Maybe, hard to tell without actually trying. In any case, this is a one-time, short-term complexity that needs to be solved; I still don't understand why this is "more burdensome on the long-term", whereas current Rust projects tend to require very recent versions of the language (see below), so this will potentially cause problems on every version update. > > > By the way, I checked the version of CMake in CentOS 7.

I also saw this, for CentOS 7 probably. However, even the latest Ubuntu 22.04 LTS and 22.10 provide "only" Rust 1.61, the next release 23.04 *may* have Rust 1.63 and that's not even the latest version...
