Установка QtWebengineView в Ubuntu: «Не удалось найти подходящую версию dbus. QtWebEngine не будет собран ».

Я пытаюсь установить QtWebEngineView в Ubuntu с проприетарными кодеками.

Работает:

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/usr/local/Qt-5.12.1'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

A suitable version of dbus could not be found.
QtWebEngine will not be built.

Dbus установлен, но как мне получить требуемую версию? Нужно ли обновляться до 19.04?
