All reports of package-contains-cmake-private-file for the archive. The extended description of this tag is:
This package contains a file in a path reserved solely for CMake. This normally means you are shipping a Find module. Libraries should not ship Find modules at all but Config files instead.
The Config files should be installed in the unversioned path usr/(lib/<arch>|lib|share)/cmake/<name>*/
By using CMake Config files in the unversioned path, the package will continue to work as expected when a new version of CMake is uploaded.
Refer to https://wiki.debian.org/CMake and https://cmake.org/cmake/help/v3.10/manual/cmake-packages.7.html#config-file-packages for details.
This tag has not been emitted in any package tested by Lintian.
