本文以【STM32F103ZET6】单片机作为示例来进行演示，标准库/HAL库的工程是通用的，修改CMakeLists.txt里面的源文件和头文件引用部分即可。
更多细节请参考【VSCode编辑+GCC for ARM交叉编译工具链+Makefile构建+OpenOCD调试（基于STM32的标准库）】
下面列出几个主要的配置文件：
- settings.json
- c_cpp_properties.json
- tasks.json
- launch.json
- CMakeLists.txt
- ⭐ MCU链接脚本.ld、MCU汇编启动文件.s、MCU寄存器文件.svd请参考【VSCode编辑+GCC for ARM交叉编译工具链+Makefile构建+OpenOCD调试（基于STM32的标准库）】文章获取。

细节注意：如果读者将上述的CMakeLists.txt文件移植到自己的标准库/HAL库工程后，需要重新配置CMake相关的本地嵌入式工具链，否则会报错。参考方法的截图如下，
