# Native Simulator (NSI) Makefile.
# It builds the simulator runner itself, and produces the final
# Linux executable by linking it to the the embedded cpu library
# By default all the build output is placed under the _build folder, but the user can override it
# setting the NSI_BUILD_PATH
#
# The caller can provide an optional configuration file and point to it with NSI_CONFIG_FILE
# See "Configurable/user overridible variables" below.
#
# By default only the core of the runner will be built, but the caller can set NSI_NATIVE
# to also build the components in native/src/
