Don't find_package(ament_index_cpp ..) if RMW is configured at build-time

As per subject.

Should fix #209.

I'm currently on Humble, so if this could be backported to humble, that would be :+1:

Not sure what to make of the buildfarm build failing.

We need to do some Rolling releases. I'll do those in a bit.

Well, I don't know why the Rpr job is failing; I can't reproduce that locally. I'm going to run CI on this, and if that is good, merge.

CI:

• Linux
• Linux-aarch64
• Windows

Looks like the Jenkins agents get shut down before the build completes?

Sigh, yes. The aarch64 nodes have been flapping a bit lately. They automatically restart, but the tracking badge doesn't follow that. Updated now.

CI looks good here (the yellow jobs just have a CMake warning, and that was fixed elsewhere). So going ahead and merging this one.

[gavanderhoorn]

thanks.

Could this one also be backported to Humble?
