+# Locate the Google C++ Mocking Framework.
+# (This file is almost an identical copy of the original FindGTest.cmake file,
+#  feel free to use it as it is or modify it for your own needs.)
+#
+#
+# Defines the following variables:
+#
+#   GMOCK_FOUND - Found the Google Testing framework
+#   GMOCK_INCLUDE_DIRS - Include directories
+#
+# Also defines the library variables below as normal
+# variables. These contain debug/optimized keywords when
+# a debugging library is found.
+#
+#   GMOCK_BOTH_LIBRARIES - Both libgmock & libgmock-main
+#   GMOCK_LIBRARIES - libgmock
+#   GMOCK_MAIN_LIBRARIES - libgmock-main
+#
+# Accepts the following variables as input:
+#
+#   GMOCK_ROOT - (as a CMake or environment variable)
+#                The root directory of the gmock install prefix
+#
+#   GMOCK_MSVC_SEARCH - If compiling with MSVC, this variable can be set to
+#                       "MD" or "MT" to enable searching a gmock build tree
+#                       (defaults: "MD")
+#
+#-----------------------
+# Example Usage:
+#
+#    find_package(GMock REQUIRED)
+#    include_directories(${GMOCK_INCLUDE_DIRS})
+#
+#    add_executable(foo foo.cc)
+#    target_link_libraries(foo ${GMOCK_BOTH_LIBRARIES})
