// Given the following dependency graph:

//           main
//            |
//          FooClient (.swiftinterface)
//            |                 \
//          Foo(.swiftmodule)   Dart (.pcm)
//
// Given that 'Foo.swiftmodule' is built with a bridging header which imports 'X.h' ('X' clang module)
// We expect that 'Foo' will have a dependency on module 'X', and the scanner will ensure that 'FooClient' is built
// with the modulemap file for 'X' as an explicit input. 'Dart' Clang module however, must not result in an
// explicitly-specified modulemap file because no headers of this module will be ingested into the Swift
// compiler.
