This affects our project as well. You can see it in the live here: https://code.launchpad.net/~otto/+recipe/mariadb-10.3-dev-daily

The error it hangs on:

**********
CMake Error at cmake/submodules.cmake:27 (MESSAGE):
  No MariaDB Connector/C! Run

      git submodule update --init

  Then restart the build.
