But it does work! I've tested it several times with much success! I'm not
sure what you're saying about *.c, *.cxx, and *.h. Could you explain? Also,
I won't have access to a bash shell on Windows. I'd rather CMake just work
instead of trying to find silly workarounds like this.

I'll put in the feature request for {} and at some point in the future it
can be addressed.
