I’m working on building a lightweight version of Chromium. I want to exclude unnecessary dependencies, such as the support for iOS, Android, ChromeOS, Chromecast, etc.

What steps should I take to modify the underlying code to identify and remove what I do not want?

So far, I have a working build of the browser. I’ve tried configuring gclient as so;

    { "name"        : 'src',
      "url"         : 'https://chromium.googlesource.com/chromium/src.git',
      "deps_file"   : 'DEPS',
      "managed"     : False,
      "custom_deps" : {
          "src/third_party/catapult": None,
          "src/third_party/devtools-frontend": None,
          "src/third_party/ffmpeg": None,
          "src/third_party/libjingle": None,
          "src/third_party/widevine": None,
          "src/chrome/android": None,
          "src/ios": None,
          "src/chromeos": None,
          "src/components/cast_channel": None,
      },
      "custom_vars": {},
    },
]```
