A DESCRIPTION OF THE PROBLEM :
The windows powershell build script "build.ps1" located in ".\tools\scripts" does not set the following environment variables:

* MSVC_REDIST_VER
* WINDOWS_CRT_VER

which results in builds not containing the correct dlls if the defaults for those settings in win.gradle aren't correct.

In addition there are other build dependencies which can be installed using chocolatey automatically, specifically:

* Cygwin
* Visual Studio 2017 Community
* Visual Studio 2017 workload for desktop development with c++
* Microsoft DirectShow header files



FREQUENCY : always
