| # 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 |
