How to compile Nginx with zlib-ng

[Sergey A. Osokin]

Hi Lance,

thanks for your question.

Since this is more or less related to nginx development or
new features I'd suggest to use nginx-devel mailing list
instead, thank you.

NGINX builds well with zlib.  In case of new functionality, like
an ability to build with zlib-ng, the source code requires some
patches.

Some ideas can be found inside the zlib-ng project on GH, not
sure is that working solution or not, so you can try.

I'd also recommend to raise a request in https://trac.nginx.org/nginx/
about this feature request and provide patches for source code
and documentation.

Thank you.
