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.
