I suspect this has something to do with
#include <iostream.h>
vs.
#include <iostream>

googling gets me here:
http://www.itk.org/Wiki/ITK_Configuring_and_Building
which suggests
// The code still uses the older #include <iostream.h> style
CMAKE_CXX_FLAGS:STRING=-Wno-deprecated

but that's only a warning flag, it doesn't make my compiler find the
".h" files...
