How to include proto files from one project in another project

See original GitHub issue

I am not able to include protos present in Project A in a project B. The idea would be to have the protos with GrpcServices=“Server” in project A and in project B, of tests, include the same protos but, now, as GrpcServices=“Client”

ProjectA/Protos/Profile.proto

syntax = "proto3";

package profile;
option csharp_namespace = "ProjectA.Protos";
import "google/protobuf/empty.proto";

service ProfileService {
  rpc Get(google.protobuf.Empty) returns (Profile);
}

message Profile {
  string profile_id = 1;
  string description = 2;
}

ProjectA/Protos/User.proto

syntax = "proto3";

package user;
option csharp_namespace = "ProjectA.Protos";
import "google/protobuf/wrappers.proto";
import "Protos/Profile.proto";

service UserService {
  rpc Get(google.protobuf.StringValue) returns (UserDetail);
}

message UserDetail {
  string id = 1;
  string name = 2;
  repeated profile.Profile profiles = 7;
}

Project B .csproj (The test project)

<ItemGroup>
  <Protobuf Include="..\ProjectA\Protos\*.proto" GrpcServices="Client" ProtoRoot="Protos">
    <Link>Protos\*.proto</Link>
  </Protobuf>
</ItemGroup>

With these settings I always end up having this error return

error : File does not reside within any path specified using --proto_path (or -I). You must specify a --proto_path which encompasses this file. Note that the proto_path must be an exact prefix of the .proto file names -- protoc is too dumb to figure out when two paths (e.g. absolute and relative) are equivalent (it's harder than you think).
