我正在构建一个以https://github.com/j0r1/JRTPLIB为子目录的项目，因为我需要在构建项目之前先在其中构建一些内容。我添加了一个基于
的依赖项add_subdirectory(../third_party/JRTPLIB jrtplib)
add_library(myRtspClient SHARED ${SOURCES})
add_dependencies(myRtspClient jrtplib-shared)
其中jrtplib-shared是../third_party/JRTPLIB CMakeLists文件中的目标。
正如您所看到的here，生成了一些头文件并放置在一个非常规的地方。我项目中的这个地方是
android/app/.externalNativeBuild/cmake/debug/armeabi-v7a/jrtplib
其中jrtplib名称来自add_subdirectory(../third_party/JRTPLIB jrtplib)行
请注意，它还会将文件生成为 android/app/.externalNativeBuild/cmake/debug/x68/jrtplib
我需要将android/app/.externalNativeBuild/cmake/debug/armeabi-v7a/jrtplib或android/app/.externalNativeBuild/cmake/debug/x86/jrtplib中生成的头文件包含到我的项目中以完成编译。
我显然尝试include_directories(jrtplib)，但它没有用，找不到文件。
那么我应该如何包含从子目录生成的头文件？
