What is the lib file for Acero/Arrow compute?

Hi,

I just noticed there is no specific lib file for Acero/Arrow compute when I
have BUILD_COMPUTE=ON - is it included in the libarrow.so?

Thanks!
Li

Yeah, it's just part of libarrow.so. There's a long-standing issue to try to split out (most of) the compute kernels into a separate library to slim down the main one, but the issue is that we probably want to keep casts (and perhaps a few other kernels) in the main library. AIUI, we may also want to split out acero/the "engine" as well (or at least give it its own CMake flag eventually).
