I support Evan's approach, too. With automake generated Makefiles it was
not a real option since the cross-directory make target dependencies were
not complete, and with the recursive nature of the generated Makefile structure
it was not really manageable easily. I think after switching to CMake and
removing automake build system we could remove all generated files, too.
