Changing executable and bundle names based on --example argument

[woodworthkyle]

I’m building a library that contains examples, which I run with the --example argument. I’m specifically using bundle to build Mac Catalyst bundles.

# Build
cargo +nightly build -Z build-std --target x86_64-apple-ios-macabi --example simple
# Bundle
CARGO_BUNDLE_SKIP_BUILD=1 cargo bundle --target x86_64-apple-ios-macabi --example simple

This yields a <package_name>.app bundle instead of a <example_name>.app bundle. The executable comes out as <package_name> but the CFBundleExecutable entry in the Info.plist comes out as <example_name>. The mismatch between the Info.plist and executable name does not allow the bundle to launch properly.

Is there a way to specify the bundle name and executable name based on other build options like the --example argument?
