This line is inlined in your code, so it does not mean much that it is
found.

So it probably did not find the sources or the debug info I am not yet
quite sure what your setup looks like: Did you compile your Qt yourself?
Did 'make install' strip the libraries?

A usually working setup is to configure Qt with  -prefix=$PWD  without
installing it.
