title: Weird linker error linking to opencv... "LNK1107: invalid or corrupt file: cannot read at 0x2E8"
body: <p>This OpenCV build was working for me a few nights ago.  I am trying to run the example <code>grabcut.cpp</code> file given with the OpenCV examples and so I set up a quick project and brough the <code>cpp</code> file in.  Then, I set up all of the standard configurations and got this error on building.</p>

  <p>What does this mean?</p>
