Why can't CMAKE find my SFML libraries in CLion? - c++

Question

I am trying to run SFML on CLion with CMAKE, and I keep getting the following error:
Error:Could NOT find SFML (missing: SFML_SYSTEM_LIBRARY
SFML_WINDOW_LIBRARY SFML_GRAPHICS_LIBRARY SFML_NETWORK_LIBRARY
SFML_AUDIO_LIBRARY)
This is my CMakeLists.txt file:
cmake_minimum_required(VERSION 2.6)
if(NOT CMAKE_BUILD_TYPE)
set(CMAKE_BUILD_TYPE Debug CACHE STRING "Choose the type of build (Debug or Release)" FORCE)
endif()
project(Polymorphism)
set(SOURCE_FILES main.cpp)
add_executable(Polymorphism ${SOURCE_FILES})
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/Modules" ${CMAKE_MODULE_PATH})
find_package(SFML REQUIRED system window graphics network audio)
if(SFML_FOUND)
include_directories(${SFML_INCLUDE_DIR})
target_link_libraries(${main.cpp} ${SFML_LIBRARIES})
endif()
Any help?

Answer 1

Impossible to tell, since we don't know your environment.
However, this should usually help:
Add a new CMake variable SFML_ROOT and let it point to the directory where SFML is installed.
Just add the variable to your CMakeCache.txt or pass it the first time you run CMake, e.g.:
cmake -DSFML_ROOT=/code/SFML path/to/source
Also you've got a problem further down below:
target_link_libraries(${main.cpp} ${SFML_LIBRARIES})
The first parameter is supposed to be the target, in your case Polymorphism. Also you should add SFML_DEPENDENCIES just in case someone tries to link SFML statically. In the end this line should look like this:
target_link_libraries(Polymorphism ${SFML_LIBRARIES} ${SFML_DEPENDENCIES})
