Failed to clone repository for zxing-cpp

[aeetos]

I am attempting a clean compile on ubuntu with a lot of options enabled, specifically:

./prepare.py -c ; ./prepare.py -DENABLE_PROTOBUF=ON -DENABLE_QRCODE=ON -DENABLE_VIDEO=ON -DENABLE_TRANSCODER=ON -DENABLE_CONFERENCE=ON -DENABLE_FFMPEG=ON -DENABLE_SOCI=ON -DENABLE_JPEG=ON -DENABLE_SRTP=ON -DENABLE_MPEG4=ON -DENABLE_PRESENCE=ON -DENABLE_PROTOBUF=ON -DENABLE_OPENH264=ON -DENABLE_NON_FREE_CODECS=ON -DENABLE_LIME_X3DH=ON -DENABLE_WEBRTC_AECM=ON -DENABLE_WEBRTC_AEC=ON -DENABLE_PRESENCE=ON -DENABLE_VCARD=ON -DENABLE_LIME=ON -DENABLE_G729=ON -DENABLE_V4L=ON -DENABLE_ZRTP=ON -DENABLE_OPUS=ON

This is with commit c23a39b

I get an error when it tries to clone the repo for EP_zxing

CMake Error at /root/build/flexisip_clean/WORK/flexisip/tmp/EP_zxing/EP_zxing-gitclone.cmake:40 (message):

I fixed this by changing line 29 of the EP_zxing-gitclone.cmake file from this: COMMAND "/usr/bin/git" clone --origin "origin" "git@github.com:glassechidna/zxing-cpp.git" "EP_zxing" to this COMMAND "/usr/bin/git" clone --origin "origin" "https://github.com/glassechidna/zxing-cpp.git" "EP_zxing"
