# Extra cmake flags. GitHub Actions matrix overloads `include` to mean
# 'add extra things to a job' and 'add jobs'. You can add extra things
# to a job by specifying things that exist in a job created from the
# matrix definition and adding things. You can specify extra jobs by
# specifying properties that don't match existing jobs. We use
# `cmake-flags` to add cmake flags to all jobs matching a pattern and
# `extra-cmake-flags` to specify a new job with custom CMake flags.
#
# Note that adding new jobs does not *refine* existing matrix entries,
# but rather adds new tuples wholesale. That is, specifying "os" alone
# will result in a tuple without set "build-type" rather than one for
# each existing "build-type" value!
