Link to static versions of sundails for FMUs. (#8377)

  - We build both static and shared versions of sundials libs.
    The shared versions are needed for the cpp runtime.

    If we are generating static FMUs with CVODE as a solver we
    link to `cvode` and `nvecserial`. Make sure we link to the static versions
    of this libraries.
