    Description

      Steps to reproduce:

      1. Open any widgets example or create simple Qt Widgets application using wizard.
      2. Try to build the app on X11 linux with Qt 6.5.0 desktop.

      Expected: The application runs.

      Actual: The application could not be built - error appears: 

      qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.Available platform plugins are: wayland, eglfs, minimalegl, offscreen, minimal, linuxfb, vkkhrdisplay, xcb, vnc, wayland-egl.

      Reproducibility:  100%

      NOTES: Not reproducible on Qt 6.4.3 and Qt 6.2.8 - all 3 versions were installed in the same way.
