If one is building a non-bundle product, the following flags should be added to cpp.linkerFlags:

["-sectcreate", "__TEXT", "__info_plist", "path/to/Info.plist"]

The basic workflow would be the same as for bundle products except that output Info.plist file could be placed in, say, <builddir>/.intermediate/<productname>/Info.plist instead of the usual <builddir>/<productname>.app/Contents/Info.plist.

This warrants the use of a new property: (bool)embedInfoPlist.

Documentation for this property would be as follows:

Whether to create a section in the product's executable containing the processed Info.plist file. Does not apply to bundles.

Default: product.type.contains("application")

This mirrors the Xcode setting CREATE_INFOPLIST_SECTION_IN_BINARY.
