How to release

Make sure you're on main and synced to HEAD
Ensure the project builds and tests run (sanity check only, obviously)
- parallel -j0 exec ::: test/*_test can help ensure everything at least passes
Prepare release notes
- git log $(git describe --abbrev=0 --tags)..HEAD gives you the list of commits between the last annotated tag and HEAD
- Pick the most interesting.
Create one last commit that updates the version saved in CMakeLists.txt to the release version you're creating. (This version will be used if benchmark is installed from the archive you'll be creating in the next step.)
```
project (benchmark VERSION 1.5.3 LANGUAGES CXX)
```
Create a release through github's interface
- Note this will create a lightweight tag.
- Update this to an annotated tag:
  - git pull --tags
  - git tag -a -f <tag> <tag>
  - git push --force --tags origin
