Ok, so what you said earlier:

... was not the full story.

The IMPORTED_SONAME should match the shared library id, except for APPLE 
FRAMEWORKS, in which case it should be the outputName? Are there other 
exceptions? 

If creating IMPORTED targets by hand is a valid usecase (I think it is - 
FindQt4 does it too, and there are benefits for other Find modules to do 
so), I could try to document this more clearly.

Thanks,

Steve.
