花了一天时间终于大功告成了，主要事件都花在下载opencv的开源代码上了，虽然不大（也就80多M），但是网速炸啊。十几二十几K的下，开了vpn都没用，一样是龟速。言归正传
要准备三样东西，一个是QT的开源代码（注意是源码，不是什么安装包），一个是CMake，还有一个就是opencv啦。具体的链接自己去官网找吧。。。我用的是qt5.5.1，CMake最新版，opencv2.4.11（因为最新的opencv我编译的时候总是出错，只好用opencv2了）
首先要把QT装好，然后配置好环境变量Path，这也不细说。接下来安装CMake，注意勾选将XXX加入环境变量。装好CMake后就可以开始安装opencv啦。先把下好的opencv源码解压好，打开CMake，在源路径中填上源码的路径，在目标路径中填上你想安装的路径（最好是你要安装的位置，见一个build文件夹）不用源码安装的话，目录下最终会生成build，source文件夹，分别存放待编译的文件和源码。
点击configure，然后选WINGW Makefile 和下面第二个选项，然后c和c++的编译器要到QT的安装目录的mingw里面找。等待。然后勾上WITH_QT,WITH_OPENGL;在次点击configure（重要！）。然后generate；
进入cmd，找到相应目录，mingw32-make 漫长的等待。。。。 mingw32-make install
安装成功，接下来就是配置。
