# Tries to find NCCL headers and libraries.
|
|
#
|
|
# Usage of this module as follows:
|
|
#
|
|
# find_package(NCCL)
|
|
#
|
|
# Variables used by this module, they can change the default behaviour and need
|
|
# to be set before calling find_package:
|
|
#
|
|
# NCCL_ROOT - When set, this path is inspected instead of standard library
|
|
# locations as the root of the NCCL installation.
|
|
# The environment variable NCCL_ROOT overrides this veriable.
|
|
#
|
|
# This module defines
|
|
# Nccl_FOUND, whether nccl has been found
|
|
# NCCL_INCLUDE_DIR, directory containing header
|
|
# NCCL_LIBRARY, directory containing nccl library
|
|
# NCCL_LIB_NAME, nccl library name
|
|
#
|
|
# This module assumes that the user has already called find_package(CUDA)
