Difficulty with building on windows

[xtk923]

I had no problem building Triangle on linux/unix, but always encounter errors on windows.
I have tried with VC++ 2015, 2017 and 2019 and found no luck. Could you provide the version of VC++ you have used to build this package on windows?

No luck for me either. I tried to install VC++ from https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads, and it failed at building the package:

Did you guys manage to solve this? I'm facing the same problem.

It should be VC++ 2013 ( %VS120COMNTOOLS% ) the microsoft common build tools.
