SFML CMake Linux question

[vidjogamer]

Why does it build 3 copies of each library? Are they different at all?

libsfml-audio.so        libsfml-graphics.so.2.0    libsfml-network.so.2.0.0  libsfml-window.so
libsfml-audio.so.2.0    libsfml-graphics.so.2.0.0  libsfml-system.so         libsfml-window.so.2.0
libsfml-audio.so.2.0.0  libsfml-network.so         libsfml-system.so.2.0     libsfml-window.so.2.0.0
libsfml-graphics.so     libsfml-network.so.2.0     libsfml-system.so.2.0.0

It's not 3 copies, the library is libsfml-xxx.so.2.0.0 and the 2 others are symbolic links that point to it. This is the standard way of handling libraries in Linux, so that you don't mess up with version numbers (your application links to libsfml-xxx.so, not libsfml-xxx.so.2.0.0).
