Everything builds as expected (from the QtCreator). However, hitting the F5 for deploying (and running) fails:

No target architecture defined in json file

One solution is to copy the android-AndroidApp-deployment-settings.json from the app folder to the root.

Is there a more elegant way by telling the androiddeployqt where to find the deployment-settings.json file (i.e. how to set the --input parameter for the androiddeployqt)? I've played with qt_android_generate_deployment_settings and qt_android_add_apk_target with no avail....
