The errors with missing cache entires we are seeing are caused by the fact that several conditions needs to be met to allow transwer of cache packages accross different runners (see https://github.com/actions/cache?tab=readme-ov-file#cache-version):

• Zstd needs to be installed on all runners. I am missing adding its installation in the PR.
• enableCrossOsArchive must be added - it's added already.
• restore-keys can help but not always - it's there already.
• The source and the destination path must be "similar" - this is the trickties part to figure out,. there is some normalization happending during the cache and restore but unless it resolves to the same path, it leasd to cashe miss. One can use https://docs.github.com/en/rest/actions/cache#list-github-actions-caches-for-a-repository to debug as suggested on the https://github.com/actions/cache?tab=readme-ov-file#cache-version.

I have myself issues to make it working withing this PR #241

The build folder is uploaded for the reason of debugging when build fails. This should not happen that frequently. If its size is still a problem remove the step entirely as with default false is not usefull at all.

It might be useful when UPLOAD_ARTIFACTS is true and it can be used for debugging.

Overall looks acceptable when the caching issues will be resolved.
