[Cin] Build from git

[Andrew Randrianasulu]

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...

(closed, but see comment.. i wonder if compile failure was due to missing
include or something else..)
