Subject: emotion: use eina_prefix to determine player location.
X-Git-Tag: 2.0_alpha~128
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=974697054af53b51372049daf8863a3b24dc66ac;p=framework%2Fuifw%2Femotion.git

emotion: use eina_prefix to determine player location.

Move players from $bindir to $libdir/emotion/utils and find them with
eina_prefix. I was willing to play with this prefix thing, quite nice
;-)
