/**
 * To download NW.js binaries from a different place (for example, from live builds),
 * do the following:
 *
 * 1) Publish a customNwManifest.json with the needed version as its latest one.
 *    See https://nwjs.io/versions.json
 * 2) Set nwSource to the directory with a folder for this version.
 *    For example, if your binaries for each platform are at
 *    https://dl.nwjs.io/live-build/nw50/20201223-162000/6a3f52427/v0.50.3/,
 *    then you should specify the URL
 *    https://dl.nwjs.io/live-build/nw50/20201223-162000/6a3f52427/.
 * 3) Set nwVersion to `undefined` so that nw-builder loads the needed version from
 *    the created manifest and downloads it from a given source.
 *
 * For some reason, setting nwVersion to a specific version doesn't work, even with
 * a custom manifest.
 *
 * Also note that you may need to clear the `ct-js/cache` folder.
