Yes, something has to be done to fix that. I would add a check on the cmake 
version with a FATAL_ERROR, like in the Qt 5 config files. It looks like 
bumping the CMAKE_IMPORT_FILE_VERSION alone wouldn't have any effect because 
there is no other code checking it, so that would have to be added. It seems 
easier to me and no worse to add a FATAL_ERROR?
