This is example 8, and perhaps a viable solutions of answering the Qt FAQ How to cross-compile a Qt Creator project from Ubuntu to a windows executable?, which follows [1].

Process

For this example, I use a console project that calls the Boost libraries. If you only need the STL, example 1: console application, no libaries shows an easy and successfull approach.

Additional qmake arguments can be supplied in the 'Projects -> Build Settings -> Build Steps -> qmake -> Additional arguments' edit.
