[Interest] Per-language lupdate options not possible with qt_add_lupdate CMake helper?

[Alexandru Croitor]

Hi,

Unless i'm misreading the code, i don't think it's currently possible to pass per-file / per-lang
separate options for a single target with qt_add_lupdate.

You could try to work around it by having separate targets per language, but that's clearly sub-optimal.

You should be fine with using qt_create_translation as long as it meets your needs, we likely won't remove
any deprecated api until there is a good enough replacement.

Having said that, I suggest you file a suggestion on the bug tracker, so we can keep track of the use case.
