[osg-users] [build] Building from CMAKE on Windows - missing PNG_PNG_INCLUDE_DIR

[Andrew]

It's probably due to this 'code' in Find3rdpartyDependencies.cmake.

        IF(ZLIB_FOUND)
            FIND_DEPENDENCY(PNG png.h "libpng;libpng13" ${OSG_3RDPARTY_BIN} "D")
            IF(PNG_FOUND)
                #forcing subsequent FindPNG stuff to not search for other variables.... kind of a hack 
                SET(PNG_PNG_INCLUDE_DIR ${PNG_INCLUDE_DIR} CACHE FILEPATH "")
                MARK_AS_ADVANCED(PNG_PNG_INCLUDE_DIR)
            ENDIF(PNG_FOUND)
        ENDIF(ZLIB_FOUND)
