Not providing "Findncnn.cmake" in CMAKE_MODULE_PATH

[yuqing-liu-dut]

您好，在搭建Demo过程中，我下载并使用了官网的预编译库，在Android Studio中运行后报以下错误：

By not providing "Findncnn.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "ncnn", but
CMake did not find one.

请问是什么原因？要如何解决？

CMakeLists.txt
set中需要提供ncnn-{version}-android-vulkan正确的路径

路径正确了，cmake只构建了v7a和x86；构建v8a就直接报这个错误了（（

问题解决了，需要令NDK编译适应各种CPU架构，在src/build.gradle文件里面加入
defaultConfig {
applicationId "com.tencent.MobileUnet"
archivesBaseName = "$applicationId"
//cpu兼容
ndk {
moduleName "ncnn"
abiFilters "arm64-v8a","x86"
}

    minSdkVersion 24
}
