# Tries to find GTest headers and libraries.
#
# Usage of this module as follows:
#
# find_package(GTest)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# GTest_HOME - When set, this path is inspected instead of standard library
# locations as the root of the GTest installation.
# The environment variable GTEST_HOME overrides this veriable.
#
# This module defines
# GTEST_INCLUDE_DIR, directory containing headers
# GTEST_LIBS, directory containing gtest libraries
# GTEST_STATIC_LIB, path to libgtest.a
# GTEST_MAIN_STATIC_LIB, path to libgtest_main.a
# GTEST_SHARED_LIB, path to libgtest's shared library
# GTEST_FOUND, whether gtest has been found
