Here's why I asked Albert about this:
- for a long time kdesu builds fine on Mac
 - suddenly it doesn't build any longer
 - I spend time investigating and report a build failure
 - Developer (in this case Ahmad) spends time looking
    - responds that the metainfo.yml says kdesu is only for Linux and FreeBSD
    - Allen says "never mind then"
 - Today another person notices that kdesu no longer builds for Mac
   => repeat ad nauseam

So, to save everyone's time I propose that the CMakeLists.txt notifies 
the user explicitly if project is not supported on current platform.
