[说明] 执行该脚本可获取Learning OpenGL配置完整工程代码

#!/bin/sh

# This script will download the dependencies for the Learning
# OpenGL repository and compiles the source code once the
# dependencies have been installed in the install directory. The
# install directory is `../install` relative to this file.
#
# This downloads and installs
#
# - glfw
# - glm
# - assimp
# - learning opengl
