Angular compilation Fails: "../Address.ts is missing from the TypeScript compilation"

[razorsyntax]

Rather than use the angular scaffolding (it appears outdated) I'm integrating it into an existing angular project. When the angular app compiles I receive the following warnings:

Module build failed (from ./node_modules/@ngtools/webpack/src/index.js):
Error: /Users/{user}/Desktop/Test/bch-test/node_modules/bitbox-sdk/lib/TransactionBuilder.ts is missing from the TypeScript compilation. Please make sure it is in your tsconfig via the 'files' or 'include' property.
The missing file seems to be part of a third party library. TS files in published libraries are often a sign of a badly packaged library. Please open an issue in the library repository to alert its author and ask them to package the library using the Angular Package Format (https://goo.gl/jB3GVv).
