QtCreator does not recognize qml modules from the build folder

The goal originally was to make https://gitlab.com/kelteseth/qml-plausible

easily addable to a CMake project. This works easily with CMake FetchContent_Declare, but QtCreator does not show any support for highlighting with this method. My guess is this is because it gets downloaded into the bin folder? See example project:

CMakeFetchContentQml.zip

 Making this workable would be really neat, because this would mean having a fast way to add custom qml modules to every Qt projects
