Expected Behavior

library.sources.less theme files of a custom library dependency should be build

Current Behavior

The build result only contains the raw library.sources.less sources.

Steps to reproduce the issue

1. Clone library showcase repository

git clone https://github.com/ui5-community/ui5-library-showcase`

2. Build the app ( including its project dependencies )

cd packages/ui5-app/ && yarn run build

3. Check themes folder in dist - css files have no been generated

$ ls dist/resources/ui5/community/showcaselib/themes/sap_fiori_3
library.source.less

Context
