This helps with other IDE's that handle CMake better than QMake

This feels like a hack - they are already inserted somehwere else
in the plugin folder.

Create a new Target FactControls, and add a custom target for the
Qml in the folder.

This creates a fake target that adds the Qml sources to the CMakeProject
this let's IDE's that read CMake files to display the files on the
project viewer

* CMake: Set warning level and disable -Waddress-of-packet-member

Mavlink fails terribly on the check for -Waddress-of-packet-member
but this is not a problem of QGC, if I don't remove this warning
it's impossible to look at the terminal for QGC warnings.
This needs to be fixed however, but this is not the place.
