编译opencv2 包含CUDA功能 -- 编译错误
最近项目需要，需要实现视频拼接的功能。网上搜了好长时间，基本思路是利用opencv 的video stitch模块，实现视频拼接。
下面我把编译opencv的过程写一下，过程比较曲折，现在把有歧义的部分记录一下。
我们需要用到的东西opencv3.2，CUDA, TBB。简单说一下这三者的作用，对比如下。
- OpenCV是一组编程模块，可帮助我们轻松完成复杂的实时计算机视觉任务。由于其可靠性和开源理念，它一直是最受欢迎的计算机视觉工具之一
- CUDA是一个并行计算工具包，它允许我们使用NVidia GPU的强大功能来显着提高应用程序的性能。
James Bowley发布了详细的性能比较，您可以在其中看到CUDA对OpenCV的影响(链接地址)
TBB是intel用标准c++写的一个开源的并行计算库。它的目的是提升数据并行计算的能力，可以在他的官网上下载最新的库和文档。TBB主要功能：
- 并行算法
- 任务调度
- 并行容器
- 同步原语
- 内存分配器
我安装的是CUDA10.2的版本，产生两个安装目录
C:\ProgramData\NVIDIA Corporation\CUDA Samples\v10.2
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2
opencv 有2.0、3.0d 的版本区分。CUDA也有很多版本，比如我安装的就是CUDA10.2。由于我的电脑比较旧，一直用的是vs2013的IDE。所以需要下载包含VC12的库。opencv 我使用的是3.2的版本，其实大版本还是属于opencv2。我知道的由于从CUDA9.0开始不再支持opencv2(某些写法调用会有变化，直接编译会导致失败。)会产生编译错误如下

搜了一下，找到了解决办法，附上链接解决编译错误。
