Cargo Features

qcms = { version = "0.3.0", default-features = false, features = ["c_bindings", "neon", "cmyk"] }
default = cmyk, iccv4-enabled

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

c_bindings = libc

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.
