How to import new module to custom layer in QGroundControl

Question

I'm working on a custom build of QGroundcontrol; I've tried to import an existing module (QtQuick.shapes 1.12) to CustomFlyViewVideo.qml. The code builds normally, but when I try to run it I get these errors:

qrc:/qml/MainRootWindow.qml:469 Type FlyView unavailable

qrc:/qml/QGroundControl/FlightDisplay/FlyView.qml:147 Type FlyViewVideo unavailable

qrc:/qml/QGroundControl/FlightDisplay/FlyViewVideo.qml:23 module "QtQuick.Shapes" is not installed
