IMO we should do this in `run-buildbot` instead. We can add this to the phase at the beginning where we output the `--version` of various tools (`cmake`, `ninja`, etc.). We should be able to use something like `if [ ! -z "${CXX}" ]; then ${CXX} --version; fi`.
Mordante added a comment.
Use @ldionne's suggested approach.
The libc++ pre-commit CI uses Clang nightly builds. Currently it's not
possible to determine the exact version used since CMake doesn't show
this information by default. Instead use the --version flag to get this
information.
