Cargo Features

[dependencies]
filemagic = { version = "0.13.1", default-features = false, features = ["v5-45", "vendored", "pkg-config", "vcpkg"] }
default = pkg-config, vcpkg

These default features are set whenever filemagic is added without default-features = false somewhere in the dependency tree.

v5-45 vendored?
vendored = cc, v5-45

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.

pkg-config build default
vcpkg build default
cc build vendored?
