Support for compile-commands.json / Automatic creation of a .clang file 
**Is your feature request related to a problem? Please describe.**
Syntax checking does apparently depend on a .clang file, but I don't know how to create one. So I need some tool to generate one for me. Cmake can already generate a compile-commands.json file, that might be useful here

**Describe the solution you'd like**
Add support for cmake's compile-commands.json or add a tool for automatic .clang creation

**Describe alternatives you've considered**
I have no clue how clang's flags work
