This commit contains a fix for macOS ARM64 wheel buils in Google Benchmark's wheel building CI.
Previously, while `cibuildwheel` itself properly identified the need for cross-compilations and produced valid ARM platform wheels, the included shared library containing the Python bindings
built by `bazel` was built for x86, resulting in immediate errors upon import.
To fix this, logic was added to the setup.py file that adds the "--cpu=darwin_arm64" and "--macos_cpus=arm64" switches to the `bazel build` command if
1) The current system platform is macOS Darwin running on the x86_64 architecture, and
2) The ARCHFLAGS environment variable, set by wheel build systems like conda and cibuildwheel, contains the tag "arm64".
This way, bazel correctly sets the target CPU to ARM64, and produces functional wheels for the macOS ARM line of CPUs.
* 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
* Fix setup.py and reformat
* Bind benchmark
* Add benchmark option to Python
* Add Python examples for range, complexity, and thread
* Remove invalid multithreading in Python
* Bump Python bindings version to 0.2.0
