FindGTest — CMake 3.27.7 Documentation

# FindGTest

Locate the Google C++ Testing Framework.

New in version 3.20: Upstream `GTestConfig.cmake` is used if possible.

## Imported targets

New in version 3.20: This module defines the following `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

New in version 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 since version 3.20: For backwards compatibility, this module defines additionally the following deprecated `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 `GoogleTest` for information on the `gtest_add_tests()` and `gtest_discover_tests()` commands.

Changed in version 3.9: Previous CMake versions defined `gtest_add_tests()` macro in this module.
