Oops, thanks @jcar87 for having a look!
I added the version in config.yml now.

The Windows build fail seems to be related to the following change:

• Thread support is re-enabled on Windows.

in https://mosquitto.org/blog/2024/10/version-2-0-19-released/.

The mosquitto commit is this one:
eclipse-mosquitto/mosquitto@a3e5deb#diff-1e7de1ae2d059d21e1dd75d5812d5a34b0222cef273b7c3a2af62eb747f9d20a

Looks like the commit adds a dependency to pthreads4w: https://conan.io/center/recipes/pthreads4w.

I try to get this working with a local windows build.

If you are able to troubleshoot this and address this, that would be hugely appreciated!

It seems there's an issue with the CLA as well - can happen when the git history of the PR branch has commits from different authors (or authors with different emails)

Sure!

Turns out the Windows build issue is a known issue in the mosquitto project, here:
eclipse-mosquitto/mosquitto#3139
It is already fixed on master, and should be released as new bugfix version 2.0.21 "this week":
eclipse-mosquitto/mosquitto#3139 (comment)

I would update the PR here then as soon as the mosquitto release is available, hopefully next week.

Excellent, thank you!
