From: Heiko Hund <he...@ist.eigentlich.net> CMake has support to create a json file which contains exact information how each file in the project is compiled. This file can be consumed by clangd, which in turn provides precise symbol information to IDEs for better code navigation and contextual information.
I use it with vscode to be able to quickly switch between native Linux and mingw builds and have the symbols info change dynamically with it. So handy that I think it is useful for others as well. Bump required CMake version for CREATE_LINK.
