#
#  ======== makefile ========
#
#  This "top level" make file can be used with GNU's make utility
#  to (re)build XDAS examples
#
#  To (re)build from scratch type the following:
#	gmake clean
#	gmake 
#
#  subdirs = 	list of all sub-directories containing a makefile
#  submake = 	a definition to perform a sub-make with an embedded new
#		line.  Do not remove the blank line!  This line is required
#		to ensure that the $(foreach ...) function used below 
#		generates a separate line for each sub-directory
#  makeall = 	recursive sub-make for each directory defined in $(subdirs)
#

subdirs = $(dir $(wildcard */makefile))

define submake

$(MAKE) -C $(var) $@
endef

makeall = $(foreach var,$(subdirs),$(submake))

all:
	@echo making all files in the directories $(subdirs) ...
	+@$(makeall)

clean::
	@echo "cleaning $(subdirs) ..."
	@$(makeall)
