+# MACRO_LOG_FEATURE(VAR FEATURE DESCRIPTION URL [REQUIRED [MIN_VERSION [COMMENTS]]])
+#   Logs the information so that it can be displayed at the end

+#   Call this to display the collected results.
+#   Exits CMake with a FATAL error message if a required feature is missing

+# Example:
+#
+# INCLUDE(MacroLogFeature)
