In 50bf54c invoking windeployqt was only required in release mode as
MDILXapCompile was not invoked for debug builds with Visual Studio 2013.
However, Visual Studio 2015 invokes MDILXapCompile for debug and
release. Hence we have to use this workaround unconditionally.
Also we cannot limit this to msvc2015 host specs only, as older projects
still might be loaded with Visual Studio 2015 causing the build to
break.
