SeisSol: Cannot build or run SeisSol

I have tried installing SeisSol using Spack on my machine:

spack install seissol-env +mpi +asagi %gcc@8.3.0 ^openmpi@3.1.5

At first, I had to change the “easi” lib version in the seissol-spack-aid from 1.2 to 1.1.2, as there is no 1.2 release on GitHub.

spack install seissol-env +mpi +asagi %gcc@8.3.0 ^openmpi@3.1.5
==> Error: No valid version for 'easi' satisfies '@1.2'

After doing this, the Spack installation succeeded. However, when I tried to build SeisSol, I encountered this error:

It seems that the PSpaMM library isn’t linked properly, however this should have been handled by Spack. I have been able to replicate this issue while trying to install manually every dependency, so I believe this might be an issue with my entire environment (fresh Ubuntu installation).

Is this a known issue? Or perhaps this is something that I need to manually patch in order to compile and run SeisSol?
