工作代码片段-makefile模板

项目领导要求比较高，全部是手写makefile，没有借助autotools或者cmake之类，不过却形成了一个可以复用的定义模板：

ifdef release
DIR = .
LIB_DIR    = ${DIR}/../../../lib/fep
DEPS       = -lplatform -lappconf -lconfig -ltinyxml -lkhreadline
CFLAGS     = -O2 -fPIC -rdynamic -Wall
LDFLAGS    = -fPIC -m64 -lreadline -lncurses -Wall
else
DIR        = $(shell pwd)
LIB_DIR    = 
DEPS       = ${LIB_DIR}/libplatform.so
CFLAGS     = -O2 -fPIC -rdynamic -pg -Wall
LDFLAGS    = -fPIC -m64 -lreadline -lncurses -pg -Wall
endif
