I am making .deb package for the QT 5 .2.1 desktop app for ubuntu 14.04 64 bit. I have installed QT 5.2.1 on Ubuntu 14.04 and made a demo app for the testing purpose in which I have used quazip library. During making the .deb package of the app I am getting the below issue.
dpkg-shlibdeps: error: couldn’t find library libquazip.so.1 needed by debian/demoapp/usr/bin/DemoApp1 (ELF format: ‘elf64-x86-64’; RPATH: ‘’)
dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/demoapp/usr/bin/DemoApp1 was not linked against libz.so.1 (it uses none of the library’s symbols)
dpkg-shlibdeps: error: cannot continue due to the error above
Note: libraries are not searched in other binary packages that do not have any shlibs or symbols file.
To help dpkg-shlibdeps find private libraries, you might need to use -l.
dh_shlibdeps: dpkg-shlibdeps -Tdebian/demoapp.substvars debian/demoapp/usr/bin/DemoApp1 returned exit code 2

When I copy the libquazip.so.1 at the path /usr/lib in my machine then I got the below issue .
dpkg-shlibdeps: error: no dependency information found for /usr/lib/libquazip.so.1 (used by debian/demoapp/usr/bin/DemoApp1)

I think I need to add some dependencies for quazip at the line “Depends: ${shlibs:Depends}, ${misc:Depends}” . Is there anything I have missed ? . Please have look into the issue and let me know where I did wrong.
Thanks
