macOS CLion 上搭建 GLFW + GLAD OpenGL开发环境

1. 构建并安装GLFW

下载GLFW源码 GLFW官网
构建并安装GLFW

# 切换至下载解压后的GLFW源码目录
cd glfw-3.3.6
# 创建 build 文件夹，用于存放配置和编译后的文件
mkdir build
# 切换至 build 目录
cd build
# 用 cmake 生成相关构建文件（请确保你的 Mac 已经安装了 CommandLineTool 和 CMake）
# 如果安装 CMake 后执行下方命令后依旧出现 “zsh: command not found: cmake” ，请先执行下面这条命令后重试
# sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install
cmake ..
# 构建并安装GLFW
make && sudo make install

2. 下载GLAD

进入 GLAD在线服务

3. 配置 CLion 项目

1.创建新项目

添加GLAD相关文件

# 1.在项目根目录下创建 include 文件夹
# 2.将下载下来的 GLAD源码 中的 include/KHR 和 include/glad 文件夹拷贝进项目中的 include 文件夹
# 3.将 GLAD源码 中的 src/glad.c 拷贝进项目根目录下（与 main.cpp 处于同一目录下！！！）

配置项目 CMakeList.txt

# 配置 CMake 版本（一般CLion会在创建项目时自动配置此选项，这里可以无需和笔者一致，默认即可）
cmake_minimum_required(VERSION 3.19)
# 生成项目（默认即可）
project(LearnOpenGL)
# 配置C++版本（默认即可）
set(CMAKE_CXX_STANDARD 14)# 头文件路径配置
include_directories(./include) # 这里的路径指向项目目录下的 include 文件夹
include_directories(/usr/local/include) # 此处的路径指向的是系统安装GLFW头文件的位置，通常为通过 make install 安装的头文件为此路径# 设置库文件所在目录
link_directories(/usr/local/lib) # 安装GLFW时默认安装库文件位置
# 链接编译需要的系统框架
link_libraries("-framework Cocoa -framework OpenGL -framework IOKit -framework CoreVideo")
# 添加源文件（这里的 main.cpp 是你的C++源码文件）
add_executable(LearnOpenGL glad.c main.cpp) # glad.c 一定要填进去！
# 链接 GLFW 库
target_link_libraries(LearnOpenGL glfw3)

4.测试环境

这里测试 LearnOpenGL 的三角形 Example

#include <glad/glad.h>
#include <GLFW/glfw3.h>#include <iostream>void framebuffer_size_callback(GLFWwindow* window, int width, int height);
void processInput(GLFWwindow *window);// settings
const unsigned int SCR_WIDTH = 800;
const unsigned int SCR_HEIGHT = 600;const char *vertexShaderSource = "#version 330 core\n""layout (location = 0) in vec3 aPos;\n""void main()\n""{\n""   gl_Position = vec4(aPos.x, aPos.y, aPos.z, 1.0);\n""}\0";
const char *fragmentShaderSource = "#version 330 core\n""out vec4 FragColor;\n""void main()\n""{\n""   FragColor = vec4(1.0f, 0.5f, 0.2f, 1.0f);\n""}\n\0";int main()
