Examples:

cd /usr/ports/zsh/shells
$ make showconfig
===> The following configuration options are available for zsh-5.0.0:
     DEBUG=off: Install debug symbols
     DOCS=on: Build and install the documentation
     GDBM=off: Enable GDBM support (GPL)
     MAILDIR=on: Enable support for Maildirs in MAIL(PATH)
     MEM=off: Enable zsh-mem options
     MULTIBYTE=on: multibyte character support
     PCRE=off: Use Perl Compatible Regular Expressions
     SECURE_FREE=on: Enable zsh-secure-free
     STATIC=off: Build static executable/libraries
===> Use 'make config' to modify these settings

$ OPTIONS_SET="STATIC" make showconfig
===> The following configuration options are available for zsh-5.0.0:
     DEBUG=off: Install debug symbols
     DOCS=on: Build and install the documentation
     GDBM=off: Enable GDBM support (GPL)
     MAILDIR=on: Enable support for Maildirs in MAIL(PATH)
     MEM=off: Enable zsh-mem options

$ zsh_SET="STATIC" make showconfig

     GDBM=off: Enable GDBM support (GPL)

$ OPTIONS_OVERRIDE="STATIC" make showconfig

OPTIONS_SET and zsh_SET are the two normal way of setting options in make.conf.
OPTIONS_SET being global and zsh_SET being specific.

With both make sure to either not have them in make.conf of have them define with ?= or +=

Be careful that they can be changed by OPTIONS_UNSET and zsh_UNSET from make.conf if any

on the other hand OPTIONS_OVERRIDE will deactivate all options setting what ever the defaults are,
what the saved configuration can be etc.

and run the make command with just the options defined in it activated
