# KLU lib usually requires linking to a blas library.
# It is up to the user of this module to find a BLAS and link to it.
#
# This module first tries to find KLU via its CMake config-mode package
# (shipped with SuiteSparse >= 7.0). If that fails, it falls back to a
# manual header/library search for compatibility with older installations.
