Building Opus with Visual Studio 2015 fails

I cloned the latest sources (v1.1.3-140-g096b2207) from Opus git and tried building Opus with Visual Studio 2015 in Windows 7.

At one point I get this error which causes a failure: opus.lib(vq.obj) : error LNK2001: unresolved external symbol op_pvq_search_sse2
