I am sure I am missing an environment variable somewhere or linking directive for cmake
I’m a bit confused, but did you make sure to download libtorch with the appropriate CUDA version?
E.g.
https://download.pytorch.org/libtorch/cu100/libtorch-shared-with-deps-latest.zip
Oh my god…
Thank you so much I noticed just now that in setup.py I had the wrong link to the wrong libtorch :X…
At least now I am getting the same error as you, BUT I am able to run it successfully on cuda so THANK YOU you good sir you saved my sanity! 
Haha, awesome!
Sorry for not checking it earlier, but I somehow missed this possibility completely.
