Now that I am using JNA this should be pretty easy and just involves getting the libfreenect DLLs as well as updating LibraryPath.java.
Kinect v2 working on windows on the branch vc2013, tomorrow I'll tested on a fresh pc and I'll merge to the master branch.
I did not have any issues with the LibraryPath.java on Windows, I just added the .libs and .dll inside the native library folder and everything links automatically.
I suggest adding three new folders inside the library folder; msvc, mac and linux
both v1 and v2 has windows support.
