QtQuick.Controls installed but can not be used (on Raspberry Pi 4)

[thealse]

I am running Qt nativly on a Raspberry Pi 4 model B and everything seems to be working just fine.

I have installed all I needed like this:

sudo apt install qtcreator qt5-default qt5-qmake qtdeclarative5-dev qtquickcontrols2-5-dev

That is pretty much what I needed, nothing fancy really.
Now I try to explain the error I get.

In my pro file I have added:

QT += quick
QT += quickcontrols2

and then in the qml file:

import QtQuick 2.11
import QtQuick.Window 2.11
import QtQuick.Controls 2.5

But it does not want to run, I am getting the following error:

qrc:/main.qml:3 module "QtQuick.Controls" version 2.5 is not installed

I wanted to use the ProgressBar in the Controls.
Any idea why I can not run the program?

Thanks
