Question

我使用cmake从MacOS的源代码构建了GLFW，一切顺利，示例正在运行。但是当我尝试使用clion中的cmake编译程序时，我收到以下错误：

Scanning dependencies of target triangle
[ 50%] Building CXX object CMakeFiles/triangle.dir/main.cpp.o
[100%] Linking CXX executable triangle
Undefined symbols for architecture x86_64:
  "_CFArrayAppendValue", referenced from:

    _matchCallback in libglfw3.a(cocoa_joystick.m.o)
  "_CFArrayCreateMutable", referenced from:
    __glfwInitJoysticksNS in libglfw3.a(cocoa_joystick.m.o)
    _matchCallback in libglfw3.a(cocoa_joystick.m.o)
... (There are a huge bunch of errors like this, let me know if you want to read all of them)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[3]: *** [triangle] Error 1
make[2]: *** [CMakeFiles/triangle.dir/all] Error 2
make[1]: *** [CMakeFiles/triangle.dir/rule] Error 2
make: *** [triangle] Error 2

我浏览了互联网和文档，发现我应该使用框架参数进行编译，如下所示：

cc -o myprog myprog.c -lglfw -framework Cocoa -framework OpenGL -framework IOKit -framework CoreVideo

我在命令行上尝试过它，它有效。但是，如果我想在CLion（或CMake？）中完成任务，或者我如何在CMake中使用框架呢？

我的CMakeLists.txt以防您想知道：

cmake_minimum_required(VERSION 3.8)
project(triangle)

set(CMAKE_CXX_STANDARD 11)
find_package(glfw3 REQUIRED)

set(SOURCE_FILES main.cpp)
add_executable(triangle ${SOURCE_FILES})
target_link_libraries(triangle glfw3)

我将此添加到我的CMakeLists.txt中，现在可以使用了：

cmake_minimum_required(VERSION 3.8)
project(triangle)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_FLAGS "-framework Cocoa -framework OpenGL -framework IOKit -framework CoreVideo")
find_package(glfw3 REQUIRED)

set(SOURCE_FILES main.cpp)
add_executable(triangle ${SOURCE_FILES})

target_link_libraries(triangle glfw3)

所以我的CMakeLists.txt看起来像这样：

 @Html.DropDownList("showTeams", null, "-Select Team-", htmlAttributes: new { id = "ddshowTeams", @class = "form-control" })
 @Html.DropDownList("showMembers", null, "-Select Team-", htmlAttributes: new {id = "ddshowMembers", @class = "form-control" })

我希望有一种更“优雅”的方式，但这现在解决了我的问题。
