			# This Makefile is intended to be included in an application Makefile
			# It will append the OBJ variable with objects needed for building with Kokkos
			# It also will produce a KOKKOS_INC and a KOKKOS_LINK variable which must be
			# appended to the compile and link flags in the application Makefile

			# Note that you cannot compile and link at the same time!
			# If you want to include dependencies (i.e. trigger a rebuild
			# of the application object files when Kokkos files change,
			# you can include KOKKOS_HEADERS in your dependency list)

			# This potion of the Makefile defines defaults for sevearl variables
			# they can be overridden on the make commandline
			# or in the application Makefile prior to including this Makefile

			# Build for Debug mode: add debug flags and enable boundschecks within Kokkos

			# use AVX instruction set
			# build for Xeon Phi (MIC)
			# use reduced precision math (sets compiler flags like --fast_math)
