+# FindGMock
+# ---------
+#
+# Locate the Google C++ Mocking Framework.
+#
+# Imported targets
+# ^^^^^^^^^^^^^^^^
+#
+# This module defines the following :prop_tgt:`IMPORTED` targets:
+#
+# ``GMock::GMock``
+#   The Google Mock ``gmock`` library, if found; adds Thread::Thread
+#   automatically
+# ``GMock::Main``
+#   The Google Mock ``gmock_main`` library, if found
+#
+#
+# Result variables
+# ^^^^^^^^^^^^^^^^
+#
+# This module will set the following variables in your project:
+#
+# ``GMOCK_FOUND``
+#   Found the Google C++ Mocking framework
+# ``GMOCK_INCLUDE_DIRS``
+#   the directory containing the Google Mock headers
+#
+# The library variables below are set as normal variables.  These
+# contain debug/optimized keywords when a debugging library is found.
+#
+# ``GMOCK_LIBRARIES``
+#   The Google Mock ``gmock`` library; note it also requires linking
+#   with an appropriate thread library
+# ``GMOCK_MAIN_LIBRARIES``
+#   The Google Mock ``gmock_main`` library
+# ``GMOCK_BOTH_LIBRARIES``
+#   Both ``gmock`` and ``gmock_main``
+#
+# Cache variables
+# ^^^^^^^^^^^^^^^
+#
+# The following cache variables may also be set:
+#
+# ``GMOCK_ROOT``
+#   The root directory of the Google Mock installation (may also be
+#   set as an environment variable)
+#
+# Example usage
+# ^^^^^^^^^^^^^
+#
+# ::
+#
+#   enable_testing()
+#   find_package(GMock REQUIRED)
+#
+#   add_executable(foo foo.cc)
+#   target_link_libraries(foo GMock::GMock GMock::Main)
