The Bear Factory (i.e. the editors for the Bear Engine) requires wiWidgets < 3. Changes in the API of wxWidgets broke some parts of the editors.

If you are not interested by the editors, please pass the -DBEAR_EDITORS_ENABLED=0 argument to CMake.

Thanks, disabling the bear editor was the solution.
