Hi,

I am trying to use the MKL platform to run itensor. But I cannot find the two libraries libiomp5 & libpthread as stated in the option.mk file by

```
BLAS_LAPACK_LIBFLAGS=-L/opt/intel/mkl/lib/intel64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_rt -lmkl_core -liomp5 -lpthread
```

What I can see in the MKL library is

```
