Then this should work for libodb-qt:
The only reason I can think of why this might not work is if libtool
doesn't pass the -F option through to clang.

Well, remember, you asked for it: ;-)
If you look around in the documentation, Qt folks tell you to include
it as <QString>. But if you look into Qt's own code, they include
everything as <QtCore/QString> (do as I say, not as I do). If we
follow their advise, to make the whole thing work, we have to add
two -I options: one that goes all the way to .../QtCore (so that our
includes compile) and one to one level up (so that the Qt's includes
compile). Except that Qt 4.x packaged as a framework only added one
-I option, the "level up" one. That's why ODB includes all the Qt
headers with the prefix. They seem to have fixed this in Qt 5.x.
To sum it all up in one word: mess.
