I'm trying to review this, but after building and trying to run, I get the following:

Error: Version mismatch. Your configuration file version is
            [3.2.0] but libignition-launch3.so version is [3.1.1].

What configuration file is this? Any ideas of what might be wrong?

Changed the version of the CMakeLists on my local branch to 3.2.0 and that made it work. Still not sure what happened.

PR looks good!

the branch was outdated. I just merged with the latest ign-launch3 branch. b3acc63. It should be on ign-launch 3.2.0 now
