#2772: Issues link against Kadath thorns and Intel MKL due to link ordering

 Reporter: tootle
   Status: new
Milestone: 
  Version: 
     Type: bug
 Priority: major
Component: EinsteinToolkit thorn

Comment (by Roland Haas):

How about adding \`$\{FFTW3\_LIBS\}\` to KadathThorn’s LIBS output in detect.sh ? Like HDF5 does:

```
          HDF5_LIB_DIRS="$HDF5_LIB_DIRS $MPI_LIB_DIRS"
          HDF5_INC_DIRS="$HDF5_INC_DIRS $MPI_INC_DIRS"
          HDF5_LIBS="$HDF5_LIBS $MPI_LIBS"
```

That lets you ensure that FFTW3\_LIBS is right after Kadath’s. This should work for static linking. For dynamic linking adding it to `LD` should work. So it’s a cluster specific solution \(at least for `LD`\) but so is this issue you are encountering.
