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

[Stephan Aiche]

Since you can only choose the following compilers in Xcode (at least  
in the version i have seen)

GCC 3.3 (GCC_VERSION = 3.3)
GCC 4.0 (GCC_VERSION = 4.0)
GCC 4.2 (GCC_VERSION = 4.2)
LLVM GCC 4.2 (GCC_VERSION = com.apple.compilers.llvmgcc42)

it seems reasonable (to me) to give also only this possibilities in  
CMake! Note that XCode offers those option even if some of those  
compilers are not installed. I think Xcode will not work with any  
compiler that was not installed with Xcode, at least I can not find  
any option inside of Xcode.
