Different layout of Qt Quick project on different OSs

Steps to reproduce:

• open an old Qt Quick project (I've used declarative/keyinteraction/focus from Qt4)
• check location of the qml file(s)

For the above mentioned example:

• Linux/Unix lists (beside others):
  • projectName -> QML -> qml -> focus.qml

• Windows lists (beside others):
  • projectName -> QML -> qml/focus -> focus.qml
