So, I read that "SFML is completely free for any use, commercial or not, open-source or not. That is, you can use SFML API in your project without any restriction.". But what about libs which SFML uses(LGPL, BSD, GPL, FreeType License)?
Are these licences free for commercial projects(without share the sources)?
And what are the conditions for they?(give credit or join a license file)
