Provide compilation option for existing dumux installation

[Fujikawas]

With this change, it would be possible to specify the path to a complete DuMux installation along with other DUNE-Modules while running solvers in DuMux.
Also moved the compilation step into the running script.

Checklist:

• I added a summary of any user-facing changes (compared to the last release) in the changelog-entries/<PRnumber>.md.
• I will remember to squash-and-merge, providing a useful summary of the changes of this PR.

I tried to run the participants by providing the path to a folder that consists of DUNE modules that the case needs, and I got the following error:

Yes. But it is in the folder dumux-adapter/.
