As in Blosc/c-blosc2#472.

The CI error is unrelated, I wonder whether aarch64 is still supported by GitHub.

Some updates in the logs between the last commit to the main branch and this pull request:

• Current runner version: 2.301.1 → 2.303.0
• Runner Image version: 20230227.2 → 20230426.1
• cmake: 3.25.2 → 3.26.3

Perhaps an effect of the CMake version. However, why only for aarch64? It is hard to tell without the actual CMake output.

Looks good.

Regarding aarch64, it used to work, so this might be a temporary glitch?
