如何在 MacOS 上的 clion 上为 glfw 正确设置 cmake

Question

I've recently bought a Macbook and I want to start writing some OpenGL code for a project.

SPECIFICATIONS

• MacOS
• Macbook pro 16inch 2019
• Clion
• glfw3 (precompiled binaries 64 bit)

The CMake doesn't complain, but as soon as I start compiling I get the following error

    /Applications/CLion.app/Contents/bin/cmake/mac/bin/cmake --build /Users/arnesix/Documents/dev/c++/graphics/cmake-build-debug --target graphics -- -j 12

  "_CFArraySortValues", referenced from:
      _matchCallback in libglfw3.a(cocoa_joystick.m.o)

The binaries I have downloaded from https://www.glfw.org/download.html only contain the 64 bit binaries.

I am using the following cmake code and folder structure

#include <iostream>
#include <glfw3.h>

int main() {
    std::cout << glfwInit() << std::endl;
    return 0;
}

and lastly, my Cmake preferences

I would love to know why this keeps happening and how I should resolve this issue.

Answer 1

Did you read the documentation ? You're missing three frameworks if you compile like that:

target_link_libraries(graphics glfw3 -framework Cocoa -framework OpenGL -framework IOKit)

Better to just use the find_package approach

Answer 2

I had exactly the same problem.
I'm using local (not system-wide) glfw with glad .
Here is my cmake file I've ended up with which worked for me.

cmake_minimum_required(VERSION 3.17)
project(project_name)

set(CMAKE_CXX_STANDARD 14)
if (APPLE)
    set(CMAKE_CXX_FLAGS "-framework Cocoa -framework IOKit")
    # -framework OpenGL -framework CoreVideo
    add_compile_definitions(GL_SILENCE_DEPRECATION)
endif ()

include_directories(<your include dir here>)
add_executable(project_name <your source files here>)

target_link_libraries(project_name <path to libglfw3.a>)

The line which actually helped me was set(CMAKE_CXX_FLAGS "-framework Cocoa -framework IOKit")

GL_SILENCE_DEPRECATION part seems to have no impact, so probably can be ignored.
