Help with setting up libvirt for development.

Hi, pardon my ignorance. I'm trying to add some changes to the libvirt codebase (https://gitlab.com/libvirt/libvirt). I've successfully built it with `meson setup /build` and a `compile_commands.json` was generated in the build folder. But vscode keeps showing that there are errors from trying to find certain files and identifiers. I have also copied the `compile_commands.json` to the root of the project with no success. I'm new to working on a large C codebase, as i'm mainly into Go. I have also installed the `meson.build` extension as prescribed in https://mesonbuild.com/IDE-integration.html, is there anything i'm missing?
