エラーメッセージ

CMake Error at ~/.local/lib/cmake/lib/cmake/AwsFindPackage.cmake:19 (find_package):
  By not providing "Findaws-c-io.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "aws-c-io",
  but CMake did not find one.

  Could not find a package configuration file provided by "aws-c-io" with any
  of the following names:

    aws-c-ioConfig.cmake
    aws-c-io-config.cmake

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

エラーメッセージで検索してもひっかからないし、
MAC上で半年や１年ほど前に特に難しい事せずに公式通りでビルドしてる記事がみつかるので
バージョンが新しすぎるせい？な気がしてるんですが

MAC上で aws-sdk-c++ がビルドできてる方いたら
cmake, aws-c-event-stream, aws-sdk-c++ のバージョンを教えていただけないでしょうか
