Beats me too.
Well, not entirely. Qt has been moving away from a single monolithic build to separate components, and indeed if you look at the Debian packaging of Qt5.3, there are separate package bundles corresponding to qtbase, qtsvg, qtx11extras etc. that have to be built and installed in an appropriate order. With that in mind, there is indeed a use case where required headers have to be found in the target header path.

I started out tongue-in-cheek, but lost myself in thought experiments ;)
