title: Can I cross-build electron-forge apps for all platforms?
body: <p>I'm using electron-forge to build apps for Linux, macOS and Windows. Currently, I can build the macOS distributable natively from macOS, but I need two VMs to build for Linux and Windows.</p>
  <p>From each platform VM, I just need to issue the <code>make</code> script:</p>
  <p><code>npm run make</code></p>
  <p>Is it possible to cross-build for all platforms from a single system? Do I need one specific platform to be able to build for the others as well?</p>
  <p>What I want to accomplish is to be able to run a build script that will build distributable files for all supported platforms (namely Linux, macOS and Windows) from a single platform, without the need to manually run VMs.</p>
