Eclipse IDE+IDF- 蓝牙例程“A2DP_Source"编译错误：undefined reference to..."

[yangrf@jmu.edu.cn]

大家好，最近因为需要选择蓝牙音频例程a2dp_source作为基本模板做开发，但是第一步就卡住了。
在eclipse IDE中导入例程，编译的时候出错，很多undefined reference to 错误
我想说的是我编译很多其他例程都没问题，比如hello world，所以编译环境应该是没问题的。
然后例程的文件都是通过cmake进行整合的，cmake我不太懂，而且牵连很广，大致看了下也看不出问题。
我换了vscode，结果是一样的，也是这种错误。（之前是64个错误，但我idf+ide装卸很多遍+python独立安装，现在的错误是44个），
快崩溃了，大佬救命！编译结果如下：谢谢！

哈咯，
能提供例程目录下CMakeLists.txt的截图吗？

[ESP_YTGerd]

另外编译之前可以检查下A2DP的配置项是否打开:
1) 在例程目录下终端输入: idf.py menuconfig
2) 路径: Component config->Bluetooth->Bluedroid Options->Calssic Bluetooth->A2DP
3) 将A2DP选上.
