CMake Error at CMakeLists.txt:36 (message):
  Building Celix using CMake 3.3 and makefiles is not supported due to a bug
  in the Makefile Generator (see Bug 15696).  Please change the used CMake
  version - both, CMake 3.2 and CMake 3.4 are working fine.  Or use a
  different generator (e.g.  Ninja).
