ESP32-C3官方示例modbus-master，编译时提示找不到这两个头文件"modbus_params.h"和"mbcontroller.h"

E:/H3/mb_master/main/master.c:10:10: fatal error: mbcontroller.h: No such file or directory
10 | #include "mbcontroller.h"
| ^~~~~~~~~~~~~~~~
compilation terminated.

c_cpp_properties.json文件内容如下
{
"configurations": [
{
"name": "ESP-IDF",
"compilerPath": "E:\\esp\\.espressif\\tools\\xtensa-esp32-elf\\esp-12.2.0_20230208\\xtensa-esp32-elf\\bin\\xtensa-esp32-elf-gcc.exe",
"includePath": [

"${workspaceFolder}"
],
"limitSymbolsToIncludedHeaders": false
}
}
],
"version": 4
}

CMakeLists.txt文件内容如下：
set(PROJECT_NAME "modbus_master")

idf_component_register(SRCS "master.c"
INCLUDE_DIRS ".")
target_compile_options(${COMPONENT_LIB} PRIVATE "-Wno-format")


ESP-IDF版本5.1.1
请问是哪里配置有问题？如何找到这两个头文件？谢谢
