there is a difference here in that the include directory properties are a new 
feature, so this wouldn't break existing code.
It would force developers who make use of the new feature to split exported 
targets into individual components and support components properly in their 
Config.cmake files.

I'm ok with it if the error occurs at cmake time, I'd be even more ok if a 
successful find_package() would continue to tell me that everything I need has 
been found.
This is the case with find-modules, I see this as a good thing.
