missing icon when macOS from "cargo install"ed binary

[technicalpickles]

Describe the bug

I've been using neovide via the homebrew HEAD recipe for awhile now. I've noticed when it's running, neovide doesn't have its icon, just whatever is the default icon for something compiled:

I've tried the non-HEAD formula, and that seems to happen too.

Also: I'll acknowledge this could be a homebrew specific thing, but figured I'd start here.

To Reproduce
Steps to reproduce the behavior:

1. git clone https://github.com/neovide/neovide.git
2. cd neovide
3. cargo install --path .
4. .cargo/bin/neovide
5. use ⌘ - tab to pull up the command switcher
6. see a default icon

Expected behavior

It should have the N logo, ie the one on the GitHub org

I think I found the reason for this... I had previously cloned and locally installed neovide 🤦🏻

❯ which neovide
/Users/josh.nichols/.cargo/bin/neovide

I was able to fix it with:

❯ cd ~/workspace/neovide/
❯ cargo uninstall
    Removing /Users/josh.nichols/.cargo/bin/neovide
❯ which neovide                                                                                                                                                                             
/opt/homebrew/bin/neovide

Afterwards, when running neovide:

Given that, I think this can be rescoped as "missing icon when macOS from cargo install'd binary". I'll update to reflect that.
