有没有办法在不重新编译的情况下指定clangd的c++标准？

Question

I'm trying to use a feature in c++17(const lambdas) without having clangd error me. I've searched online and every answer tells me to recompile clangd with a flag. Is there truly no other way?

Edit: Clangd is not the compiler. It's a language server, which is a program made to be used with IDEs that basically checks your code for errors and warnings before compiling it. See https://clangd.llvm.org .

Answer inspired by n. 1.8e9-where's-my-share m.

From https://clangd.llvm.org/config#compileflags :

You can create a config file for clangd. In the config file, you can specify the compiler options mimicked. For my question, do this:

CompileFlags:
  Add: [-std=c++20, -Wall]
