@rem TODO(jtattermusch): Kokoro has pre-installed protoc.exe in C:\Program Files\ProtoC and that directory
@rem is on PATH. To avoid picking up the older version protoc.exe, we change the path to something non-existent.

@rem Just before installing gRPC, wipe out contents of all the submodules to simulate
@rem a standalone build from an archive
@rem NOTE(lidiz) We used to use "git submodule deinit", but it leaves an empty
@rem folder for deinit-ed submodules, blocking the CMake download. For users
@rem downloaded gRPC code as an archive, they won't have submodule residual
@rem folders, like the following command trying to imitate.
git submodule foreach bash -c "cd $toplevel; rm -rf $name"

@rem Install gRPC
@rem NOTE(jtattermusch): The -DProtobuf_USE_STATIC_LIBS=ON is necessary on cmake3.16+
@rem since by default "find_package(Protobuf ...)" uses the cmake's builtin
@rem FindProtobuf.cmake module, which now requires the info whether protobuf
@rem is to be linked statically.
