我已经从Github (link)下载了WireGuard，在安卓工作室运行app后，我遇到了这样的错误：
ERROR: Cause: executing external native build for cmake /path/to/project/app/tools/CMakeLists.txtandroid_gradle_generate_cmake_ninja_json_x86.stderr.txt展示了这一点：
CMake Error at CMakeLists.txt:11 (add_executable):

我使用的是ubuntu 18.04中的Android studio 3.5.3和gradle 5.4.1。NDK(并排)，LLDB和CMake也安装了。然而，我在事件日志中看到这个警告(而不是错误)：NDK Resolution Outcome: Project settings: Gradle model version=5.4.1, NDK version is UNKNOWN in all project。即使是那些不使用ndk的用户。在local.properties中我定义了：
ndk.dir=/home/hadi/Dev/Android/android-sdk/ndk/21.0.6113669
sdk.dir=/home/hadi/Dev/Android/android-sdk有谁可以帮我？

这个存储库有一些子模块，必须使用额外的选项进行克隆。正如在github页面的自述文件中提到的，我必须通过以下命令克隆项目：
$ git clone --recurse-submodules https://git.zx2c4.com/wireguard-android
$ cd wireguard-android
