| # 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! | |
