[LLVMdev] CMake and Xcode

[Samuel Crow]

Hi Nick,

The CMake devlopers at KitWare work mainly on high-end parallel processing 
supercomputers.  Macs aren't their highest priority usually since their machines 
run primarily Linux and Unix.  If you want to streamline the XCode code 
generator, I'm afraid you'll have to get on the CMake mailing list and talk to 
the developers yourself.

Sorry I couldn't be more help,

--Sam
