Compile error on @angular/cdk-experimental/scrolling using 1.0.0-alpha.23 with Angular 7

[JD Francis]

What is the current behavior?

Receiving the following error on build

ERROR in node_modules/@pebula/ngrid/lib/table/features/virtual-scroll/strategies.d.ts(5,65): error TS2307: Cannot find module '@angular/cdk-experimental/scrolling'.

Which versions of Angular, CDK, Material, NGrid, OS, TypeScript, browsers are affected?

Version: 1.0.0-alpha.23

Figured out issue. I had Angular 8 version of @angular/cdk-experimental. Installed @^7.2.0 and it compiled again
