Explicit value for parallel_read_safe setting of sphinxcontrib-cmakedomain package
parallel_read_safe is currently undefined for the sphinxcontrib-cmakedomain package as far as I can tell. https://www.sphinx-doc.org/en/master/extdev/index.html#extension-metadata
This means that it will default to false. So could this be explicitly set, and if so is there anything preventing it from being set to true?
