How to disable openMP with Matlab Coder?

I want to use Matlab Coder to compile a function that will not profit much from multithreading. Although I use

codegen -O disable:openmp

the resulting C source includes omp.h and tries to find vcompXXX.dll when run.

How can I switch off OpenMP use completely?

Try:

    cfg = coder.config('dll');
    cfg.EnableOpenMP = false;
    codegen -config cfg ...

Or if you are using the Matlab Coder GUI, once you reach the Generate Code stage click on "More Settings"

Then go to All Settings --> Advanced --> Enable OpenMP library if possible --> No

In MATLABT R2021b version, even I disable the OpenMP libarart if possible, the omp.h file is still included in the header files.
