             Summary: find_package_helper makes using packages REQUIRED
                 Key: MESOS-9005
                 URL: https://issues.apache.org/jira/browse/MESOS-9005
             Project: Mesos
          Issue Type: Improvement
          Components: cmake
         Environment: We currently implement a cmake function {{find_package_helper}} which, in addition to finding package artifacts, also by hand implements much of the functionality of {{find_package_handle_standard_args}}.

One aspect not replicated is the handling of the {{REQUIRED}} flag to {{find_package}}. Instead {{find_package_helper}} always generates a hard error if an artifact cannot be found.

It might be simpler to separate the discovery logic from the error handling logic, and delegate as much as possible to {{find_package_handle_standard_args}} so that we not only simplify our custom code, but also get the expected {{find_package}} semantics.
