Can't build the example, as following:

Did I miss something？

Yes, I should mention in the readme it depends on font-loader crate which uses a few other libraries.

You can find the instruction from here: https://crates.io/crates/font-loader

sudo apt-get install libfontconfig libfontconfig1-dev

Closing the issue, feel free to reopen it if it's not working.
