FindGTest
---------
Locate the Google C++ Testing Framework.
.. versionadded:: 3.20
Upstream ``GTestConfig.cmake`` is used if possible.
Imported targets
^^^^^^^^^^^^^^^^
.. versionadded:: 3.20
This module defines the following :prop_tgt:`IMPORTED` targets:
``GTest::gtest``
The Google Test ``gtest`` library, if found; adds Thread::Thread
automatically
``GTest::gtest_main``
The Google Test ``gtest_main`` library, if found
.. versionadded:: 3.23
``GTest::gmock``
The Google Mock ``gmock`` library, if found; adds Thread::Thread
automatically
``GTest::gmock_main``
The Google Mock ``gmock_main`` library, if found
.. deprecated:: 3.20
For backwards compatibility, this module defines additionally the
following deprecated :prop_tgt:`IMPORTED` targets (available since 3.5):
``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::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.
.. versionchanged:: 3.9
Previous CMake versions defined :command:`gtest_add_tests` macro in this
module.
