I'm attempting to build OpenCV from source, using Visual Studio 2015 and Windows 7. But I've run into a problem. CMake is unable to extract 3rdparty/ippicv. The error is as follows:
ICV: Removing previous unpacked package: E:/opencv/source/3rdparty/ippicv/unpack

I am using source downloaded directly from the web yesterday. I have attempted this both on this machine (Windows 7 with Visual Studio 2015) and another (Windows 8.1 with Visual Studio 2010). Manually extracting the zip file to /unpack doesn't work either; CMake deletes the previous unpacked package.
