cannot import proto file

Question

I have spent hours trying to read blogs on how to use simple proto file in Golang. I generated the .pb.go files. All internet examples are littered with doing import from some random "github... urls for proto import. I am not able to find any example on how to import a simple proto file that exists in same dir as my .go file or diff directory. How do I use proto files from local file systems.

go build hello.go
hello.go:5:2: cannot find package "customer" in any of:
    /usr/local/go/src/customer (from $GOROOT)
    /Users/myhomedir/go/src/customer (from $GOPATH)

Contentes of hello.goin $SOME_DIR/customer

package main

import  (
    "fmt"
    pb "customer"
)

func main() {
    fmt.Println("hello test message\n")
}

Contents of customer.proto

syntax = "proto3";
package customer;


// The Customer service definition.
service Customer {
  // Get all Customers with filter - A server-to-client streaming RPC.
  rpc GetCustomers(CustomerFilter) returns (stream CustomerRequest) {}
  // Create a new Customer - A simple RPC
  rpc CreateCustomer (CustomerRequest) returns (CustomerResponse) {}
}

// Request message for creating a new customer
message CustomerRequest {
  int32 id = 1;  // Unique ID number for a Customer.
  string name = 2;
  string email = 3;
  string phone= 4;

  message Address {
    string street = 1;
    string city = 2;
    string state = 3;
    string zip = 4;
    bool isShippingAddress = 5;
  }

  repeated Address addresses = 5;
}

message CustomerResponse {
  int32 id = 1;
  bool success = 2;
}
message CustomerFilter {
  string keyword = 1;
}

Just put the Customer code in a directory and import it like you would a package

package main
import "$SOME_DIR/customer"
