Trilinos packages have been deprecated (intended for removal in 2025)

[mmuetzel]

From upstream Trilinos version 16.0:
https://github.com/trilinos/Trilinos/blob/trilinos-release-16-0-branch/RELEASE_NOTES#L8-L30

A large number of packages have been marked as deprecated in this release. We are planning to remove them in the fall of 2025. The list of packages is

• Amesos
• AztecOO
• Epetra
• EpetraExt
• Ifpack
• Intrepid
• Isorropia
• ML
• NewPackage
• Pliris
• PyTrilinos
• ShyLU_DDCore
• ThyraEpetraAdapters
• ThyraEpetraExtAdapters
• Triutils

If you are a user of one of these packages, please transition to the newer software stack. If you need guidance with finding an adequate replacement or are missing a particular feature, please open an issue or a discussion on Github.

Afaict, at least the following of these are used by ElmerFEM (at least I had to enable them manually in Trilinos 16.0 so ElmerFEM didn't fail to build or link):

• AztecOO
• Epetra
• EpetraExt
• ML
