# Macros for generating a summary of enabled/disabled features
|
|
#
|
|
#
|
|
#
|
|
# This module provides the macros feature_summary(),
|
|
# set_package_properties() and add_feature_info(). For compatibility it
|
|
# also still provides set_package_info(), set_feature_info(),
|
|
# print_enabled_features() and print_disabled_features().
|
|
#
|
|
# These macros can be used to generate a summary of enabled and disabled
|
|
# packages and/or feature for a build tree:
|
|
#
|
|
# ::
|
|
#
|
|
# -- 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.

|
#
|
|
#
|
|
#
|
|
# 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
|
|
# ``OPTIONAL_PACKAGES_FOUND``
|
|
# only those packages which have been found which have the type OPTIONAL
|
|
# ``OPTIONAL_PACKAGES_NOT_FOUND``
|
|
# only those packages which have not been found which have the type OPTIONAL
|
|
# ``RECOMMENDED_PACKAGES_FOUND``
|
|
# only those packages which have been found which have the type RECOMMENDED
|
|
# ``RECOMMENDED_PACKAGES_NOT_FOUND``
|
|
# only those packages which have not been found which have the type RECOMMENDED
|
|
# ``REQUIRED_PACKAGES_FOUND``
|
|
# only those packages which have been found which have the type REQUIRED
|
|
# ``REQUIRED_PACKAGES_NOT_FOUND``
|
|
# only those packages which have not been found which have the type REQUIRED
|
|
# ``RUNTIME_PACKAGES_FOUND``
|
|
# only those packages which have been found which have the type RUNTIME
|
|
# ``RUNTIME_PACKAGES_NOT_FOUND``
|
|
# only those packages which have not been found which have the type RUNTIME
|
|
#
|
|
# With the exception of the ``ALL`` value, these values can be combined
|
|
# in order to customize the output. For example:
|
|
#
|
|
# ::
|
|
#
|
|
# 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:
|
|
#
|
|
# ::
|
|
#
|
|
# feature_summary(WHAT ALL
|
|
# FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)
|
|
#
|
|
#
|
|
#
|
|
# Example 2, print the enabled features into the variable
|
|
# enabledFeaturesText, including QUIET packages:
|
|
#
|
|
# ::
|
|
#
|
|
# feature_summary(WHAT ENABLED_FEATURES
|
|
# INCLUDE_QUIET_PACKAGES
|
|
# DESCRIPTION "Enabled Features:"
|
|
# VAR enabledFeaturesText)
|
|
# message(STATUS "${enabledFeaturesText}")
|
|
#
|
|
#
|
|
#
|

|

#

# [ DESCRIPTION <description> ]

# 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: 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.
|
|
#
|
|
#
|
|
#
|
|
# Example for setting the info for a package:
|
|
#
|
|
# ::
|
|
#

# find_package(LibXml2)
|

# set_package_properties(LibXml2 PROPERTIES

# ADD_FEATURE_INFO(<name> <enabled> <description>)
|

#
|

|
|
# <name>. <enabled> contains whether this feature is enabled or not,
|
|
# <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:
|
|
#
|
|
# ::
|
|
#
|
|
# option(WITH_FOO "Help for foo" ON)
|
