Seems ok to me.

BTW, whenever you add @substed@ values to *_LIBADD, automake cannot know
whether these substed values will contain references to other
uninstalled libraries or objects, for which it would be nice to add make
dependencies to, so the library is rebuilt when they are updated.  In
that case, what you can do is fill out the corresponding *_DEPENDENCIES
variable yourself, in that case with all library dependencies of course.

You can override DIST_SUBDIRS to avoid this.  In your particular case,
you should set it in evas/src/lib/Makefile.am, to the empty value.

Hope that helps.

Cheers,
