        finite element meshes, and producing fill reducing orderings for sparse

        matrices. The algorithms implemented in METIS are based on the multilevel

        schemes developed in our lab.

Use,

build:
  ignore_run_exports:
    - libstdcxx-ng
    - libcxx

and you'll see that the C++ runtimes are not in run requirements.

[SylvainCorlay]

Yeah but it feels wrong to use the actual name of the package.

[jakirkham]

What if we just patch the CMakeLists.txt for now? Arguably that's what they should do anyways. 😉
