Once again I answer my own question!

layouts are provided by qtdeclarative5-quicklayouts-plugin

The nomenclature seems inconsistent, qtdeclarative5-quicklayouts-plugin
on the one hand, libqt5qml-quickcontrols on the other.

qtdeclarative5-quicklayouts-plugin does depend on
libqt5qml-quickcontrols, but in my case, using
Quick.Controls.ApplicationWindow, the dependency goes in the other
direction.  I couldn't see anything in
qtdeclarative5-quicklayouts-plugin which depends on Quick.Controls.
