致命错误:GLES2 2/gl2.h:没有此类文件或目录

Question

我正在尝试在Urho3D 3上安装RPi。(GPU = 768 MB)

我安装了所有必要的依赖项。所有的台阶都很好。直到在最后的make步骤中发生此错误为止：

[ 56%] Building CXX object Source/Urho3D/CMakeFiles/Urho3D.dir/Graphics/Skybox.cpp.o

有什么建议吗？我该怎么办？

我在编译其他项目时也遇到了类似的错误。正如@steeldriver建议的那样，我通过安装库来解决这个问题：

sudo apt-get install libgles2-mesa-dev
