What is the Goal of the PR?

To enable build on Windows platform.

What is the Motivation for the PR?

I'm using Windows :) I'm new to community based development and js dev and github. I forked the repository and cloned it to my pc and followed instructions to build, but that failed. This should not happen. The project/repository should be platform independent.

What Tests are Included?

It builds
