If you are using the Qt Visual Studio Add-in:
1) You should open "Qt options" window and use "Add" button on the "Qt versions" tab.
2) Right click on your project in the "Solution Explorer", choose "Change project's Qt version" and select the correct Qt version. $(QTDIR) should be used automatically.

If you are not using Qt Visual Studio Add-in (It's unavailable for the express versions of VS), try this solution.
