  class Butterflypack(CMakePackage):
      """ButterflyPACK is a mathematical software for rapidly solving
      large-scale dense linear systems that exhibit off-diagonal rank-deficiency.
      These systems arise frequently from boundary element methods, or
      factorization phases in finite-difference/finite-element methods.
      ButterflyPACK relies on low-rank or butterfly formats under Hierarchical
      matrix, HODLR or other hierarchically nested frameworks to compress,
      factor and solve the linear system in quasi-linear time. The
      computationally most intensive phase, factorization, is accelerated via
      randomized linear algebras. The butterfly format, originally inspired by
      the butterfly data flow in fast Fourier Transform, is a linear algebra tool
      well-suited for compressing matrices arising from high-frequency wave
      equations or highly oscillatory integral operators."""
