In addition to that, if you use the CVS version of CMake, you can
specify a particular version of Qt:

FIND_PACKAGE( Qt4 4.4.3 )

That means "prefer 4.4.3" to any other version. If you add EXACT to
that, it will only accept Qt 4.4.3:

FIND_PACKAGE( Qt4 4.4.3 EXACT )

You can also use the COMPONENTS syntax instead of SET(
QT_USE_component) to say what components you want:

FIND_PACKAGE( Qt4 COMPONENTS QtGui QtXml QtNetwork )
