编译OpenCV3.3.1 +contrib+vs2013+x86版本
一、准备工具
分别下载opencv3.3.1，opencv-contrib，cmake。默认已经安装VS2013。
opencv3.3.1下载地址 选择 win pack ，下载后会得到opencv-3.3.1-vc14.exe这样一个文件。
opencv-contrib下载地址 下载后得到opencv_contrib-3.3.1.zip这样一个文件。
camke下载 下载后得到cmake-3.10.1-win64-x64.zip的文件，在bin目录下的cmake-gui.exe 可直接打开运行。
二、cmake编译
1、打开刚刚下载的cmake，bin目录下的 cmake-gui.exe文件。
2、cmake第一行输入的是opencv的源码即opencv的source文件，第二行是编译好的文件放置处即mybulid文件夹。
3、第一次编译按Generate，设置选项 Visual Studio 12 2013（如果想编译成X64的opencv，此处选择 Visual Studio 12 2013 Win 64即可），成功后有done的标志。
4、在配置表中找到“OPENCV_EXTRA_MODUALS_PATH”，设置其参数值为opencv_contrib源码包中的modules目录。本次编译去除勾选WITH_CUDA选项。
5、再按下configure.成功后显示configuring done。可能会有红色的框条出现，再重复一次configure，更新后红色消除。
6、最后按[Generate]生成工程，如果配置和生成工程完全ok底下应该有Configuring done和Generating done两行。
三、打开opencv.sln工程，进行编译
1、打开刚刚保存目录下的 opencv.sln文件
2、在解决方案资源管理器中，选择“解决方案 opencv”->右键->重新生成解决方案。
3、找到CMakeTargets下的INSTALL,右键INSTALL->仅用于项目->仅生成INSTALL。
4、注意debug和release都编译一遍。
四、编程成功后，得到42个dll（你会感谢我的）
