I know this is an old thread, but I'm stucking with same at the moment.
What i did. Build gRPC with CMake on Mac. No failures. Then linking libs to
my project and when trying to build get the following

```
The same project with libs build on windows with CMake is working there. So
it seems to be a problem with clang on Mac. Is there any solution for this.
It seems there are many old threads on github, but none with a solution.
Thx.
