CMake Error at cmake/modules/RootMacros.cmake:1548 (target_link_libraries):
  Target "rootcling_stage1" links to:

    zstd::libzstd_shared

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.
