Possibly :)

That was indeed the direction I was thinking. You could give it a try,
especially if you already have installed all the things it needs via
ports/pkg.  It just might find them automatically. Apart from zlib then.
(extract the tar file, run configure, then run make or gmake).

Otherwise, you have to "fight" with the extra level of indirection that
the ports system creates. Personally I'm used to pkgsrc on NetBSD. That
started out as a fork of FreeBSD's ports, but they have diverged quite a
bit. So I can give some hints on what to try, but that's about it, I
fear.

First, what value to use for those variables. You'd have to locate the
zlib header file zlib.h. For me it is in /usr/include/zlib.h. Then I'd
use

    ZLIB_CFLAGS=-I/usr/include

which would typically already be a default (so I guess for you it is
either installed elsewhere, or the configure script just wants to see
some value here so that it won't try to run pkg-config)

Similarly we need libz.so and (assuming it's in /usr/lib/libz.so)

    ZLIB_LIBS="-L/usr/lib -lz"

(yes the name of the library and the header file seem inconsistent...)

Now how to get those variables actually passed to the configure script.
Here we need some improvisation. Check if other ports Makefiles have
lines looking somewhat like the ones above; searching for -I and -L
might be enough. It could be as simple as (for pkgsrc)

    CONFIGURE_ENV+=          MAKE_FLAGS=-j${MAKE_JOBS:Q}

which looks like it would pass some value for MAKE_FLAGS on to the
configure stage. Once you identify how that works for ports (and there
might even be documentation in the FreeBSD Handbook about it; I didn't
check), simply adjust it it pass your ZLIB_CFLAGS=... and ZLIB_LIBS=...
.  Put that in the Makefile of the port. Then run the usual "make
install" for it.

Yes, the usual "ritual" is running configure; make; make install,
possibly with extra options and settings here and there for adjustments.
Sometimes the software is straight from its master repository and it
doesn't have a configure script generated. Then there is some step
before it to create it (usually autogen.sh or autoreconf).
