= WebKitGTK+ Dependencies =

This is the list of direct dependencies of WebKitGTK+, the ones we check when building. There are also indirect dependencies as required by the direct dependencies (for example cairo requires libpixman). There's a set of required dependencies and some others are optional, but required to enabled some features (for example you need GStreamer to have audio/video support).

We have a policy of not bumping minimum requirements of the dependencies unless it's really necessary (important security issues, crashes, etc.), however for some of the dependencies we encourage to use a newer version, as features will be disabled at build time if you don't have a newer version.
