Cargo Features

[dependencies]
ceres-solver-sys = { version = "0.3.0", default-features = false, features = ["system", "source"] }

system default = pkg-config

source = ceres-solver-src

"source" overrides "system"

default = system

The system feature is set by default whenever ceres-solver-sys 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.
