# A simple Makefile for LAGraph, 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 and run the tests:
#
#       make
#       make test
#
# To compile with an alternate compiler:
#
#       make CC=gcc CXX=g++
#
# To compile/install for system-wide usage (typically in /usr/local):
#
#       make
#       sudo make install
#
# To compile/install for elsewhere (for example, in /home/me/mystuff/lib
# and /home/me/mystuff/include), do not use this Makefile.  Instead, do:
#
#       cd build
#       cmake -DCMAKE_INSTALL_PREFIX="/home/me/mystuff" ..
#       make
#       make install
#
# To clean up the files:
#
#       make clean
#
# To uninstall:
#
#       make uninstall
#
# To compile and run test coverage: use "make cov".  Next, open your browser to
# your local file, LAGraph/build/test_coverage/index.html.  Be sure to do "make
# clean" afterwards, and then "make" to compile without test coverage.
