Install Qt on a Mac with Xcode or QtCreator

Whatever your developpement environnement is, you'll have to maintain the .pro project file yourself. Of course, it can be handled automatically if you're using a PC and have a commercial license of Qt with Visual Studio integration. By experience, I can tell that the project file that can be generated by the integration can become quickly useless if you're using environement variables. The consequence is simple : deployment to other platforms becomes much harder. You can find qmake documention on Qt's website here : qmake manual
In this tutorial we focused on Mac OS X qmake specifications.
