因为最近需要用到densflow提取光流，所以要安装opencv2.4.13结果各种错误和bug!
解决了这些问题，故而开始安装denseflow了，使用TSN来安装。
1、CMake Error: CUDA_nppi_LIBRARY (ADVANCED)

2、Error:CPACK_PACKAGE_VERSION does not match version provided by version.hpp header!

3、诸如“No package ‘gstreamer-base-1.0’ found”等，缺少众多依赖项

5、Perhaps you should add the directory containing `opencv.pc’
