BUG: `which` is missing when it's a `shell built-in command`

[VenomousSteam81]

Trying to build on an odd system, a WiiU (see https://linux-wiiu.org), using Adelie Linux (see https://www.adelielinux.org/). For some reason the which command is built into zsh, and I have either modify scripts or install an extra package.

Could there be a way to just use the current shell's builtin which command, and if that doesn't exist, then check for a separate which command, and then if that doesn't exist, just bail and say that which wasn't found? Because currently, you just get spammed with ./git-version-gen: 1: which: not found.

Please let me know if more information is needed.

I'm using the latest commit, as of 12/21/2025 (commit 3ded00c)

Is your binsh a symlink to zsh?

But yeah, odd choice to be using which here, when command -v suffices.
