After dealing with, various problems, it turns out the main 
problem was ndiota with pool.parallel.
https://github.com/aferust/ddcv/blob/main/source/dcv/imgproc/filter.d#L564
```
foreach (row; /*pool.parallel(*/ndiota(input.shape)/*)*/) // 
parallel loop causes a linker error
{
     row.each!(i => calcGradientsImpl(fx[i], fy[i], mag[i], 
orient[i]));
}
```
The parallel loop causes a linker error here?
