Thanks a lot for taking the time to create the PR, we appreciate it!

I have some comments, specially regarding the chosen prerelease version scheme, but otherwise the recipe looks fine :)

[AbrilRBS]

Note that this version, as per semver semantics, would come before 1.17.1, that is, 1.17.1-36 < 1.17.1, which I don't think is the intention here!

We should clarify if upstream is expecting to release a new version soon with this fix, else we'll need to roll our own schema for this

[winternet]

Nice catch, you're absolutely right. Since the latest commit was two years ago and the repository is more or less in hibernation mode, I don't think there will be a tag or release soon. Is there the possibility to refer to a specific commit without the need to assign it a version?

[AbrilRBS]

Yes! We can set this version to 1.17.1.cci.YYYYMMDD for the date of the latest commit, which is our way of indicating that the version comes from a specific commit and is not tagged

[winternet]

Thanks, I adapted the 1.17.1-36 version according to the proposed scheme and removed the (faulty) 1.17.1 version.

Thanks for your review - very appreciated. I have some questions regarding the failing builds:

• Linux: Builds fine on my system but on CI the test would not build (undefined reference to symbol 'pthread_create@@GLIBC_2.2.5') which suggests that pthreads is missing - do you have a hint what could be missing?
• Windows/macOS: Is it mandatory to fix the builds or would it be ok to provide the package only for Linux?
