[CMake] Flag ordering: cmake -P -D vs cmake -D -P

[Mathieu Malaterre]

Hello,

  This is a follow up on :

http://public.kitware.com/pipermail/cmake/2006-June/009652.html

  It would be super nice if cmake 2.4.7 could handle correctly either
possibility. Or at least clearly add that in the documentation.

thanks,
