I must admit this is surprising to me, as the line of code where LIBS=... is printed is pretty integrally coupled to the line that specifies what GNURADIO_ALL_LIBRARIES is. Maybe CMake got confused? I know this is kind of a "haveyoutriedturningitoffandonagain" answer, but have you tried completely rm'ing your build/ directory and letting CMake run anew?
