[CMake] Linking against OS X Frameworks

[ML]

HI All,

I am continuing my learning curve.

Consider this block:

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)
		MARK_AS_ADVANCED (CARBON_LIBRARY)
		SET (EXTRA_LIBS ${CARBON_LIBRARY})
		
		ADD_LIBRARY (MoreFilesX ${MOREFILESX_SOURCES} ${MOREFILESX_HEADERS})
		TARGET_LINK_LIBRARIES (MoreFilesX ${EXTRA_LIBS} )
ENDIF (APPLE)

I am trying to link against the Carbon Framework. I know it is not  
working because I am getting errors like:

/Volumes/Data/jtsm/Checkout/Universal GUI/source/thirdparty/OSX/ 
MoreFilesX/MoreFilesX.c: In function ‘FSGetVolParms’:
/Volumes/Data/jtsm/Checkout/Universal GUI/source/thirdparty/OSX/ 
MoreFilesX/MoreFilesX.c:231: error: ‘HParamBlockRec’ undeclared (first  
use in this function)

What am I doing wrong above?

Best,

-Jason
