Since this change:

commit 90b4528b846542bfa6f0723487315140b9de17b4

I get this error when trying to run the canvas example:

qrc:/canvas/canvas.qml:57:5: Type Examples.LauncherList unavailable
Examples.LauncherList {
^
qrc:/shared/LauncherList.qml:53:1: module "QtQml.Models" is not installed
import QtQml.Models 2.12
^
qrc:/shared/LauncherList.qml:52:1: module "QtQml" is not installed
import QtQml 2.12

qrc:/shared/LauncherList.qml:53:1: module "QtQml.Models" is not installed
import QtQml.Models 2.12
^
qrc:/shared/LauncherList.qml:52:1: module "QtQml" is not installed
import QtQml 2.12
^

Removing the lines:

 import QtQml 2.12
 import QtQml.Models 2.12

makes this run.
