Write it in CMake script.  That's how you get out of these problems
without introducing new language dependencies.  You'll have to invoke
a 'cmake -P' shell, probably using EXECUTE_PROCESS before you do the
rest of your configuration time stuff.  'cmake -P' shell is necessary
because you can't introduce dynamic dependencies to CONFIGURE_FILE,
like file writing and globbing and so forth.  You have to get all this
work done before your real, main cmake sees it, so that it's static
and decided by that time.

I have CMake scripting examples in the Chicken Scheme build,
http://www.call-with-current-continuation.org , but I'm using
ADD_CUSTOM_COMMAND at build time, not configuration time.  Not what
you want.
