[exim] How to cofigure exim config about spf

Hello, When I compiled exim, spf was enabled, and I used the libspf2 library. How can I configure spf in /etc/exim.conf, it is only setting CHECK_RCPT_SPF = true , and else ?

The exim config is below:
  .ifdef CHECK_RCPT_SPF
  deny
    message = [SPF] $sender_host_address is not allowed to send mail from \
              ${if def:sender_address_domain {$sender_address_domain}{$sender_helo_name}}.
    log_message = SPF check failed.
    !acl = acl_local_deny_exceptions
    condition = ${run{/usr/bin/spfquery.mail-spf-perl --ip \
                  ${quote:$sender_host_address} --identity \
                  ${if def:sender_address_domain \
                      {--scope mfrom  --identity ${quote:$sender_address}}\
                      {--scope helo --identity ${quote:$sender_helo_name}}}}\
                  {no}{${if eq {$runrc}{1}{yes}{no}}}}
  defer
    message = Temporary DNS error while checking SPF record.  Try again later.
    !acl = acl_local_deny_exceptions
    condition = ${if eq {$runrc}{5}{yes}{no}}

  warn
    condition = ${if <={$runrc}{6}{yes}{no}}
    add_header = Received-SPF: ${if eq {$runrc}{0}{pass}\
                                {${if eq {$runrc}{2}{softfail}\
                                {${if eq {$runrc}{3}{neutral}\
          {${if eq {$runrc}{4}{permerror}\
          {${if eq {$runrc}{6}{none}{error}}}}}}}}}\
        } client-ip=$sender_host_address; \
        ${if def:sender_address_domain \
          {envelope-from=${sender_address}; }{}}\
        helo=$sender_helo_name

  warn
    log_message = Unexpected error in SPF check.
    condition = ${if >{$runrc}{6}{yes}{no}}
  .endif

I find there is not exist about file which path is /usr/bin/spfquery.mail-spf-perl.
