References to files & folders within the /lib dir only exist within the ZIP files under releases. Some people, such as myself, prefer to manage their addons with git repos to enable updates.

Please consider adding the missing items from /lib as git submodules.

Thanks,

The majority of dependencies are not even in Git, so that really wouldn't work.
In any case, I would recommend to install the libraries as stand-alone in such a use-case.
