Camera module v1.3 on OpenWrt 19.07

Hello firends...
I compiled the OpenWrt image after a week of learning;) and it works;)
And now I would like to start the RaspiCamv1.3 webcam.
I found the kmod-video-bcm2835 package, I marked all the gstreamer packages;) but I don't know what to do next, when I try to run, I get the message:

root @ OpenWrt: ~ # raspivid -t 0 -hf -n -h 480 -w 640 -fps 15 -o - | nc -l -p 5001
-ash: raspivid: not found
BusyBox v1.30.1 () multi-call binary.

Usage: nc [IPADDR PORT]

Open a pipe to IP: PORT
root @ OpenWrt: ~ #

I found the topic @ Plonk34 in the forum archive but unfortunately I can't transfer it to version 19.07
Can anyone help me run this on raspi3b + ?? Thank you for your help...

Your link talks about a raspicam package. Kernel modules don't come with executable binaries; so unless you installed something that provides raspivid it won't be there.
