Fixes a problem in which the UI would fail to compile when the version was not found (qt-5_7_1-x86-msvc2015-static by default), and changing to the correct version through QT Project Settings would clear all the dependencies (possibly a bug in the Qt VS Tools addin). Changing from $(DefaultQtVersion) to any other version doesn't have this problem.
