Hi! At the top of the Build.cmd you include a call to:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\VsMSBuildCmd.bat
Unfortunately, I don't have that file. I'm guessing this has something to do with the VS2017 RC.3 that I'm using. I'll try to do a side-by-side 2015 install but you might want to update the code to work with the RC.
In either case, thanks for sharing your great work. Its much appreciated...
