[GitHub] [arrow] Eleobert opened a new issue, #14478: r2 undefined reference

Eleobert opened a new issue, #14478:
URL: https://github.com/apache/arrow/issues/14478

   I get undefined references to r2 when I try to compile my project. Here is the cmake file:
   
   ```
   cmake_minimum_required(VERSION 3.14 FATAL_ERROR)
   
   project(proj)
   
   find_package(Arrow REQUIRED)
   
   add_executable(proj src/main.cpp)
   
   target_compile_features(proj PRIVATE cxx_std_20)
   target_link_libraries(proj arrow::arrow)
   ```
   
   And conanfile:
   
   ```
   [requires]
   arrow/8.0.1
   
   [options]
   arrow:parquet=True
   arrow:filesystem_layer=True
   arrow:dataset_modules=True
   
   [generators]
   CMakeToolchain
   CMakeDeps
   ```
   
   Adding `arrow:with_re2=True` does not work, adding re2 as a separate dependency also does not work, neither adding a separate `find_package` and `target_link_library` with re2.
   
   I am trying to compile the example from https://arrow.apache.org/docs/cpp/dataset.html

   The solution is to link re2 as `re2` instead of `re2::re2`.

   The solution is to link re2 with `target_link_library` as `re2` instead of `re2::re2`.
