QtQuick Version 2.15 not installed with Qt 6.0.3

[raphasauer]

Hello everyone. I've build Qt 6.0.3 from source on a Raspberry Pi 3 device, and I'm trying to use QML module QtQuick Version 2.15. I am getting the following error message:

module "QtQuick" version 2.15 is not installed

I've tried installing Qt 6 on a computer running Ubuntu and I could import said module (it was a fresh Ubuntu installation). I think something might be wrong with the import path, so I tried setting QML_IMPORT_PATH to "/home/pi/qt6/qml" (Qt 6 is installed in "/home/pu/qt6"), with no success. Am I missing something? Thanks for your time.
