#
# This is a bit complicated for two reasons:
# - we really want to run dnf/apt/... only once, updating on the test runner for
#   each job takes forever. So we create a container image for each distribution
#   tested, then run the tests on this container image.
#
#   Creating a container image is time-consuming, so we only do so for pushes to
#   libinput directly (not merge requests) and if the current image is 'old'.
#
# - GitLab only allows one script: set per job but we have a bunch of commands
#   we need to re-run for each build (meson && ninja && etc). YAML cannot merge
#   arrays templates so we're screwed.
#
#   So instead we use a default_build template and override everything with
#   variables. The only two variables that matter:
#     MESON_ARGS=-Denable-something=true
#     NINJA_ARGS=dist ... to run 'ninja -C builddir dist'
#   Note that you cannot use scripts: in any target if you expect default_build
#   to work.
#
#
# All jobs must follow the naming scheme of
# <distribution>:<version>@activity:
#  e.g. fedora:29@build-default
