# simple Makefile for GraphBLAS, relies on cmake to do the actual build.  Use
# the CMAKE_OPTIONS argument to this Makefile to pass options to cmake.
# For example, to compile with 40 threads, use:
#
#       make JOBS=40
#
# To compile without using Google's cpu_features package, using 40 threads:
#
#       make CMAKE_OPTIONS='-DGBNCPUFEAT=1' JOBS=40
#
# To use multiple options, separate them by a space.  For example, to build
# just the library but not cpu_features, and to enable AVX2 but not AVX512F:
#
#       make CMAKE_OPTIONS='-DGBNCPUFEAT=1 -DGBAVX2=1' JOBS=40

JOBS ?= 8
