777928035dbcbf39f361eb7d10dc3696822f692f by Jon Cohen <cohenjon@google.com>:

Add install rules for Abseil CMake.

These are attempted to be limited to in-project installation.  This serves two purposes -- first it's morally the same as using Abseil in-source, except you don't have to rebuild us every time.  Second, the presence of an install rule makes life massively simpler for package manager maintainers.

Currently this doesn't install absl tests or testonly libraries.  This can be added in a follow-up patch.

Fixes #38, Fixes #80, Closes #182
