How to create from sources deb packages for different architectures

I have to install a software on some devices with debian package, it isn't available for their architectures on apt for debian (but it is available for other distibutions as e.g. ubuntu), and they aren't powerful enough to compile it on themselves. Considering that sources are available I want to use another machine to create an easily offline installable deb package. Is there a way (or better some automatic way with something like apt-build) to do this properly without messing with all dependencies manually?
