debhelper-compat-version 11 and systemd

[Tong Sun <pkgoyq.xpt@neverbox.com>]

Hi,

I have a d/rules file that uses systemd:

    rules:  dh $@ --with systemd

When setting debhelper-compat-version to 11 to fix the
“package-uses-old-debhelper-compat-version” problem, I got:

  dh: unable to load addon systemd: dh: The systemd-sequence is no
longer provided in compat >= 11, please rely on dh_installsystemd
instead
  Compilation failed in require at (eval 10) line 1.

I've searched for the solution but didn't find the answer.

How to fix it?

Thx
