Description

See https://github.com/apache/arrow/pull/8468#issuecomment-807807284. We either need to fix the build (maybe there's something not getting passed through to build_re2 correctly in cmake) or figure out the conditions under which the C++ build should turn off re2.

See also ARROW-11736 to make regex compute functions optional in R tests.
