-# 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})
