# FindSuiteSparse.cmake - Find SuiteSparse libraries & dependencies.
#
# This module defines the following variables:
#
# SUITESPARSE_FOUND: TRUE iff SuiteSparse and all dependencies have been found.
# SUITESPARSE_INCLUDE_DIRS: Include directories for all SuiteSparse components.
# SUITESPARSE_LIBRARIES: Libraries for all SuiteSparse component libraries and
# dependencies.
# SUITESPARSE_VERSION: Extracted from UFconfig.h (<= v3) or
# SuiteSparse_config.h (>= v4).
# SUITESPARSE_MAIN_VERSION: Equal to 4 if SUITESPARSE_VERSION = 4.2.1
# SUITESPARSE_SUB_VERSION: Equal to 2 if SUITESPARSE_VERSION = 4.2.1
# SUITESPARSE_SUBSUB_VERSION: Equal to 1 if SUITESPARSE_VERSION = 4.2.1
#
# SUITESPARSE_IS_BROKEN_SHARED_LINKING_UBUNTU_SYSTEM_VERSION: TRUE iff running
# on Ubuntu, SUITESPARSE_VERSION is 3.4.0 and found SuiteSparse is a system
# install, in which case found version of SuiteSparse cannot be used to link
# a shared library due to a bug (static linking is unaffected).
#
# The following variables control the behaviour of this module:
#
# SUITESPARSE_INCLUDE_DIR_HINTS: List of additional directories in which to
# search for SuiteSparse includes,
# e.g: /timbuktu/include.
# SUITESPARSE_LIBRARY_DIR_HINTS: List of additional directories in which to
# search for SuiteSparse libraries,
# e.g: /timbuktu/lib.
#
# The following variables define the presence / includes & libraries for the
# SuiteSparse components searched for, the SUITESPARSE_XX variables are the
# union of the variables for all components.
