Higer version of CMake required when generating aar for ffmpeg extension.

[tpuserhp]

In my other issue #10354 it was suggested that I should rebuild the extension every time I upgrade ExoPlayer. I am using Exoplayer 2.18.0. When I tried to rebuild the ffmpeg extension, I got error message that CMake '3.21.0' or higher was not found. I only have CMake version 3.10.2 installed. CMake 3.18.1 is the highest version I can find under the CMake section of SD Tools. I manually downloaded CMake 3.23.2 and made config changes according to https://developer.android.com/studio/projects/install-ndk. I did not install the Ninja build system as I thought it is for performance improvement only. But I got error like could not get version from cmake.dir. I gave up after a few tries.
Finally I changed the CMakeLists.txt to use 3.10.0 for cmake_minimum_required. I also changed ffmpeg build.gradle to 3.10.2 for android.externalNativeBuild.cmake.version. This allows me to generate the aar successfully.
For this error, what should be the best solution? To install a higher version of SDK that comes with the support of CMake 3.21.0 (or above) or manually download the supported CMake version like what I did? Where can I find the corresponding SDK and Cmake versions? Thanks.
I gave it another attempt after a good night sleep and was able to use the CMake 3.23.2 that I manually downloaded to build the ffmpeg extension aar. But I'd still want your input on methods to handle the requirement of a higher CMake version and
the website I can find the cross reference of Android SDK version and the CMake version. Thanks.

The latest Android Studio (Dolphin | 2021.3.1 Beta 4) includes CMake 3.22.1. I assume this can be marked as fixed?
