Liaison SDL2 et Clion

Question

J'ai clion pointant vers les répertoires SDL2 et bibliothèques, mais il ne parvient pas à lier les bibliothèques lorsque je tente de construire. Des idées pour résoudre le problème?

CMakeLists:

cmake_minimum_required(VERSION 3.3) 

project(cavestory_development) 

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wall -Werror -lSDL2") 

set(SDL2_INCLUDE_DIR C:/SDL2-2.0.3/i686-w64-mingw32/include/SDL2) 

set(SDL2_LIBRARY C:/SDL2-2.0.3/i686-w64-mingw32/lib) 

find_package(SDL2 REQUIRED) 

include_directories(${SDL2_INCLUDE_DIR}) 

set(SOURCE_FILES main.cpp) 

add_executable(cavestory_development ${SOURCE_FILES}) 

target_link_libraries(cavestory_development ${SDL2_LIBRARY})

Voici un exemple minimal pour vous aider à démarrer avec SDL2 sur les fenêtres (main.cpp contient juste le SDL bonjour de LazyFoo)

cmake_minimum_required(VERSION 3.0) 
project(hello_sdl2) 

# configure the SDL (cf. "SDL2-2.0.3\i686-w64-mingw32\lib\pkgconfig\sdl2.pc") 
# C++ flags 
set(SDL2_Flags "-mwindows -Wl,--no-undefined -static-libgcc") 
# library paths 
set(SDL2_ROOT  "D:/PATH/TO/SDL2-2.0.3/i686-w64-mingw32") 
set(SDL2_Includes "${SDL2_ROOT}/include") 
set(SDL2_LibDir "${SDL2_ROOT}/lib") 
# imported targets for CMake (cf. https://cmake.org/Wiki/CMake/Tutorials/Exporting_and_Importing_Targets) 
add_library(SDL2  STATIC IMPORTED) 
add_library(SDL2main STATIC IMPORTED) 
set_property(TARGET SDL2  PROPERTY IMPORTED_LOCATION "${SDL2_LibDir}/libSDL2.a") 
set_property(TARGET SDL2main PROPERTY IMPORTED_LOCATION "${SDL2_LibDir}/libSDL2main.a") 
# the libs to link against 
# note: as always with gcc, the order is important... 
set(SDL2_Libs mingw32 SDL2 SDL2main m dinput8 dxguid dxerr8 user32 gdi32 winmm imm32 ole32 oleaut32 shell32 version uuid) 

# configure the project 
# include the SDL flags 
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 ${SDL2_Flags}") 
# collect the sources 
set(SOURCE_FILES main.cpp) 
# define the target 
add_executable(hello_sdl2 ${SOURCE_FILES}) 
# include the SDL headers 
target_include_directories(hello_sdl2 SYSTEM PRIVATE ${SDL2_Includes}) 
# link against the SDL (and its dependencies) 
target_link_libraries(hello_sdl2 ${SDL2_Libs}) 

testé sur 64bits Win8.1 avec SDL2-2.0.3, MinGW-W64 i686-5.2.0-posix-dwarf-rt_v4-rev0 et CLion 1.2 EAP (build 142.5239.6)
