How to add GStreamer GST_TRACERS plugin to a multimedia image for imx8qxp by using Yocto?

[killedByBugs]

Hi, 

I am using a NXP i.MX8qxp mek board. I made a Linux image by using Yocto with NXP's BSP. GStreamer was built in the multimedia image. However, I found that GST_TRACERS plugin is not built in when I try commands like

GST_DEBUG="GST_TRACER:7" GST_TRACERS=latency gst-launch-1.0 ...

Nothing shows about latency. (It said no such plugin when I tried the command gst-inspect-1.0 GST_TRACER.)
I am not sure why a core plugin is not built. Also, I don't know how to add the GStreamer GST_TRACERS plugin to that Linux image. Can you please let me know how to add this plugin?

Have a try to add IMAGE_INSTALL:append = " gst-shark"
