[CMake] CMakeCache Files

[Michael.Schmidt at L-3com.com]

I'm a newbie with cmake, and I wanted to clarify a couple things.  From
what I understand, there's no command to clear CMakeCache files.  If I
add a new file or change the CMakeLists, then I have to delete the
CMakeCache files manually.  If I change an option using ccmake, do I
have to remove the cache files before "generating"?

Thanks,
Mike
