To make things more clear (because I assume if he asked it he doesn't know how 
it works), cmake's CONFIGURE_FILE() will replace not only "#cmakedefine" but 
any variable placeholder of the form @VAR@ or ${VAR} (if the "@ONLY" option 
is not provided).

Just read the cmake manual page on CONFIGURE_FILE.
