Answer 1

CMAKE抱怨MD5哈希不匹配。

第3方的CMake警告/ ippicv / downloader.cmake：54（消息）：ICV：ICV包的本地副本具有无效的MD5哈希：d41d8cd98f00b204e9800998ecf8427e（预期： 8b449a536a2157bcad08a2b9f266828b）

由于the cmake file中提供的哈希值是正确的，这可能会告诉您下载的包已损坏。

Answer 2

再试一次：

 cmake \
 -DOPENCV_ICV_URL="http://downloads.sourceforge.net/project/opencvlibrary/3rdparty/ippicv"

Answer 3

您可以从以下链接下载ippicv_linux_20141027.tgz。并替换同 /home/akash/Downloads/opencv-3.0.0/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b/ippicv_linux_20141027.tgz
