I struggled a bit to build primeng from source, after checking the doc of angular-cli (spoiler: didn't help, they don't follow the standard) I tried all these
ng build
ng build -c production
... --aot
... --prod
...
then read the code, and some forum questions, I found the following
EDIT:

Here are the steps:
gulp clean
gulp build-assets
gulp build-exports
tsc --build tsconfig-release.json
npm pack
you can the create a release on github, and refrence it using it's URL in your package.json instead of the version number:
ex: https://github.com/<YOUR_USERNAME>/primeng/releases/download/8.0.0-rc2/primeng-8.0.0-rc.2-SNAPSHOT.tgz
