-------------------------------------
Summary: [C++] Add infrastructure for unity builds and precompiled
headers
Key: ARROW-7725
URL: https://issues.apache.org/jira/browse/ARROW-7725
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Antoine Pitrou
Assignee: Antoine Pitrou
Unity builds and precompiled headers can be enabled "easily" in CMake 3.16:
https://cmake.org/cmake/help/v3.16/prop_tgt/UNITY_BUILD.html
https://cmake.org/cmake/help/v3.16/command/target_precompile_headers.html
They can make builds faster in some conditions, especially on CI with little
parallelism and caching.
