What is your native language? Just wanted to know in case we go ahead and translate the tutorial into more languages in the future.
I think it is more or less clear from the tutorial that you should select one link type, either static or dynamic, not both. Obviously, you should only define SFML_STATIC if you choose to link statically. It doesn't make sense to define SFML_STATIC if you link dynamically does it? Also, there is no more SFML_DYNAMIC, not for the last 3 years. Not defining SFML_STATIC implies dynamic linking. Whoever suggests defining SFML_DYNAMIC to solve issues just resorted to trial and error rather than trying to understand and systematically solve the problem.
