cmake doesn't figure out CURL_SA_FAMILY_T - build causes warnings

[bagder]

I did this

built curl with cmake on macOS

It cases warnings like:

/Users/runner/work/curl/curl/lib/curl_addrinfo.c:329:26: warning: conversion from 'short unsigned int' to 'sa_family_t' {aka 'unsigned char'} may change value [-Wconversion]
  329 |       addr->sin_family = (CURL_SA_FAMILY_T)(he->h_addrtype);
      |                          ^
/Users/runner/work/curl/curl/lib/curl_addrinfo.c:338:28: warning: conversion from 'short unsigned int' to 'sa_family_t' {aka 'unsigned char'} may change value [-Wconversion]
  338 |       addr6->sin6_family = (CURL_SA_FAMILY_T)(he->h_addrtype);
      |                            ^

... because the cmake build doesn't detect CURL_SA_FAMILY_T properly. configure does.

I expected the following

No warnings

curl/libcurl version

curl 7.76.1 and current curl git master

operating system

macOS but probably also elsewhere
