I believe those should be top_srcdir and not top_builddir.  Using
configure you may build in a completely different directory from your
source and then you would notice this as a problem at that time.

  INCLUDES        = -I$(top_srcdir) -I$(top_srcdir)/lib

Use LDADD to add libraries to your link phase.

  LDADD = -lX11

Frequently this is:

  LDADD = ../lib/libmystuff.a -lX11

The local library specification is always relative, as opposed to the
$(top_srcdir) above, so that it operates out of the build area.
