somewhere in there should be a symbolic link that points to the 5.5.x
library instead of the newer one.
but mixing Qt versions is a bad idea...

i would uninstall the 5.5.x libraries completely and install the newer version.

this patch by Jan introduced 2.6 in all QML files.
https://github.com/Subsurface-divelog/subsurface/commit/f3d978b8a5fb6511aa0c1c611cf9b0394fdc125b

i do not understand what this artifact in question is but this limits
the scope of our Qt to at least Qt 5.6.x.

QtQuick versions info:
Qt 5.5 -> QtQuick 2.5
Qt 5.6 -> QtQuick 2.6
Qt 5.7 -> QtQuick 2.7
...
