I have a project where several different build must coexist together (libtool, CMake, ...) I would like to rename my GNUmakefile to GNUmakefile.gnustep, because the main build is using libtool and so I want avoid conflicts when typing make.
If I rename all the GNUmakefile files to GNUmakfile.gnutep, then : make -f GNUmakfile.gnustep does not work because it's still looking for GNUmakfile (and not GNUmakfile.gnustep) in sub dirs.
I think I have to set a variable in the top level GNUmakfile.gnustep, but I cannot find it.
