 # FindCXSparse.cmake - Find CXSparse libraries & dependencies.
 #
 # This module defines the following variables which should be referenced
 # by the caller to use the library.
 #
 # CXSPARSE_FOUND: TRUE iff CXSparse and all dependencies have been found.
 # CXSPARSE_INCLUDE_DIRS: Include directories for CXSparse.
 # CXSPARSE_LIBRARIES: Libraries for CXSparse and all dependencies.
 #
 # CXSPARSE_VERSION: Extracted from cs.h.
 # CXSPARSE_MAIN_VERSION: Equal to 3 if CXSPARSE_VERSION = 3.1.2
 # CXSPARSE_SUB_VERSION: Equal to 1 if CXSPARSE_VERSION = 3.1.2
 # CXSPARSE_SUBSUB_VERSION: Equal to 2 if CXSPARSE_VERSION = 3.1.2
 #
 # The following variables control the behaviour of this module:
 #
 # CXSPARSE_INCLUDE_DIR_HINTS: List of additional directories in which to
 #                             search for CXSparse includes,
 #                             e.g: /timbuktu/include.
 # CXSPARSE_LIBRARY_DIR_HINTS: List of additional directories in which to
 #                             search for CXSparse libraries, e.g: /timbuktu/lib.
 #
 # The following variables are also defined by this module, but in line with
 # CMake recommended FindPackage() module style should NOT be referenced directly
 # by callers (use the plural variables detailed above instead).  These variables
 # do however affect the behaviour of the module via FIND_[PATH/LIBRARY]() which
 # are NOT re-called (i.e. search for library is not repeated) if these variables
 # are set with valid values _in the CMake cache_. This means that if these
 # variables are set directly in the cache, either by the user in the CMake GUI,
 # or by the user passing -DVAR=VALUE directives to CMake when called (which
 # explicitly defines a cache variable), then they will be used verbatim,
 # bypassing the HINTS variables and other hard-coded search locations.
 #
 # CXSPARSE_INCLUDE_DIR: Include directory for CXSparse, not including the
 #                       include directory of any dependencies.
 # CXSPARSE_LIBRARY: CXSparse library, not including the libraries of any
 #                   dependencies.

 # Called if we failed to find CXSparse or any of it's required dependencies,
 # unsets all public (designed to be used externally) variables and reports
 # error message at priority depending upon [REQUIRED/QUIET/<NONE>] argument.
