> 背景是这样的：最近闲着报了个深圳人社的 c 语言培训班。 完了之后想要把之前自己写的 python 图片处理脚本用 C 写一遍。 然后就发现没法引用第三方库(也许是自己哪里做错了)。
## 想要达成的目的
1. 在 vscode 中使用第三方库；
2. 了解我的 .vscode 里面的配置文件是不是哪里写错了？
## 当前情况及无法解决的问题(已 google 和 gpt)
以使用第三方库 **fmt** 为例，按照下述操作之后，在测试文件 ``` test.c``` 里面输入 ``` #include <f``` vscode 能自动联想出```#include <fmt/format.h> ``` ，但是在 debug 或 run without debug 时终端会报错以下内容 ：
#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (C:\Users\xxx\Desktop\C\test.c).
cannot open source file "cmath" (dependency of "C:\Users\xxx\.vscode\extensions\ms-vscode.cpptools-1.20.5-win32-x64\bin\fmt\format.h"). Please run the 'Select IntelliSense Configuration...' command to locate your system headers.
fmt/format.h: No such file or directory
## 已经进行的操作
1. gcc/gdb 都已经正常安装并且可以在终端正常使用；
其中，gcc 路径为：C:\MinGW\bin\gcc.exe ; gdb 版本为 GNU gdb (GDB) 7.6.1 ；
2. 包管理用的是 vcpkg;
安装到包的路径是：C:\vcpkg\installed\x64-windows\include
3. vscode 装了插件：C/C++ v1.20.5
4. 在 google 操作之后下来，之后相关文件内容如下：
