That looks way to platform specific...

include_directories(${MKL_INCLUDE_DIRS})
target_link_libraries(<module>
${MKL_LIBRARIES}/libmkl_solver_lp64_sequential.a
${MKL_LIBRARIES}/libmkl_core.a )

Or, this would be even better:

find_library( MSOLVE mkl_solver_lp64_sequential HINTS ${MKL_LIBRARIES})
find_library( MKLCORE mkl_core HINTS ${MKL_LIBRARIES})
target_link_libraries(<module>  ${MSOLVE} ${MKLCORE}

You should find out where the symbol is defined...

nm -PA ${MKL_LIBRARIES}/*.a | grep dtrnlsp_init
