[Trilinos-Users] Installing with Intel MKL

[Mark Hoemmen]

Here are the relevant lines from a do-configure script I have that uses Intel's MKL.  First set MKL_LIB in your shell with the path to the MKL libraries, and replace the TPL_BLAS_LIBRARIES link line with an appropriate line for your use or non-use of the multithreaded MKL.

-D TPL_ENABLE_BLAS:BOOL=ON \
-D TPL_BLAS_LIBRARIES:STRING="-L$MKL_LIB -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5" \
-D TPL_ENABLE_LAPACK:BOOL=ON \
-D TPL_LAPACK_LIBRARIES:STRING="-L$MKL_LIB -lmkl_lapack" \

This is for a static-libraries build, if I recall correctly.
