Thank you for your contribution!
Can you lower the requirement to deal.II 9.5.0? We at some point established that code gallery programs should compile with 9.5.0 and younger.
If your code does not compile with the older versions, you can work around it like in 42e8901.

@marcfehling Do we need this requirement? Could we allow programs to just require newer versions (or in fact change all programs to just build for, say, 9.6)?

Sure, we can drop the requirement for deal.II 9.5. We didn't bump the version since summer 2023 #155.
Yet, this program still needs to compile with deal.II 9.6.

This PR presents a DG solver for the Poisson problem on general polytopal meshes generated through mesh agglomeration. Starting from a fine mesh, we construct a coarser agglomerated mesh on which the DG discretization is performed.
This set of files have been extracted from the Polydeal library, a deal.II-based framework for working with agglomerated grids.
While the overall structure of
poisson.cclargely follows that of a standard Poisson solver in deal.II, differences related to the usage of agglomerated meshes still need to be commented, so the PR remains a draft for now.
