Thank you handmade hero for making it easier to compile stuff

build.bat

@echo off

REM adds cl.exe to path
call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Auxiliary\Build\vcvarsall.bat" x64

REM Set current dir to folder of this script
pushd %~dp0

REM Then create and cd into build folder
mkdir build
pushd build

REM /I - additional include directories
REM /c - compile without linking
REM /EHsc - Exception handling model. sc - compiler will assume functions declared as extern C never throw C++ exceptions
cl.exe /I ..\include /c /EHsc ..\common\*.cpp

lib.exe /OUT:lxsdk.lib *.obj

REM cd .. to the original folder
popd
