Since grpc 1.51.1 upload in Debian sid, clangd + libgrpc (-DCLANGD_ENABLE_REMOTE=ON) fails to link with:

This issue was marked as completed by 9f3081d, but that commit has since been reverted in 275bca6. Should the issue be reopened?

[cachemeifyoucan]

I reopen it because I am fixing it. It would be good if people affected by this bug try out the new fix. Note you might need to update CMake configuration to find the cmake package for grpc.
