------------------------------------
Taking care of this in the CMake refactoring
> [C++] Support double-conversion<3.1
> -----------------------------------
>
> Key: ARROW-4617
> URL: https://issues.apache.org/jira/browse/ARROW-4617
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++, Packaging, R
> Reporter: Uwe L. Korn
> Assignee: Uwe L. Korn
> Priority: Major
>
> At the moment, we require {{double-conversion>=3.1}} but distributions are
> all mostly on 2.1 or 3.0. We should support them
> Nice side-effect is that {{double-conversion}} is not good in updating their
> version number. So thus 3.0 report itself as 2.0.1 and 3.1.x as 3.0 in the
> CMake definitions. Thus we cannot rely on their version number reporting for
> detecting the version.
