How to make clangd recognize gcc header files under macOS

Question

I'm trying to use vscode-clangd plugin to complete my code. I've tried to use--query-driver and other parameters. Neither of them can recognize g+++ 12's header file properly, but clions that are also clangd based can recognize gcc's header file properly. Is this a bug? How should I fix it?

I tried to open the same CMake project with two compilers. These are their differences

This is the header directory given by vscode. screenshot

I tried to use - I fallback arguments to specify the directory of the header file, but clangd will give many error prompts.

"clangd.fallbackFlags": [

        "-I/usr/local/Cellar/gcc/12.2.0/include/c++/12/x86_64-apple-darwin22"
    ],

And I searched for similar problems on google, and I didn't find.
