Bash: trtexec: command not found

Description

I tried to build trtexec in .../TensorRT/samples. I followed this git link for building the sample but it didn’t work. It looks like it’s not a valid command with the message :
bash: trtexec: command not found

I think the building steps are similar and and intuitive with make commad. But I am not sure why I got the error after make the trtexec and I cannot use the trtexec command.

Which Jetpack version you are currently using?
Can you try to reinstall the latest Jetpack?

It should be located in /usr/src/tensorrt/bin or /opt/tensorrt/bin

Thanks
