Well, that maybe for QT, but the problem is for the FIND_PROGRAM
in cmake we had to pick one, and most of the time you want the
one in the path.   However, it would seem that if I was going to
develop a QT program, and I set my QTDIR, then I went to bulild
something with qmake, and I typed qmake, and I got the 3.0 qmake
which would not work.

So, for FindQT we could do something like this:

FIND_PROGRAM(QT_QMAKE_EXECUTABLE NAMES qmake PATHS
  $ENV{QTDIR}/bin 
   NO_SYSTEM_PATH
) 
FIND_PROGRAM(QT_QMAKE_EXECUTABLE NAMES qmake PATHS
"[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\4.0.0;InstallDir]/bin"
"[HKEY_CURRENT_USER\\Software\\Trolltech\\Versions\\4.0.0;InstallDir]/bin" 
  $ENV{QTDIR}/bin 
  ${QT4_PATHS} 
)
