Allow me to share this link to this programmers.SE.com question:
What is your favourite Build Automation Server software (for C++), and why?
The software tools available seem to be slightly skewed towards Java (and .NET), but what about Build Automating Servers building (continuously or nightly or on request) & testing & packaging native C++ apps? What is your experience here? How do you find the scripting? Does it scale? Is it easy to administer? Does it have a good Web interface? Etc.
