Error on execution -version `Qt_5' not found required by
On execution of eiskaltdc++ on ubuntu 15.10 ,I get the following error:

Qt version
~$ which qmake
/opt/Qt5.6.0/5.6/gcc_64/bin/qmake
~$ qmake -version
QMake version 3.0
Using Qt version 5.6.0 in /opt/Qt5.6.0/5.6/gcc_64/lib
~$ echo $PATH
/opt/Qt5.6.0/5.6/gcc_64/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
I am able to successfully compile applications with Qt creator.
Edit
running ldd gave me this.I am not sure how to interpret this

Answer
Issue happens because you have Qt installed in /usr/lib/x86_64-linux-gnu from distro which ld will use by default. To avoid such issues you can compile with -rpath or run with LD_LIBRARY_PATH=/path/to/your/Qt/libs/location to help linker find needed Qt version.
