Subject: [PATCH] CMake: Add an option to disable each sound backend.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

They are already disabled when the libraries can’t be found, this only
helps people who want to build without them despite having them
installed, for example to provide a package to someone else.
