#[[
if(graphtest) 
set(SFML_DIR "${CMAKE_CURRENT_SOURCE_DIR}/include/SFML-2.5.1/lib/cmake/SFML")
find_package(SFML 2.5 COMPONENTS graphics audio REQUIRED)
add_executable(graphicTest src/graphic_test.cpp src/network.cpp src/random.cpp)
target_link_libraries(graphicTest sfml-graphics sfml-audio)
endif(graphtest)
