+# FeatureSummary

-# add_feature_info().
-# For compatibility it also still provides set_package_info(), set_feature_info(),
+# 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 library. , <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.

-#                          | ENABLED_FEATURES | DISABLED_FEATURES]
-#                   )
-#
-# 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
-#
-# 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.
