I should have caught this earlier: for cmake builds you can run ./update.sh instead of ./autogen.sh and there should be no need for autotools/automake/libtool.

Ah, okay. I've pushed a commit to make those changes.

Is autoconf still needed?

I do not know. I will try removing it and see if it still builds.

The previous commit seems to have reduced the total workflow duration from 14-27 minutes to 7 minutes.

Not sure what you are signalling with assigning this to yourself. Should I merge if green or is there more you want to do here?

Sorry for the confusion, in another project I often use the pull request assignees to show who is working on the pull request, and did so here out of habit. This should be good to merge now.
