Changes for MacOS
- Fixed compilation error for AppleClang 10
- No need to define/use DYLD_LIBRARY_PATH. The native behaviour is to use RPATH
- ROOTConfig.cmake does not define
ROOT_INCLUDE_DIR
- Installation of GaudiConfig.make and Gaudi.xenv in /cmake. With this, there is not need to define Gaudi_ROOT.
