I'm using Visual Studio 2015 Ultimate Preview and OpenCV 3.0 Alpha on windows 7 64bit. The project in VS is 32bit console application. I'm getting a linking error when I try to build a simple example just reading in an image in a Mat type. The errors are looking like:

1>opencv_core300d.lib(alloc.obj) : error LNK2038: mismatch detected for '_MSC_VER': value '1800' doesn't match value '1900' in solver.obj

1>opencv_core300d.lib(alloc.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in solver.obj

After Googleing the issue, I learned that I have to recompile the OpenCV library in order to be linked with my project.

How can I do that? I can't find a makefile in opencv to import in VS and recompile from there. what is the solution?

Thanks, this helps, but now I'm having trouble to rebuild with Cmake cuz ICV: Local copy of ICV package has invalid MD5 hash. It failed to download the ippcv automatically, and I don't know where to place after I downloaded the required version.

I have it in the following path:

opencv/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b/ippicv_linux_20141027.tgz

First, try to remove the downloads folder and run cmake again, it should download correct version. You can also build OpenCV without IPP: -DWITH_IPP=OFF
