Subject: [PATCH] CMakeLists.txt: allow passing a pre-existing grpc_cpp_plugin
The grpc_cpp_plugin is meant to be executed during the build process
of grpc. As such, in cross-compilation contexts, this program needs to
be built for the host machine and not the target machine. In order to
allow this, this commit adds an option gRPC_NATIVE_CPP_PLUGIN that can
be passed on the command line, with the path to an existing
grpc_cpp_plugin binary. If not passed, grpc_cpp_plugin is built as
usual.
