The `builtin_zeromq` and `builtin_cppzmq` build options are deprecated and will be removed in ROOT 6.42. The ZeroMQ library and its Python bindings are used by the experimental RooFit multiprocessing package, and the ZeroMQ versions it requires (>=4.3.5) are now readily available in the package managers (Conda, Homebrew, and newer Linux distributions).

On Windows, the new RooFit multiprocessing doesn't work anyway.
