Building library from source

[Jaromír Mikeš <mira.mikes@seznam.cz>]

Hello,

I build new library from source building process run with one warning message. 
dpkg-gencontrol: warning: unknown substitution variable ${shlibs:Depends}
Despite of this packages are build.
Lintian ...clean output.
Problem is that library installing just .docs files no .so files.
I've checked everything many times.

What I forgot to check?

regards
