Qt 5.11+: import of a qrc:/directory not working with QtQuickCompiler

Hi folks,

I want to report a bug: when I use CONFIG += qtquickcompiler in my .pro-file the import statement doesn't work respectively auto-completation fails.

My working tree looks like this:

/other
-/qml
--A.qml
--qmldir
/project
-/myProject
--.pro
--/qml
---main.qml
---qmldir

I want to use now A.qml in main.qml with this import statement:

import "qrc:/other"

My qrc-file looks like this

<!DOCTYPE RCC>
 <RCC version="1.0">
   <qresource prefix="/">
     <file alias="qml/main.qml">main.qml</file>
     <file alias="other/A.qml">../../other/qml/A.qml</file>
 </qresource>
 </RCC>

If I use CONFIG += qtquickcompiler I get an "Unknown component" M300 failure but the application is working! Without CONFIG += qtquickcompiler everything is alright and auto-completion works.

Do you have any idea how to solve this issue, I think that is a bug, because the application is running correctly.

Thanks!
