# A simple Makefile for KLU, which relies on cmake to do the
# actual build.  All the work is done in cmake so this Makefile is just for
# convenience.

# To compile with an alternate compiler:
#
#       make CC=gcc CXX=g++
#
# To compile/install for system-wide usage:
#
#       make
#       sudo make install
#
# To compile/install for local usage (SuiteSparse/lib and SuiteSparse/include):
#
#       make local
#       make install
#
# To clean up the files:
#
#       make clean
