# 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`
|
|
# command.
