Backport of #21839

Testing procedure

  • Green CI
  • Compilation with cmake 4.1.2 (e.g. Alpine Edge) no longer fails for the following apps
    • examples/lang_support/community/javascript
    • tests/pkg/nimble_autoconn_ccnl
    • tests/pkg/cryptoauthlib_internal-tests
    • tests/pkg/cryptoauthlib_compare_sha256
    • examples/networking/misc/openthread
    • examples/networking/misc/ccn-lite-relay
