# - Find RDMA
# Find the New TIRPC RPC library
#
# This module accepts the following optional variables:
# RDMA_PATH_HINT = A hint on RDMA install path.
#

# RDMA_FOUND = Was RDMA found or not?
# RDMA_LIBRARY = The list of libraries to link to when using RDMA
# RDMA_INCLUDE_DIR = The path to RDMA include directory(s)
#
# One can set RDMA_PATH_HINT before using find_package(RDMA) and the
# module with use the PATH as a hint to find RDMA.
# Alternatively, one can set LIBIBVERBS_PREFIX and LIBRDMACM_PREFIX to the individual
# hints for those libraries.
