lintian is throwing the following errors, both of them are due to unversioned .so files

lintian -i -I --show-overrides ladybug_0.15.1-1_amd64.changes
N:
E: liblbug: lacks-ldconfig-trigger usr/lib/x86_64-linux-gnu/liblbug.so
N: 
N:   The package installs shared libraries in a directory controlled by the dynamic library loader. Therefore, the package must trigger libc's "ldconfig" trigger to ensure the ldconfig cache is updated.
N:   
N:   If the package is using debhelper, dh_makeshlibs should automatically discover this and add the trigger itself. Otherwise, please add activate-noawait ldconfig to the triggers file in the control member.
N:   
N:   Note this tag may trigger for packages built with debhelper before version 9.20151004. In such case, a simple rebuild will often be sufficient to fix this issue.
N: 
N:   Please refer to ldconfig (Section 8.1.1) in the Debian Policy Manual and https://lists.debian.org/debian-devel/2015/08/msg00412.html for details.

W: liblbug: lacks-unversioned-link-to-shared-library example: usr/lib/x86_64-linux-gnu/liblbug.so [usr/lib/x86_64-linux-gnu/liblbug.so]
N: 
N:   A -dev package is supposed to install an unversioned symbolic link that references the shared library by name.
N:   
N:   There is no requirement that the names are otherwise related.
N:   
N:   The dynamic linker uses the link to load the executable into memory.
N:   
N:   In most cases, the symbolic link should be in the same folder as the library itself. A major exception are libraries installed under /lib. In those cases, the links should go into the corresponding folders under /usr.
N:   
N:   For a library installed as /lib/i386-linux-gnu/libXYZ.so.V, a good link would be /usr/lib/i386-linux-gnu/libXYZ.so.
N:   
N:   This tag is emitted for the library package and not for the -dev package. That is because Lintian looks for links after locating the library. The links can be in any of several installables, but there is only one
N:   library for each set of links pointing to it.
N: 
N:   Please refer to debian-policy 8.4 Bug#963099 for details.

Suggested fix is add the following to CMakeLists.txt

project(ladybug VERSION 0.15.1 LANGUAGES CXX)

set_target_properties(lbug PROPERTIES
    VERSION ${PROJECT_VERSION}
    SOVERSION ${PROJECT_VERSION_MAJOR}
)

@adsharma how do you want to go about it? do it in upstream or add a patch to the debian package?

[adsharma]

Both. For 0.15.1 you'll want a patch since the release is already out

[adsharma]

LGTM

We can probably enhance the man page a hit more. But can come later
