I was figuring this was off the table since it was not in the upstream make.
Is this option still on the table?  If so, what is the path to have it
implemented?

I have to say yuck!, and performance hit.  So, for every path that gets
passed to the compiler you have to launch a process that does string allocation
and conversion.   I do not think this is a realistic solution for larger
projects.  I would not want CMake to generate makefiles with cygpath -w
being invoked multiple times per compiler run.   So, I will restate that
there is no workable solution to use cl with cygwin make anymore.
