ExternalNativeBuildFlags

@Incubating
interface ExternalNativeBuildFlags

DSL object for per-variant CMake and ndk-build configurations, such as toolchain arguments and compiler flags.

android {
    // Similar to other properties in the defaultConfig block, you can override
    // these properties for each product flavor you configure.
    defaultConfig {
        // This block is different from the one you use to link Gradle
        // to your CMake or ndk-build script.
        externalNativeBuild {
            // For ndk-build, instead use the ndkBuild block.
            cmake {
                // Passes optional arguments to CMake.
                arguments "-DANDROID_ARM_NEON=TRUE", "-DANDROID_TOOLCHAIN=clang"

                // Sets a flag to enable format macro constants for the C compiler.
                cFlags "-D__STDC_FORMAT_MACROS"

                // Sets optional flags for the C++ compiler.
                cppFlags "-fexceptions", "-frtti"

                // Specifies the library and executable targets from your CMake project
                // that Gradle should build.
                targets "libexample-one", "my-executible-demo"
            }
        }
    }
}

To enable external native builds and set the path to your CMake or ndk-build script, use android.externalNativeBuild.
