LOADING A TORCHSCRIPT CMakeLists build error!

Hi guys. I follow the tutorial below.

https://pytorch.org/tutorials/advanced/cpp_export.html

I download libtorch/ and below is my CMakeLists.txt

cmake_minimum_required(VERSION 3.0 FATAL_ERROR)
project(custom_ops)

find_package(Torch REQUIRED)

add_executable(example-app example-app.cpp)
target_link_libraries(example-app "${TORCH_LIBRARIES}")
set_property(TARGET example-app PROPERTY CXX_STANDARD 14)

during cmake build I got an error below

pytorch_TorchScript/
 ㄴlibtorch/
 ㄴ build/
 ㄴexample-app.cpp

$ cd build
$ cmake -DCMAKE_PREFIX_PATH='/home/dhpark/pytorch_TorchScript/libtorch' ..

Error)

  Could NOT find Torch (missing: TORCH_LIBRARY)

I think the reason of the problem is
’ static library c10_LIBRARY-NOTFOUND not found.’

I don’t know how to solve it.

Can anyone help ??

Thanks alot.

It seems that cmake has trouble finding libtorch in your setup. Make sure the libtorch folder contains all expected files and maybe move it out of your project dir.
