Native artifact only supports linuxX64

[tclement0922]

I was using this lib in a personal project but it appears that the colorkt-native artifact (from Maven Central) only supports linuxX64.
Here is the error thrown by Gradle :

   > Could not resolve dev.kdrag0n:colorkt:1.0.5.
     Required by:
         project :
      > No matching variant of dev.kdrag0n:colorkt:1.0.5 was found. The consumer was configured to find a usage of 'kotlin-cinterop' of a library, with the library elements 'cinterop-klib', preferably optimized for non-jvm, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'native', attribute 'org.jetbrains.kotlin.native.target' with value 'mingw_x64' but:
...
          - Variant 'nativeApiElements-published' capability dev.kdrag0n:colorkt:1.0.5 declares a usage of 'kotlin-api' of a library, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'native':
              - Incompatible because this component declares a component, as well as attribute 'org.jetbrains.kotlin.native.target' with value 'linux_x64' and the consumer needed a component, as well as attribute 'org.jetbrains.kotlin.native.target' with value 'mingw_x64'
...

So right now if anyone wants to use this lib in a Multiplatform project targeting multiple native platforms (like mingwX64 or macosX64) they need to clone this repo and build the lib themselves (cross-compilation is available for all native targets expect for Apple products targets afaik).

Is there an easy way to set up all the cross-compiling targets? I can build from an Apple host.

I think the easiest way to set up all the targets is to simply do something like this:

kotlin {
    linuxX64()
    mingwX64()
    macosX64()
    ...

But if you want to use the same code for all native targets, you should add something like this in the sourceSets block:

val nativeMain by creating { dependsOn(commonMain) }
val nativeTest by creating { dependsOn(commonTest) }

val linuxX64Main by getting { dependsOn(nativeMain) }
val linuxX64Test by getting { dependsOn(nativeTest) }

val mingwX64Main by getting { dependsOn(nativeMain) }
val mingwX64Test by getting { dependsOn(nativeTest) }

val macosX64Main by getting { dependsOn(nativeMain) }
val macosX64Test by getting { dependsOn(nativeTest) }

And it looks like that cross compilation is possible from a MacOS host to almost any other targets (see there), so you'll be able to build the library for (almost) every target you want from your Apple host.
