-- A mistake in your config. To quickly test your config without doing a git push and waiting for your code, you can run the Linux build in a Docker container. Try `cibuildwheel --platform linux`.
-- Missing dependency. You might need to install something inside on the build machine. You can do this in `.travis.yml` or `appveyor.yml`, with apt-get, brew or whatever Windows uses :P . Given how the Linux build works, we'll probably have to build something into `cibuildwheel`. Let's chat about that over in the issues!
