Compatibility issue with protobuf when compiling grpc/cpp/helloworld examples

Question

I am trying to get gRpc version 1.44.0 to work on Fedora 35 (not sure OS is important).

I have build and installed gRpc following the instructions provided in the gRpc repo: https://github.com/grpc/grpc/tree/master/src/cpp

But when I try to run the helloworld example greeter client and server, I get the following error:

[libprotobuf FATAL /home/tools/Dev/libs/grpc/third_party/protobuf/src/google/protobuf/stubs/common.cc:87] This program was compiled against version 3.14.0 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.18.1).  Contact the program author for an update.  If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library.  (Version verification failed in "google/protobuf/wrappers.pb.cc".)
terminate called after throwing an instance of 'google::protobuf::FatalException'
  what():  This program was compiled against version 3.14.0 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.18.1).

(Version verification failed in "google/protobuf/wrappers.pb.cc".)
Aborted (core dumped)

Which indicates that my installed protobuf version is 3.18.1 and I compiled against 3.14.0. However, when I check my installed packages, what I get from dnf is:

Unless something inside gRpc is forcing 3.18.1 I have no idea how there should be a 3.18.1 version. Additionally I tried following this: https://stackoverflow.com/a/41975050/936269 In a virtual machine by compiling protonbuf 3.18.1 from source and the installing it (make install), but I go the same error.

How to reproduce:

1. Clone grpc
2. Follow the build from source and installation procedure
3. Follow the build of example guide
4. Run the greeter_client or greeter_server
