  "message": "Refactor Ceres threading option configuration.\n\n- Previously we had separate variables for each of the threading\n  backends, each of which were made mutually exclusive via\n  cmake_dependent_option().  This has unfortunate side-effects when\n  trying to disable options if they are not currently enabled, in which\n  case they are not defined.\n- As all the threading options are mutually exclusive, this replaces\n  all threading option variables with a single variable: CERES_THREADS,\n  which is constrained to take the value of only the available threading\n  backends.\n\nChange-Id: I0822eefbac9a30772907b7732add365b37cc8ca0\n",
