qt 怎么才能不用cmake 就是用opencv

网上大多数都说 qt上用opencv  要cmake一下

但是好像也能不用cmake

试试

http://blog.youkuaiyun.com/homechao/article/details/8984706  根据这个文章 我的qt   pro配置文件 加上了 

（没改完 暂时这样）  （去掉了opencv_haartraining_engine.lib ）

（ debug版本  用的文件结尾都是d 结尾的）（qt应该是读取所有的LIBS文件 再运行程序 ，这也就是为什么少放lib文件 会加快速度）

（为什么要用vc12文件夹里面的内容，而不用vc10 vc11 我也不知道 ，就是这样试了一下   ）

实验成功！！！ 

但是不知为何   我总要 手动删除   build-untitled1-Desktop_Qt_5_6_0_MSVC2013_64bit-Release   之类的文件才能  重新运行程序

实验成功的最后的 配置文件  需要添加的 内容 如下
