I tested installing rapidyaml from my GitHub fork and this fixes the issue with installing rapidyaml. I'm using poetry and this is what I did:

# ... truncated

[build-system]
requires = ["poetry-core", "swig"]
build-backend = "poetry.core.masonry.api"

# ... truncated

[tool.poetry.dependencies]

# rapidyaml = { git = "https://github.com/biojppm/rapidyaml.git", rev = "a5eefff1f87de8f1ec85cea34bed361d40868631" }
rapidyaml = { git = "https://github.com/mboutet/rapidyaml.git", rev = "9fffec0876e571784e2d98b1c75c0639a8381806" }

# ... truncated
