Subject: [PATCH] fix: add lib64 to link search path for Fedora/RHEL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On distros where cmake's GNUInstallDirs defaults CMAKE_INSTALL_LIBDIR to lib64, the vendored opus build succeeds but linking fails because the search path only includes lib/. Adding lib64 as an additional search path fixes this — non-existent -L paths are silently ignored by the linker, so no behavioral change on platforms that use lib/.
