-# Abseil CMake Build Instructions
-
-Abseil 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
-<https://www.cmake.org/>.
-
-CMake works by generating native makefiles or build projects that can
-be used in the compiler environment of your choice.
-
-For API/ABI compatibility reasons, we strongly recommend building Abseil in a
-subdirectory of your project or as an embedded dependency.
-
-## Incorporating Abseil Into a CMake Project
-
-The recommendations below are similar to those for using CMake within the
-googletest framework
-(<https://github.com/google/googletest/blob/master/googletest/README.md#incorporating-into-an-existing-cmake-project>)
-
-### Step-by-Step Instructions
-
-1. If you want to build the Abseil tests, integrate the Abseil dependency
-[Google Test](https://github.com/google/googletest) into your CMake project. To disable Abseil tests, you have to pass
-`-DBUILD_TESTING=OFF` when configuring your project with CMake.
-
-2. Download Abseil and copy it into a subdirectory in your CMake project or add
-Abseil as a [git submodule](https://git-scm.com/docs/git-submodule) in your
-CMake project.
-
-3. You can then use the CMake command
-[`add_subdirectory()`](https://cmake.org/cmake/help/latest/command/add_subdirectory.html)
-to include Abseil directly in your CMake project.
-
-4. Add the **absl::** target you wish to use to the
-[`target_link_libraries()`](https://cmake.org/cmake/help/latest/command/target_link_libraries.html)
-section of your executable or of your library.<br>
-Here is a short CMakeLists.txt example of a project file using Abseil.
-
-```cmake
-cmake_minimum_required(VERSION 3.5)
-project(my_project)
-
-# Pick the C++ standard to compile with.
-# Abseil currently supports C++11, C++14, and C++17.
-set(CMAKE_CXX_STANDARD 11)
-
-add_subdirectory(abseil-cpp)
-
-add_executable(my_exe source.cpp)
-target_link_libraries(my_exe absl::base absl::synchronization absl::strings)
-```
-
-### Running Abseil Tests with CMake
-
-Use the `-DABSL_RUN_TESTS=ON` flag to run Abseil tests.  Note that if the `-DBUILD_TESTING=OFF` flag is passed then Abseil tests will not be run.
-
-You will need to provide Abseil with a Googletest dependency.  There are two
-options for how to do this:
-
-* Use `-DABSL_USE_GOOGLETEST_HEAD`.  This will automatically download the latest
-Googletest source into the build directory at configure time.  Googletest will
-then be compiled directly alongside Abseil's tests.
-* Manually integrate Googletest with your build.  See
-https://github.com/google/googletest/blob/master/googletest/README.md#using-cmake
-for more information on using Googletest in a CMake project.
-
-For example, to run just the Abseil tests, you could use this script:
-
-```
-cd path/to/abseil-cpp
-mkdir build
-cd build
-cmake -DABSL_USE_GOOGLETEST_HEAD=ON -DABSL_RUN_TESTS=ON ..
-make -j
-ctest
-```
-
-Currently, we only run our tests with CMake in a Linux environment, but we are
-working on the rest of our supported platforms. See
-https://github.com/abseil/abseil-cpp/projects/1 and
-https://github.com/abseil/abseil-cpp/issues/109 for more information.
-
-### Available Abseil CMake Public Targets
-
-Here's a non-exhaustive list of Abseil CMake public targets:
-
-```cmake
-absl::algorithm
-absl::base
-absl::debugging
-absl::flat_hash_map
-absl::flags
-absl::memory
-absl::meta
-absl::numeric
-absl::random_random
-absl::strings
-absl::synchronization
-absl::time
-absl::utility
