Well it doesn't work on my Windows command prompt.  I thought it failed 
in 2.4.2 because a simple cmake -P script does not create a 
CMakeCache.txt, and -D was for modifying the cache.  Here's my test script:

and here's my command line:

E:\devel>cmake -P bwah.cmake -DDEPRESSING=killme


E:\devel>
