[Q] Help needed in compiling CWM recovery topic

I'm trying to build CWM for a device which was recently launched and not much work has been done on it. I tried downloading CM-12.0 repo multiple times and on multiple machines but I still get the following error everytime I try using lunch command (p897a21 is the name of the device and the actual product name is ZTE Grand S2 S251)

Code:

---

build/core/product_config.mk:234: *** Can not locate config makefile for product "full_p897a21".  Stop.
Device p897a21 not found. Attempting to retrieve device repository from CyanogenMod Github (http ://github. [new account on xda]xom/CyanogenMod).
Repository for p897a21 not found in the CyanogenMod Github repository list. If this is in error, you may need to manually add it to your local_manifests/roomservice.xml.
build/core/product_config.mk:234: *** Can not locate config makefile for product "full_p897a21".  Stop.

The same error even occurs when I try building CWM for any other device
It tries to locate the device config on official cyanogenmod sources but this device doesn't have any vendor/device files on github. AFAIK building only CWM doesn't require those two folders so I'm confused as to where I'm making a mistake.
Any help is appreciated .
Thanks,
