| FindGTest |
| --------- |
| |
| Locate the Google C++ Testing Framework. |
| |
| Imported targets |
| ^^^^^^^^^^^^^^^^ |
| |
| This module defines the following :prop_tgt:`IMPORTED` targets: |
| |
| ``GTest::GTest`` |
| The Google Test ``gtest`` library, if found; adds Thread::Thread |
| automatically |
| ``GTest::Main`` |
| The Google Test ``gtest_main`` library, if found |
| |
| |
| Result variables |
| ^^^^^^^^^^^^^^^^ |
| |
| This module will set the following variables in your project: |
| |
| ``GTEST_FOUND`` |
| Found the Google Testing framework |
| ``GTEST_INCLUDE_DIRS`` |
| the directory containing the Google Test headers |
| |
| The library variables below are set as normal variables. These |
| contain debug/optimized keywords when a debugging library is found. |
| |
| ``GTEST_LIBRARIES`` |
| The Google Test ``gtest`` library; note it also requires linking |
| with an appropriate thread library |
| ``GTEST_MAIN_LIBRARIES`` |
| The Google Test ``gtest_main`` library |
| ``GTEST_BOTH_LIBRARIES`` |
| Both ``gtest`` and ``gtest_main`` |
| |
| Cache variables |
| ^^^^^^^^^^^^^^^ |
| |
| The following cache variables may also be set: |
| |
| ``GTEST_ROOT`` |
| The root directory of the Google Test installation (may also be |
| set as an environment variable) |
| ``GTEST_MSVC_SEARCH`` |
| If compiling with MSVC, this variable can be set to ``MT`` or |
| ``MD`` (the default) to enable searching a GTest build tree |
| |
| |
| Example usage |
| ^^^^^^^^^^^^^ |
| |
| :: |
| |
| enable_testing() |
| find_package(GTest REQUIRED) |
| |
| add_executable(foo foo.cc) |
| target_link_libraries(foo GTest::GTest GTest::Main) |
| |
| add_test(AllTestsInFoo foo) |
| |
| |
| Deeper integration with CTest |
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| |
| See :module:`GoogleTest` for information on the :command:`gtest_add_tests` |
| and :command:`gtest_discover_tests` commands. |
