title: QT QML resource files do not recompile after changes
body: <p>I'm using QT 5.9.1 working on Mac OS. My project is mobile App with C++ logic and QML UI Layer. All QML files are included into qml.qrc file, so in my .pro file I have</p>
  
  <p><strong>RESOURCES += qml.qrc</strong></p>
  
  <p>Inside qml.qrc there is a list of all resource files I use in Project, such as pictures, icons and QML files, in QT Creator it's displayed OK:</p>
  
  <p><a href="https://i.stack.imgur.com/UYBGq.png" rel="noreferrer"><img src="https://i.stack.imgur.com/UYBGq.png" alt="List of source files"></a></p>
  
  <p>As you can see some QML files are located in ROOT path of qml.qrc when other files are in subfolders , e.g. "qrc:/Elements/".</p>
  
  <p>So problem is that whenether I make changes in Files that located in root of qml.qrc - they are normally recompiled when I press build, rebuild, or clean and build, so I can see my changes. As a result in my build directory I see that qml_qrc.cpp (as I understand this file contains cpp representation of my resource files and is used to compile them) file is refreshed,my changes are applied and everything is OK.</p>
  
  <p>Here is just piece of this file, which begins with cpp hex representation of MainPage.qml resource file.</p>

  <p>But if I change those resource files located in subfolders, qml_qrc.cpp file is not refreshed, so my resource files are not rebuild, even if I try Clean, then rebuild. Even if I do "run qmake" manually and then rebuild. The only thing helps in this situation - to manually delete build folder (or to be more precisely you can just delete qml_qrc.cpp file). So then pressing "Build" will create new qml_qrc.cpp file, which will contain correct code, with changes I've done in my resource files. </p>
  
  <p>Can someone help me or explain why this happens and what can I do in this situation? deleting manually and rebuilding is annoying, but placing all resource files in root path of project is also not a good decision...</p>
  
  <p>I also tried to paste</p>
  
  <p>update qml</p>
  
  <p>qml_scenes.depends = $$PWD/QML Files/OrdersPage.qml</p>
  
  <p>qml_scenes.commands =
  QMAKE_EXTRA_TARGETS += qml_scenes</p>
  
  <p>as was described <a href="https://stackoverflow.com/questions/47810450/why-are-changes-to-the-qml-code-sometimes-not-reflected-when-hitting-run-and-h">here</a>, but it didn't help </p>
