UseQt4.cmake in CVS has been recently patched to reduce the number of include 
directories specified in certain cases.

For example, if QT_USE_QTUITOOLS=1 but QT_USE_XML=0, the QtXml includes and 
defines are no longer added.  If you still want the includes, because you use 
QtXml directly, you can set QT_USE_XML=1.  qmake makes developer that 
explicit too.

Hope that solves your problem.
