# While Metis is a pure C library, it is built with cmake, which assumes C++
# by defaults and attempts to locate the C++ compiler. Hence the recipe has a
# build dependency on {{ compiler('cxx') }}. The `ignore_run_exports` entry is
# added so that the package does not depend on the C++ runtime due to the
# dependency to the C++ compiler.
#
# Another fix to this would be to have metis' cmake specify `project(METIS C)`
# instead of `project(METIS)`.

  summary: 'METIS - Serial Graph Partitioning and Fill-reducing Matrix Ordering'
  description: |
    METIS is a set of serial programs for partitioning graphs, partitioning
    finite element meshes, and producing fill reducing orderings for sparse
    matrices. The algorithms implemented in METIS are based on the multilevel
    recursive-bisection, multilevel k-way, and multi-constraint partitioning
    schemes developed in our lab.
