Configuration Options

Field	Type
src	str | None   directory within src dir or .  which aliases the package being built. e.g. package_a -> src/package_a_lib   src = "package_a"
directives	directives to cython (see cython docs)
compile_args	str or { platforms = ["*"] | "*", arg = str }
includes	list str
includes_{package}	{ pkg = str, include = str, libraries = str| None, library_dirs = str | None , required_call = str | None }   where all fields, but pkg, are attributes in the type of callable() -> list[str] | str | list[str] | str
includes_numpy | includes_pyarrow	bool  3rd party named imports. must have the respective opt in dependencies
retain_intermediate_artifacts	bool = False   whether to keep .c | .cpp files
parallel	bool = False  if parallel, add openmp headers  important: if using macos, you need the homebrew llvm vs apple's llvm in order to pass -fopenmp to clang compiler
compiler	compiler used at build-time. if msvc (Microsoft Visual Studio), /openmp is used as argument to compile instead of -fopenmp  when parallel = true
** kwargs	keyword = value pair arguments to pass to the extension module when building
