MemfaultWorker.mk

# A convenience helper makefile that can be used to collect the sources and include
# flags needed for the Memfault SDK based on the components used
#
# USAGE
# If you are using a Make build system, to pick up the Memfault include paths & source
# files needed for a project, you can just add the following lines:
#
# MEMFAULT_SDK_ROOT := <The path to the root of the memfault-firmware-sdk repo>
# MEMFAULT_COMPONENTS := <The SDK components to be used, i.e "core panics util">
# include $(MEMFAULT_SDK_ROOT)/makefiles/MemfaultWorker.mk
# <YOUR_SRC_FILES> += $(MEMFAULT_COMPONENTS_SRCS)
# <YOUR_INCLUDE_PATHS> += $(MEMFAULT_COMPONENTS_INC_FOLDERS)

# A utility to easily assert that a Makefile variable is defined and non-empty
#   Argument 1: The variable to check
#   Argument 2: The error message to display if the variable is not defined
memfault_assert_arg_defined = \
  $(if $(value $(strip $1)),,$(error Undefined $1:$2))
