# Windows SRT Build Script
#============================
# Usable on a Windows PC with Powershell and Visual studio, 
# or called by CI systems like AppVeyor
#
# By default produces a VS2019 64-bit Release binary using C++11 threads, without
# encryption or unit tests enabled, but including test apps.
# Before enabling any encryption options, install OpenSSL or set VCKPG flag to build
