DEFAULT_PKG_TYPE` defines which |
| package type is the default one. |
| When calling :command:`feature_summary`, if the user did not set the package type |
| explicitly, the package will be assigned to this category. |
| |
| This value must be one of the types defined in the |
| :variable:`FeatureSummary_PKG_TYPES` global property unless the package type |
| is set for all the packages. |
| |
| The default value for this global property is ``OPTIONAL``. |
| |
| |
| .. variable:: FeatureSummary_<TYPE>_DESCRIPTION |
| |
| .. versionadded:: 3.9 |
| |
| The global property :variable:`FeatureSummary_<TYPE>_DESCRIPTION` can be defined |
| for each type to replace the type name with the specified string whenever the |
| package type is used in an output string. |
| |
| If not set, the string "``<TYPE>`` packages" is used. |

| WHAT (ALL |
| | PACKAGES_FOUND | PACKAGES_NOT_FOUND |
| | <TYPE>_PACKAGES_FOUND | <TYPE>_PACKAGES_NOT_FOUND |
| | ENABLED_FEATURES | DISABLED_FEATURES) |
| ) |
| |
| The ``feature_summary()`` macro can be used to print information about |
| enabled or disabled packages or features of a project. By default, |
| only the names of the features/packages will be printed and their |
| required version when one was specified. Use ``set_package_properties()`` |
| to add more useful information, like e.g. a download URL for the |
| respective package or their purpose in the project. |
| |
| The ``WHAT`` option is the only mandatory option. Here you specify what |
| information will be printed: |
| |
| ``ALL`` |
| print everything |
| ``ENABLED_FEATURES`` |
| the list of all features which are enabled |
| ``DISABLED_FEATURES`` |
| the list of all features which are disabled |
| ``PACKAGES_FOUND`` |
| the list of all packages which have been found |
| ``PACKAGES_NOT_FOUND`` |
| the list of all packages which have not been found |
| |
| For each package type ``<TYPE>`` defined by the |
| :variable:`FeatureSummary_PKG_TYPES` global property, the following |
| information can also be used: |
| |
| ``<TYPE>_PACKAGES_FOUND`` |
| only those packages which have been found which have the type <TYPE> |
| ``<TYPE>_PACKAGES_NOT_FOUND`` |
| only those packages which have not been found which have the type <TYPE> |
| |
| .. versionchanged:: 3.1 |
| With the exception of the ``ALL`` value, these values can be combined |
| in order to customize the output. For example: |
| |
| .. code-block:: cmake |
| |
| feature_summary(WHAT ENABLED_FEATURES DISABLED_FEATURES) |
| |
| If a ``FILENAME`` is given, the information is printed into this file. If |
| ``APPEND`` is used, it is appended to this file, otherwise the file is |
| overwritten if it already existed. If the VAR option is used, the |
| information is "printed" into the specified variable. If ``FILENAME`` is |
| not used, the information is printed to the terminal. Using the |
| ``DESCRIPTION`` option a description or headline can be set which will be |
| printed above the actual content. If only one type of |
| package was requested, no title is printed, unless it is explicitly set using |
| either ``DESCRIPTION`` to use a custom string, or ``DEFAULT_DESCRIPTION`` to |
| use a default title for the requested type. |
| If ``INCLUDE_QUIET_PACKAGES`` is given, packages which have been searched with |
| ``find_package(... QUIET)`` will also be listed. By default they are skipped. |
| If ``FATAL_ON_MISSING_REQUIRED_PACKAGES`` is given, CMake will abort if a |
| package which is marked as one of the package types listed in the |
| :variable:`FeatureSummary_REQUIRED_PKG_TYPES` global property has not been |
| found. |
| The default value for the :variable:`FeatureSummary_REQUIRED_PKG_TYPES` global |
| property is ``REQUIRED``. |
| |
| .. versionadded:: 3.9 |
| The ``DEFAULT_DESCRIPTION`` option. |
| |
| The :variable:`FeatureSummary_DEFAULT_PKG_TYPE` global property can be |
| modified to change the default package type assigned when not explicitly |
| assigned by the user. |
| |
| .. versionadded:: 3.8 |
| If the ``QUIET_ON_EMPTY`` option is used, if only one type of package was |
| requested, and no packages belonging to that category were found, then no |
| output (including the ``DESCRIPTION``) is printed or added to the ``VAR`` |
| variable. |
| |
| Example 1, append everything to a file: |
| |
| .. code-block:: cmake |
| |
| include(FeatureSummary) |
| feature_summary(WHAT ALL |
| FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND) |
| |
| Example 2, print the enabled features into the variable |
| enabledFeaturesText, including QUIET packages: |
| |
| .. code-block:: cmake |
| |
| include(FeatureSummary) |
| feature_summary(WHAT ENABLED_FEATURES |
| INCLUDE_QUIET_PACKAGES |
| DESCRIPTION "Enabled Features:" |
| VAR enabledFeaturesText) |
| message(STATUS "${enabledFeaturesText}") |
| |
| Example 3, change default package types and print only the categories that |
| are not empty: |
| |
| .. code-block:: cmake |
| |
| include(FeatureSummary) |
| set_property(GLOBAL APPEND PROPERTY FeatureSummary_PKG_TYPES BUILD) |
| find_package(FOO) |
| set_package_properties(FOO PROPERTIES TYPE BUILD) |
| feature_summary(WHAT BUILD_PACKAGES_FOUND |

| set_package_properties(<name> PROPERTIES |
| [ URL <url> ] |
| [ DESCRIPTION <description> ] |
| [ TYPE (RUNTIME|OPTIONAL|RECOMMENDED|REQUIRED) ] |
| [ PURPOSE <purpose> ] |
| ) |
| |
| Use this macro to set up information about the named package, which |
| can then be displayed via FEATURE_SUMMARY(). This can be done either |
| directly in the Find-module or in the project which uses the module |
| after the find_package() call. The features for which information can |
| be set are added automatically by the find_package() command. |
| |
| ``URL <url>`` |
| This should be the homepage of the package, or something similar. |
| Ideally this is set already directly in the Find-module. |
| |
| ``DESCRIPTION <description>`` |
| A short description what that package is, at most one sentence. |
| Ideally this is set already directly in the Find-module. |
| |
| ``TYPE <type>`` |
| What type of dependency has the using project on that package. |
| Default is ``OPTIONAL``. In this case it is a package which can be used |
| by the project when available at buildtime, but it also work without. |
| ``RECOMMENDED`` is similar to ``OPTIONAL``, i.e. the project will build if |
| the package is not present, but the functionality of the resulting |
| binaries will be severely limited. If a ``REQUIRED`` package is not |
| available at buildtime, the project may not even build. This can be |
| combined with the ``FATAL_ON_MISSING_REQUIRED_PACKAGES`` argument for |
| ``feature_summary()``. Last, a ``RUNTIME`` package is a package which is |
| actually not used at all during the build, but which is required for |
| actually running the resulting binaries. So if such a package is |
| missing, the project can still be built, but it may not work later on. |
| If ``set_package_properties()`` is called multiple times for the same |
| package with different TYPEs, the ``TYPE`` is only changed to higher |
| TYPEs (``RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED``), lower TYPEs are |
| ignored. The ``TYPE`` property is project-specific, so it cannot be set |
| by the Find-module, but must be set in the project. |
| Type accepted can be changed by setting the |
| :variable:`FeatureSummary_PKG_TYPES` global property. |
| |
| ``PURPOSE <purpose>`` |
| This describes which features this package enables in the |
| project, i.e. it tells the user what functionality he gets in the |
| resulting binaries. If set_package_properties() is called multiple |
| times for a package, all PURPOSE properties are appended to a list of |
| purposes of the package in the project. As the TYPE property, also |
| the PURPOSE property is project-specific, so it cannot be set by the |
| Find-module, but must be set in the project. |

| Legacy Macros |
| ^^^^^^^^^^^^^ |
| |
| The following macros are provided for compatibility with previous |
| CMake versions: |
| |
| .. command:: set_package_info |
| |
| :: |
| |
| set_package_info(<name> <description> [ <url> [<purpose>] ]) |
| |
| Use this macro to set up information about the named package, which |
| can then be displayed via ``feature_summary()``. This can be done either |
| directly in the Find-module or in the project which uses the module |
| after the :command:`find_package` call. The features for which information |
| can be set are added automatically by the ``find_package()`` command. |
| #]=======================================================================] |
| function(SET_PACKAGE_INFO _name _desc) |
| message(DEPRECATION "SET_PACKAGE_INFO is deprecated. Use SET_PACKAGE_PROPERTIES instead.") |
| unset(_url) |
| unset(_purpose) |
| if(ARGC GREATER 2) |
| set(_url "${ARGV2}") |
| endif() |
| if(ARGC GREATER 3) |
| set(_purpose "${ARGV3}") |
| endif() |
| set_property(GLOBAL PROPERTY _CMAKE_${_name}_DESCRIPTION "${_desc}" ) |
| if(NOT _url STREQUAL "") |
| set_property(GLOBAL PROPERTY _CMAKE_${_name}_URL "${_url}" ) |
| endif() |
| if(NOT _purpose STREQUAL "") |
| set_property(GLOBAL APPEND PROPERTY _CMAKE_${_name}_PURPOSE "${_purpose}" ) |
| endif() |
| endfunction() |
| |
| #[=======================================================================[.rst: |
| .. command:: set_feature_info |
| |
| :: |
| |
| set_feature_info(<name> <description> [<url>]) |
| |
| Does the same as:: |
| |
| set_package_info(<name> <description> <url>) |
| #]=======================================================================] |
| function(SET_FEATURE_INFO) |
| message(DEPRECATION "SET_FEATURE_INFO is deprecated. Use ADD_FEATURE_INFO instead.") |
| SET_PACKAGE_INFO(${ARGN}) |
| endfunction() |
| |
| #[=======================================================================[.rst: |
| .. command:: print_enabled_features |
| |
| :: |
| |
| print_enabled_features() |
| |
| Does the same as |
| |
| .. code-block:: cmake |
| |
| feature_summary(WHAT ENABLED_FEATURES DESCRIPTION "Enabled features:") |
| #]=======================================================================] |
| function(PRINT_ENABLED_FEATURES) |
| message(DEPRECATION "PRINT_ENABLED_FEATURES is deprecated. Use |
| feature_summary(WHAT ENABLED_FEATURES DESCRIPTION \"Enabled features:\")") |
| FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIPTION "Enabled features:") |
| endfunction() |
| |
| #[=======================================================================[.rst: |
| .. command:: print_disabled_features |
| |
| :: |
| |
| print_disabled_features() |
| |
| Does the same as |
| |
| .. code-block:: cmake |
| |
| feature_summary(WHAT DISABLED_FEATURES DESCRIPTION "Disabled features:") |
| #]=======================================================================] |
| function(PRINT_DISABLED_FEATURES) |
| message(DEPRECATION "PRINT_DISABLED_FEATURES is deprecated. Use |
| feature_summary(WHAT DISABLED_FEATURES DESCRIPTION \"Disabled features:\")") |
| FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION "Disabled features:") |
| endfunction() |
