gRPC 1.7.2 + OpenSSL 1.1.0

[minyan...@gmail.com]

It appears that the latest gRPC release (1.7.2) does not compile with OpenSSL 1.1.0g.  Both packages are the latest releases as of now (Nov 15, 2017).  A quick googling returned a couple github issues such as this one:

https://github.com/grpc/grpc/issues/8801

gRPC build using cmake toolchain fails at grpc_print_google_default_creds_token as follows:

I'm wondering if this is a known issue and any patch is coming along the way (no issue with BoringSSL in third_party).  Any comment/information about gRPC + OpenSSL would be appreciated.

Thanks!
