How do I statically link an openmp library using intel's icl.exe compiler on windows

Take the toy code

#include <stdlib.h>

#include "omp.h"

int main()
{
    #pragma omp parallel
    {}
    return EXIT_SUCCESS;
}

I would like to do something like:

icl.exe main.c /Qopenmp /Qopenmp-link=static /MT

This help page contains instructions for statically linking in Linux and Mac. But for windows it cryptically says "none". Does this mean static linking is impossible? Or does it mean some alternative procedure is necessary. What is that procedure?

We don't have option to statically link an OpenMP as I think Microsoft doesn't support it neither.

I don't think it's possible because we don't have a static library to begin with.

I am also interested in having a C++ static library for OpenMP for Windows.

 

There is a static openmp library provided for MacOS and Linux in the current oneAPI distribution.

 

And, certainly Microsoft allows static library linking.

 

So, why does Intel not provide a static openmp library for Windows?

 

This is the real question from the original post.  So far, no one has given a technical answer as to why this is not possible.

 

And if there is no technical obstacle unique to Windows (which many people believe that there is not one), then Intel customers like myself would like to have such a static library for OpenMP.  (GPU-offload is not a concern to many developers who use OpenMP, so that should not be an inhibiting factor.)
