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 only way to painlessly generate it is to use CMake.

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.

Method summary

Basically what we need to achieve is to create a CMake file that will generate a compile_commands.json file with information about:

	.Synopsis
	Parses html files produced by Google Takeout to present Google Voice call and text history in a useful way.
	.DESCRIPTION
	When exporting Google Voice data using the Google Takeout service, the data is delivered in the form
	of many individual .html files, one for each call (placed, received, or missed), each text message
	conversation, and each voicemail or recorded call. For heavy users of Google Voice, this could mean many
	thousands of individual files, all located in a single directory. This script parses all of the html
	files to collect details of each call or message and outputs them as an object which can then be
	manipulated further within powershell or exported to a file.

	///
	/// String(flag: "CH") // returns "🇨🇭"
	/// String(flag: "in") // returns "🇮🇳"
	/// String(flag: "eu") // returns "🇪🇺"
	/// String(flag: "42") // returns nil
