How to solve libpng function already defined error?

Question

I am using ITK-4.11 and OpenCV-3.2 together in one of my C ++ projects, when I compile the project I get the error:

Error 1 LNK2005 error: png_get_uint_31 is already defined in itkpng-4.11.lib (pngrutil.obj) "

Both my ITK and OpenCV are built using a multi-threaded DLL (/ MD), what should I do to avoid this error?

If I remember correctly, I solved this exact problem by using the / FORCE linker option. More details here .
