function buildSignalConfig(options: {
  wellknown: {
     Array: string | symbol;
  };
}): {
  createMemo: <F>(object: object, key: string | symbol, fn: () => F) => () => F;
  waitFor: <K>(promise: Promise<K>) => Promise<K>;
  willSyncFlushWatchers: () => boolean;

Defined in: [index.ts:32](https://github.com/warp-drive-data/warp-drive/blob/8f937cd149b31525e1948de56087f9f54e7c1f0e/packages/tracking/src/index.ts#L32)

Creates a signal configuration object for WarpDrive that integrates with Ember's
reactivity system. This will be automatically imported and registered by
`@ember-data/store` if the deprecation has not been resolved.

This function should not be called directly in your application code
and this package is deprecated entirely. Use [@warp-drive/ember](../../../@warp-drive/ember/index.md)
instead.
