Is there a way to specify dependencies between convenience libraries, and also set the relevant include paths?

Convenience libraries do not have normal dependencies because they are not used as libraries (they are just bundled object files). However, you can use libNAME_la_LIBADD to add them as an linkage dependency for another library and Automake will take that into consideration when ordering the build within the same directory and also apply the objects from the convenience library while linking. If the convenience library is built in some other directory, you have to ensure that SUBDIRS in the upper is listed in the correct order so that the convenience library is built before it is used.

For example (if convenience library is in some other directory):

libNAME_la_LIBADD = $(top_builddir)/convenience/

or (if convenience library is in same directory):


In my opinion, convenience libraries are evil (they dramatically slow down the build) and it is better to use a non-recursive build, using Makefile variables to list the required object files in the link rather than using a convenience library.
