Conditional data-files

[augustss]

What is your question?
I need to install different data-files depending on a condition (in my case which compiler it is).
I tried using an if, but that doesn't seem to work.

Is there no way to do this? Or am I just being stupid?

System information
cabal-install version 3.12.1.0
compiled using version 3.12.1.0 of the Cabal library

I haven't tested this but from the docs it looks like conditionals are not available for data-files:

Conditional blocks may appear anywhere inside a component or common section.
