A script which has details of the relevant configuration options for Trilinos is available at the ARCHER2 Github repository. The script will build a static-only version of the libraries.

$ git clone https://github.com/ARCHER2-HPC/pe-scripts.git
$ cd pe-scripts
$ git checkout cse-develop
$ ...
$ ./sh/trilinos.sh --prefix=/path/to/install/location
where --prefix sets the installation location. The ellipsis ... is standing for the dependencies used to build Trilinos, which here are: metis, parmetis, superlu, superlu-dist, scotch, mumps, glm, boost. These packages should be built as described in their corresponding pages linked in the menu on the left.
