Hi Martin,

Qt 5 uses platform plugins. When linking statically, the usual procedure [1] 
for linking to static plugins is necessary. However, qmake does this 
automatically for the platform plugin. It adds a special source file to the 
project and links to the static plugin library. If you are using pkg-config 
instead of qmake, you will have to do it explicitly. You might want to look at 
how qmake sets up a simple project.
