Dockerfile

# This Dockerfile uses multi-stage building to minimize size
# while maintaining all necessary dependencies. The build
# stage brings in dependencies necessary for building setsm
# and then compiles the source code. The run stage brings the
# executable created from the build stage into a new image and
# includes required dependencies

# Command Line arguments

ARG COMPILER=gnu
