How do you link with GtkD in VisualD?

[Enjoys Math via Digitalmars-d-learn]

I'm getting:

For:

import gtk.MainWindow;
import gtk.Label;
import gtk.Main;

void main(string[] args)
{
     Main.init(args);
     MainWindow win = new MainWindow("Hello World");
     win.setDefaultSize(200, 100);
     win.add(new Label("Hello World"));
     win.showAll();
     Main.run();
}

After setting Project Properties > Linker > General > Library 
Files: gtkd
