Have you read the C++ tutorial?

I'm sorry but everything that you need is there, have a look at the documentation, tutorials and examples. If you have a specific question I'll be happy to answer you, but to learn the basics you'll need to read a little bit.

I understand that it is a shader and what it's for. I just can not understand how it works. Okay, but what is RenderStates and RenderTarget and what is it for?

Then read the corresponding tutorials, examples and documentation. They exist for a reason.

Again, check the API documentation.

I don't see any SFML dlls in this folder. You must have it copied at the same path which application is placed.
