[Cmake] Patch for at command-line parm

[Schumacher, Gordon]

Sorry this took me so long; it's been pretty crazy here.

Anyway, this should do it... let me know if you run into problems with this.

Next stop: trying to build a version of CMake that will run under DJGPP!
(Yes, I'm insane.  But I've not been left much choice on this one... we
probably *have* to be able to build in a real DOS environment!  Yuck.)

Patch follows:
