NOTE: `cc-rs` only supports a fixed set of targets when not in a build script. - If adding a new target, you will need to fork of `cc-rs` until the target has landed on nightly and the auto-generated list has been updated. See also the `rustc` dev guide on adding a new target: https://rustc-dev-guide.rust-lang.org/building/new-target.html - If using a custom target, prefer to upstream it to `rustc` if possible, otherwise open an issue with `cc-rs`: https://github.com/rust-lang/cc-rs/issues/new GnuClangzig_ccSome()PoisonErrorIOErrorEnvVarNotFoundToolExecErrorToolNotFoundInvalidArgumentToolFamilyMacroNotFoundInvalidTargetUnknownTargetInvalidFlagfailed to write whole bufferdescription() is deprecated; use DisplayEmptyInvalidDigitPosOverflowNegOverflowParseIntErrorLayoutError
