Need cmake option to disable Integration with Avahi mDNS

[dranch]

Per Rich WA3WLH,

I just built 1.7a on x86_86 Bullseye and upon testing noted the start up messages about integration with avahi. Unlike the comment block at the top of dns_sd_avahi.c my preference is no integration with avahi. I did not see an option in the Makefile to prevent integration with avahi and am not familiar enough with cmake to determine if there is an option there. I also did not see a command line nor a runtime config option.

Per WB2OSZ for a current work around:

There is currently no option to disable this (at this time). The easiest way would be to edit CMakeLists.txt and remove -DUSE_AVAHI_CLIENT from this line:

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -DUSE_AVAHI_CLIENT")
