I personally use makefiles. This simplifies the management of projects, 
removes the need to specifically handle complex paths, etc. For example

# This may not be 100% correct, but you get the idea:
# make file for GNU Make
# note - \t --> tab character

# common stuff (in its own file) - common.mk

DBASE = /usr
DGCC = /usr/local
DBOOST = /usr/boost

IPATH = $(INCLUDEPATHS)
IPATH += -I "$(DBASE)/src" -I "$(DGCC)/src"
IPATH += -I "$(DBOOST)"

LPATH = $(LIBPATHS)
LPATH += -L "$(DBASE)/lib" -L "$(DGCC)/lib"
LPATH += -L "$(DBOOST)/lib"

CC = gcc -c
LNK = gcc

%.o : %.cpp
\t_at_compiling $@
\t@$(CC) -o $< $@

%.exe : %.o %.a
\t_at_building $@
\t@$(LNK) -o $< $@

# main project - makefile

include common.mk

start: hello.exe bye.exe

hello.exe: hello.o main.o
bye.exe: bye.o

---> make files rule :-)

Reece
