Pigeonhole configure failure

Again same problem but in other way with Dovecot 2.3.20 and CloudLinux 7.9
Previous version 2.3.19 works fine and compile without error.
When I try to compile 2.3.20 then I get:

checking for "/usr/lib64/dovecot/dovecot-config"... not found
configure:
configure: Use --with-dovecot=DIR to provide the path to the dovecot-config file.
configure: error: dovecot-config not found
Trying to make pigeonhole 0.5.20
make: *** No targets specified and no makefile found. Stop.
*** The make has failed. Exiting...

Tested on two servers with CL 7.9
On CL 8.x everything is fine

Workaround is symlink /usr/lib/dovecot to /usr/lib64/dovecot this time.
