`package-contains-cmake-private-file`

The package ships a file in a location reserved for CMake. It usually means you shipped a Find module.

Libraries should not ship Find modules Config files. Config files should be installed in the unversioned path usr/(lib/<arch>|lib|share)/cmake/<name>*/

When CMake Config files are installed in an unversioned path, your package will continue to work when a new version of CMake is uploaded.
