Cargo Features

[dependencies]
blis-sys = { version = "0.3.0", default-features = false, features = ["static", "parallel-pthreads", "parallel-openmp", "runtime-dispatch"] }
default = static

The static feature is set by default whenever blis-sys is added without default-features = false somewhere in the dependency tree.

parallel-pthreads
parallel-openmp = openmp-sys
runtime-dispatch

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.
