The wheels distributed on pypi only contain the licenses of the wrapper code, but don't include the license of the vendored code in lz4libs. I think this file https://github.com/lz4/lz4/blob/dev/lib/LICENSE
needs be included in the lz4libs folder and also mentioned in the package meta data, right?

Does the license text from lz4 source files itself also need to be included as it is not exactly the same text as in the above license file, e.g.
https://github.com/lz4/lz4/blob/dev/lib/lz4.c ? Because it is not available in the wheels that contain the compiled binaries.
