How to add libtorch library to CLION?

I am trying to get started with DeepLearning using libtorch, pytorch's C++ version on my Windows machine.

However, problems have been arising throughout the installation process: Namely, I cannot seem to find my libtorch-library inside clion.

The error message I get is:

CMake Error at CMakeLists.txt:6 (find_package):
  By not providing "FindTorch.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Torch", but
  CMake did not find one.

  Could not find a package configuration file provided by "Torch" with any of
  the following names:

    TorchConfig.cmake
    torch-config.cmake

  Add the installation prefix of "Torch" to CMAKE_PREFIX_PATH or set
  "Torch_DIR" to a directory containing one of the above files.  If "Torch"
  provides a separate development package or SDK, be sure it has been
  installed.

I am a little ashamed to even ask this question, because it looks like the error message is very descriptive, but I have been trying for a couple of hours now and cannot solve it. So far I have tried:

It looks like there is a very simple solution to this using cmake, however, I am fairly new to cmake, so I hope someone can help me in a way I can understand.

EDIT: Okay, I was able to fix it with all of your help, thank you guys and especially @drescherjm helping out my cmake-illiterate butt.

The error instructs you to

set "Torch_DIR" to a directory containing one of the above files`.

You can set one by passing it as a command line argument:
cmake .. -G Ninja -DTorch_DIR="path_to_your_local_torch_dir
Do NOT include your local paths within your CMakeLists.txt like the other answers suggest you to.

this is my CMakeLists.txt and it works:

cmake_minimum_required(VERSION 3.17)
project(libtorch_test)

set(CMAKE_CXX_STANDARD 14)
add_executable(libtorch_test main.cpp)

set(CMAKE_PREFIX_PATH /home/myhost/device/libtorch/share/cmake/Torch)

find_package( Torch REQUIRED )

key point for the issue is that set CMAKE_PREFIX_PATH as your/path//libtorch/share/cmake/Torch
