How config cmake in kotlin multiplatform project?

When config as the following DSL in build.gradle

android {

    defaultConfig {
        externalNativeBuild {
            cmake {
                abiFilters  "arm64-v8a","armeabi-v7a"
            }
        }
    }

    externalNativeBuild {
        cmake {
            path 'CMakeLists.txt'
        }
    }
}

kotlin {
    macosX64(){
    }
    linuxX64() {
    }
}

I got an CONFIGURE FAILED error:
ABIs [armeabi] are not supported for platform. Supported ABIs are [arm64-v8a, armeabi-v7a, x86, x86_64].

My project structure is shown in the attached image, How can I solve it?

Hello, @Jeff Beyond! Can you explain a bit - what exactly you’re trying to do here? Are you trying to use CMake as to build Kotlin/Native Android target? I’m not sure this would work correctly.

[Kris Wong]

it's my understanding abiFilters goes in defaultConfig.ndk

[Kris Wong]

oh I see the difference:

/**
     * Specifies the Application Binary Interfaces (ABI) that Gradle should build outputs for. The
     * ABIs that Gradle packages into your APK are determined by {@link
     * com.android.build.gradle.internal.dsl.NdkOptions#abiFilter
     * android.defaultConfig.ndk.abiFilter}

[Kris Wong]

I would try that as a first step

@Artyom Degtyarev [JB] My project used to be an Android project, which contained a part of jni logic implemented in C++ and build with cmake. I am now transforming it into a kotlin multiplatform project, but I want to keep the jni logic written in C ++ and cmake build to support android target, is this possible?

[Jeff Beyond]

@Kris Wong so what should I do?

[Kris Wong]

i think my recommendation was pretty clear. is there a particular part that's confusing?

[Jeff Beyond]

@Kris Wong I tried it, but it did not work.

[Kris Wong]

that's unfortunate
