[CMake] CMake's Xcode generator seems to ignore the CMAKE_CXX_COMPILER variable

[Mathieu Malaterre]

I do not have access to a Mac to replicate but I believe you.
Technically this should have worked as I use this trick to specify a
particular compiler instead of the default on a Visual Studio build. I
guess there must be something wrong going on with Xcode. But I cannot
help you anymore on this one.

Good luck
