How to apply c++ code after successful pytorch android build?

pytorch build for android was completed as follows.

$ ANDROID_NDK=.../android-ndk-r21e
$ ANDROID_ABI="arm64-v8a"
$ cd scripts
$ ./
... (long time) ...
[100%] Linking CXX static library ../lib/libtorch.a
[100%] Built target torch
Install the project...
-- Install configuration: "Release"
Installation completed, now you can copy the headers/libs from /mnt/HDD_2TB/greenfish/pytorch_build/work.trial9/pytorch/build_android/install to your Android project directory.

the install dir is as follows.

├── include
│   ├── ATen
│   ├── TH
│   ├── THCUNN
│   ├── c10
│   ├── caffe2
│   ├── fp16
│   ├── pybind11
│   └── torch
├── lib
└── share
    ├── ATen
    └── cmake

example code:

#include <torch/torch.h>
#include <iostream>

int main() {
  torch::Tensor tensor = torch::eye(3);
  std::cout << tensor << std::endl;

find_package(Torch REQUIRED)

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


src$ mkdir build
src$ cd build
build$ cmake ..

CMake Error at CMakeLists.txt:4 (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:


  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

Passing the CMAKE_MODULE_PATH and CMAKE_PREFIX_PATH values ​​did not work.
How can I pass the install directory?
