If it helps, years ago I made changes to automake to produce Makefile from Makefile.am, rather than Makefile.in which has to be processed by the configure script. This avoids the impossible situation of Makefile calling configure if configure produces Makefile itself. Perhaps some of the ideas/code from this could be used. https://lists.gnu.org/archive/html/automake/2013-04/msg00034.html https://github.com/GavinSmith0123/automake-amplain/tree/amplain
