The incorrect behavior is left from the earliest days of CMake.
Fixing this outright will change existing build behavior.  We
would have to do this with a CMake Policy.  However, Steve Wilson
is working on first-class Objective C and Objective C++ support:

 http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/9371

That will resolve this in a compatible way by allowing projects
to enable OBJC and/or OBJCXX languages to get .m and .mm sources
compiled properly.

Steve, do you have the work-in-progress topic published somewhere?

Thanks,
