[libc++][CMake] Refactor how we link against system libraries

Authored by ldionne on Apr 22 2019, 10:12 AM.



Instead of populating the global LIBCXX_LIBRARIES, we use the link-time
dependency management built into CMake to propagate link flags. This
leads to a cleaner and easier-to-follow build.

This is now handled by CMake automatically, because benchmarks link against cxx_shared or cxx_static, and those have PUBLIC link dependencies.

This is awesome!

Can we get rid of add_library_flags and add_library_flags_if now?
