You can set it in CMake by adding it to CMAKE_CXX_FLAGS (which works
better anyways since editing the .vcxproj files will be overridden by
CMake when it reruns).

Hrm. It's probably supposed to be `_WIN32` (which is the standard define
for detecting Windows). Could you open a bug? We have a VS 2015
buildbot, but it is Windows 7 (not that I think that's a big difference
for this problem) and it is building vtknetcdf (where it looks like that
file exists).
