IIRC there is a case when the prefix is not computed, perhaps if the
install(EXPORT) command is given an absolute DESTINATION. In cases
when it is computed this information is certainly useful though. I
have several times essentially duplicated that logic by hand in a
FooConfig.cmake file (similar to Michael's response).

It's just an implementation detail that happens to work that way and may
have been easier when first developed.

Yes. It can be computed up front before loading the per-config files.
