If a qml project is marked as qtForMCU the buildstep will
run the qmlprojectexporter on the currently active qmlproject
when pressing the "Run" button. The output messages of the tool
will then show up in the "Compile Output" panel.
The build step itself can be seen when switching to "Projects"
mode under "Deployment".
