- go to ext folder and extract sfml-zip
- create build directory "build" parallel to src
- open command line (win+r "cmd")
- navigate to the just created build folder
- type "cmake ../"
- For x86, use the win32 zip from the sfml website and use "cmake -A Win32 ../"
For mac os you have to install cmake and sfml via homebrew: brew install cmake sfml
If you use another package manager or want to install the dependencies yourself, you have to modify the paths in CMakeLists.txt
