  # The completions were removed because of problems with system bash

  # The `with-qt` GUI option was removed due to circular dependencies if
  # CMake is built with Qt support and Qt is built with MySQL support as MySQL uses CMake.
  # For the GUI application please instead use `brew install --cask cmake`.
