You don't seem to have read any of the replies.  The build directory
is not an attribute of the project layout, it is the user's choice.

And you're shooting yourself in the foot putting the configure script
anywhere but the project root.  That is where people are going to look
for it, and while I don't know that you can't make it work, I am
wondering why you feel it is important to be different from every
other Automake and Autoconf client in this regard.

But you have not explained to the list why you feel the wierd
structure is warranted.  Why don't you get things going the way that's
recommended, first, get some experience, and then starting making
dictates that break POLA after you're less likely to be shooting
yourself in the foot?
