Cargo Features

[dependencies]
lmbr = { version = "0.1.0", default-features = false, features = ["lmbr_sys"] }
default = lmbr_sys

The lmbr_sys feature is set by default whenever lmbr is added without default-features = false somewhere in the dependency tree.

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.
