No, this is a mistake, but it's not your fault. You must have Qt in your PATH. 
The -q option is totally broken under Windows, because it looks like it lets 
you pick a version of Qt which is not in the PATH, but it doesn't really work, 
because the executable built with it won't be executed because of the missing 
DLLs (not in the PATH).

It's not even useful if you have more than one Qt version in the PATH, because 
again there's not -rpath or similar support under Windows, and executables 
will still dynlink against the first version of Qt they find on the PATH.

In fact, the only situation where -q actually works under Windows is when Qt 
is built as static libraries. Which is not how the binary GPL version ships.

So, ignore the (wrong) suggestion of configure.py, and just add Qt's binary 
directory to the path.

Oh btw QTDIR doesn't exist anymore with Qt4, in case you were wondering.
