Entitlement Check Implementation

Hey everyone
I ran into a wall here. I have my game finished and ready to publish (approved fine in Steam), but I'm trying to get it into Oculus Store, which means adding this entitlement check. The game was created in Unity 5.5 and I've imported Oculus Utilities 1.10 asset. I tried importing PlatformSDK asset previously, but no matter which I import into my project, I just get library compile errors that "ovr_*" does not exist in this context with no fixes suggested. 

I've tried looking at the documentation provided, but it's confusing af with tons of contradictions depending on the page looking at...
https://developer3.oculus.com/documentation/platform/latest/concepts/dg-cc-entitlements/
https://developer3.oculus.com/documentation/pcsdk/latest/concepts/dg-libovr/
https://developer3.oculus.com/documentation/platform/1.5/tasks/dg-cc-entitlements/ --unity link broken

Anyone know of a better tutorial...
Cheers
Will
