It's HIGHLY RECOMMENDED to build against Qt4 in a *copy* of your CVS working directory as you will still have to run qt3to4 from the qgis root directory (e.g. "/usr/local/Trolltech/Qt-4.0.0/bin/qt3to4 qgis.pro") before you "make", and this change is difficult to undo. Please continue to commit new code that is Qt3.3 compatible, NOT Qt4 only. Note that qgis doesn't actually build against Qt4 yet; this is a change to the build system only, not the code. git-svn-id: http://svn.osgeo.org/qgis/trunk/qgis@3809 c8812cc2-4d05-0410-92ff-de0c093fc19c
