Hello Nilesh,
The repository is actually not clean and some file should not be compiled.
There are cmake files in each directory from npa-vee-rw612/bsp/vee/port at main · nxp-mcuxpresso/npa-vee-rw612 · GitHub, for example ui/microej_ui.cmake. You can look at them to know which files to compile.
Sorry for this inconvenience.
Regards,
Alexis
