Apologies, Mac builds were fixed for autotools make, but not for cmake. If you make the following change (additional line without leading +), this should fix your issue - please confirm as I do not have a Mac. I will raise a PR for it.

I suspect that you may need to add in to coap_io.c right at the beginning. Please confirm if this works.

Good that the coap_io.c (and potentially any following source files) compile is fixed, and only HAVE_IF_NAMETOINDEX is failing, I will try to see what that is failing when testing the get_nametoindex() function. No immediate ideas though.
@mrdeep1
The strange thing is that the following also doesn't work:
CMakeLists.txt
# check_function_exists(if_nametoindex HAVE_IF_NAMETOINDEX)
set(HAVE_IF_NAMETOINDEX 1)
https://cmake.org/cmake/help/latest/module/CheckFunctionExists.html
check_function_exists() only verifies linking, it does not verify that the function is declared in system headers.
Maybe none of the check_function_exists are set HAVE_*?
check_function_exists(malloc HAVE_MALLOC)
check_function_exists(memset HAVE_MEMSET)
check_function_exists(select HAVE_SELECT)
check_function_exists(socket HAVE_SOCKET)
check_function_exists(strcasecmp HAVE_STRCASECMP)
check_function_exists(pthread_mutex_lock HAVE_PTHREAD_MUTEX_LOCK)
check_function_exists(getaddrinfo HAVE_GETADDRINFO)
check_function_exists(strnlen HAVE_STRNLEN)
check_function_exists(strrchr HAVE_STRRCHR)
check_function_exists(getrandom HAVE_GETRANDOM)
check_function_exists(malloc HAVE_IF_NAMETOINDEX)
check_function_exists(if_nametoindex HAVE_IF_NAMETOINDEX)
We know that linking works, as you are able to build the code by commenting out the appropriate alternatove to if_nametoindex() code.
It certainly is possible that if_nametoindex is a #define. It is worth looking in build/CMakeFiles/CMakeError.log and build/CMakeFiles/CMakeOutput.log to see what is getting reported forif_nametoindexand, say malloc as a comparison.

That was a good catch, now it's working!

Now I think the last warning on OSX is:
-- Configuring done
CMake Warning (dev) at CMakeLists.txt:26 (add_library):

"cmake --help-policy CMP0115" for policy details. Use the cmake_policy
command to set the policy and suppress this warning.

The cmake on the Ubuntu20 system I am using is < 3.20 so not seeing this warning. However, there is a superflous line as per below that can be removed.

Tried to remove your suggestion:
${CMAKE_CURRENT_LIST_DIR}/include/coap${LIBCOAP_API_VERSION}/coap.h.in
But the warning is still there:
-- Configuring done

Line 26 is:
add_library(${COAP_LIBRARY_NAME})
I've upgraded to CMake version 3.21.1, same error as the version I was testing the other fixes.
I think the add_library() line eference is referring to all the definitions for the library and it is complaining about the file coap.h.in. As it is only a warning and not preventing compilation, I am unable to help further here as my version of cmake is < 3.20 which is when Policy CMP0115 was added to cmake.
The code changes to allow the macOS build have now been pushed into the develop branch under PR #731.
