Building on Windows

git clone https://github.com/microsoft/vcpkg
.\vcpkg\bootstrap-vcpkg.bat
.\vcpkg\bootstrap-vcpkg.bat
.\vcpkg\vcpkg install sdl2:x64-windows

Set -DCMAKE_TOOLCHAIN_FILE=C:\vcpkg\scripts\buildsystems\vcpkg.cmake

Ensure working directory is set so the obj/mtl files can be found.

Building on MVB Centos7

This project depends on C++17. However I later realised MVB machines do not support C++17

The ./mvb.sh script can be used to download and compile GCC 10 (without root) and then run this project
