oh... now I remember. An automated way has been added sometime around
~VTK5.0, now vtkWin32VideoSource gets compiled automatically (while it
used to be an advanced option) when the result of a try compile is
positive:

...
  IF (VTK_VFW_SUPPORTS_CAPTURE)
    SET (Kit_SRCS ${Kit_SRCS} vtkWin32VideoSource.cxx)
  ENDIF (VTK_VFW_SUPPORTS_CAPTURE)
...

If you check CMake/vtkTestVideoForWindows.cmake, you'll see that only
the linker is being tested (not all required symbols/macros), thus
resulting in your issues.

the surprising part is that it works out of the box for the nightly dashboard:

Cool ! Added to:

http://vtk.org/Bug/view.php?id=635

I'd suggest you forward your email to the cygwin mailing list. Until
the try_compile test in VTK is fixed (open a bug report if you want).

Thanks & congrats !
