I can't compile telegram source code with NDK

Question

I installed NDK and set the NDK path in "Project Structure" :

And then I added below codes to build.gradle:

task buildNative(type: Exec, description: 'Compile JNI source via NDK') 
{
    def ndkDir = android.ndkDirectory
    commandLine "$ndkDir/ndk-build.cmd",
                '-C', file('jni').absolutePath, // Change src/main/jni the relative path to your jni source
                '-j', Runtime.runtime.availableProcessors(),
                'all',
                'NDK_DEBUG=1'
}

task cleanNative(type: Exec, description: 'Clean JNI object files') {
    def ndkDir = android.ndkDirectory
    commandLine "$ndkDir/ndk-build.cmd",
                '-C', file('jni').absolutePath, // Change src/main/jni the relative path to your jni source
                'clean'
}

clean.dependsOn 'cleanNative'

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn buildNative
}

And add this code to "defauilConfig" in build.gradle :

ndk {
       moduleName "TMessagesProj"
}

When I try to build an APK , I get this error :

Error:Execution failed for task ':TMessagesProj:buildNative'. Process 'command 'C:\Users\Mehran\AppData\Local\Android\ndk\android-ndk-r12/ndk-build.cmd'' finished with non-zero exit value 2

This is the Messages Console :

make (e=2): The system cannot find the file specified. make: *** [D:/Mehran/AndroidStudioProjects/TelegramTest/TMessagesProj/obj/local/armeabi/objs-debug/tmessages.22/./opus/src/opus_encoder.o] Error 2 make: Leaving directory `D:/Mehran/AndroidStudioProjects/TelegramTest/TMessagesProj/jni'

Sorry for my bad English.
