[Freeswitch-users] Are source debs/tar.gz available for libks signalwire-client-c?

When building 1.8.4 RPMs on CentOS 7 it fails when looking for libks, signalwire-client-c. I was looking for the source to build RPMs but couldn't find the source debs either. Are these binary only packages? root@6f121bb43cbd:/# apt-cache showsrc libks W: Unable to locate package libks N: No packages found root@6f121bb43cbd:/# apt-cache showsrc signalwire-client-c W: Unable to locate package signalwire-client-c N: No packages found -- Richard Chan
