to build an X11-using version of FLTK on the Mac OS platform.
This matches the recent support of the --enable-x11 option
by the configure script on the mac.

FLTKConfig.cmake and others have been installed in arch dependent LIBDIR,
but should be in arch independent DATADIR. The result is that you can
always find FLTKConfig.cmake in <prefix>/share/fltk.
This is where "/path/to/fltk" should point to when FLTK is used in external
projects (see README.CMake.txt).
Todo: test if find_package works w/o defining FLTK_DIR when installed
in a standard location.
