How can I avoid the GdbEngine when trying to debug a BareMetal device in QtCreator?

[betzw]

I would like to use the BareMetal plugin from Tim Sander in order to debug an openocd based external board with QtC as IDE, but instead of running my custom init commands QtC seems to run the standard GdbEngine as if I where trying to start debugging by attaching to a remote debug server and bypassing completely the BareMetal setup of my kit.
Any ideas what I am missing?

Thanks in advance,
Wolfgang

P.S.: I am running QtCreator 3.3.2 (opensource) (based on Qt 5.4.1 (GCC 4.6.1, 64 bit)) on Linux with BareMetal plugin version 3.3.2 and am working on a project based on CMake.
