Error when converting from PetscInt to Label

Hello team,

I'm trying to build it using intel compiler 19.1 and intel-mpi 2018.
However I get the following error:

icpc: command line warning #10148: option '-Wno-old-style-cast' not supported solvers/petscSolver.C(159): error: a reference of type "Foam::List<Foam::label={int64_t={__int64_t={signed long}}}> &" (not const-qualified) cannot be initialized with a value of type "Foam::List<PetscInt={PetscInt64={long long}}>" List& lowNonZero = ctx.lowNonZero;

When I compile OpenFoam and petsc with gcc and open-mpi everything runs fine, but not with intel. Would you please have a look upon it? Thank you very much. Pablo
