The c10d build process selectively adds files based on the `USE_C10D_FOO` flags (where `FOO` is one of `GLOO`, `NCCL` or `MPI`). Replicating this logic inside libtorch will be harder, since libtorch uses a simpler approach (i.e., it lists the files in `build_variables.bzl`). So instead we could always include all files, and "disable" each file as needed using `#ifdef`s. Note that this is not a new approach: we already do the same for all the files of the TensorPipe agent based on the flag `USE_TENSORPIPE`.
