It's actually relatively easy, but very verbose since running configure then runs the dependent lib configures as well. You just have to point the configure script to the subdirectory with another configure script.

I have a couple projects which use autotools and rely on a couple custom libraries which also use autotools. You just pass the subdirectories via AC_CONFIG_SUBDIRS: https://github.com/danomatika/joyosc/blob/master/configure.ac#L85

But in the end, I plan to simplify this layout and remove the need for this arrangement in the future.

Since we build the sources ourselves, as you have noted, it probably 
makes sense to keep them in our repo as well. I don't even know how to 
properly integrate an automake project...
