--------------------------------------

             Summary: [C++] find_package(Arrow) is broken on Ubuntu 18
                 Key: ARROW-10495
                 URL: https://issues.apache.org/jira/browse/ARROW-10495
             Project: Apache Arrow
          Issue Type: Bug
          Components: Packaging
    Affects Versions: 2.0.0
         Environment: Ubuntu 18
            Reporter: Oksana Shadura


On Ubuntu 18, after updating Arrow version to 2.0.0, ROOT  ([https://github.com/root-project/root)] builds are broken:
CMake Warning at cmake/modules/SearchInstalledSoftware.cmake:16 (_find_package):
  By not providing "FindRE2.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "RE2", but
  CMake did not find one.

  Could not find a package configuration file provided by "RE2" with any of
  the following names:

    RE2Config.cmake
    re2-config.cmake

  Add the installation prefix of "RE2" to CMAKE_PREFIX_PATH or set "RE2_DIR"
  to a directory containing one of the above files.  If "RE2" provides a
  separate development package or SDK, be sure it has been installed.
Call Stack (most recent call first):
  /usr/share/cmake-3.10/Modules/CMakeFindDependencyMacro.cmake:48 (find_package)
  /usr/lib/x86_64-linux-gnu/cmake/arrow/ArrowConfig.cmake:95 (find_dependency)
  cmake/modules/SearchInstalledSoftware.cmake:16 (_find_package)
Looks like a problem is that for a Debian/Ubuntu packaging is missing _FindRE2.cmake_ in a list [https://github.com/apache/arrow/blob/master/dev/tasks/linux-packages/apache-arrow/debian/libarrow-dev.install]

CMake files I got after installation:

Manually adding _FindRE2.cmake_ in _/usr/lib/x86_64-linux-gnu/cmake/arrow_ is fixing CMake configuration issue.
