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., <http://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
|
|
|
|
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.

)
|
|
|
|
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>
|
|
|
|
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``.
|
|
|
|
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.
|
|
|
|
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)
|

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 severly limited. If a ``REQUIRED`` package is not
|
|
available at buildtime, the project may not even build. This can be
|
|
combined with the ``FATAL_ON_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.
|
|
|
|
Example for setting the info for a package:
|
|
|
|
.. code-block:: cmake
|
|
|
|
find_package(LibXml2)
|
|
set_package_properties(LibXml2 PROPERTIES

add_feature_info(<name> <enabled> <description>)
|
|
|
|
Use this macro to add information about a feature with the given ``<name>``.
|
|
``<enabled>`` contains whether this feature is enabled or not. It can be a
|
|
variable or a list of conditions.
|
|
``<description>`` is a text describing the feature. The information can
|
|
be displayed using ``feature_summary()`` for ``ENABLED_FEATURES`` and
|
|
``DISABLED_FEATURES`` respectively.
|
|
|
|
Example for setting the info for a feature:
|
|
|
|
.. code-block:: cmake
|
|
|
|
option(WITH_FOO "Help for foo" ON)
|
|
add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.")

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.
