	# This is a basic workflow to help you get started with Actions

	name: Build

	# Controls when the action will run. Triggers the workflow on push or pull request
	# events but only for the master branch
	on:
	push:
	branches: [ master ]
	pull_request:
	branches: [ master ]

	# A workflow run is made up of one or more jobs that can run sequentially or in parallel
	jobs:
	# This workflow contains a single job called "build"
	build:
	# The type of runner that the job will run on
	runs-on: ubuntu-latest

	# Steps represent a sequence of tasks that will be executed as part of the job
	steps:
	# Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
	- uses: actions/checkout@v4

	# We don't want to build openmpi each time this workflow is
	# run. Setup caching of OpenMPI after it is built and installed.
	# See "Caching dependencies to speed up workflows" on the GH
	# actions docs.
