Thanks Sergio for looking into that. I think Nekhelesh's point was that
before the cmake migration it was much easier to test pure QML apps. Adding
cmake to the mix now requires a build step that needs to be done outside of
Qt Creator to generate the .desktop file.

Before, pressing Ctrl+F12 would just copy the files over to the device and
run the app. Granted, this would not test confinement, but for rapid app
development (and especially if it's an app that has been tested to work in
confinement) it is very convenient. App confinement could then be tested
with a click build and install before release.

But I think the main point here is that we've broken Qt Creator's workflow
for pure QML apps by introducing a build step as a requirement. Can we
still get the best of both worlds, perhaps by adapting Qt Creator's scripts
(e.g. the one that is called by pressing Ctrl+F12)?

Would you mind filing a bug for that? I also agree that resolving this
dynamically would be much better than hardcoding it to a given .desktop
file name.

I'm not sure I can follow this one. Could you elaborate on what's needed to
do here, whether fix the cmake rules or the Qt Creator scripts?

Thanks.

Cheers,
David.
