使用node-gyp构建本机模块（尝试对我的cpp文件使用ffmpeg），它会引发异常：错误LNK2001无法解析的外部符号

示例代码：

index.cpp

    #include <node.h>
    extern "C"
    {
      #include "demo.h"
    }

demo.h

    int testFn();

demo.c

    int testFn(){
        return 0;
    }


binding.gyp

    {
      "targets": [
        {
          "target_name": "addon","sources": [
            "index.cpp"
          ],"include_dirs": [
            "<!@(node -p \"require('node-addon-api').include\")"

          ],"dependencies": [
            "<!(node -p \"require('node-addon-api').gyp\")"
          ]
        }
      ]
    }

构建错误信息

有人知道我在调用上述代码时可能做错了什么吗？ 谢谢。

ps： 我试图编辑binding.gyp文件（添加库项）

{
  "targets": [
    {
      "target_name": "addon","sources": [
        "hello.cpp"
      ],"libraries": [
         "D:/lib/ffmpeg-4.2.1-win64-dev/lib/**"
      ],"dependencies": [
        "<!(node -p \"require('node-addon-api').gyp\")"
      ]   
    }
  ],}

node-gyp构建正常，但无法正常运行，运行.js文件以要求本机模块异常错误：找不到指定的模块。
