# - Macros for generating a summary of enabled/disabled features
#
-# PRINT_ENABLED_FEATURES()
-# Print a summary of all enabled features. By default all successfull
-# FIND_PACKAGE() calls will appear here, except the ones which used the
-# QUIET keyword. Additional features can be added by appending an entry
-# to the global ENABLED_FEATURES property. If SET_FEATURE_INFO() is
-# used for that feature, the output will be much more informative.
+# This module provides the macros feature_summary(), set_package_info() and
+# add_feature_info().
+# For compatiblity it also still provides set_feature_info(),
+# print_enabled_features() and print_disabled_features.
#
-# PRINT_DISABLED_FEATURES()
-# Same as PRINT_ENABLED_FEATURES(), but for disabled features. It can
-# be extended the same way by adding to the global property
-# DISABLED_FEATURES.
+# These macros can be used to generate a summary of enabled and disabled
+# packages and/or feature for a build tree:
#
-# SET_FEATURE_INFO(NAME DESCRIPTION [URL [COMMENT] ] )
-# Use this macro to set up information about the named feature, which will
-# then be displayed by PRINT_ENABLED/DISABLED_FEATURES().
-# Example: SET_FEATURE_INFO(LibXml2 "XML processing library."
-# "http://xmlsoft.org/")
+# -- Enabled features:
+# LibXml2 (required version >= 2.4) , XML processing library. , <http://xmlsoft.org>
+# PNG , A PNG image library. , <http://www.libpng.org/pub/png/>
+# -- Disabled features:
+# Lua51 , The Lua scripting language. , <http://www.lua.org>
+# Foo , Foo provides cool stuff.
#
+#
+# FEATURE_SUMMARY( [FILENAME <file>]
+# [APPEND]
+# [VAR <variable_name>]
+# [DESCRIPTION "Found packages:"]
+# WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND
+# | ENABLED_FEATURES | DISABLED_FEATURES]
+# )
+#
+# The FEATURE_SUMMARY() macro can be used to print information about enabled
+# or disabled features or packages 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_FEATURE_INFO() to add more
+# useful information, like e.g. a download URL for the respective package.
+#
+# The WHAT option is the only mandatory option. Here you specify what information
+# will be printed:
+# ENABLED_FEATURES: the list of all features and packages which are enabled,
+# excluding the QUIET packages
+# DISABLED_FEATURES: the list of all features and packages which are disabled,
+# excluding the QUIET packages
+# PACKAGES_FOUND: the list of all packages which have been found
+# PACKAGES_NOT_FOUND: the list of all packages which have not been found
+# ALL: this will give all packages which have or have not been found
+#
+# 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.
+#
+# Example 1, append everything to a file:
+# feature_summary(WHAT ALL
+# FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)
+#
+# Example 2, print the enabled features into the variable enabledFeaturesText:
+# feature_summary(WHAT ENABLED_FEATURES
+# DESCRIPTION "Enabled Features:"
+# VAR enabledFeaturesText)
+# message(STATUS "${enabledFeaturesText}")
+#
+#
+# SET_PACKAGE_INFO(<name> <description> [<url> [<comment>] ] )
+# 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.
+#
+# Example for setting the info for a package:
+# find_package(LibXml2)
+# set_package_info(LibXml2 "XML processing library." "http://xmlsoft.org/")
+#
+#
+# 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 descibing 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:
+#
+# PRINT_ENABLED_FEATURES()
+# Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIPTION "Enabled features:")
+#
+# PRINT_DISABLED_FEATURES()
+# Does the same as FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION "Disabled features:")
+#
+# SET_FEATURE_INFO(<name> <description> [<url> [<comment>] ] )
+# Does the same as SET_PACKAGE_INFO(<name> <description> <url> <comment> )
