Subject: [PATCH] Silence qdoc warnings from std::filesystem
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We change the declaration of the new APIs using std::filesystem::path for
qdoc runs, and need to forward declare it consistently for qdoc builds to
avoid a flood of clang warnings when building documentation.
