Cannot package UE4 project: "ovr_PopMessage already defined"

I’m trying to package a project in UE4, and it’s throwing the following error during the build process:

UE4-OnlineSubsystemOculus-Win64-Shipping.lib(Module.OnlineSubsystemOculus.cpp.obj) : error LNK2005: ovr_PopMessage already defined in LibOVRPlatform64_1.lib(LibOVRPlatform64_1.dll)

Everything works fine in the editor, it just won’t package.

Why is there a conflict between OnlineSubsystemOculus and LibOVRPlatform…? Aren’t these both Oculus libraries?

I have tried doing totally clean rebuilds of the project and the issue persists.

Anyone know what’s going on here?
