SYSTEM will include the dir using -Isystem <path> instead of -I<path> which will silent warnings. It is really, really useful when doing development, so it should be kept for all cmake versions that support it. Suggested way forward:

1) lower required cmake version to 2.8.11
2) write a macro that wraps target_include_directories and uses SYSTEM on newer cmakes.

Feel free to track that in a new bug.
