I think that this is pretty much what I do - except that I have build in
the top source directory.

yes - The development machine is not on the internet so I
have to copy the text (or export files on a USB stick).

It points to a neighbouring tree set up by autotools.
A reduced version of the auto files and build structure:
components - directory containing source for executables and libraries.
==========
components/build - directory containing build trees.
================
This is populated by autoconf and automake. I actually have several
trees for different compilers and debug and release builds under this.
components/configure.ac
