When compiling with Scala 3 and -Xcheck-macros I get exceptions from Cask

[OndrejSpanel]

When I compile my project in Scala 3 with scalac option -Xcheck-macros, I get following exception:

Exception occurred while executing macro expansion.
scala.quoted.runtime.impl.ScopeException: Expression created in a splice was used outside of that splice.

Hint: A common reason for this to happen is when a `def` that creates a `'{...}`
      captures an outer instance of `Quotes`. If this `def` is called in a splice
      it will not track the `Quotes` provided by that particular splice.
      To fix it add a `given Quotes` to this `def`.
