Currently, if `PNG_FOUND`, cmake scripts will check include and parse header while we can use `PNG_VERSION_STRING` conveniently. If `BUILD_PNG`, parse version from `PNG_LIBPNG_VER_STRING` directly is more convenient than parsing major, minor and patch and concatenate them. The comment of png.h also supports this. ``` /* These should match the first 3 components of PNG_LIBPNG_VER_STRING: */ ``` https://github.com/glennrp/libpng/blob/libpng16/png.h#L287 This patch also modifies `ocv_parse_header_version` macro to receive another parameter to make it more general. The reason why changing `PNG_VERSION` to `PNG_VERSION_STRING` is to be consistent with cmake's FindPNG. This patch removes `HAVE_LIBPNG_PNG_H` variable because `PNG_INCLUDE_DIR` is where to find png.h, etc according to https://cmake.org/cmake/help/latest/module/FindPNG.html. This patch also removes `PNG_PNG_INCLUDE_DIR` variable which is an advanced variable used in cmake's FindPNG and is not used in opencv.
