In commit f3d978b8a5fb6 the QtQuick version was upgraded to 2.6 (from 2.0 for the mapwidget). This is, apparently, too agressive, as there are still mainstream distributions that are still on Qt 5.5.1 for which 2.6 of QtQuick is too new. And as a sidenote: Qt 5.5.1 was released in October 2015. So partially revert commit f3d978b8a5fb6. Fixes: #978 Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
