JPEG2000 support not baked in

Description: Ubuntu 18.04.2 LTS
Release: 18.04
Package version: 1.0-3

This package is advertised as supporting JPEG2000 images. The output from 'apt-cache show iipimage-server' states "Source images can be in either TIFF or JPEG2000 format."

When attempting to serve a JP2 image, IIP Image Server logs the following to /var/log/iipsrv.log:

Unsupported image type: /path/to/file/image.jp2

This behaviour is confirmed by the thread at https://sourceforge.net/p/iipimage/discussion/299494/thread/83c834bd/

As per https://github.com/ruven/iipsrv#optional-libraries-openjpeg --enable-openjpeg would need to be used when compiling to enable the open source OpenJPEG decoder.
