Hi,

When compiling the example device provider I am unable to receive messages concerning any non v4l2 devices.
In fact the exampledeviceprovider is not even loaded according to debug output.

Source for exampledeviceprovider:
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/blob/master/tests/examples/device-provider/example-device-provider.c

Cut output when running tests with `--gst-debug-level=4`. These are the only provider loaded.

System is a Debian testing with GStreamer 1.18.3.

Are there any additional ways to get information as to why my custom provider is not used?
