CMake can not find SFML lib

Question

I have a project depends on SFML lib on C++. I trying to make it with CMake. CMakeLists.txt is:

cmake_minimum_required(VERSION 3.16.3)
project(3D_Renderer_from_scratch)

set(CMAKE_CXX_STANDARD 17)

include_directories(headers source)

set(SFML_STATIC_LIBRARIES TRUE)

find_package(SFML COMPONENTS window graphics system)

set(SOURCES
        Main.cpp
        source/Application.cpp
        source/Box.cpp
        source/Camera.cpp
        source/FileReader.cpp
        source/KeyboardHandler.cpp
        source/Sphere.cpp
        source/Triangle.cpp
        source/Window.cpp
        source/World.cpp
        )

add_executable(executable ${SOURCES})

target_link_libraries(executable ${SFML_LIBRARIES} ${SFML_DEPENDENCIES})

After running cmake . I have the following error:

$ cmake .
-- Requested SFML configuration (Static) was not found
CMake Warning at CMakeLists.txt:10 (find_package):
  Found package configuration file:

    /usr/lib/x86_64-linux-gnu/cmake/SFML/SFMLConfig.cmake

  but it set SFML_FOUND to FALSE so package "SFML" is considered to be NOT
  FOUND.


-- Configuring done
-- Generating done
-- Build files have been written to: /home/mcjohn974/3D_Renderer_from_scratch

How can I fix it ? (sfml lib is already installed)

Answer 1

As already mentioned in the comments (why not write it as an answer?), CMake was looking for static SFML libraries and it most likely just found shared libraries.

Either make sure that static libraries (the ones with the -s suffix) are provided.
Or don't request static libraries, which you can achieve be not setting SFML_STATIC_LIBRARIES.
