+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.
