Installing dynamic modules when Nginx itself is installed via yum/dnf (Linux)

Thank you Thomas. Much appreciate this, it sounds promising. Appreciate
your clarity.

So if I:

1. Compile nginx via `dnf install nginx` and that becomes my system's
Nginx, installed usually in `/etc/nginx`

2. In a totally separate folder, say, `/usr/src`, I then download a tarball
of Nginx and compile it along with the dynamic modules -- which will
produce the .so files for said modules

3. Copy over the modules into the usual `/etc/nginx/modules` folder from
Step 1 this sequence of steps, how do I make sure that:

A. The compilation in Step 2 does not become my "system's nginx" (so when I
do an `nginx -v` at the command prompt it should be refer to the nginx
installed in Step 1 above, and *not* the one compiled via Step 2)

B. The compile in Step 2 will use the "same libraries" that DNF used? In
the DNF version of life I didn't pick any libraries manually...DNF found
what was on my system. Will the manual compile not do the same?

Many thanks!
