Added option to Cmake build allowing a custom location of zlib to be specified in a scenario where libpng is being built as a subproject alongside zlib by another project (Sam Serrels). Changed png_ptr->options from a png_byte to png_uint_32, to accomodate up to 16 options.

Configure libpng with "configure --enable-intel-sse" or compile libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it.
