1.externalNativeBuild 区别

1.1harmonyos

ohos {
    compileSdkVersion 5
    defaultConfig {
        compatibleSdkVersion 5
    }
    buildTypes {
        release {
            proguardOpt {
                proguardEnabled false
                rulesFiles 'proguard-rules.pro'
            }
        }
    }
    externalNativeBuild {
        path "src/main/cpp/CMakeLists.txt"
        // arguments "-v"
        arguments "-DTEST_LIBRARY_SRC=${rootProject.projectDir}/"
        abiFilters "arm64-v8a"
        cppFlags "-std=c++17"
    }
}

1.2Android

android {
    compileSdk 32

    defaultConfig {
        minSdk 21
        targetSdk 32

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles "consumer-rules.pro"
        externalNativeBuild {
            cmake {
                cppFlags '-std=c++17 -D__STDC_LIMIT_MACROS'
                arguments "-DHASH_LIBRARY_SRC=${rootProject.projectDir}/third_party/hash-library"
            }
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
            version "3.18.1"
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
    namespace 'com.mgg.checkenv'
}

1.3小结

externalNativeBuild 使用的位置，包含参数不一样。
