Previously, there was no check performed on features of plugins if these specify GStreamer plugins. This commit adds that, and ensures that the plugins and pkg-config targets are skipped if no outputs are to be generated (this is already done for examples). Closes #369 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/merge_requests/1303>
