Comment 1 for bug 1267835

This change intelepathy-qt5-0.9.3/cmake/modules/TpQtMacros.cmake will make the cmake and compilation steps succeed

- qt5_create_moc_command(${abs_infile} ${outfile} "${moc_flags}" "-i")
+ qt5_create_moc_command(${abs_infile} ${outfile} "${moc_flags}" "-i" "")

then it fails at some later dpkg symbol checking state but i that's something that is much more in your real of knowledge than not mine.
