I want to use qt.conf to point PyQt to the location of the required Qt dependencies, but it's being ignored. The docs say that Qt expects to find qt.conf in QCoreApplication.applicationDirPath(). When I print this value I see it points to the location of the original Python installation where PyQt was installed to.

Did you build PyQt from source?

Make sure you create a QCoreApplication instance before verifying the qt.conf supplied values.
