* Fix dependency typo and unpin cibuildwheel version in wheel building action
* Move to monolithic build jobs, restrict to x64 architectures
As of this commit, all wheel building jobs complete on GitHub Actions. Since some platform-specific options had to be set to fix different types of build problems underway, the build job matrix was unrolled.
Still left TODO:
* Wheel testing after build (running the Python bindings test)
* Emulating bazel on other architectures to build aarch64/i686/ppc64le
* Enabling Win32 (this fails due to linker errors).
* Add binding test commands for all wheels, set macOSX deployment target to 10.9
* Add instructions for updating Python __version__ variable before release creation
* cmake: fix handling the case where `git describe` fails
* cmake: fix version recorded in releases
If downloaded as a tarball release, there will be no info from git
to determine the release, so it ends up v0.0.0. If that's the case,
we'll now use the release specified in the project() command,
which needs to be updated for each new release.
* cmake: add `--tags` to `git describe`
That way, lightweight tags will also be taken into account, which should
never hurt, but it'll help in cases where, for some mysterious reason or
other, annotated tags don't make it into a clone.
* update releasing.md
