Hi Peter,

You need to link against the OpenSlide import library, which is distributed
in openslide-win64-20150527\lib\libopenslide.lib.  To do this, add it to
your project's library list in Project > [project] Properties > Linker >

Also, at runtime, the OpenSlide DLL and all of its dependencies (in
openslide-win64-20150527\bin) must be in the DLL search path.

The openslide-3.4.1 download is only the OpenSlide source code.  The
openslide-win64-* bundle includes the OpenSlide binary plus all of its
dependencies, and is much easier to use.
