[CMake] Work around CMake bug in CMake versions 3.4.x.

Browse Source 
CMake versions 3.4.x crash when using fltk_wrap_ui, a built-in CMake
command. According to the CMake devs this will be fixed in CMake 3.5.

However, since fltk_wrap_ui is no longer necessary (it can replaced by
custom build commands) and some Linux distributions deploy CMake 3.4.x
we decided to use an own replacement function.

This makes sure that FLTK can be built with CMake 3.4.x, but FLTK users
may still have to rewrite their own CMake files to not use fltk_wrap_ui.
