Python 3.6 is not supported

[ardeal]

Hi,

If I build caffe(https://github.com/BVLC/caffe) on windows 10 64 bit, there is error.
Here are my settings:
Python 3.6.8
Visual Studio 15 2017 Win64
the following code in the cmake file(https://github.com/BVLC/caffe/blob/windows/cmake/WindowsDownloadPrebuiltDependencies.cmake) shows that Python3.6 is not supported.

Could you tell me how to add Python3.6 support?
