# gRPC & protobuf - build using CMake
# Use the protobuf version from gRPC for everything to avoid conflicting
# versions to be linked in. Disable OpenSSL embedding: when it's on, the build
# process of gRPC puts the OpenSSL static object files into the gRPC archive
# which causes link errors later when the agent is linked with the static
# OpenSSL library itself.
# Limit the number of threads used by make, as unlimited threads causes
# memory exhausted error on the Kokoro VM.
