Ubuntu16.04 LINUX 下构建OpenGL ES 3.0
该开发环境是配合书籍《OpenGL ES3.0编程指南》来配置的。
软件：PowerVRSDKSetup-2018_R2.run-x64
下载地址：https://www.imgtec.com/developers/powervr-sdk-tools/installers/
操作系统：Ubuntu 16.04
adayo@ubuntu:/work/opengles3-book-master/build$ sudo ./PowerVRSDKSetup-2018_R2.run-x64
adayo@ubuntu:/work/opengles3-book-master/build$ sudo apt-get install build-essential cmake cmake-curses-gui
adayo@ubuntu:/work$ ls

adayo@ubuntu:/work/opengles3-book-master$ mkdir build
adayo@ubuntu:/work/opengles3-book-master$ cd build
adayo@ubuntu:/work/opengles3-book-master/build$ cmake ../
需要配置库文件路径：
adayo@ubuntu:/work/opengles3-book-master/build$ccmake ../
enter 进入编辑。
找到
/opt/Imagination/PowerVR_Graphics/PowerVR_Tools/PVRVFrame/Library/Linux_x86_64/libEGL.so
/opt/Imagination/PowerVR_Graphics/PowerVR_Tools/PVRVFrame/Library/Linux_x86_64/libGLESv2.so
这个两个路径非常重要，如果选择错误，编译出来的可执行程序运行时会发生段错误。
完成配置后按C保存，再按Q退出ccmake。
再执行cmake，生成makefile，然后执行make：
adayo@ubuntu:/work/opengles3-book-master/build$ cmake ../
adayo@ubuntu:/work/opengles3-book-master/build$ make
准备运行Hello_Triangle
adayo@ubuntu:/work/opengles3-book-master/build/Chapter_2$ cd Hello_Triangle/
adayo@ubuntu:/work/opengles3-book-master/build/Chapter_2/Hello_Triangle$ ls
CMakeFiles cmake_install.cmake Hello_Triangle Makefile
adayo@ubuntu:/work/opengles3-book-master/build/Chapter_2/Hello_Triangle$ ./Hello_Triangle
