5b9f7f7b - [cmake] Add USE_SYSTEM_{GLOO,FP16,PTHREADPOOL,PSIMD,FXDIV,BENCHMARK} options (#14699) (#37277)

[cmake] Add USE_SYSTEM_{GLOO,FP16,PTHREADPOOL,PSIMD,FXDIV,BENCHMARK} options (#14699) (#37277) Summary: These options are disabled by default, and are supposed to be used by linux distro developers. With the existing shortcut option USE_SYSTEM_LIBS toggled, these new options will be enabled as well. Additionally, when USE_SYSTEM_LIBS is toggled, setup.py should no longer check the existence of git submodules. ezyang Pull Request resolved: https://github.com/pytorch/pytorch/pull/37277 Differential Revision: D21256999 Pulled By: ezyang fbshipit-source-id: 84f97d008db5a5e41a289cb7bce94906de3c52cf
