How to use CLang in VSCode with PlatformIO [closed]

I am working on a project for esp32 board using Visual Studio Code with PlatformIO as an IDE (with Arduino framework) for code development.

I need to do static code analysis of my code and came to know that "CLang" can be used to serve the purpose. Please inform, do I need to require CLang to be installed externally or how to configure it with PlatformIO in VSCode for static code analyses.

I have followed below link but it says CLang is require if you use ATOM, but no information is available regarding how to use it with PlatformIO.
