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::gtest_main`` The Google Test ``gtest_main`` library, if found For backwards compatibility, this module defines additionally the following deprecated :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::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. #]=======================================================================] include(${CMAKE_CURRENT_LIST_DIR}/GoogleTest.cmake) function(__gtest_append_debugs _endvar _library) if(${_library} AND ${_library}_DEBUG) set(_output optimized ${${_library}} debug ${${_library}_DEBUG}) else() set(_output ${${_library}}) endif() set(${_endvar} ${_output} PARENT_SCOPE) endfunction() function(__gtest_find_library _name) find_library(${_name} NAMES ${ARGN} HINTS ENV GTEST_ROOT ${GTEST_ROOT} PATH_SUFFIXES ${_gtest_libpath_suffixes} ) mark_as_advanced(${_name}) endfunction() macro(__gtest_determine_windows_library_type _var) if(EXISTS "${${_var}}") file(TO_NATIVE_PATH "${${_var}}" _lib_path) get_filename_component(_name "${${_var}}" NAME_WE) file(STRINGS "${${_var}}" _match REGEX "${_name}\\.dll" LIMIT_COUNT 1) if(NOT _match STREQUAL "") set(${_var}_TYPE SHARED PARENT_SCOPE) else() set(${_var}_TYPE UNKNOWN PARENT_SCOPE) endif() return() endif() endmacro() function(__gtest_determine_library_type _var) if(WIN32) #
