pytorch/setup.py

Reorganize third-party libraries into top-level third_party directory (#6025)
- gloo, pybind11, nanopb and nccl now live in third_party.
- ATen builds in aten/build rather than torch/lib/build/aten
- A bit of faffing about in the scripts was necessary, because they used to assume that everything lived in the same directory. Now you are expected to cd into the correct directory before calling one of the build functions. The actual builder script lives in tools
- Lint now just unconditionally ignores third_party, rather than enumerating folders explicitly

# Welcome to the PyTorch setup.py.
#
# Environment variables you are probably interestd in:
#
# DEBUG
# build with -O0 and -g (debug symbols)
#
# MAX_JOBS
# maximum number of compile jobs we should use to compile your code
#
# NO_CUDA
# disables CUDA build
#
# CFLAGS
# flags to apply to both C and C++ files to be compiled (a quirk of setup.py
# which we have faithfully adhered to in our build system is that CFLAGS
# also applies to C++ files, in contrast to the default behavior of autogoo
# and cmake build systems.)
#
# CC
# the C/C++ compiler to use (NB: the CXX flag has no effect for distutils
# compiles, because distutils always uses CC to compile, even for C++
# files.
#
# Environment variables for feature toggles:
#
# NO_CUDNN
# disables the cuDNN build
#
# NO_NNPACK
# disables NNPACK build
#
# NO_DISTRIBUTED
# disables THD (distributed) build
#
# NO_SYSTEM_NCCL
# disables use of system-wide nccl (we will use our submoduled
# copy in third_party/nccl)
#
# WITH_GLOO_IBVERBS
# toggle features related to distributed support
#
# PYTORCH_BINARY_BUILD
# toggle static linking against libstdc++, used when we're building
# binaries for distribution
#
# PYTORCH_BUILD_VERSION
# PYTORCH_BUILD_NUMBER
# specify the version of PyTorch, rather than the hard-coded version
# in this file; used when we're building binaries for distribution
#
# Environment variables we respect (these environment variables are
# conventional and are often understood/set by other software.)
#
# CUDA_HOME (Linux/OS X)
# CUDA_PATH (Windows)
# specify where CUDA is installed; usually /usr/local/cuda or
# /usr/local/cuda-x.y
#
# CUDNN_LIB_DIR
# CUDNN_INCLUDE_DIR
# CUDNN_LIBRARY
# specify where cuDNN is installed
#
# NCCL_ROOT_DIR
# NCCL_LIB_DIR
# NCCL_INCLUDE_DIR
# specify where nccl is installed
#
# NVTOOLSEXT_PATH (Windows only)
# specify where nvtoolsext is installed
#
# LIBRARY_PATH
# LD_LIBRARY_PATH
# we will search for libraries in these paths
