Subject: Set the FOLDER property for Abseil targets.

https://cmake.org/cmake/help/v3.0/prop_tgt/FOLDER.html
This only affects IDEs and will further only take effect if
  set_property(GLOBAL PROPERTY USE_FOLDERS ON)
is set in the main CMakeLists.txt of the project.

I found using this quite helpful when adding Abseil to larger CMake
projects.
