I think the change is not that complex but brings much added value. About the
integration with the build system, there are many build systems out there so I
don't think better integration will be useful in many scenarios (plain make,
custom builds, etc). This solution is generic enough so that any build system
that generates compile_commands.json will be supported in a pretty good way.
