undefined reference to ...

[wrona]

Hello,
OS: Debian testing
SFML: 2.5.0+dfsg-2
Standard install way: sudo aptitude install libsfml-dev

I have a problem with my project after updating the SFML from 2.4.2 to 2.5.0 version .When I tried to compile it i get an error message::

[ 50%] Linking CXX executable LittleHero
CMakeFiles/LittleHero.dir/main.cpp.o: In function `main':
/home/wrona/Code/C++/RPG/LittleHero/main.cpp:9: undefined reference to `sf::String::String(char const*, std::locale const&)'
/home/wrona/Code/C++/RPG/LittleHero/main.cpp:9: undefined reference to `sf::VideoMode::VideoMode(unsigned int, unsigned int, unsigned int)'
/home/wrona/Code/C++/RPG/LittleHero/main.cpp:9: undefined reference to `sf::RenderWindow::RenderWindow(sf::VideoMode, sf::String const&, unsigned int, sf::ContextSettings const&)'
/home/wrona/Code/C++/RPG/LittleHero/main.cpp:9: undefined reference to `sf::RenderWindow::~RenderWindow()'

It's only simple skeleton of project:

Code: [Select]

cmake_minimum_required(VERSION 3.10)
project(LittleHero)

set(CMAKE_CXX_STANDARD 11)

add_executable(LittleHero main.cpp)

set(CMAKE_MODULE_PATH "/usr/share/SFML/cmake/Modules/" ${CMAKE_MODULE_PATH})
find_package(SFML 2.5 REQUIRED graphics window system)
if(SFML_FOUND)
    include_directories(${SFML_INCLUDE_DIR})
    target_link_libraries(LittleHero ${SFML_LIBRARIES} ${SFML_DEPENDENCIES})
endif()

Code: [Select]

#include <iostream>
#include <SFML/Graphics/RenderWindow.hpp>
#include <SFML/Window/Event.hpp>

using namespace std;

int main() {

    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML window");
    window.close();
    return 0;

}

You can remove the SET CMAKE_MODULE_PATH, remove the SFML ${} variables and remove the include directory directive.
Insteadyou need to list the librariesto link yourself, but you only need to specify the top dependencies (e.g. only sfml-graphics and no need for sfml-system).
