How to work with latest Instant-NGP version ?

The latest version of Instant-NGP, doesn't have the build files as required by this project (such as ngp_shared.dll , ngp_shared.pdb ,pyngp.pdb etc). Is there a method where we can use the latest version ? I tried using the older commit versions of I-NGP repo, but to no avail. I would really like to know the approach to take here, to perform NeRF volume rendering in Unity.
