Situation:
- Application links dynamically to Qt
- Loads plugins which link statically to Qt
- All instances use QML
- When the plugin UI is instantiated, the QML resources of the Application are tried to be imported
Debug traces:

Analysis:
- Looking into the default import paths logic, the QML Engine by default (also in the plugin use case!) adds the Application's executable directory to the QML import paths
- See https://github.com/qt/qtdeclarative/blob/v6.8.0/src/qml/qml/qqmlimport.cpp#L1537-L1596
As an exercise, I will provide the proposed patch via Gerrit.
