Native Unity DLL not loading

[cpaganucci]

I'm trying to use the Unity DLLs in the 0.9.3 Beta release, but I am getting this error in Unity 2019.2:

Plugins: Failed to load 'Assets/Plugins/openark_unity_0_9_3_native.dll' because one or more of its dependencies could not be loaded.
OpenARK.Detector:.ctor(Boolean)

And this error when I try it in 2017 or 2018:

DllNotFoundException: openark_unity_0_9_3_native

I have tried changing the API compatibility level, and have made sure that the DLLs are set to the correct platform.

I’m also having the same issue in Unity 2018.4.11f1 (LTS). @sxyu is there a particular version of Unity required?
