split-monitor-workspaces: Build fails (hyprpm)

I’m quite new to the Hyprland ecosystem, apologies as I’m not very familiar with it.

I have the latest Hyprland installed (self-compiled, commit 220144276b8789d05e58df3e0452314c11b64728)

Output from running hyprpm -v add https://github.com/Duckonaut/split-monitor-workspaces:
