Issue with enabling LIBpng - Hardware Target NXP1776-evkb

is there any Github repository with Png.h and all other libraries for libpng is enabled . Currently when i enable libpng , iam getting errors as png.h is not available.
is Libpng faster than Lodepng , we have been using lodepng it seems to be slow for our use case , so we are exploring libpng
