Hey, I've recently started playing with a Kotlin Multiplatform. I have a bunch of native targets and I wanted to group them under nativeMain target. I did this:

val commonMain by sourceSets.getting
        val commonTest by sourceSets.getting

        val nativeMain by sourceSets.creating
        nativeMain.dependsOn(commonMain)

        targets.withType<org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget>().all {
            val mainSourceSet = compilations.getByName("main").defaultSourceSet
            val testSourceSet = compilations.getByName("test").defaultSourceSet

            mainSourceSet.dependsOn(nativeMain)
            testSourceSet.dependsOn(commonTest)
        }

I also added Okio library as a dependency in commonMain.
Now I'm trying to use Okio in a kotlin file inside nativeMain directory but it doesn't work. Looks like the dependency is not being correctly picked up.

If instead of creating this custom nativeMain source set I just use a single one like macosX64 and then put my kotlin file inside macosX64 directory then I can use the Okio and it works fine.

What am I doing wrong that the dependency doesn't work in my custom nativeMain source set?

Enable hmpp

Basically this section:
https://kotlinlang.org/docs/mpp-share-on-platforms.html#use-native-libraries-in-the-hierarchical-structure

Oh I've seen this doc but I somehow missed this section, thank you! 🙏

It worked for one lib but not for Okio, Can it be because Okio doesn't support hmpp or something? I don't know if it doesn't, I'm guessing now

Yeah, issues but they look to be resolved in the next release: https://github.com/square/okio/pull/980
