there also migh be some roadblock down the road: https://lists.cinelerra-cv.org/pipermail/cinelerra/2017q3/006867.html
but for now you either can try to run configure with CFLAGS=-I/path/to/a52dec or add your system's include path to configure.ac (like it done at beginning of this file for freetype) unfortunately liba52 does not provide .pc (pkg-config) file, so.. may be we can augment all our includes with ifdef so it will be #include "a52.h" if we have both thirdparty and a52dec building, and #include "a52dec/a52.h" if we try to use system copy... also https://www.cinelerra-gg.org/bugtracker/view.php?id=359&nbn=2 (closed, but see comment.. i wonder if compile failure was due to missing include or something else..)
