fatal error: ncurses.h: No such file or directory

I can't build the example. cargo run --example chat -- initiator results in the following errors:

error: build failed

I'm sure the issue is just that I need to install ncurses globally or something, but I don't see this documented anywhere in the repo.

Resolved on Ubuntu with sudo apt install libncursesw5-dev. There may be other implicit dependencies.
