+        # The issue is that the JIT compilation setup fails with cmake errors when
+        # opm is present. Cmake complains that the SuperLU::SuperLU target is not found
+        # (and maybe also SuiteSparse). OPM has its own find modules for these two, and 
+        # (maybe) overwrites some compiler flags. Upstream fixes would be to either allow
+        # "deactivation" of certain python modules (here: opm), or fixing the incompatibility
+        # of the find modules (although this doesn't appear to be an issue in C++). For now,
+        # one fix is to overwrite the find modules in opm with those of dune before setting
+        # up the dune python environment.
