请教下，如何才能一次性编译erlang代码哇
在erlang 项目中，src下面有很多的包，src下写一个makefile，然后每个包下也有makefile，但是执行#erl -make命令不能一次性全部编译，只能一个包一个包的erl -make，有什么方法能一次性编译吗

src下面的makefile内容如下
include ../support/include.mk all:
(cd core;$(MAKE))
(cd xmpp;$(MAKE))
(cd nagios;$(MAKE))
(cd disco;$(MAKE))
(cd disco/mods;$(MAKE))
(cd mit;$(MAKE))
(cd elog;$(MAKE))
(cd errdb;$(MAKE))
(cd evabus;$(MAKE))
(cd misc;$(MAKE))
(cd mochiweb;$(MAKE))
(cd monet;$(MAKE))
(cd monet/monitors;$(MAKE))
(cd mysql;$(MAKE))
(cd sesnmp;$(MAKE))
(cd trapd;$(MAKE))
(cd opengoss;$(MAKE)) clean:
(cd core;$(MAKE) clean)
(cd xmpp;$(MAKE) clean)
(cd nagios;$(MAKE) clean)
(cd disco;$(MAKE) clean)
(cd disco/mods;$(MAKE) clean)
(cd mit;$(MAKE) clean)
(cd elog;$(MAKE) clean)
(cd errdb;$(MAKE) clean)
(cd evabus;$(MAKE) clean)
(cd misc;$(MAKE) clean)
(cd mochiweb;$(MAKE) clean)
(cd monet;$(MAKE) clean)
(cd monet/monitors;$(MAKE) clean)
(cd mysql;$(MAKE) clean)
(cd sesnmp;$(MAKE) clean)
(cd trapd;$(MAKE) clean)
(cd opengoss;$(MAKE) clean)

各个包的makefile如下
include ../../support/include.mk
all: $(EBIN_FILES) debug:
$(MAKE) DEBUG=-DDEBUG clean:
rm -rf $(EBIN_FILES)

项目src下的结构

请教下高手大侠们，为什么在src下，执行erl -make不能编译呢
