* Add `setuptools_scm` for dynamic zero-config Python versioning
This removes the need for manually bumping versions in the Python
bindings.
For the wheel uploads, the correct semver version is inferred in the case
of tagged commits, which is exactly the case in GitHub CI.
The docs were updated to reflect the changes in the release workflow.
* Add separate version variable and module, use PEP484-compliant exports
This is the best practice mentioned in the `setuptools_scm` docs, see
https://setuptools-scm.readthedocs.io/en/latest/usage/#version-at-runtime.
* Migrate to bzlmod
* Update Python version to PY3, as indicated by the actual source file.
* Migrate more libraries & first draft of direct pywheel rule usage in Bazel
* Integrate with nanobind and libpfm
* Make Python toolchain a dev dependency
* Undo py_wheel usage until later
* Added support for bzlmod for C++ parts of google_benchmark.
* Make //tools:all buildable with --enable_bzlmod

* Add possibility to ask for libbenchmark version number (#1004)
Add a header which holds the current major, minor, and
patch number of the library. The header is auto generated
by CMake.
* Do not generate unused functions (#1004)
* Add support for version number in bazel (#1004)
* Fix clang format #1004
* Fix more clang format problems (#1004)
* Use git version feature of cmake to determine current lib version
* Rename version_config header to version
* Bake git version into bazel build
* Use same input config header as in cmake for version.h
* Adapt the releasing.md to include versioning in bazel
* 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
