The variables are CMAKE_OSX_ARCHITECTURES, CMAKE_OSX_DEPLOYMENT_TARGET  
and CMAKE_OSX_SYSROOT. The ones you mentioned are the defaults to pre- 
populate the cache and get assigned to the variables I mentioned  
before you have any chance of changing them.

However, I strongly advice NOT to set them in your CMakeLists.txt,  
unless it really is required. Let the user set those variables in the  
cache.
