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}") +# +# +# +# +# +# :: +# +# 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: 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 +# DESCRIPTION "A XML processing library." +# URL "http://xmlsoft.org/") +# +# +# +# :: +# +# set_package_properties(LibXml2 PROPERTIES +# TYPE RECOMMENDED +# PURPOSE "Enables HTML-import in MyWordProcessor") +# ... +# set_package_properties(LibXml2 PROPERTIES +# TYPE OPTIONAL +# PURPOSE "Enables odt-export in MyWordProcessor") +# +# +# +# :: +# +# find_package(DBUS) +# set_package_properties(DBUS PROPERTIES +# TYPE RUNTIME +# PURPOSE "Necessary to disable the screensaver during a presentation" ) +# +# +# +# :: +# +# 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, +# <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) +# add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.") +# +# +# +# +# +# The following macros are provided for compatibility with previous +# CMake versions: +# +# :: +# +# 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().
