cmake: fix detecting libidn2

Without this patch, libidn2 detection doesn't even seem to be
attempted. With this patch, cmake can be configured to pick it
up and enable it. Necessary configuration remains manual and
differs from most other dependencies.

If you are aware of a better fix, we're glad hearing about it
in a new Issue.

Closes #8917
