Hmm...

I'm trying to use CMake for a new project here.  This project (a new
programming language, whose first implementation is in OCaml) is
currently in the very first stages (I have barely more than the lexer
written) and doesn't require anything sophisticated (there's only
1 OCaml file for now ;-).  So my "language support" is very primitive
and rather than fight CMake, I'll probably just switch to something
else :-(
