Unable to use plugin after build and install

I built and installed the plugin following the directions, however trying any of the commands results in the error

`No such element or plugin 'icamerasrc'`

I've tried rebuilding it and reinstalling it to no avail. gst-inspect-1.0 doesn't show the plugin as installed.

I am installing this on a tigerlake system with IPU6, the drivers, hal, and bins are all installed, as well as ll prerequisites for this repo.
