Thanks for the heads-up, I had forgotten about this :)

Now, I also adjusted the PKG_CONFIG_PATH variable to adhere to the recommendations of the devguide. We'll see how that fares.

I'll have to look at the CI failure tomorrow; over and out from Scandinavia.

It doesn't works and this is not the temproal issue.
it seems like test_toolsreference the GITHUB_ENV, so if we want to make this pass.
IMHO, we should make test_tools to reference the configure scope variable.

See fix in #102152
