courier-webadmin package does not install all required dependencies

[Stephan]

Fresh install on Ubuntu 18.04.1 LTS,
courier-webadmin:
  Installed: 0.78.0-2ubuntu2

courierwebadmin fails to execute, logs list the problem:

Can't locate CGI.pm in @INC (you may need to install the CGI module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.26.1 /usr/local/share/perl/5.26.1 /usr/lib/x86_64-linux-gnu/perl5/5.26 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.26 /usr/share/perl/5.26 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at /usr/share/courier/webadmin/webadmin.pl line 6.
BEGIN failed--compilation aborted at /usr/share/courier/webadmin/webadmin.pl line 6.

manually installing the required module fixes the problem.

sudo apt-get install libcgi-pm-perl

I suggest to add this dependency to the package.
