Inclusion of align-image-stack in a Flatpak

Please ignore answer #1 which is no longer a problem.

This now gets a bit further, any idea what I need to do to fix it? Is there any way I can get some help with creating a Flatpak which includes align_image_stack?

We don't provide a flatpak of Hugin. But there is a flatpak of Hugin available on flathub https://flathub.org/apps/details/net.sourceforge.Hugin (also linked on download page). Maybe you will find there more information about the flatpak.

That's just a link to the app. Where may I find the Flatpak manifest for Hugin or just align-image-stack?

The flatpak was provided by the community. I have no knowledge about the details. But there is link called "see details" with more information in a github repository.

It fails to build with the message below, I assume that would happen whether it was built for a Flatpak or not. Would the error be in align-image-stack itself, or caused by one of the constituent modules (wxWidgets, libpano13, ilmbase, openexr, vigra, exiv2, boost)?
