Cannot add custom matchers for Jasmine using typescript and angular

I'm trying to add multiple new custom matchers to jasmine and use it, the goal is to create a file that register 2 matchers and all that matchers must be available for each test file with a single registration.

so i've got a file named custom-matchers.ts

/// <reference path="custom-matchers.d.ts"/>

(() => {
  beforeEach(() => {
    jasmine.addMatchers({
      toHaveText: () => {
        return {
          compare: (actual, expected) => {
            return {
              pass: actual.getText().then(pass => pass === expected)
            };
          },
        };
      },
      toBePresent: () => {
        return {
          compare: (actual, expected) => {
            return {
              pass: actual.isPresent().then(pass => pass === expected),
            };
          },
        };
      }
    });
  });
})();

A type definition file named custom-matchers.d.ts (i've tried with a different name than the references file but it's the same):

declare namespace jasmine {
  interface Matchers<T> {
    toHaveText(text: any): boolean;
    toBePresent(text: any): boolean;
  }
}

this file is registered in another file named e2e-helper, this file is imported in every test file e2e-helper.ts:

/// <reference path="custom-matchers.d.ts"/>
import './custom-matchers';

When i try to use it in a test file for exemple:

expect(object as any).toBePresent();

I got an error :

Property 'toBePresent' does not exist on type 'Matchers'
