| # The goal of this package is to enable *basic* builds of NCCL. Any | ||
| # configuration that would require modification to the provided | ||
| # makefile is considered out-of-scope and users needing such | ||
| # configuration should consider a standalone build rather than | ||
| # superbuilding NCCL. | ||
| # | ||
| # Note that the default NCCL makefile is rather rigid. It looks like | ||
| # one _can_ inject flags, but they have a high likelihood of being | ||
| # trampled by the makefile. E.g., the makefiles specifies optimization | ||
| # flags *after* the user injection point, so trying to modify the | ||
| # optimization level manually would be moot. | ||
