Determining correct order of Trilinos libraries in link line

[jhux2]

Is there a mechanism for an application building against an installed Trilinos build to identify the proper link ordering for Trilinos libraries? If it matters, the customer is doing a static build. I don't know if the app itself is using cmake.

Currently the only supported approach is to have downstream apps use CMake and pull in Trilinos pacakges with find_package(<PackageName>) and then link to target_link_libraries(<yourLibOrExec> PRIVATE <PackageName>::all_libs ...). This was one of the consequences of moving to modern CMake. See the discussion of this in TriBITSPub/TriBITS#299 starting around TriBITSPub/TriBITS#299 (comment) (and see Kitware's view on this in TriBITSPub/TriBITS#299 (comment)).
