Network, audio and system external dependencies

[netrick]

I want to edit SFML a bit and make my own version with network-audio-system module only. One reason is size of the library, second is just learning and the most important one is getting rid of annoying GLEW and freetype mit-styles licenses (well, they aren't annoying but I just prefer using only zlib type libraries ). In my current project I use 3d engine for graphics and SFML is being used only for network, audio and threading. But well code is a bit complicated and I'd like to be 100% sure before, what are dependencies needed for compiling sfml  network, audio and system module? Of course I will remove graphic and window module files.

Thanks

If you want to use SFML's audio module and only use zlib licenses then you've already lost, because SFML uses OpenAL and libsndfile which are both LGPL.
A list of possible dependencies can be found here or here.

Thanks for the links. AFAIK in LGPL libraries you don't need to mention anything if you link it without any changes, or I have to include the library's LGPL license too? So bad, it's so messed up with all those licences At first I thought that while using SFML I just need to put "this game uses sfml" in credits xD

EDIT:
Does anyone know a C++ audio library under zlib license? Probably there isn't one I guess

If there was, SFML would use it.

But what's wrong with these licences? You just need one file that lists the external libraries, the licence they use and a link to their full text.
