Now you have a complete path to pass to cmake. I am kind of surprised that someone hasn't provided a cmake utility to do this already (since it must be very common), perhaps

   Do it in python. 

    But you don't need to screw with the -I since the compiler always looks inside the frameworks for the include based on #import <OpenGL/gl.h> etc.  That's right the -framework flag is actually ignored at compile time and only needed to link the program so Apple is bogus big time man.

    and why bother with -L etc etc. Just list the damn library by its full path and pass that to cmake?
