How to use clangd C/C++ LSP in any project

tl;dr: If you want to just know the method, skip to How to section

Clangd is a state-of-the-art C/C++ LSP that can be used in every popular text editors like Neovim, Emacs or VS Code. Even CLion uses clangd under the hood. Unfortunately, clangd requires compile_commands.json to work, and the easiest way to painlessly generate it is to use CMake.

For simple projects you can try to use Bear - it will capture compile commands and generate compile_commands.json. Although I could never make it work in big projects with custom or complicated build systems.

But what if I tell you you can quickly hack your way around that, and generate compile_commands.json for any project, no matter how compilcated? I have used that way at work for years, originaly because I used CLion which supported only CMake projects - but now I use that method succesfully with clangd and Neovim.

	You are an assistant that engages in extremely thorough, self-questioning reasoning. Your approach mirrors human stream-of-consciousness thinking, characterized by continuous exploration, self-doubt, and iterative analysis.

	## Core Principles

	1. EXPLORATION OVER CONCLUSION
	- Never rush to conclusions
	- Keep exploring until a solution emerges naturally from the evidence
	- If uncertain, continue reasoning indefinitely
	- Question every assumption and inference

	# Generate the private and public keys
	openssl ecparam -name secp256k1 -genkey -noout \| openssl ec -text -noout > key

	# Extract the public key and remove the EC prefix 0x04
	cat key \| grep pub -A 5 \| tail -n +2 \| tr -d '\n[:space:]:' \| sed 's/^04//' > pub

	# Extract the private key and remove the leading zero byte
	cat key \| grep priv -A 3 \| tail -n +2 \| tr -d '\n[:space:]:' \| sed 's/^00//' > priv

	# Generate the hash and take the address part

	return {
	"stevearc/conform.nvim",
	event = { "BufReadPre", "BufNewFile", "BufEnter" },
	config = function()
	local conform = require("conform")

	-- Global variable to store the current formatter
	vim.g.current_formatter = "None"

	local formatters_by_ft = {
