OpenCV2学习笔记02：MSVC2013搭建OpenCV开发环境

我这里编译的库是通过手动编译的。只是需要注意的是，手动编译一般会产生大量的文件，差不多7个多G的样子，实在是有点浪费硬盘存储呀，其实我们可以删除掉没有用的东西。因为我们在编译的时候指定了一个目录比如我设定的/build/vs2013，所有的文件都会在vs2013文件夹下生成，而唯一对我们有用的就是最终生成的install文件夹，除了这个文件夹的内容之外，其他的文件可以全部删除。去掉那些无用的文件之后，磁盘瞬间轻松了许多，有图有真相。

1. 首先设置系统的环境变量：

D:\3rdPartLib\opencv-2.4.\build\vs2013\install\x64\vc12\bin

2. 指定“可执行文件目录”，不区分Debug和Release模式：

D:\3rdPartLib\opencv-2.4.\build\vs2013\install\x64\vc12\bin

3. 指定包含“文件目录”路径，不区分Debug和Release模式：

D:\3rdPartLib\opencv-2.4.\build\vs2013\install\include

4. 指定“库目录”，Debug和Release模式设置相同：

D:\3rdPartLib\opencv-2.4.\build\vs2013\install\x64\vc12\lib

5. 比较麻烦的就是添加“附加依赖项”了，

Debug模式下的依赖项：

opencv_videostab249d.lib;
opencv_video249d.lib;
opencv_ts249d.lib;
opencv_superres249d.lib;
opencv_stitching249d.lib;
opencv_photo249d.lib;
opencv_ocl249d.lib;
opencv_objdetect249d.lib;
opencv_nonfree249d.lib;
opencv_ml249d.lib;
opencv_legacy249d.lib;
opencv_imgproc249d.lib;
opencv_highgui249d.lib;
opencv_gpu249d.lib;
opencv_flann249d.lib;
opencv_features2d249d.lib;
opencv_core249d.lib;
opencv_contrib249d.lib;
opencv_calib3d249d.lib;

而Release模式与Debug模式的区别是库文件后面少了一个符号"d"，如下：

opencv_videostab249.lib;
opencv_video249.lib;
opencv_ts249.lib;
opencv_superres249.lib;
opencv_stitching249.lib;
opencv_photo249.lib;
opencv_ocl249.lib;
opencv_objdetect249.lib;
opencv_nonfree249.lib;
opencv_ml249.lib;
opencv_legacy249.lib;
opencv_imgproc249.lib;
opencv_highgui249.lib;
opencv_gpu249.lib;
opencv_flann249.lib;
opencv_features2d249.lib;
opencv_core249.lib;
opencv_contrib249.lib;
opencv_calib3d249.lib;

注意：如果在编译过程中修改了以上这些参数，请一定要重新启动开发环境，否则可能报错。
