Using opencv on risc-v processors with zephyr rtos

As for my understanding present open-CV compilation is RISC-V based Linux systems.

But i want to compile as a static library of open-CV which will integrate with zephyr RTOS.

since my system runs only on zephyr without any platform(like Linux)

when i am trying to integrate with zephyr RTOS, some libraries are missing

example : not able to include mutex.h because in zephyr (mutex.h header is in the name of std_mutex.h)
