it seems that your QT-lib cannot be found. Therefore you need to install your qt-libs and the development
packages (check qt-dev or check your distribution's manual to find out what the correct name is...).
OR, you didn't set your QTDIR environment variable correctly. In this case, invoke "export QTDIR=/path/to/qt" before ./configure, replacing /path/to/qt with the correct path where your QT is installed (usually somewhere in /usr/lib/qt)
If you get compiling problems with QGLWidget or something else with OpenGL, check whether your OpenGL libraries are installed
more than once. Sometimes both Hardware accelerated 3D drivers (which you need) and Software implementations of OpenGL are installed. In this case, you need to uninstall the software driver. Try "glxinfo" to find out if you're using MesaGL (software) or your Hardware driver.
If you get an "undefined reference to ..." compiling problem, try to edit the "Makefile" in the "src/" subdirectory AFTER ./configure. Replace the Option "-lqt" in "-lqt-mt" in the line where the LIBS variable is declared (usually line 22).
Some OpenGL problems with SuSE distributions have been reported. See the Forum (in german) for more details or write me (email@example.com) if you speak english.
