Bug#1074332: openboard: Fails to build with poppler 24.06

[Jeremy Bícha]

Source: openboard
Version: 1.6.4+dfsg-1
Severity: important
Tags: ftbfs patch

openboard fails to build with poppler 24.06 available in Debian experimental.

A patch to fix this issue is available at
https://launchpad.net/ubuntu/+source/openboard/1.6.4+dfsg-1ubuntu1

Alternatively, Andreas Hasenack recommended updating openboard to
1.7.1 ( https://bugs.debian.org/1074331 ) and then applying these
commits:
https://github.com/OpenBoard-org/OpenBoard/pull/961
https://github.com/OpenBoard-org/OpenBoard/pull/962
https://github.com/OpenBoard-org/OpenBoard/pull/1001 (this last one
might not be required but it cleans up deprecations, some of which are
newly reported after the switch to build using C++20.)

and set -DCMAKE_CXX_STANDARD=20 in your dh_auto_configure override.

Thank you,
Jeremy Bícha
