[CMake] CMAKE_CXX_COMPILER: problem setting

[Steven Van Ingelgem]

Hi Bill,


I found the reason, but I have no idea why:
in the unix makefiles on mac it uses -isystem to include the
directories (as it does on a Linux), but for XCode it uses -I. And
with -isystem it gives problems, but if I change those calls in
flags.make to -I, it works like a charm...


Maybe you can help me a little further with that?


Thanks!
