There's both. The following repo is an example of interfacing with a licensed Widevine SDK: 
https://github.com/WebPlatformForEmbedded/OCDM-Widevine

For the library version of Widevine, both Firefox and Kodi are examples of how to use that.

https://github.com/WebPlatformForEmbedded/OCDM-Widevine is the glue code to a licensed Widevine SDK. From WebKit POV,
you'll  want to be looking at the derived CDMInstanceOpenCDM class in the WPEWebKit github account for guidance on how
WebKit connects to WPEFramework. WPEFramework in turn talks to the OCDM-Widevine plugin mentioned above.
