Relevant part of the log:

...
CMake Error at /usr/share/cmake-3.31/Modules/CMakeFindDependencyMacro.cmake:76 (find_package):
  By not providing "FindOgg.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Ogg", but
  CMake did not find one.

  Could not find a package configuration file provided by "Ogg" with any of
  the following names:

    OggConfig.cmake
    ogg-config.cmake

  Add the installation prefix of "Ogg" to CMAKE_PREFIX_PATH or set "Ogg_DIR"
  to a directory containing one of the above files.  If "Ogg" provides a
  separate development package or SDK, be sure it has been installed.

libogg with the MR changes from #1119975 fixes the lincity-ng build.
