[CMake] Warning with ccmake 2.8.4

[Andreas Kelle-Emden]

Hi list,

I set the variable CMAKE_PREFIX_PATH on the command line
so that CMake can find some Config files installed in a
non-standard directory.
The makefile generator prints the following warning:

CMake Warning: The variable, 'CMAKE_PREFIX_PATH', specified manually, 
was not used during the generation.

Actually, the variable IS used, but only for finding the ***_DIRs.

Best regards,
Andreas
