Eclipse挂载aws代码出现错误的原因？怎么解决？

硬件部分:esp32-s3 –wroom-1
软件部分: esp-idf-v4.4.2
开发环境:Wondows 7
IDE:  Eclipse IDE for C/C++ Developers Version: 2022-06 (4.24.0)

问题描述:
原本在keil c mdk 用AT command开发蛮顺手的，但后来转到IDF确让我挫折满满，编译后出现一堆问题，在网上没有找当我想找的答案，虚心求教一下

出现问题描述:
undefined reference to `app_main'
undefined reference to `app_main'
Symbol 'NULL' could not be resolved
Symbol 'ESP_ERR_NVS_NO_FREE_PAGES' could not be resolved
Symbol 'ESP_ERR_NVS_NEW_VERSION_FOUND' could not be resolved
esp-idf/freertos/libfreertos.a(port_common.c.obj): in function `main_task':

设定步骤
1.        开启idf 专案
2.        挂载 https://github.com/espressif/esp-aws-iot 项目内容(esp-aws-iot-masterexampleshttp)透过import -> file system 方式把*.c
        *.h挂载进来
3.        Cmakelist.txt不知道该如何修改
