opencv 3.0 编译

首先参考

http://www.07net01.com/2014/09/66490.html

进行初步编译

编译会报错：

CMake Error at 3rdparty/ippicv/downloader.cmake:97 (message):
  ICV: Failed to unpack ICV package from D:/Program
  Files/opencv/sources/3rdparty/ippicv/downloads/windows-b59f865d1ba16e8c84124e19d78eec57/ippicv_windows_20141027.zip
  to D:/Program Files/opencv/sources/3rdparty/ippicv/unpack with error 1
Call Stack (most recent call first):
  3rdparty/ippicv/downloader.cmake:108 (_icv_downloader)
  cmake/OpenCVFindIPP.cmake:212 (include)
  cmake/OpenCVFindLibsPerf.cmake:12 (include)
  CMakeLists.txt:454 (include)

解决方案：

自己下载ippicv最新版本，名字会不一样，复制到

\3rdparty\ippicv\downloads\windows-04e81ce5d0e329c3fbc606ae32cad44d，文件名不一样，hash不一样，该文件夹也会不一样

修改downloader.cmake中的文件名，

汇报hash错误，根据报错内容修改downloader.cmake中的hash内容，例子如下

    set(OPENCV_ICV_PACKAGE_NAME "ippicv_windows_20151201.zip")
    set(OPENCV_ICV_PACKAGE_HASH "04e81ce5d0e329c3fbc606ae32cad44d")
