# SPQR lib usually requires linking to a blas and lapack library.

# It is up to the user of this module to find a BLAS and link to it.

# SPQR lib requires Cholmod, colamd and amd as well.

# FindCholmod.cmake can be used to find those packages before finding spqr

# This module first tries to find SPQR 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.
