CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
EGL_LIBRARY
    linked by target “Common” in directory /home/null/opengles3/opengles3-book-master/Common
OPENGLES3_LIBRARY
    linked by target “Common” in directory /home/null/opengles3/opengles3-book-master/Common
— Configuring incomplete, errors occurred!
See also “/home/null/opengles3/opengles3-book-master/build/CMakeFiles/CMakeOutput.log”.
运行：ccmake ../



enter 进入编辑。
找到
/opt/Imagination/PowerVR_Graphics/PowerVR_SDK/SDK_4.0/Builds/Linux/x86_64/Lib/libEGL.so
/opt/Imagination/PowerVR_Graphics/PowerVR_SDK/SDK_4.0/Builds/Linux/x86_64/Lib/libGLESv2.so



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：
null@dev:~/opengles3/opengles3-book-master/build$ cmake ../

准备运行Hello_Triangle。

段错误 (核心已转储)
设置环境变量也没有解决。
null@dev:~/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$ export LD_LIBRARY_PATH=/opt/Imagination/PowerVR_Graphics/PowerVR_SDK/SDK_4.0/Builds/Linux/x86_64/Lib/
段错误 (核心已转储) 解决办法：

  Linux默认给一个进程分配的栈空间大小为8M。c++申请变量时，new操作申请的变量在堆中，其他变量一般在存储在栈中。因此如果数组开的过大变会出现这种问题。可以用指令ulimit -s XXXX来申请更大的栈空间。

null@dev:/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$
ulimit -a

null@dev:/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$ ulimit -s  102400
null@dev:/opengles3/opengles3-book-master/build/Chapter_2/Hello_Triangle$ sudo ./Hello_Triangle
