Debug version of Qt Dlls are linked even if we asked for release mode

By default, all our projects are using Qt Dlls in Release, even with the debug configuration.

Using VS Qt addins 2.8.1, when I compile, my dll are now link to Qt5Core.dll and also to Qt5Cored.dll ! Only Qt5Core.dll should be linked, so I suppose that Qt addins 2.8.1 force the link to Qt5Cored.dll ...

With that both dependencies, it crash very quickly inside QApplication initialization when trying to load plugins (like qwindows.dll)
