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.

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.
