Hi Andreas, I've updated the debian files and I decided to use quazip 0.7.1 and patch the CMakeLists.text files instead of using a development release.
Furthermore, I was not able to install the FindQuaZip.cmake file, because it is not allowed to ship a "Find module". (lintian error: https://lintian.debian.org/tags/package-contains-cmake-private-file.html). I've also added a new package called libquazip-qt5-headers to provide the headers for the Qt5 library. I hope I have uploaded the changes correctly to the git repository. For me the package works, please test the changes. Kind regards, Stefan
