dependency_helper.sh

#!/bin/bash

# This is an debian dependency helper script for to help set up
# requirements for running make. Primarly this script is used by the CI,
# but is also useful when setting up a new env

# Before running it, you should export the desired PLATFORM environment
# variable ( one of pc, switch, 3ds, wii, wiiu, all )
#  eg. PLATFORM=switch ./dependency_helper.sh

# It may be easier to follow the README.md instructions for the
# desired target and platform that you want to build, but this script may
# help if you are interested in seeing how the dependencies come together
# on various platforms, or how the CI works
