I'm not debating that, and I agree that cmake is probably the best way to
automate that for CI. However, I feel we shouldn't compromise the developer
experience.
One of the successes of the core apps project has been the low entry
barrier the QML projects have offered. I would be keen to keep it as it is,
and encourage core app developers to use Qt Creator and dogfood our
toolset, rather than resorting to the command line.
I'd like to find a way to have the best of both worlds: automation for CI
and an optimal app developer experience. From what I gather, the only thing
preventing the previous "run on device" workflow is the prerequisite to
generate the .desktop file. Thus what I'd suggest to keep things simple is
to simply commit a dummy .desktop file to the project, so that Qt Creator
can find it. The CI system could still then generate it from the .in file
an overwrite it.

Note that music is going to be back at being a pure QML app as soon as
media-hub and the mediascanner2 QML bindings land.
