Cargo Features

ogg_next_sys has no features set by default.

[dependencies]
ogg_next_sys = { version = "0.1.3", features = ["build-time-bindgen"] }
build-time-bindgen = bindgen

Requires Clang and slows down the build, but guarantees that the bindings are up to date.
It usually is better to run the generate-bindings.sh script instead

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

bindgen build build-time-bindgen?

Enables bindgen ^0.69.1
