问题描述：安装OpenVino后运行Demo时CMake出错
When I try to run the demo, during the inference engine build, I get an error related to cmake
I installed cmake on windows. I have windows 10 OS and VS 2015. Kindly advice how I can get rid of this error and make progress
"c:\Intel\computer_vision_sdk_2018.1.249\deployment_tools\demo\\..\inference_engine\samples\build"

解决方案：
原因可能有两种，
一是VS2015安装不完整，没有安装windows SDK，需要更新安装；
二是VS2015默认的开发语言不是C++，需要重设下。
重设方法为：工具---导入和导出设置---重置所有设置---“否，仅重置设置”---选择自己喜欢的开发环境
