+## Abseil CMake build instructions
+
+
+### Recommended usage : incorporate Abseil into an  CMake project
+
+  For API / ABI compatibility reasons, it is recommended to build
+  and use abseil in a subdirectory of your project or as an embedded
+  dependency
+
+  This is similar to the recommended usage of the googletest framework
+  ( https://github.com/google/googletest/blob/master/googletest/README.md )
+
+  Build and use step-by-step
+
+
+  1- Download abseil and copy it in a sub-directory in your project.
+      or add abseil as a git-submodule in your project
+
+  2- If not done yet, download and copy in your project the two dependencies of
+      abseil `cctz` and `googletest`
+
+    * cctz  https://github.com/google/cctz
+    * googletest https://github.com/google/googletest
+
+  3- You can then use the cmake command `add_subdirectory()` to include
+  abseil directly and use the abseil targets in your project.
+
+    Note: Abseil requires CCTZ and the googletest framework. Consequently,
+    the targets  `gtest`, `gtest_main`, `gmock` and `cctz` need
+    to be declared in your project before including abseil with `add_subdirectory`.
+
+
+  4- Add the absl:: target you wish to use to the `target_link_libraries()`
+    section of your executable or of your library
+
+
+      Here is a short CMakeLists.txt example of a possible project file
+      using abseil
+
+      cmake_minimum_required(VERSION 2.8.12)
+      project(my_project)
+
+      set(CMAKE_CXX_FLAGS "-std=c++11 -stdlib=libc++ ${CMAKE_CXX_FLAGS}")
+
+      add_subdirectory(googletest)
+      add_subdirectory(cctz)
+      add_subdirectory(abseil-cpp)
+
+      add_executable(my_exe source.cpp)
+      target_link_libraries(my_exe absl::base absl::synchronization absl::strings)
+
+
+You will need to create your own CMake files for cctz until https://github.com/google/cctz/pull/54 lands.  As of this writing, that pull request requires -DBUILD_TESTING=OFF as it doesn't correctly export cctz's dependency on Google Benchmark.
+    
+    You will find here a non exhaustive list of absl public targets
+
+      absl::base
+      absl::algorithm
+      absl::container
+      absl::debugging
+      absl::memory
+      absl::meta
+      absl::numeric
+      absl::strings
+      absl::synchronization
+      absl::time
+      absl::utility
+
+
