You are still missing the point that QTDIR is just how configure.py refers
to the Qt root directory in its help text (before it's able to report the
actual value that will be used).

That is that particular binary installer. A standard installation will put
everything under a single directory. Creators of binary installers are free
to put things anywhere they want. configure.py should have enough flags to
allow the locations of the different components to be specified explicitly.

I think using QT_INSTALL_DATA/qsci in the help message rather than
QTDIR/qsci would avoid your confusion.
