Nginx add modules = how to? - nginx

Question

I just install Nginx on Oracle linux and working with it as reverse proxy.
it's wroking as I wanted.
now I want to add this moudle:
ngx_http_v2_module
how do I do this ?
where is the config file ?
everywhere I looked they say
his module is not built by default, it should be enabled with the --with-http_v2_module configuration parameter.
but I don't see any example of how to do it ....
when I enter
/usr/share/nginx/moudles/
I see this files only :
-rw-r--r--. 1 root root 65 Mar 30 2018 mod-http-geoip.conf
-rw-r--r--. 1 root root 72 Mar 30 2018 mod-http-image-filter.conf
-rw-r--r--. 1 root root 64 Mar 30 2018 mod-http-perl.conf
-rw-r--r--. 1 root root 71 Mar 30 2018 mod-http-xslt-filter.conf
-rw-r--r--. 1 root root 59 Mar 30 2018 mod-mail.conf
-rw-r--r--. 1 root root 61 Mar 30 2018 mod-stream.conf
so do I need to download something ? and put it in this directory ?
also
with this module I could push image to user?
meaning he will go the websites and will see my image\icon in his webpage?
or do I need another module ?
Thanks,

Assuming this is about Oracle Linux 7, Oracle provides nginx in two channels:
EPEL packages for Oracle Linux 7 (ol7_developer_EPEL)
# yum info nginx
Loaded plugins: langpacks, ulninfo
Installed Packages
Name : nginx
Arch : x86_64
Epoch : 1
Version : 1.12.2
Release : 2.el7
Size : 1.5 M
Repo : installed
From repo : ol7_developer_EPEL
Summary : A high performance web server and reverse proxy server
URL : http://nginx.org/
License : BSD
Description : Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 and
: IMAP protocols, with a strong focus on high concurrency, performance and low
: memory usage.
and it is compiled with the http2 module:
# /usr/sbin/nginx -V 2>&1 | sed -e 's/--with/\n\0/g' | grep http_v2
--with-http_v2_module
Alternatively there is also a version in the Software Collection Library (ol7_software_collections)
# yum info rh-nginx114
Loaded plugins: langpacks, ulninfo
Installed Packages
Name : rh-nginx114
Arch : x86_64
Version : 1.14
Release : 6.el7
Size : 0.0
Repo : installed
From repo : ol7_software_collections
Summary : Package that installs rh-nginx114
License : GPLv2+
Description : This is the main package for rh-nginx114 Software Collection.
where we also have support for http2:
# /opt/rh/rh-nginx114/root/usr/sbin/nginx -V 2>&1 | sed -e 's/--with/\n\0/g' | grep http_v2
--with-http_v2_module
So basically whatever version you have installed, you should be covered.
For the configuration of this module, you should look at the upstream NGINX documentation.
