我从一个类似的问题中找到了答案，它添加到了

CMakeLists.txt

if(${ANDROID_ABI} STREQUAL "armeabi-v7a")
    include_directories(${ANDROID_SYSROOT}/usr/include/arm-linux-androideabi)
elseif(${ANDROID_ABI} STREQUAL "arm64-v8a")
    include_directories(${ANDROID_SYSROOT}/usr/include/aarch64-linux-android)
else()
    include_directories(${ANDROID_SYSROOT}/usr/include/arm-linux-androideabi)
endif()

但出现了另一个错误：

错误消息是

找不到-lcamera2ndk

。您是否安装了camera2ndk软件包？非常感谢。MinSDK版本不支持camera2ndk。我尝试使用更高的版本。
