+# OpenBLAS cmake module.
+# This module sets the following variables in your project::
+#
+#   OpenBLAS_FOUND - true if OpenBLAS and all required components found on the system
+#   OpenBLAS_VERSION - OpenBLAS version in format Major.Minor.Release
+#   OpenBLAS_INCLUDE_DIRS - Directory where OpenBLAS header is located.
+#   OpenBLAS_INCLUDE_DIR - same as DIRS
+#   OpenBLAS_LIBRARIES - OpenBLAS library to link against.
+#   OpenBLAS_LIBRARY - same as LIBRARIES
+#
+#
+# Available components::
+#
+##   shared - search for only shared library
+##   static - search for only static library
+#   serial - search for unthreaded library
+#   pthread - search for native pthread threaded library
+#   openmp - search for OpenMP threaded library
+#
+#
+# Exported targets::
+#
+# If OpenBLAS is found, this module defines the following :prop_tgt:`IMPORTED`
+## target. Target is shared _or_ static, so, for both, use separate, not
+## overlapping, installations. ::
+#
+#   OpenBLAS::OpenBLAS - the main OpenBLAS library #with header & defs attached.
+#
+#
+# Suggested usage::
+#
+#   find_package(OpenBLAS)
+#   find_package(OpenBLAS 0.2.20 EXACT CONFIG REQUIRED COMPONENTS pthread)
+#
+#
+# The following variables can be set to guide the search for this package::
+#
+#   OpenBLAS_DIR - CMake variable, set to directory containing this Config file
+#   CMAKE_PREFIX_PATH - CMake variable, set to root directory of this package
+#   PATH - environment variable, set to bin directory of this package
+#   CMAKE_DISABLE_FIND_PACKAGE_OpenBLAS - CMake variable, disables
+#     find_package(OpenBLAS) when not REQUIRED, perhaps to force internal build
