I might have a look at it when coming back from vacation if the packager I used last time did not update the library (I have no reliable Internet access right now, yes this is still possible nowadays :)). But I was not in a hurry as there is no Qt package compiled with MSVC2015 yet, so we still have a strong dependency on MSVC2013.
