Qt is not relocatable, the path to the install location is hardcoded into the tools. If you build a Qt project with qmake it'll also generate compiler commands that point to the non-existing install location. You can make the Qt installation relocatable by adding a qt.conf file and qmake will pick this up as well, see the Qt docs for more information: http://qt-project.org/doc/qt-4.8/qt-conf.html.

There are various ways of customizing the structure and the structure can be different across platform. Andreas
