    build: Don't use globbing to find sources
    
    Previously we were using a script to grab our sources
    automatically. However, this was error-prone and meson
    didn't actually understand the output.
    
    Now we declare our sources manually. This helps meson
    know when to trigger a build based on what files have
    changed.
