Libcfa make can now stop cfa-cpp when starting so a gdb session will be attached to it.
Use make ... gdbwaittarget=FILENAME where the filename is the same as the one printed when building with the silent rules.
cfa-cpp will print the gdb command to attach to it.
You may need to change linux permissions for gdb attach, just Google it.
