Bug Report

ShyLU requires Epetra. I don't think this is actually correct though. One should be able to enable FROSch without Epetra.

ShyLU has a required dependency on ShyLU_DD: https://github.com/trilinos/Trilinos/blob/bee69a658e891fb37c6716b1394ed31f5f6feb8b/packages/shylu/cmake/Dependencies.cmake#L1 ShyLU_DD has a required dependency on Core https://github.com/trilinos/Trilinos/blob/bee69a658e891fb37c6716b1394ed31f5f6feb8b/packages/shylu/shylu_dd/cmake/Dependencies.cmake#L7 Core has a required dependency on the Epetra stack https://github.com/trilinos/Trilinos/blob/bee69a658e891fb37c6716b1394ed31f5f6feb8b/packages/shylu/shylu_dd/core/cmake/Dependencies.cmake#L1
