Oh, I see. In perspective, Windows, for example, does not allow mixing 
debug and non debug builds.
I am afraid cmake cannot do what you want.  But you may be able to do it 
with a wrapper bash script.
The idea would be to have two CMakeCache.txt files (one debug, one 
release) and a CMakeFiles directory.  Once you want to compile a single 
file in a directory, you'd rename the debug CMakeCache.txt file and run 
cmake/make.
I'll let others chime in with more elegant solutions.
