你需要安装cmake和库
sudo apt-get install libgles2-mesa-dev libvulkan-dev glslang-dev
还希望
sudo apt-get install libsdl2-dev libxt-dev libxaw7-dev doxygen
下载存档（因为我的 cmake ，我选择了相当旧的存档， ogre-1.12.13.zip ）
解压缩，使用控制台构建转到解压缩的文件夹并输入命令：
cd Home/ogre/ogre-1.12.13 mkdir build cd build cmake .. make sudo make install
我创建一个构建文件夹，调用一个 kumeik，然后构建它，然后进行安装。
之后，您可以运行最简单的示例（尽管我重新启动计算机以获得更高的可靠性）
