Building additional custom targets accompanying library or program
==================================================================
There are cases when it is important to build additional targets
besides standard files built for library or program. Of course there
is no problem with writing specific make rules for commands that
generate those target files but for them to be built a proper
dependency must be specified. To achieve it those additional targets
should be added to 'CUSTOM_TARGET_DEPS' variable like e.g. in
iwl_firmware library from dde_linux repository:
! CUSTOM_TARGET_DEPS += $(addprefix $(BIN_DIR)/,$(IMAGES))
