Linking with CMake

[jaqb17]

Hello!

I want to generate a simple project with CMake. Here is my CMakeLists.txt

Code: [Select]

cmake_minimum_required(VERSION 3.4)
 
project(Program)
 
set(SOURCE_FILES
        src/main.cpp
        )

set(SFML_ROOT "${CMAKE_SOURCE_DIR}/SFML/lib")
set(SFML_INCLUDE_DIR "${CMAKE_SOURCE_DIR}/SFML/include")
set(SFML_LIBRARY_DIR "${CMAKE_SOURCE_DIR}/SFML/lib")
 
 
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/SFML/cmake/Modules")
 
find_package(SFML 2 REQUIRED window )
 
include_directories(
    ${SFML_INCLUDE_DIR}
)
 
add_executable(Program ${SOURCE_FILES}
        ${SFML_LIBRARIES}     
)
 
message ( ${SFML_LIBRARIES} )
 
target_link_libraries(Program ${SFML_LIBRARIES})
Everything works great on OSX, but on Windows SFML_LIBRARIES looks like this:
debug<path...>/lib/libsfml-window-d.aoptimized<path...>/lib/libsfml-window.a


...and because of that i got CMake error (check out screenshot).
What should I do to make it work on Windows?

No, not because of that. This part is perfectly fine. What's wrong is that you put libraries in add_executable (which should only contain source files).

OK I removed SFML_LIBRARIES from add_executable, and generating works well, but now linking is a problem (undefined references).
I tried to build SFML by myself, and also modified my CMakeLists.txt. Now it looks like that:

Code: [Select]

cmake_minimum_required(VERSION 3.4)

project(Program)

set(SOURCE_FILES
        src/main.cpp
        )




set(SFML_ROOT "C:/Users/Komputer.DESKTOP-5G9R8AU/Desktop/SFML_ROOT/install")
set(SFML_INCLUDE_DIR "C:/Users/Komputer.DESKTOP-5G9R8AU/Desktop/SFML_ROOT/install/include")
set(SFML_LIBRARY_DIR "C:/Users/Komputer.DESKTOP-5G9R8AU/Desktop/SFML_ROOT/install/lib")



set(CMAKE_MODULE_PATH "C:/Users/Komputer.DESKTOP-5G9R8AU/Desktop/SFML_ROOT/install/cmake/Modules")


find_package(SFML 2 REQUIRED window)

include_directories(
    ${SFML_INCLUDE_DIR}
)

add_executable(Program ${SOURCE_FILES}

)

message ( ${SFML_LIBRARIES} )


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

Something I forgot?

The error messages

[jaqb17]

Here you go!
It throws error like this for every use of SFML object.

The window module depends on the system module, so you'll also have to find that. Additionally you shouldn't set SFML_INCLUDE_DIR and SFML_LIBRARY_DIR yourself, those are automatically set by FindSFML.cmake.

[jaqb17]

Oh shit! Right! I forgot about system module! Thanks sir! Now everything is fine.
