我计划在windows操作系统上使用noevim。我主要使用cpp和安装msys64来获得gcc/g++编译器，gcc工具链位于C:\msys64\mingw64\bin目录下。我将相关路径添加到path变量中。我写了一个简单的你好世界：
```
#include <iostream>
int main (int argc, char *argv[])
{
std::cout << "hello cruel world" << std::endl;
return 0;
}
```
lsp clangd已成功附加到缓冲区，但出现错误"找不到iostream"。lsp.log如下，带有"-log=verbose"选项：
```

我尝试过的包括：
- 通过cmake工具生成compile_commands.json，失败
- 添加CPP_INCLUDE_*系统变量，失败
- 我使用.crangd文件配置项目，失败我想主要的问题是clangd找不到include路径，但我找不到解决方案。等待中，朋友们，帮帮我
在Windows上，clangd经常需要使用--query-driver选项才能正常工作。
请参阅https://clangd.llvm.org/troubleshooting#cant-有关更多详细信息，请查找标准库头映射stdioh等。
注意，--query-driver需要与compile_commands.json一起使用，并且--query-driver的参数应与compile_commands.json中命令开头出现的编译器可执行文件的完整路径匹配。
