I've seen this when we were building kolab packages targeting Debian Wheezy, and I was building libkolab* for Debian unstable. There was a difference in the way these build commands are called because the Debian toolchain versions differed between wheezy and unstable. If memory serves, debhelper in sid defaults to a default setting  CMAKE_BUILD_TYPE=RelWithDebInfo, which was empty before. This causes a file LibkolabxmlTargets-RelWithDebInfo.cmake to be created instead of LibkolabxmlTargets-noconfig.cmake. So if the *.install file contains explicit references to these cmake files, it will fail on one of these versions. I put usr/lib/cmake/Libkolab/*.cmake in my libkolab-dev.install file to make it work in either version.

What I don't know what this means in the current OSB environment, though.

Cheers,

Paul
