feat: support MATURIN_PGO env var to activate --pgo#3271
Merged
Conversation
Allow enabling Profile-Guided Optimization via the MATURIN_PGO environment variable in `maturin build`, `maturin publish`, `maturin develop` and PEP 517 builds (e.g. `pip install .`). Values are parsed leniently: `0`, `false`, `no`, `off` or an empty string disable it, anything else enables it. The pep517 subcommands also accept an explicit `--pgo` flag, so it can be passed through MATURIN_PEP517_ARGS as well.
