Abseil comes with a CMake build script (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.
For API/ABI compatibility reasons, we strongly recommend building Abseil in a subdirectory of your project or as an embedded dependency.
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)
If you haven‘t done so already, integrate the Abseil dependency CCTZ into your CMake project. Consequently, the target ‘cctz’ needs to be declared in your CMake project before including Abseil.
Note: If you want to build the Abseil tests, you’ll also need Google Test. To disable Abseil tests, you have to pass -DBUILD_TESTING=OFF when configuring your project with CMake.
Download Abseil and copy it into a subdirectory in your CMake project or add Abseil as a git submodule in your CMake project.
You can then use the CMake command add_subdirectory() to include Abseil directly in your CMake project. In addition, it's possible to customize the name of the cctz target with the -DABSL_CCTZ_TARGET=*my_cctz* option.
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 project file using Abseil.
