title: Why I cant debug qml from qt creator?
body: <p>I installed the last Qt 5.12.2 . Then I open the cmake project via Qt Creator.</p>
  
  <p>First I see a huge count on the intellisence issues: from "udeclared identifies of nullptr" to errors with each type "unknown type name".</p>
  
  <p>The build proceeded successfully and I receive correct binary.</p>
  
  <p>But any breakpoint marked as "Unclaimed breakpoint" and I cant debug any .qml (the .cpp could be debug)</p>
  
  <p>So why it happens and how to debug the QML? (this future is still supported?)</p>
  
  <p><strong>UPDATE</strong>: The "QQmlDebuggingEnabler enabler;" and "doc.qt.io/qt-5/qtquick-debugging.html" doesnt helps :(</p>
  
  <p><strong>UPDATE2</strong>: @Amfasis - </p>
