Description
It seems that when compiling with -DARROW_WITH_BACKTRACE=OFF we don't add anymore the -DARROW_EXPORTING definition.
That definition is what makes ARROW_EXPORT switch between dllimport and dllexport.
The result is thus that the build fails with errors like

The issue seems to be related to this code block in CMakeLists.txt
if(ARROW_WITH_BACKTRACE) find_package(Backtrace) foreach(LIB_TARGET ${ARROW_LIBRARIES}) target_compile_definitions(${LIB_TARGET} PRIVATE ARROW_EXPORTING) if(Backtrace_FOUND AND ARROW_WITH_BACKTRACE) target_compile_definitions(${LIB_TARGET} PRIVATE ARROW_WITH_BACKTRACE) endif() endforeach() endif()
