Propose for Enhancement: Color output for feature_summary
CMake can produce Makefile that show a colored message on build, when specify -DCMAKE_COLOR_MAKEFILE. I'd like to propose similar effect for FeatureSummary module, and like to contribute it.
Current FeatureSummary just show a simple list of features and packages. It may be a pretty good to show bright messages for found one, and dark messages for not found one.
Color version of Makefile uses ANSI escape sequence such as ESC[32m, we can reqlize it as same way in FeatureSummary.
