If you'd like to avoid all of these issues, I would recommend using the Manticore web app, which allows you to use SDL Core through your web browser.

Otherwise, it would appear that your error is related to log4cxx not being installed properly on your system. You can see the known dependency issues section of the SDL Core README for more details. The gist is that you may have to remove an existing log4cxx on your system before attempting to cmake your SDL Core.
