PetscErrorCode PetscHasExternalPackage(const char pkg[], PetscBool *has)
Not Collective
Input Parameter#

Output Parameter#
- has - - PETSC_TRUEif PETSc is configured with the given package, else- PETSC_FALSE.
Notes#
This is basically an alternative for PETSC_HAVE_XXX whenever a preprocessor macro is not available/desirable, e.g. in Python.
The external package name pkg is e.g. “hdf5”, “yaml”, “parmetis”.
It should correspond to the name listed in  ./configure --help  or e.g. in PetscViewerType, MatPartitioningType, MatSolverType.
The lookup is case insensitive, i.e. looking for “HDF5” or “hdf5” is the same.
