+#                              framework, introduced in Xcode 9.0 (2017).
+#                              Note that this is distinct from the Accelerate
+#                              framework on its own, which existed in previous
+#                              versions but without the sparse solvers.
+#
+# This module defines the following variables which should be referenced
+# by the caller to use the library.
+#
+# AccelerateSparse_FOUND: TRUE iff an Accelerate framework including the sparse
+#                         solvers, and all dependencies, has been found.
+# AccelerateSparse_INCLUDE_DIRS: Include directories for Accelerate framework.
+# AccelerateSparse_LIBRARIES: Libraries for Accelerate framework and all
+#                             dependencies.
+#
+# 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.
+#
+# AccelerateSparse_INCLUDE_DIR: Include directory for Accelerate framework, not
+#                               including the include directory of any
+#                               dependencies.
