Luigi,

Thanks a lot! After installing qt5-qtbase-static, kwin builds fine!

I guess one just has to know that Qt5PlatformSupport must include
qt5-qtbase-static -- the error message generated by
FindQt5PlatformSupport.cmake was pretty useless ...

None of these caused any problems.  cmake.log now has:

-- The following REQUIRED packages have been found:
   (Long list, now including: )
   * Qt5PlatformSupport , Qt PlatformSupport module. , <http://www.qt.io>
 
-- The following RUNTIME packages have not been found:
   * Qt5Multimedia
     Runtime-only dependency for effect video playback

and Qt5Multimedia does not seem to be a must.

Thanks again!
