This is the problem, if you added your correct lib path in 
/etc/ld.so.conf.d/qgis.conf (filename is not important, only the extension is 
important) then run sudo ldconfig your system should find them.

First, run sudo updatedb then wait for a while. Finaly check the location 
locate libqgis_gui.so.2.3.0

It gives you at least two location: your build src and your lib install path. 
Take the second one and put it into /etc/ ld.so.conf.d/qgis.conf, run again 
sudo ldconfig

check again with your ldd command.
