How to fix error during ng build lib Angular?

I try to build lib in Angular:

ng build my-lib

I got this error in logs:

[error] Error: Cannot determine the module for class ɵbo in C:/Users/ponomarchuk/Desktop/Новая папка/my-workspace/node_modules/angular-cesium/angular-cesium.d.ts! Add ɵbo to the NgModule to fix it.
Cannot determine the module for class ɵbp in C:/Users/ponomarchuk/Desktop/Новая папка/my-workspace/node_modules/angular-cesium/angular-cesium.d.ts! Add ɵbp to the NgModule to fix it.

Lib has package.json:

{
  "name": "cesium-panorama-lib",
  "version": "0.0.1",
  "peerDependencies": {
    "@angular/common": "^8.2.14",
    "@angular/core": "^8.2.14"
  }
}

So, all dependencies are installed.

Root lib module is:

import { NgModule } from "@angular/core";
import { CesiumPanoramaLibComponent } from "./cesium-panorama-lib.component";
import { AngularCesiumModule } from "angular-cesium";

@NgModule({
  declarations: [CesiumPanoramaLibComponent],
  imports: [AngularCesiumModule.forRoot()],
  providers: [{ provide: "Window", useValue: window }],
  exports: [CesiumPanoramaLibComponent],
})
export class CesiumPanoramaLibModule {}
