Cargo Features

gbm-sys has no features set by default.

[dependencies]
gbm-sys = { version = "0.3.0", features = ["use_bindgen", "update_bindings"] }
use_bindgen build update_bindings? = bindgen

Enables proc-macro2 and regex

update_bindings = use_bindgen

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.
