Research direction

Examine the existing logging mechanism in Sourcetrail's source code, e.g., see how logging is currently done in files like 'lib/logger/LogManager.h'. Look at the preferences system (possibly in 'lib/utility/Preferences.h') to understand how to add a new preference for log level. Check the CLI argument parsing code (e.g., 'src/main.cpp' or similar) to see how to add a new command line option. Review any existing discussions in the issue comments for implementation hints.
