I am using QT 5.9.1 while working on Mac OS. My project is a mobile application with C ++ logic and a UML QML layer. All QML files are included in the qml.qrc file, so there is in my .pro file
RESOURCES + = qml.qrc
Inside qml.qrc there is a list of all resource files that I use in Project, such as images, icons, and QML files, in QT Creator it displays OK:

As you can see, some QML files are located in the ROOT qml.qrc path, while other files are in subfolders, for example. "QRC: / Elements /".
