一个很不错的关于编译系统的评述：

name	decision	pros	cons	link
ant	not evaluated	- good log output - fast startup speed	cc task is not flexible.
rake	bad	same as rant	- no dependency check - same as rant
rant	bad	fast incremental build speed	- can't generate vc projects - no build-in support of out-of-source build
cmake	not good	- chosed by KDE as build tool. Has potencial to be better.	- not build tool, but makefile generator. - limited by native makefiles. - hard to do automation	http://www.cmake.org/
omake	not evaluated
scons	current the best choice	- I've used it for a long time. - flexible	slow incremental build time
a-a-p	not evaluated			http://www.a-a-p.org/
bjam	bad		- slow build speed - strange language - mailing list is full of shit
jam	bad		dead project already
