@j-rivero since we don't want to create a -cli package for existing packages, I've moved the ign-launch executable to the non-dev package here. Would that be a problem?

Changes looks good to me.

I think that this was proposed in gazebo-tooling/release-tools#529. I don't see any problem with this more than creating a divergence among the different gz packages, most of them are using -dev.

The whole context and new -cli- packages is described in gazebo-tooling/release-tools#830
