01. OpenGL环境搭建

windows下的环境搭建：
vs2022+vcpkg+cmake+glfw3+glad

1. Visual Studio 2022 community

2. vcpkg

> git clone https://github.com/microsoft/vcpkg
> cd vcpkg
> bootstrap-vcpkg.bat

3. vcpkg安装GLFW和GLAD

> vcpkg install glfw3:x64-windows
> vcpkg install glad:x64-windows
> vcpkg integrate install

安装后会显示

glfw3 provides CMake targets:

    # this is heuristically generated, and may not be correct
    find_package(glfw3 CONFIG REQUIRED)
    target_link_libraries(main PRIVATE glfw)

4. 创建cmake项目

目录结构

<project name>:
    CMakeLists.txt
    main.cpp

CMakeLists.txt
直接复制vcpkg安装glfw和glad后显示的文本

cmake_minimum_required(VERSION 3.12)

project(<project name>)

add_executable(main "main.cpp")

find_package(glfw3 CONFIG REQUIRED)
target_link_libraries(main PRIVATE glfw)

find_package(glad CONFIG REQUIRED)
target_link_libraries(main PRIVATE glad::glad)

main.cpp

#include <glad/glad.h>
#include <GLFW/glfw3.h>

int main()
{

    // OpenGL代码  

    return 0;
}

5. vs2022配置CMakeSettings.json

vs2022-项目- xxx的CMake设置
将CMake工具链文件改为 F:/vcpkg/scripts/buildsystems/vcpkg.cmake（vcpkg安装下F盘下）
即使用vcpkg integrate install命令后的显示

Applied user-wide integration for this vcpkg root.
CMake projects should use: "-DCMAKE_TOOLCHAIN_FILE=F:/vcpkg/scripts/buildsystems/vcpkg.cmake"
