I am working with visual basic 2013 , and I have managed to setup the sfml successfully ! but there is something I can't understand . when I debug my program these is no need for dll files . but when I run the exe file , it requires dll's ! I am using -d libraries , and SFML_STATIC , and every thing works fine . examples of sfml like pong , does not require dll's , so how can I do that?
