Failed to compile xkb_symbols with multiple layout

Hi

We migrate our app to Qt 6.2.3 (attached, the output of the configuration)

But some users cannot start the application, with the following error:

xkbcommon: ERROR: Couldn't process include statement for 'us(simple)' 
xkbcommon: ERROR: Abandoning symbols file "(unnamed)" 
xkbcommon: ERROR: Failed to compile xkb_symbols 
xkbcommon: ERROR: Failed to compile keymap [25778:25793:0223/205624.762296:FATAL:xkb_keyboard_layout_engine.cc(640)] Keymap file failed to load: us-simple Trace/breakpoint trap (core dumped)

I don't reproduce the issue, but it seems to be when several layouts are installed. I also find a similar feedback on another app: https://forums.ankiweb.net/t/anki-2-1-50-beta-1-2/15608/19 (where the user seems to also get this problem since Qt 6). Qt 5 doesn't have this issue.

BR,
