Building obs studio on Windows

Building on windows is more difficult than on Linux To start with a recent build of obs-studio is best
The below build script is what I use in Jenkins,
It should be as simple as placing the below in a .bat, installing the required obs-studio dependencies and changing paths as required. See the obs-studio documentation for how to build it and required dependencies. This script builds using Visual Studio Expres 2013
set Arch to be x86 or x64
set BuildTarget to be Release or RelWithDebInfo
set WORKSPACE to be a location of checked out obs-studio

Setlocal EnableDelayedExpansion

echo %Arch%
echo %BuildTarget%

set OBSSTUDIOBUILD=R:\rundir\%TARGETBUILD%\obs-studio
