Typical <package>Config.cmake files for find_package() rely only on the files generated by install(EXPORT). They might be wrong, for whatever reasons, like people manually deleted files, projects were packaged wrong by distributions, whatever. To protect against this, add checks that the file locations we are importing actually exist on disk. Alex
