Duplicate symbols with Qt on iOS

From related issue

I still get another duplicate symbol error:

ERROR: duplicate symbol 'qInitResources_qmake_QtQuick_Controls()' in:
/Users/lbuckel/Qt/6.4.2/ios/qml/QtQuick/Controls/objects-Debug/QuickControls2_resources_1/.rcc/qrc_qmake_QtQuick_Controls.cpp.o 

This time it only lists one .o file. Inspecting the command line shows that it appears multiple times. I think the issue happens because the app depends on a static library which also has a QtQuick controls dependency.
I tried filtering out the duplicate entry but don't know where to do it. At first I modified the rule in qml.qbs to also filter based on the cpp.staticLibraries property but it looks like it does not contain the file at this point? Not sure where it comes from. Any ideas?
