I am running: cmake version 2.6-patch 4

I am confused still. you say if everything is installed in standard  
locations this is unnecessary. Yes, everything is a standard plain  
vanilla OS X install.

So everything you just did above is unnecessary then?

Here is what I have now:

	if (APPLE)
		SET(MOREFILESX_HEADERS source/thirdparty/OSX/MoreFilesX/MoreFilesX.h)
	
		SET(MOREFILESX_SOURCES source/thirdparty/OSX/MoreFilesX/MoreFilesX.c)
		
		FIND_LIBRARY (CARBON_LIBRARY Carbon.framework)
		MARK_AS_ADVANCED (CARBON_LIBRARY)
		
		get_filename_component( FRAMEWORK_DIR ${CARBON_LIBRARY} PATH )
		get_filename_component( FRAMEWORK_NAME ${CARBON_LIBRARY} NAME_WE )
		
		ADD_LIBRARY (MoreFilesX ${MOREFILESX_SOURCES} ${MOREFILESX_HEADERS})
		set_target_properties( MoreFilesX PROPERTIES
		 COMPILE_FLAGS "-F ${FRAMEWORK_DIR}"
		 LINK_FLAGS "-F ${FRAMEWORK_DIR} -framework ${FRAMEWORK_NAME}"
		)
		
	ENDIF (APPLE)

I still get the same compile errors as before. But works using Xcode  
for me.

Is there another resource as I can't find an example of these basic  
things on the wiki. Even Google searching is not really turning up  
much. I did find:http://www.vtk.org/Wiki/ 
CMake:HowToUseExistingOSXFrameworks which is how I structured my first  
example but alas nothing. Even for this list I few people replied with  
ideas none that seem to work.

I would appreciate pointers!
