You also need to assign the cfg_CACHE_EFFECTIVE_USER variable a value

The following should work:

cfg_CACHE_EFFECTIVE_USER="nobody"
AC_ARG_WITH(cache-user,
[ --with-cache-user=USER System user account for squid permissions.
                          default: nobody],
[
    cfg_CACHE_EFFECTIVE_USER="$withval"
])
AC_SUBST(cfg_CACHE_EFFECTIVE_USER)

You don't need AC_DEFINE. AC_DEFINE adds a C macro definition.
