Elemental does not currently take into account the CMake option EL_USE_64BIT_BLAS_INTS when deciding how to build and/or interface to external BLAS libraries such as MKL and OpenBLAS and assumes that the user manually specifies MATH_LIBS. OpenBLAS builds could be handled via passing a definition of INTERFACE64 into the ExternalProject_Add command [1], and MKL could be handled via adding the -DMKL_ILP64 definition before including mkl.h.

Does this require code change within Elemental or just CMake?
