The lwip library is failing to build libpng, which it depends on. The error
mentions "see the notes in pngpriv.h". If you check the comments in that
source file
<https://github.com/EyalAr/lwip/blob/master/src/lib/png/pngpriv.h#L805>
they say this:
# error ZLIB_VERNUM != PNG_ZLIB_VERNUM \
"-I (include path) error: see the notes in pngpriv.h"
/* This means that when pnglibconf.h was built the copy of zlib.h that it
* used is not the same as the one being used here. Because the build of
* libpng makes decisions to use inflateInit2 and inflateReset2 based on
the
* zlib version number and because this affects handling of certain
broken
* PNG files the -I directives must match.
*
* The most likely explanation is that you passed a -I in CFLAGS. This
will
* not work; all the preprocessor directories and in particular all the
-I
* directives must be in CPPFLAGS.

Do you get this error when running 'npm install' and testing locally, or
does it only occur when running 'gcloud app deploy'?
