Resource in Static Library using Qt

If you will use resources in a static library, you have to initialize it first, like following: 
http://qt-project.org/doc/qt-4.8/resources.html

  int main(int argc, char *argv[])
  {
      QApplication app(argc, argv); 
      Q_INIT_RESOURCE(graphlib);
      ... 
      return app.exec(); 
  }
