homebrew support

[dlvhdr]

I like to manage my packages with homebrew.
Fragmenting my packages over different sources is less ideal.
With 1 package manager, I can easily switch computers, or get a list of what I have installed.

I am not familiar with and do not use homebrew and macOS so it would be difficult for me to add this.

I would be happy to accept any PRs though.
