There not much to this beyond the official instructions. Just note that the last version on the NDK I could get this to work with
android-ndk-r17c. I believe it has something to do the the removal of GCC. Thankfully you can just download that specific version
as a standalone archive. I built the shared libraries with that NDK and was able to use them without issue with Apps built against
the lastest NDK.
No idea if there are hidden bugs are lurking.
android-ndk-r17c excute the following build command from the
jni sub folder in the TBB folder.
