-    ${GTEST_DIR}/src/gtest-all.cc
+#### Standalone CMake Project
 
-with `${GTEST_DIR}/include` in the system header search path and `${GTEST_DIR}`
+When building GoogleTest as a standalone project, the typical workflow starts
-in the normal header search path.  Assuming a Linux-like system and gcc,
+with
-something like the following will do:
 
-    g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
+```
-        -pthread -c ${GTEST_DIR}/src/gtest-all.cc
+git clone https://github.com/google/googletest.git -b release-1.10.0
-    ar -rv libgtest.a gtest-all.o
+cd googletest        # Main directory of the cloned repository.
+mkdir build          # Create a directory to hold the build output.
+cd build
+cmake ..             # Generate native build scripts for GoogleTest.
+```
 
-(We need `-pthread` as Google Test uses threads.)
+The above command also includes GoogleMock by default. And so, if you want to
+build only GoogleTest, you should replace the last command with
 
-Next, you should compile your test source file with
+```
-`${GTEST_DIR}/include` in the system header search path, and link it
+cmake .. -DBUILD_GMOCK=OFF
-with gtest and any other necessary libraries:

+If you are on a \*nix system, you should now see a Makefile in the current
-        -o your_test
+directory. Just type `make` to build GoogleTest. And then you can simply install
+GoogleTest if you are a system administrator.
 
-As an example, the make/ directory contains a Makefile that you can

-(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google

-    make
-    ./sample1_unittest
-
-If you see errors, try to tweak the contents of `make/Makefile` to make
-them go away.  There are instructions in `make/Makefile` on how to do
-it.

-### Using CMake ###
-
-Google Test comes with a CMake build script (
-[CMakeLists.txt](CMakeLists.txt)) that can be used on a wide range of platforms ("C" stands for
-cross-platform.). If you don't have CMake installed already, you can
-download it for free from <http://www.cmake.org/>.
-
-CMake works by generating native makefiles or build projects that can
-be used in the compiler environment of your choice.  The typical
-workflow starts with:
-
-    mkdir mybuild       # Create a directory to hold the build output.
-    cd mybuild
-    cmake ${GTEST_DIR}  # Generate native build scripts.
-
-If you want to build Google Test's samples, you should replace the
-last command with
-
-    cmake -Dgtest_build_samples=ON ${GTEST_DIR}
-
-If you are on a \*nix system, you should now see a Makefile in the
-current directory.  Just type 'make' to build gtest.
-
-If you use Windows and have Visual Studio installed, a `gtest.sln` file
-and several `.vcproj` files will be created.  You can then build them
-using Visual Studio.
 
 On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
 
-### Legacy Build Scripts ###
+#### Incorporating Into An Existing CMake Project
 
-Before settling on CMake, we have been providing hand-maintained build
+If you want to use GoogleTest in a project which already uses CMake, the easiest
-projects/scripts for Visual Studio, Xcode, and Autotools.  While we
+way is to get installed libraries and headers.
-continue to provide them for convenience, they are not actively
-maintained any more.  We highly recommend that you follow the
-instructions in the previous two sections to integrate Google Test
-with your existing build system.
 
-If you still need to use the legacy build scripts, here's how:
+*   Import GoogleTest by using `find_package` (or `pkg_check_modules`). For
+    example, if `find_package(GTest CONFIG REQUIRED)` succeeds, you can use the
+    libraries as `GTest::gtest`, `GTest::gmock`.
 
-The msvc\ folder contains two solutions with Visual C++ projects.
+And a more robust and flexible approach is to build GoogleTest as part of that
-Open the `gtest.sln` or `gtest-md.sln` file using Visual Studio, and you
+project directly. This is done by making the GoogleTest source code available to
-are ready to build Google Test the same way you build any Visual
+the main build and adding it using CMake's `add_subdirectory()` command. This
-Studio project.  Files that have names ending with -md use DLL
+has the significant advantage that the same compiler and linker settings are
-versions of Microsoft runtime libraries (the /MD or the /MDd compiler
+used between GoogleTest and the rest of your project, so issues associated with
-option).  Files without that suffix use static versions of the runtime
+using incompatible libraries (eg debug/release), etc. are avoided. This is
-libraries (the /MT or the /MTd option).  Please note that one must use
+particularly useful on Windows. Making GoogleTest's source code available to the
-the same option to compile both gtest and the test code.  If you use
+main build can be done a few different ways:
-Visual Studio 2005 or above, we recommend the -md version as /MD is
-the default for new projects in these versions of Visual Studio.
 
-On Mac OS X, open the `gtest.xcodeproj` in the `xcode/` folder using
+*   Download the GoogleTest source code manually and place it at a known
-Xcode.  Build the "gtest" target.  The universal binary framework will
+    location. This is the least flexible approach and can make it more difficult
-end up in your selected build directory (selected in the Xcode
+    to use with continuous integration systems, etc.
-"Preferences..." -> "Building" pane and defaults to xcode/build).
+*   Embed the GoogleTest source code as a direct copy in the main project's
-Alternatively, at the command line, enter:
+    source tree. This is often the simplest approach, but is also the hardest to
+    keep up to date. Some organizations may not permit this method.
+*   Add GoogleTest as a git submodule or equivalent. This may not always be
+    possible or appropriate. Git submodules, for example, have their own set of
+    advantages and drawbacks.
+*   Use CMake to download GoogleTest as part of the build's configure step. This
+    approach doesn't have the limitations of the other methods.
 
-    xcodebuild
+The last of the above methods is implemented with a small piece of CMake code
+that downloads and pulls the GoogleTest code into the main build.
 
-This will build the "Release" configuration of gtest.framework in your
+Just add to your `CMakeLists.txt`:
-default build location.  See the "xcodebuild" man page for more
-information about building different configurations and building in
-different locations.
 
-If you wish to use the Google Test Xcode project with Xcode 4.x and
+```cmake
-above, you need to either:
+include(FetchContent)
+FetchContent_Declare(
+  googletest
+  # Specify the commit you depend on and update it regularly.
+  URL https://github.com/google/googletest/archive/609281088cfefc76f9d0ce82e1ff6c30cc3591e5.zip
+)
+# For Windows: Prevent overriding the parent project's compiler/linker settings
+set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
+FetchContent_MakeAvailable(googletest)
 
- * update the SDK configuration options in xcode/Config/General.xconfig.
+# Now simply link against gtest or gtest_main as needed. Eg
-   Comment options `SDKROOT`, `MACOS_DEPLOYMENT_TARGET`, and `GCC_VERSION`. If
+add_executable(example example.cpp)
-   you choose this route you lose the ability to target earlier versions
+target_link_libraries(example gtest_main)
-   of MacOS X.
+add_test(NAME example_test COMMAND example)
- * Install an SDK for an earlier version. This doesn't appear to be
+```
-   supported by Apple, but has been reported to work
-   (http://stackoverflow.com/questions/5378518).
 
-### Tweaking Google Test ###
+Note that this approach requires CMake 3.14 or later due to its use of the
+`FetchContent_MakeAvailable()` command.
 
-Google Test can be used in diverse environments.  The default
+##### Visual Studio Dynamic vs Static Runtimes
-configuration may not work (or may not work well) out of the box in

-## Developing Google Test ##
-
-This section discusses how to make your own changes to Google Test.
-
-### Testing Google Test Itself ###
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you can use CMake:
-
-    mkdir mybuild
-    cd mybuild
-    cmake -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Make sure you have Python installed, as some of Google Test's tests
-are written in Python.  If the cmake command complains about not being
-able to find Python (`Could NOT find PythonInterp (missing:
-PYTHON_EXECUTABLE)`), try telling it explicitly where your Python
-executable can be found:
-
-    cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Next, you can build Google Test and all of its own tests.  On \*nix,
-this is usually done by 'make'.  To run the tests, do
-
-    make test
-
-All tests should pass.
-
-Normally you don't need to worry about regenerating the source files,
-unless you need to modify them.  In that case, you should modify the
-corresponding .pump files instead and run the pump.py Python script to
-regenerate them.  You can find pump.py in the [scripts/](scripts/) directory.
-Read the [Pump manual](docs/PumpManual.md) for how to use it.

+# Customization Points
+
+The custom directory is an injection point for custom user configurations.
+
+## Header `gtest.h`
+
+### The following macros can be defined:
+
+*   `GTEST_OS_STACK_TRACE_GETTER_` - The name of an implementation of
+    `OsStackTraceGetterInterface`.
+*   `GTEST_CUSTOM_TEMPDIR_FUNCTION_` - An override for `testing::TempDir()`. See
+    `testing::TempDir` for semantics and signature.
+
+## Header `gtest-port.h`
+
+The following macros can be defined:
+
+### Flag related macros:
+
+*   `GTEST_FLAG(flag_name)`
+*   `GTEST_USE_OWN_FLAGFILE_FLAG_` - Define to 0 when the system provides its
+    own flagfile flag parsing.
+*   `GTEST_DECLARE_bool_(name)`
+*   `GTEST_DECLARE_int32_(name)`
+*   `GTEST_DECLARE_string_(name)`
+*   `GTEST_DEFINE_bool_(name, default_val, doc)`
+*   `GTEST_DEFINE_int32_(name, default_val, doc)`
+*   `GTEST_DEFINE_string_(name, default_val, doc)`
+
+### Logging:
+
+*   `GTEST_LOG_(severity)`
+*   `GTEST_CHECK_(condition)`
+*   Functions `LogToStderr()` and `FlushInfoLog()` have to be provided too.
+
+### Threading:
+
+*   `GTEST_HAS_NOTIFICATION_` - Enabled if Notification is already provided.
+*   `GTEST_HAS_MUTEX_AND_THREAD_LOCAL_` - Enabled if `Mutex` and `ThreadLocal`
+    are already provided. Must also provide `GTEST_DECLARE_STATIC_MUTEX_(mutex)`
+    and `GTEST_DEFINE_STATIC_MUTEX_(mutex)`
+*   `GTEST_EXCLUSIVE_LOCK_REQUIRED_(locks)`
+*   `GTEST_LOCK_EXCLUDED_(locks)`
+
+### Underlying library support features
+
+*   `GTEST_HAS_CXXABI_H_`
+
+### Exporting API symbols:
+
+*   `GTEST_API_` - Specifier for exported symbols.
+
+## Header `gtest-printers.h`
+
+*   See documentation at `gtest/gtest-printers.h` for details on how to define a
+    custom printer.

-// This macro is used for implementing macros such as

-// Parameters:
-//   statement -  A statement that a macro such as EXPECT_DEATH would test
-//                for program termination. This macro has to make sure this
-//                statement is compiled but not executed, to ensure that

-//                parameter iff EXPECT_DEATH compiles with it.
-//   regex     -  A regex that a macro such as EXPECT_DEATH would use to test
-//                the output of statement.  This parameter has to be
-//                compiled but not evaluated by this macro, to ensure that
-//                this macro only accepts expressions that a macro such as
-//                EXPECT_DEATH would accept.
-//   terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
-//                and a return statement for ASSERT_DEATH_IF_SUPPORTED.
-//                This ensures that ASSERT_DEATH_IF_SUPPORTED will not

-//                compile.
-//
-//  The branch that has an always false condition is used to ensure that
