parallel compilation of subdirs

[Peng Yu]

Hi,

I have the following Makefile, which will go to each subdir and call
"make". But "make" in each subdir can not be executed in parallel
(when I "make" in the parent dir with -j option). I'm wondering if
there is any way to enable parallel compilation.

Thanks,
Peng


#######Makefile
SUBDIRS = $(filter-out Makefile%, $(wildcard *))

.PHONY: all

all:
        @for dir in $(filter-out backup, $(SUBDIRS)); do \
        $(MAKE) -C $$dir; \
        done
