Link the "The runtime single dynamic libraries (SDL) library" of Intel MKL

[Sen Jia]

When I run Gadgetron on Ubuntu, I suddenly encountered the following error that stop the running of Gadgetron (gtplus gadget & toolbox):

" MKL function load error: cpu specific dynamic library is not loaded. "

This was a unexpected and strange situation which was not occurring and reproduced on another Gadgetron machine in our lab. 

The solution was based on:

https://software.intel.com/en-us/articles/a-new-linking-model-single-dynamic-library-mkl_rt-since-intel-mkl-103

https://software.intel.com/en-us/articles/intel-math-kernel-library-intel-mkl-linkage-and-distribution-quick-reference-guide 

I changed the FindMKL.cmake, and added the following line:

SET(MKL_LIBRARIES ${MKL_LIBRARIES} libmkl_rt.so)

to link libmkl_rt.so (there was no libmkl_rt.a).

My experience with MKL is that it can work with gadgetron with either explicitly listing required libraries as suggested in MKL linkage advisor https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor

Or, it can work with MKL dynamic linkage libmkl_rt.so, if a single dynamic library is preferred..

In either way, the /opt/intel/mkl/lib/intel64 and /opt/intel/compiler/lib/intel64 should be in the LD_LIBRARY_PATH for gadgetron to find MKL.

I am on mkl l1.2 and ubuntu 14.04.
