[mesos] 02/04: Always build gRPC with its embedded c-ares.

This is an automated email from the ASF dual-hosted git repository.

chhsiao pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/mesos.git

commit 1b21b0de2fb2958a71d01acdd0dabbc52cf14ab2
Author: Chun-Hung Hsiao <ch...@mesosphere.io>
AuthorDate: Fri Jan 4 15:40:25 2019 -0800

    Always build gRPC with its embedded c-ares.
    
    We compile gRPC with its embedded c-ares library to avoid a link error
    because Mesos is not aware of the library.
