does not set GST_PLUGIN_PATH

Hi Jim,

This shouldn't be happening, could you please file an issue about this

Can you try doing:

./ --only-environment >

And see if that sets GST_PLUGIN_PATH? Does the set value match the
value in

Once we've figured out the issue, we can either fix the issue itself,
or work around it by relying on the plugin loader's recursive nature
and only adding top-level directories.
