# This file defines the Feature Logging macros.
#
# MACRO_LOG_FEATURE(VAR FEATURE DESCRIPTION URL [REQUIRED [MIN_VERSION [COMMENTS]]])
# Logs the information so that it can be displayed at the end
# of the configure run
# VAR : 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
# REQUIRED: TRUE or FALSE, indicating whether the featue is required
# MIN_VERSION: minimum version number. empty string if unneeded
# COMMENTS: More info you may want to provide. empty string if unnecessary
#
# MACRO_DISPLAY_FEATURE_LOG()
# Call this to display the collected results.
# Exits CMake with a FATAL error message if a required feature is missing
#
# Example:
#
# INCLUDE(MacroLogFeature)
#
# FIND_PACKAGE(JPEG)
# MACRO_LOG_FEATURE(JPEG_FOUND "libjpeg" "Support JPEG images" "http://www.ijg.org" TRUE "3.2a" "")
# ...
