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.
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 %Label%
echo %Arch%
echo %BuildTarget%

set TARGETBUILD=%BuildTarget%
set OBSSTUDIOBUILD=R:\rundir\%TARGETBUILD%\obs-studio
mkdir "%OBSSTUDIOBUILD%"
set OBSSTUDIOBUILD32=R:\Projects\obs-studio\build32\%TARGETBUILD%
set OBSSTUDIOBUILD64=R:\Projects\obs-studio\build64\%TARGETBUILD%
set OBSSOURCE=%WORKSPACE%
