Too large grpc.lib file on Windows

[magnesj]

What version of gRPC and what language are you using?

1.68 c++

What operating system (Linux, Windows,...) and version?

Windows 11
MSVC 17.12.4

What runtime / compiler are you using (e.g. python version or version of gcc)

MSVC 17.12.4

What did you do?

Created a build of grpc using vcpkg

What did you expect to see?

A generated file that can fit into build cache on GitHub Action.

What did you see instead?

A very large lib-file that was rejected by the build cache on GitHub Action.

Anything else we should know about your project / environment?

Issue reported in vcpkg microsoft/vcpkg#43454

File size on disk for some libraries in the same build:

I'm unfamiliar with the specifics of how vcpkg builds grpc.lib (and I should mention that vcpkg isn't something we maintain). Could you investigate the contents of those library files? I'm particularly interested in whether they might include debugging symbols.

Thanks for your reply.

You are right, the output from dumpbin indicates a large section with debug info. I have instructed vcpkg to build only release, but this does clearly not work as expected. Do you have any recommendations for a static release build on Windows?

We have use grpc for some years now and the binary size of the lib file has increased significantly lately.

Here is the vcpkg build configuration
