Problem fixed, It looks like some dependances was missing (pcap, QT5LinguistTool, libass, libvpx ...).
By manually compilling the sources, i've succed to produce the exec file.
if it could be useful for anybody in the future :
g++ *.cc -std=c++11 -O2 -g -Wall -fmessage-length=0 -D__STDC_CONSTANT_MACROS -lpthread -ldl -lm -lm -lz -lpthread -lavformat -lavcodec -lavutil -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_video -lopencv_objdetect -lpcap -lSDL -lswscale -lportaudio
thanks !
I think that I've correctly installed ffmepg, run cmake but I've errors on the linking step (Linking CXX executable drc-cap...).
All errors are "undefined reference to av_[*]", and in all ffmpeg libraries as libavcodec, utils and so on.
