Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

Answer: Issue: The build failed because does not find the  correct headers where std::unique_ptr is defined.
Resolution: Edit  third_party/skia/experimental/rust_png/ffi/FFI.h and add #include <memory>  at the very top of the file.
