Qt licensing is not a big mystery, nor is it scary, nor does it change all that much over the years:
<https://doc.qt.io/qt-5/qtmodules.html> <https://doc.qt.io/qt-6/qtmodules.html> GPL only, not available under LGPL: <https://doc.qt.io/qt-5/qtmodules.html#gpl-licensed-addons> <https://doc.qt.io/qt-6/qtmodules.html#gpl-licensed-addons> Modules with non L/GPL licenses (most of those being Apache2, BSD, MIT, etc.): <https://doc.qt.io/qt-5/licenses-used-in-qt.html> <https://doc.qt.io/qt-6/licenses-used-in-qt.html>
