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.

cc build vendor-lgl?
cmake build vendor-lgl?
copy_dir build vendor-lgl?
