calebzulawski added a comment. If `SDKROOT` is set or `-isysroot` is passed, `xcrun` won't be called so there is no regression for existing use cases like CMake. Additionally, if `xcrun` isn't found, no error is emitted. I also added the `--no-detect-xcode` flag based on similar feedback that it may not always be desirable.
Better diagnostics would certainly be helpful, but for my particular use case, a diagnostic wouldn't be sufficient. I am creating a set of default configuration files for cross compilation, e.g. `aarch64-android-linux-clang++.cfg` contains `-isysroot` with a known fixed path. This allows me to pass `clang++ --target=aarch64-android-linux` with no additional flags to cross compile. I would like to do the same for Apple targets (not with the system compiler), but since the path is not fixed I cannot embed `-isysroot`. If there is enough opposition to this being default behavior, I'd be open to it being opt-in with something like `--detect-xcode`.
