CMake/macOSMaxAllowed.c: avoid C compiler warning in test code CMake/setup.cmake, technical changes: - optimization: test SDK 15.0.0 first to avoid unnecessary test if true - use a function instead of a macro - use different names for (cached) result variables - use prefix FLTK_ for cache variables Note: the cache variables are marked 'internal': you may need to grep CMakeCache.txt to view them.
