I had missed this error message from cmake:

	CMake Warning:
	  Manually-specified variables were not used by the project:
	
	    MARBLE_INCLUDE_DIR

Is this expected? If yes, what would be the recommended way to specify
another path for marble's header files? I note that MARBLE_INCLUDE_DIR
is still used in build.sh.

Cheers.
