Unfortunately, owing to the way that the WRAP_TCL etc commands have been 
implemented, you can't remove a source file after the wrapper command has 
executed (tcl link error). I put the INCLUDE before the WRAPPER commands 
because one needs to remove them first.

Here's my vtknew IO localuseroptions.cmake file (I'm still tweaking the others)

# remove these from the source list

IF (VTK_WRAP_GUI)
   INCLUDE (GUIWrapping.cmake)

   ADD_LIBRARY(vtkCommonGUI CommonGUI_SRCS )
   TARGET_LINK_LIBRARIES (vtkCommonGUI vcl50 BvtkComponents BvtkParam)
ENDIF (VTK_WRAP_GUI)



you can experimant with adding this sort of thing (I tried already...) but 
it wont work "after the fact"
