Subject: [PATCH] opencascade and gmsh: export CASROOT, fix libs

- opencascade support inside gmsh is needed for deal.II.
- gmsh finds opencascade using the CASROOT env variable, so export it
when we install opencascade.
- set rpath in gmsh installation to be able to find libs
- disable petsc/slepc in gmsh (not needed)
