Windows CI broken

[joto]

Currently Windows builds in the CI don't work due to an issue with wrong hashes in the boost library.

See:

• https://github.com/actions/runner-images/issues/9961
• https://github.com/boostorg/release-tools/issues/64
• https://lists.boost.org/Archives/boost/2024/05/256800.php
• https://github.com/microsoft/vcpkg/pull/38979

Github has closed their issue on this without fix. Not sure whether this will ever be fixed before the next boost version comes out using the correct hashes as far as I understand.

In theory it could be possible to install an older version of boost, but I could not figure out how to do that easily with vcpkg. So we are stuck at the moment.

This has been fixed a few days ago, but now there is a different problem. :-(

Looks like Github finally fixed the Windows images and we are "green" again.
