Android NDK：make：***无法制定目标。停止

我正在尝试使用NDK构建libusb。这里是我的Android.mk和Application.mk我已经检查了这个线程Android NDK: No rule to make target，但它不适合我。Android NDK：make：***无法制定目标。停止

Android.mk

include $(CLEAR_VARS) 
LOCAL_MODULE := libusb 
LOCAL_SRC_FILES := libusb/core.c libusb/descriptor.c libusb/io.c libusb/sync.c libusb/os/linux_usbfs.c 

LOCAL_LDLIBS := -llog 
include $(BUILD_SHARED_LIBRARY)

Application.mk

APP_ABI:= all 
APP_LDFLAGS:= -llog 
APP_STL:= stlport_shared 
APP_CPP_FEATURES:= exceptions 
APP_PLATFORM:= android-21 
APP_CFLAGS:= -g

的build.gradle

apply plugin: 'com.android.application' 

apply plugin: 'kotlin-android' 

apply plugin: 'kotlin-android-extensions' 

android { 
    compileSdkVersion 26 
    buildToolsVersion "26.0.0" 
    defaultConfig { 
     applicationId "com.williams.libusbpoc" 
     minSdkVersion 21 
     targetSdkVersion 26 
     versionCode 1 
     versionName "1.0" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    implementation fileTree(dir: 'libs', include: ['*.jar']) 
    androidTestImplementation ('com.android.support.test.espresso:espresso-core:2.2.2', { 
     exclude group: 'com.android.support', module: 'support-annotations' 
    }) 
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" 
    implementation 'com.android.support:appcompat-v7:26.0.0-beta2' 
    testImplementation 'junit:junit:4.12' 
    implementation 'com.android.support.constraint:constraint-layout:1.0.2' 
}

local.properties

ndk.dir=C\:\\android-ndk-r15

项目结构看起来象下面这样：

当我运行ndk-build然后我得到

ndk-build 
Android NDK: WARNING: APP_PLATFORM android-21 is higher than android:minSdkVersion 1 in D:/williams/android/libusbpoc/app/src/main/AndroidManifest.xml. NDK binaries will *not* be comptible with devices older than android-21. See https://android.googlesource.com/platform/ndk/+/master/docs/user/common_problems.md for more information. 
make: *** No rule to make target `C:/android-ndk-r15/build//../sources/cxx-stl/stlport/libusb/core.c', needed by `D:/williams/android/libusbpoc/app/src/main/obj/local/arm64-v8a/objs/usb/libusb/core.o'. Stop.

有谁知道我做错了吗？

您似乎忘记设置LOCAL_PATH，即在你Android.mk你应该有：

LOCAL_PATH := $(call my-dir) 
include $(CLEAR_VARS) 
# ..etc as before..
