Ah, this reminds me of one of the things on my wish list for FindQt4:
Modern Qt4 uses a Mac-framework compatible layout, such that in order to
e.g. include QObject header, you would do

#include <QtCore/QObject>

If a project is using this include-practice, the module could cut down
considerably on include-paths. Also, it makes the framework detection
ugliness on Mac unnecessary.

So, here my wish: similar to QT_USE_IMPORTED_TARGETS, introduce
QT_USE_FRAMEWORK_INCLUDES (or similar) which only adds the directory
containing all the QtCore, QtGui, QtXml, ... header directories to the
include-path.
