// This file contains a map to redirect dependencies towards sysprop_library.
// As sysprop_library has to support both Java and C++, sysprop_library internally
// generates cc_library and java_library. For example, the following sysprop_library
//
// sysprop_library {
// name: "foo",
// }
//
// will internally generate with prefix "lib"
//
// cc_library {
// name: "libfoo",
// }
//
// When a cc module links against "foo", build system will redirect the
// dependency to "libfoo". To do that, SyspropMutator gathers all sysprop_library,
// records their cc implementation library names to a map. The map will be used in
// cc.Module.DepsMutator.
