  # This job tests the following things:
  # - Check if Release, MinSizeRel and RelWithDebInfo compiles correctly.
  # - Test the above build types with the GCC compiler specifically.
  #   Empirically the difference in warning levels between GCC and other
  #   compilers is particularly big.
  # - Test if the build works with multi-config generators. We mostly use
  #   single-config generators so it's nice to have a small sanity check for
  #   multi-config.
