Disable avahi causes build to fail

[zarniwhoop73]

My only printer is an old epson inkject which is locally via usb.

According to configure, '--disable-avahi' allows builds without avahi.

** build details **
configure:

Environment settings:
CFLAGS: -g -O2 -Wall -std=gnu11 -D_GNU_SOURCE
CXXFLAGS: -Wall -D_GNU_SOURCE
LDFLAGS:
Build configuration:
cups-config: system
init directory:
cups dom socket: /run/cups/cups.sock
avahi: no
browsing: dnssd cups
local queue naming for remote CUPS queues: DNS-SD
keep generated queues during shutdown: no
update network interfaces after each found entry: yes
all ipp printer auto-setup: yes
only driverless auto-setup: no
only local auto-setup: no
werror: no

'make' then fails with:
gcc -DHAVE_CONFIG_H -I. -I/usr/include/cupsfilters -I/usr/include/ppd -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libmount -I/usr/include/blkid -pthread -I/usr/include/gio-unix-2.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libmount -I/usr/include/blkid -pthread -g -O2 -Wall -std=gnu11 -D_GNU_SOURCE -MT daemon/cups_browsed-cups-browsed.o -MD -MP -MF daemon/.deps/cups_browsed-cups-browsed.Tpo -c -o daemon/cups_browsed-cups-browsed.o test -f 'daemon/cups-browsed.c' || echo './'daemon/cups-browsed.c

daemon/cups-browsed.c:411:9: error: unknown type name 'AvahiAddress'
411 | const AvahiAddress *address;

(etc)

Expected behavior
Build succeeds without avahi.

System Information:

• OS: LinuxFromScratch
• Version 20221113

Additional context
Since I lack a networked printer, installing avahi would be an unnecessary vulnerability.
