Subject: Enable CMake support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Install Abseil’s CMake support files. Some of these files are
autogenerated, and the generator produces files with a googletest
dependency if Abseil is built with unit tests enabled; to prevent this,
turn off unit tests.
