The defaults (*) are usually acceptable.  Here is a short explanation of
each option:

 *  -release ........... Compile and link Qt with debugging turned off.
    -debug ............. Compile and link Qt with debugging turned on.

 *  -shared ............ Create and use a shared Qt library (libqt.so)
    -static ............ Create and use a static Qt library (libqt.a)

    -qt3 ............... Configure for use with Qt 3.x
