# This workflow has two job matrixes.
# They can be considered phases because the second matrix ("test")
# depends on the first ("dependencies").
#
# The first phase has a job in the matrix for each combination of
# variables that affects dependency ABI:
# platform, compiler, and configuration.
# It creates a GitHub artifact holding the Conan profile,
# and builds and caches binaries for all the dependencies.
# If an Artifactory remote is configured, they are cached there.
# If not, they are added to the GitHub artifact.
# GitHub's "cache" action has a size limit (10 GB) that is too small
# to hold the binaries if they are built locally.
# We must use the "{upload,download}-artifact" actions instead.
#
# The second phase has a job in the matrix for each test configuration.
# It installs dependency binaries from the cache, whichever was used,
# and builds and tests rippled.
