But as you indicated, rather than commenting on a PR, it would be better to have CDash post a status to the commit on GitHub with a link back to itself. The biggest barrier to this goal was the fact that CDash didn't actually ever know when a build was done. So we could only ever post bad news (this is what went wrong), not good news (everything passed, hurray). There was no mechanism in place for CTest to say "Okay CDash, that's the last file I'm going to send you for this build". CTest and CDash finally gained this capability as of CMake v3.14 (currently in the release candidate cycle).
> So now that CDash can actually know when a build is done, we need to teach CDash to use GitHub's status API. This is implemented in CDash PR #748. I've already reviewed these changes and they look good to me. I still need to find the time to test it out & make sure the GitHub status gets updated as expected. Once I do that I'll merge this change into CDash, and our goal of linking back to CDash from the commit status on GitHub will finally be achieved.
I see the PR has already been merged. I guess I could take the latest
Docker Hub image and just try it? Not sure of the exact steps needed,
Do I need to add a Webhook to my GitHub repository? Just push or any
event? What does happen when CDash receives the POST request from
GitHub? Since in my setup right now Jenkins is basically in charge of
everything and CDash doesn't really know about anything until it
receives the results from Jenkins I'm unsure how all the pieces fit
