# Makefile for iterativeSystemSolveLegacy example
#
# To compile this example, please ensure that some extra environment
# variables are defined. An example configuration may look like the following:
#
#     export INTEL_ROOT=/opt/intel/composerxe-2011.3.174
#     export INTEL_LIB_PATH_32=$INTEL_ROOT/compiler/lib/ia32
#     export INTEL_LIB_PATH_64=$INTEL_ROOT/compiler/lib/intel64
#
#     export MKL_ROOT=$INTEL_ROOT/mkl
#     export MKL_INC_PATH=$MKL_ROOT/include
#     export MKL_LIB_PATH_32=$MKL_ROOT/lib/ia32
#     export MKL_LIB_PATH_64=$MKL_ROOT/lib/intel64
#
# Due to recent changes in Intel's MKL distribution, this example only supports
# MKL 10.3 or greater.  If you do not have MKL, append 'mkl=0' to your command
# line when calling make.  Similarly, to compile without cuda, use 'cuda=0'
#
# e.g.   make build32 mkl=0
# e.g.   make build32 cuda=0
# e.g.   make build32 mkl=0 cuda=0
