                 Key: ARROW-17763
                 URL: https://issues.apache.org/jira/browse/ARROW-17763
             Project: Apache Arrow

          Components: C++
    Affects Versions: 9.0.0
            Reporter: Stefan Novak


Hello!

I've been looking into incorporating Arrow into a Bazel build build project and have been having some challenges getting it to work.

I've been using Bazel's [rules_foreign_cc|https://bazelbuild.github.io/rules_foreign_cc/main/index.html] to call CMake, however the build process is erroring out as [described by another community member|[https://github.com/bazelbuild/rules_foreign_cc/issues/879]].

One thing that I've learned: Bazel's C++ integration will [specify|[https://github.com/bazelbuild/bazel/blob/5.3.0/tools/cpp/unix_cc_configure.bzl#L622-L624|https://github.com/bazelbuild/bazel/blob/5.3.0/tools/cpp/unix_cc_configure.bzl#L622-L624]).]] `__DATE__`, `__TIME__`, and `__TIMESTAMP__` flags to ensure reproducible builds.

These values are expected to be quoted strings. However, when Arrow's toolchain [translates|[https://github.com/apache/arrow/blob/apache-arrow-9.0.0/cpp/cmake_modules/ThirdpartyToolchain.cmake#L4874]] `CMAKE_CXX_FLAGS` to `ARROW_CXX_COMPILER_FLAGS`, CMake is [calling|https://github.com/apache/arrow/blob/apache-arrow-9.0.0/cpp/cmake_modules/ThirdpartyToolchain.cmake#L4874] `configure_file(...)` with the `ESCAPE_QUOTES` option which is mucking up the parsing.

Does anyone happen to have any recommendations for a workaround or a fix?

Thank you! I appreciate everyone's efforts in continuing to develop Arrow.

Cheers,
Stefan
