gRPC: CMake install does not copy .pdb files

Question

I'm currently using gRPC 1.62.1 on my Windows 10 machine with VS 2019.

I followed the instructions on https://github.com/grpc/grpc/blob/master/BUILDING.md but after the debug build was successful the CMake install does not copy the .pdb files. (The .pdb files will be created during the build)

Following commands have been used:

mkdir _build
mkdir _install
mkdir _install\debug
mkdir _install\release
cmake -B"./_build" -H"." -DCMAKE_INSTALL_PREFIX=C:\Users\flag\Downloads\grpc-1.62.1\grpc\_install\debug -DABSL_PROPAGATE_CXX_STD=ON -DgRPC_INSTALL=ON
cmake --build ./_build --target install --config=Debug

Also tried this but same effect.

cmake -B"./_build" -H"." -DABSL_PROPAGATE_CXX_STD=ON
cmake --build ./_build --target install --config=Debug

Maybe someone could help me with this issue.
