I use this function. Even without the $(info) it probably requires 3.81.
# logical not
not = $(if $(strip $(1)),,t)
# find-files-matching-extension:
# $(1)=subdir of $(CURDIR) to begin search
# $(2)=extension patterns
# $(3)=private recursive state variable (don't set)
find-files-matching-extension = \
$(strip \
$(if $(call not,$(3)), \
$(eval .thisdir := $(CURDIR)/$(1)) \
, \
$(eval .thisdir := $(1)) \
) \
$(eval .thesefiles := $(wildcard $(.thisdir)/*)) \
$(foreach .thisfile,$(.thesefiles), \
$(eval .subdir := $(wildcard $(.thisfile)/*)) \
$(if $(.subdir), \
$(call find-files-matching-extension,$(.thisfile),$(2),t) \
, \
$(filter $(2),$(.thisfile)) \
) \
) \
)
$(info $(call find-files-matching-extension,.,%.cc))
Enjoy
