Hi all
I have problem while building using libtorch.
I tried to solve this problem myself, But i couldn’t solve toe problem for a long time,
so i wrote a post to get hlep.
I using Linux(centos7) CUDA 10 version libtorch zip.
https://pytorch.org/cppdocs/installing.html 1
I tried to check whether the example code was executed by following the link above.
But, cmake -DCMAKE_PREFIX_PATH=/absolute/path/to/libtorch .. command error occur.
Below is the error message.

-- Could NOT find CUDA (missing: CUDA_INCLUDE_DIRS CUDA_CUDART_LIBRARY) (found version "10.2")

  or a Caffe2 dependent library, the next warning / error will give you more
  info.

nvcc -V result is
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Wed_Oct_23_19:24:38_PDT_2019
Cuda compilation tools, release 10.2, V10.2.89

and echo $CUDA_HOME result is
/usr/local/cuda
I made a lot of effort to solve the problem myself, but I couldn’t solve it, so I posted it with desperate heart.
If you have solved this problem or know how to do it, please let me know.
Thanks.
Yours sincerely,
