AndroidStudio用Build Output查看CMak

CMake可以通过message命令进行打印内容，但是在AndroidStudio中使用不同版本的CMake会导致message输出形式不同。

我借鉴这位博主的经验后借鉴链接将项目root目录下的build.gradle中的CMake版本改成了version "3.6.0"后就可以看到编译输出了。

具体gradle文件如下:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.0"

    defaultConfig {
        applicationId "com.epimenides.cmakedemo"
        minSdkVersion 25
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

        externalNativeBuild {
            cmake {
                cppFlags ""
            }
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

    externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
            version "3.6.0"
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

最后得到的Sync输出提示为:

CONFIGURE SUCCESSFUL in 3s

可以得到结论: 编译文件的最终会被写入到

$your-proj/$your-module/.cxx/cmake/debug/x86
