#include<cilk/cilk.h> not found

[ghost]

Hey everyone after installing cilkplus. I try to compile a simple program of Fibonacci. But there is an error which says that "#include<cilk/cilk.h>" not found.
the cilkplus runtime library file libcilkrts is not there which contains the cilk.h header file.
Can anyone help me to add the library file libcilkrts with LLCM/Clang.
Thank you.

What OS are you running, and what is the exact command and error you are seeing?

Have you set up the compiler's include paths (see the "Using" section on cilkplus.github.io)?
