mention dependencies

[adsick]

I'm on Ubuntu 22.10 (wayland) and after cargo build I get an error about missing cairo libraries.

@adsick does xilem#17 solve this for you?

[adsick]

I've switched from Ubuntu to Fedora, so I might check on it. Though if I pull the repo I'd like to run some real examples of Xilem but I don't see them in the repo.

@longmathemagician hmm, no, it does not fix this because there is also Cairo (at least)

[adsick@fedora xilem]$ cargo run

Thank you for checking again! xilem#58 should take care of this for both.

I'm sure there are Linux systems we don't accurately report dependencies for, but we can resolve those as they come up
