Use VPATH to make debug and release builds use the same set of source files. The debug and release build can have their own directory, which means they'll have their object files separated.

Alternatively, use a build tool that supports out-of-source builds natively, like automake or (ugh) cmake.

If you enable the automake option subdir-objects (as in AM_INIT_AUTOMAKE([foreign subdir-objects])), you can write a non-recursive Makefile.am.
