> configure: error: 'OpenJpeg-2' is required but the header (openjpeg.h) doesn't seem to be installed on this system

The openjpeg-2.3 directory is not checked, and the conditional in the code only supports 2.0, 2.1 or 2.2.

The following patch was added to the Debian package:

Description: Add support for OpenJPEG 2.3.
Author: Bas Couwennberg <sebastic@debian.org>
Bug: https://www.gaia-gis.it/fossil/librasterlite2/info/f3f2e7d32bf737e7

Changing the config script for every minor openjpeg version bump doesn't scale.

Please use pkg-config instead. GDAL has started doing this recently too, see:
