Kotlin Multiplatform

[cvb941]

Hi, I'm just raising an issue for the Kotlin Multiplatform support.

In theory it should be possible to use it, since KSP supports Multiplatform. However, I guess that we should create some sort of demo project with KMM support to be sure.

I've added information about how to run KopyKat in a Multiplatform project as part of commit b95740c. @cvb941 what do you think?

Hello, thanks for the activity on this.

I tested this on my project of interest with the following results:

Setting up copycat on kspCommonMainMetadata does not seem to generate any code.
Using kspAndroid instead results in a lot of build errors (excerpt below)

...
e: /Users/cvb941/src/shared/build/generated/ksp/android/androidLocalDebug/kotlin/so/shared/presentation/group/so.shared.presentation.group.GroupDetail$State$Mutable.kt: (68, 83): Unresolved reference. None of the following candidates is applicable because of receiver type mismatch:

Just wanted to mention that this issue still exists, also for target kspJvm. KopyKat is not usable with Kotlin Multiplatform.
