QML precompilation is supposed to improve application load time but as there’s no guaranteed ABI stability, it breaks the application when upgrading to a newer version of Qt.
See https://doc.qt.io/QtQuickCompiler/qquickcompiler-known-issues.html
This patches disables pre-compilation of QML files during package build to
avoid having to recompile ktouch for every new version of Qt. Compilation will be done automatically at runtime instead.

Launch application with QML compilation disabled.
Check that all UI screens are correctly rendered and controls working.
