Thanks Milan! Installing qml6-module-qt-labs-settings didn't resolve the reported error, though, but helped me get webcamoid running nonetheless.
To resolve `module "QtQuick.Controls" plugin "qtquickcontrols2plugin" not found` warning, qml6-module-qtquick-controls needs to be installed. But wait! There's more! Next warning: module "QtQuick.Layouts" is not installed Resolution: install qml6-module-qtquick-layouts Next warnings: Now we get `module "Qt.labs.settings" is not installed` as well as `module "QtCore" is not installed` which is resolved by installing qml6-module-qt-labs-settings plus qml6-module-qtcore. We're not done yet, though! Next warning: module "Qt.labs.platform" is not installed Resolution: install qml6-module-qt-labs-platform Now, webcamoid starts, but even more dependencies may be required which I already had installed. Fortunately, the missing module names reported mapped to a package name consistently. Try apt install qml6-module-<TAB><TAB> to see all available.
