"nvdewarper" not found after replacing files

[jayben-2022]

Hi,

I had my default nvdewarper working with default config file.
In order to have more projection types, I replaced both the files (libnvdgst_dewarper.so & nvds_dewarper_meta.h) as instructed.
After replacing the files, I am getting an error (Warning: erroneous pipeline: no element "nvdewarper").
By replacing with the default files, i am getting the exact same error again.
Kindly, suggest a solution for the above mentioned issue.
