Hi, I've found that there's a cpp file, and then an object file, generated with the name qrc_<RESOURCE_NAME>. And the object file includes the symbol qInitResources_<RESOURCE_NAME> (See https://doc.qt.io/qt-6/qt-add-resources.html for where <RESOURCE_NAME> comes from, as qt6_add_shaders calls qt6_add_resources)
So the only remaining issue is that just calling qt6_add_shaders in the cmake and Q_INIT_RESOURCE(<RESOURCE_NAME>) in cpp results in Undefined symbol: qInitResources_<RESOURCE_NAME>() So there is still something remaining to do in the cmake that is not handled by the call to qt6_add_shaders.
