URL: https://issues.apache.org/jira/browse/ARROW-747
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Wes McKinney
Fix For: 0.3.0
There is a potentially confusing warning from arrow/io on Linux:
{code}
-- Configuring done
CMake Warning (dev) at cmake_modules/BuildUtils.cmake:98 (add_dependencies):
Policy CMP0046 is not set: Error on non-existent dependency in
add_dependencies. Run "cmake --help-policy CMP0046" for policy details.
Use the cmake_policy command to set the policy and suppress this warning.
The dependency target "dl" of target "arrow_io_objlib" does not exist.
Call Stack (most recent call first):
src/arrow/io/CMakeLists.txt:85 (ADD_ARROW_LIB)
This warning is for project developers. Use -Wno-dev to suppress it.

I believe you may need to link to libdl on OS X
