Users are not supposed to use internal variables like CGAL_CXX_FLAGS_INIT. They contain values that were used to build CGAL. (I need to check whether the files needs to be installed at all.) Users should use "find_package(CGAL ...)". This approach generated too many flags in the past but has been fixed now. Joachim
