使用NDK 20为Android编译Opus

我正在编译opus，以便在Android上使用它。我尽力用正确的标志和源组成正确的CMakeLists文件。现在的情况是这样的：

cmake_minimum_required(VERSION 3.4.1)

add_compile_options(-DOPUS_BUILD -DUSE_ALLOCA -DFIXED_POINT -D__OPTIMIZE__)

include_directories(opus/include
                    opus/src

                    opus/silk/fixed
                    opus/silk/arm
                    opus/celt
                    opus/celt/arm)

add_library( # Sets the name of the library.
             jnopus

    # Sets the library as a shared library.
    SHARED

    # Provides a relative path to your source file(s).

到目前为止，它的工作，但我不确定是否有一些错误或遗漏的东西。。。感觉有点奇怪

我还设法只编译“定点”版本，因为“浮点”版本不起作用。如果有人知道如何做到这一点（除了添加浮动源）

你是如何完成这个项目的？没有进一步跟进，这是一个次要功能，我必须转到下一个项目。你是如何完成这个项目的？没有进一步跟进，这是一个次要功能，我必须转到下一个项目。
