# This file defines two macros:
# MACRO_LOG_FEATURE(VAR FEATURE DESCRIPTION URL)
# Logs the information so that it can be displayed at the end
# of the configure run
# VAR : variable which is TRUE or FALSE indicating whether the feature is supported
# FEATURE: name of the feature, e.g. "libjpeg"
# DESCRIPTION: description what this feature provides
# URL: home page
#
# MACRO_DISPLAY_FEATURE_LOG()
# Call this at the end of the toplevel CMakeLists.txt to display the collected results
#
# Example:
#
# INCLUDE(MacroLogFeature)
#
# FIND_PACKAGE(JPEG)
# MACRO_LOG_FEATURE(JPEG_FOUND "libjpeg" "Support JPEG images" "http://www.ijg.org")
# ...
# MACRO_DISPLAY_FEATURE_LOG()
