c++ - 如何使用 cmake 在 OSX 上编译 glfw

Question

我正在使用 jetbrains 的 CLion IDE 来编译一个小型的 hello world 应用程序。

这是我在尝试编译时得到的命令和错误的完整日志:

/Applications/CLion.app/Contents/bin/cmake/bin/cmake --build /Users/brian/Library/Caches/CLion12/cmake/generated/ac340afb/ac340afb/Debug --target Dunjun -- -j 4

我意识到要防止这些错误，我必须向编译器添加标志。其他 stackoverflow 问题将此引用为正确的命令:

gcc -Iglfw3/include/ -Lglfw3/lib/ -lglfw3 -framework OpenGL -framework Cocoa -framework IOKit -framework CoreVideo main.c

我如何通过 Cmake 执行此操作？我怎样才能让它在 CLion 下工作。

下面是我的 CmakeLists.txt 供引用:

cmake_minimum_required(VERSION 3.3)
project(Dunjun)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -framework Cocoa -framework OpenGL -framework IOKit")
SET( CMAKE_EXE_LINKER_FLAGS  "${CMAKE_EXE_LINKER_FLAGS}" )

set(SOURCE_FILES
    bin/Debug/Dunjun_game
    include/Dunjun/Common.hpp
    src/main.cpp
    CMakeLists.txt
    README.md)

add_executable(Dunjun ${SOURCE_FILES})
include_directories(include)

Answer 1

将 -framework 标志添加到链接器标志，而不是编译标志。

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -framework Cocoa -framework OpenGL -framework IOKit")
