Android Studio project building successfully, but cmake not generating native library

I've been building my Android Studio project with a native library along side it, and up to this point it has worked just fine. Recently, it started not outputting the native library. Everything still builds successfully, however I don't see any output in the build log related to the native library and I'm unable to run the application on a device as it fails when trying to use the library now with a java.lang.UnsatisfiedLinkError error.

I think this issue might be related to the fact that i switched over to building it as a STATIC library instead of a SHARED library.

My Application level build.gradle:
