Applications that use mkl need to choose the right set of libraries and command line options as explained by https://software.intel.com/content/www/us/en/develop/tools/oneapi/components/onemkl/link-line-advisor.html

The current intel-oneapi-mkl does not provide any compile options and assumes sequential, ilp64.
Similar to the intel-mkl package, we need to provide these options as part of the spack package via variants.

I talked to @jasukhar and @NadyaTen and they recommended that we use the link line tool rather than hard code the libraries into the spack package.

We need to decide which variants to provide and whether to use the command line tool/
