bear: add v3.1.4, bump deps, build the correct subdir

[valgur]

The root CMakeLists.txt only builds vendored dependencies and runs integration tests. Neither is useful for CCI. Switched to source/CMakeLists.txt instead.

• bear/3.0.21:
  Didn't run or was cancelled before finishing

---

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
