PyO3 provides Rust bindings for Python, including tools for creating native Python extension modules. Running and interacting with Python code from a Rust binary is also supported. This class sets up the cross-compilation environment. Export PYO3_CROSS, PYO3_CROSS_LIB_DIR, PYO3_CROSS_INCLUDE_DIR and CARGO_BUILD_TARGET to inform tools like setuptools-rust we are cross-compiling. Export RUSTFLAGS so cargo can find 'std' and 'core' for target Dynamically generate PyO3 config file and export PYO3_CONFIG_FILE absolute path. This is the trick that finally made pyo3 work.
