How to make work PySide6 binding examples work?

[redtide]

Hello, I tried the 2 {sample|widget}bindings examples and both don't work for the same reason: in configuration I get the following error:

[cmake] -- Using python interpreter: /usr/bin/python
[cmake] CMake Error at CMakeLists.txt:90 (message):
[cmake]   Error: Calling pyside_config.py --shiboken-module-shared-libraries-cmake
[cmake]   returned no output.
[cmake] Call Stack (most recent call first):
[cmake]   CMakeLists.txt:104 (pyside_config)

I'm using Archlinux (Qt 6.6.2) and both PySide6 packages are installed (so also shiboken6).
