Some progress but got stuck again here:

I've similar problem, but in building Torch for ppc64 architecture. But in the end it fails also to find the same set of libraries. I've CUDA 9.2, but in the log below you can see confusing output from the auto-detection. I read somewhere that this high CUDA is not supported. Have @spiralswimmer you tried to downgrade your CUDA already?

```Updating manifest for /root/torch/install/lib/luarocks/rocks

@spiralswimmer For the CUDA_cublas_device_LIBRARY NOTFOUND issue, pls refer to: https://github.com/torch/cutorch/issues/834 ;
@ahtonen I solved these NOTFOUND issues by set LD_LIBRARY_PATH=/use/local/cuda-9.2/lib64, and also make sure the lib64 directory has libcublas.so, libcurand.so, libcusparse.so files on AMD64 architecture.
