| # FindGTest |
| # --------- |
| # |
| # Locate the Google C++ Testing Framework. |
| # |
| # Defines the following variables: |
| # |
| # :: |
| # |
| # GTEST_FOUND - Found the Google Testing framework |
| # GTEST_INCLUDE_DIRS - Include directories |
| # |
| # |
| # |
| # Also defines the library variables below as normal variables. These |
| # contain debug/optimized keywords when a debugging library is found. |
| # |
| # :: |
| # |
| # GTEST_BOTH_LIBRARIES - Both libgtest & libgtest-main |
| # GTEST_LIBRARIES - libgtest |
| # GTEST_MAIN_LIBRARIES - libgtest-main |
| # |
| # |
| # |
| # Accepts the following variables as input: |
| # |
| # :: |
| # |
| # GTEST_ROOT - (as a CMake or environment variable) |
| # The root directory of the gtest install prefix |
| # |
| # |
| # |
| # :: |
| # |
| # GTEST_MSVC_SEARCH - If compiling with MSVC, this variable can be set to |
| # "MD" or "MT" to enable searching a GTest build tree |
| # (defaults: "MD") |
| # |
| # |
| # |
| # Example Usage: |
| # |
| # :: |
| # |
| # enable_testing() |
| # find_package(GTest REQUIRED) |
| # include_directories(${GTEST_INCLUDE_DIRS}) |
| # |
| # |
| # |
| # :: |
| # |
| # add_executable(foo foo.cc) |
| # target_link_libraries(foo ${GTEST_BOTH_LIBRARIES}) |
| # |
| # |
| # |
| # :: |
| # |
| # add_test(AllTestsInFoo foo) |
| # |
| # |
| # |
| # |
| # |
| # If you would like each Google test to show up in CTest as a test you |
| # may use the following macro. NOTE: It will slow down your tests by |
| # running an executable for each test and test fixture. You will also |
| # have to rerun CMake after adding or removing tests or test fixtures. |
| # |
| # GTEST_ADD_TESTS(executable extra_args ARGN) |
| # |
| # :: |
| # |
| # executable = The path to the test executable |
| # extra_args = Pass a list of extra arguments to be passed to |
| # executable enclosed in quotes (or "" for none) |
| # ARGN = A list of source files to search for tests & test |
| # fixtures. Or AUTO to find them from executable target. |
| # |
| # |
| # |
| # :: |
| # |
| # Example: |
| # set(FooTestArgs --foo 1 --bar 2) |
| # add_executable(FooTest FooUnitTest.cc) |
| # GTEST_ADD_TESTS(FooTest "${FooTestArgs}" AUTO) |
