title: Link Error with Qt Win Migration Framework: unresolved symbol QWinWidget::staticMetaObject
body: <p>I'm trying to set up the Qt Win Migration framework to use Qt in an existing MFC based application. I want to use the framework as a library, so I ran <code>qmake</code> on the <code>qtwinmigrate/buildlib/buildlib.pro</code> file to create a Visual Studio vcxproj project file. I built the framework as a dll/lib and put the headers in a common include directory. In my MFC project, I added the Qt migration framework's lib as a dependency, included the headers where appropriate and added the code to test the framework. Everything compiles fine, but then I get a linker error:</p>
  
  <blockquote>
    <p>error LNK2001: unresolved external symbol "public: static struct QMetaObject const QWinWidget::staticMetaObject" (?staticMetaObject@QWinWidget@@2UQMetaObject@@B)</p>
