Clion Cmake & SDL2

Question

Clion을 SDL2와 함께 사용하고 싶고 많은 테스트를 거친 후에 이미 오류가 있습니다.

내 CmakeLists.txt있다 :

cmake_minimum_required(VERSION 3.8) 
project(sdl2-test) 

#set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -lmingw32") 
#set(CMAKE_EXE_LINKER_FLAGS "-static-libgcc -static-libstdc++") 
set(CMAKE_CXX_STANDARD 11) 
include_directories(${PROJECT_SOURCE_DIR}/include) 
link_directories(${PROJECT_SOURCE_DIR}/lib) 

set(SOURCE_FILES main.cpp) 
add_executable(sdl2-test ${SOURCE_FILES}) 

target_link_libraries(sdl2-test SDL2main SDL2) 

내 MAIN.CPP

#include <iostream> 

#include "include/SDL2/SDL.h" 

using namespace std; 

int main(int argc, char** argv) { 
    if(SDL_Init(SDL_INIT_EVERYTHING) == -1){ 
     cout << "Something went wrong! " << SDL_GetError() << endl; 
    } 

    SDL_Window* window = SDL_CreateWindow("SDL_Demo", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 
             1280, 720, SDL_WINDOW_OPENGL); 
    if(window == nullptr){ 
     cout << "Something also went wrong here" << endl; 
    } 

    SDL_Delay(2000); 
    SDL_Quit(); 
    return 0; 

} 

하지만 난 내 프로젝트 cmake를 빌드 할 때 분명히 Cmake 작업은 찾을 수 있지만 몇 가지 오류 haave :

수정 방법은 무엇입니까?

Answer 1

링커가 sdl2-lib의 위치를 ​​알지 못하기 때문에 응용 프로그램 연결이 실패했습니다.

당신은 당신의 cmake 파일뿐만 아니라 SDL2-라이브러리를 검색하고 메이크에 위치를 추가해야합니다

find_file(SDL2_INCLUDE_DIR NAME SDL.h HINTS SDL2) 
find_library(SDL2_LIBRARY NAME SDL2) 
add_executable(ChickenShooter main.cpp) 
target_include_directories(ChickenShooter ${SDL2_INCLUDE_DIR}) 
target_link_libraries(ChickenShooter ${SDL2_LIBRARY}) 

당신은뿐만 아니라이 게시물에 볼 수
