## Current Behavior
Currently when we're using `rollup.config.ts` rollup is picking up wrong
tsconfig. Because of this not everything works as expected:
- `You are using one of Typescript's compiler options 'declaration',
'declarationMap' or 'composite'. In this case 'outDir' or
'declarationDir' must be specified to generate declaration files.` error
appears , because lib tsconfig.json doesn't have outputDir at all
- even if we add outDir to `tsconfig.base.json` we'll have another error
`[!] (plugin typescript) RollupError: [plugin typescript]
@rollup/plugin-typescript TS6377: Cannot write file
'/workspaces/abapify-docs/dist/tsconfig.tsbuildinfo' because it will
overwrite '.tsbuildinfo' file generated by referenced project
'/workspaces/abapify-docs/packages/abap-to-markdown'`
This happens becase it tries to write all tsbuildinfo files into a root
dist folder.
## Expected Behavior
Using rollup.config.ts should just work in a similar way as js|cjs|mjs
config work.
## Solution
According to docs:
> This option supports the same syntax as the
[--plugin](https://rollupjs.org/command-line-interface/#p-plugin-plugin-plugin)
option i.e., you can specify the option multiple times, you can omit the
@rollup/plugin- prefix and just write typescript and you can specify
plugin options via ={...}.
So it means we can use something like this:
```
rollup -c rollup.config.ts --configPlugin typescript={tsconfig:\'tsconfig.lib.json\'}
```
