# 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 INCLUDE_QUIET_PACKAGES is given,

# packages which have been searched with find_package(... QUIET) will

# 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: this should be the homepage of the package, or something similar.
|
|
||||||
# Ideally this is set already directly in the Find-module.
|
|
||||||
#
|
|
||||||
# DESCRIPTION: A short description what that package is, at most one
|
|
||||||
# sentence. Ideally this is set already directly in the Find-module.
|
|
||||||
#
|
|
||||||
# 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.
|
|
||||||
#
|
|
||||||
# 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.

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
|

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 ``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 ``REQUIRED`` has not been found.
|
||||||
|
|
||||||
|
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)
|
||||||
|

|
|

|
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.
|
||||||
|
|
||||||
|
|
||||||
|
``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.
|
||||||
|
|
||||||

||||||
|

|
||||||
