You would need to examine the cmake logs (CMakeOutput.log +
CMakeError.log) and the CMakeLists.txt in this subdir to see how this
check is being done. Maybe the wrong compiler is being used for the
check; maybe it's buggy in some other way.

That's coming from a different CMakeLists.txt (which apparently works
correctly since the same output is in the log of the failing build).

The current version fails on the buildbot for all OS versions except
Ventura. The logs that are still available for x86_64 show the same
error as GitHub Actions.
So it appears that pushing the update won't make it more broken, but it
still is quite broken. At the very least, binaries won't be built for
most platforms, and if it fails on the buildbot then it will most likely
fail for local builds too on at least some subset of machines.
