I recommend treecleaning. This is atrocious beyond belief.
cc'ing QA for their opinion on whether this is suitable software for ::gentoo. Based on the upstream commit message I have my doubts that it is viable to come to an agreement with them on suitably packaging the software, but I could be surprised. There's more stuff here too, by the way. e.g. freetype, harfbuzz, fontconfig: "needed for consistency with macos" https://github.com/wez/wezterm/commit/27cb18f8aeb4074fe76ab14d263754882a1e7c44
