查看ippicv的downloader.cmake文件中写明的版本是:ippicv_linux_20151201.tgz
download下来后丢到下面的路径上:
opencv-3.2.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e
808b791a6eac9ed78d32a7666804320e为该文件的md5sum
opencv_contrib-3.2.0/modules/dnn/.download/bd5e3eed635a8d32e2b99658633815ef/v3.1.0
同上,bd5e3eed635a8d32e2b99658633815ef为protobuf文件的md5sum
这个更麻烦些,直接把.download文件夹内容全部copy到opencv_contrib\modules\xfeatures2d\cmake.download
最终的参考tree格式:
C:\p\opencv_contrib\modules\xfeatures2d\cmake.download>tree /F
