I’m following the steps here https://pytorch.org/cppdocs/installing.html 8
My folder structure is as follows:

build/
libtorch/
CmakeLists.txt
example-app.cpp

The latter files are as described in the link. build is empty and for the libtorch folder I downloaded the gpu version from the main download page.
When I run the following command inside the build folder:
cmake -DCMAKE_PREFIX_PATH=../libtorch ..

I get the following message:
-- Caffe2: CUDA detected: 10.1

  Some of these libraries may not be found correctly.

I am a complete noob with Linux and c++/cmake. I have looked far and wide but cannot find out how to solve this. I don’t understand enough what information I should provide for help but here’s what I know.
Nvidia-smi and nvcc --version tell me I have CUDA 11.1 and driver version 455.23.05. My LD_LIBRARY_PATH is:
/usr/local/cuda-11.1/lib64. 

My PATH is:
usr/local/cuda-11.1/bin:/home/joe/anaconda3/bin:/home/joe/bin:/home/joe/.local/bin:/home/joe/anaconda3/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

I installed Pytorch 1.6 with Anaconda if that matters.
I am out of ideas on how to fix this. Any help is welcome!
