Maybe have a look at Android Studio and their toolchain. For 
C/C++ they use CMake and the output is in a folder called 
".externalNativeBuild/cmake/". It produces the following output 
(in my project):

- arm64-v8a
- armeabi-v7a
- x86
- x86_64

Maybe it'd make sense to look at the respective toolchains first, 
Android Studio and Xcode.

Also, have a look at Kotlin Multiplatform[1], especially the 
Android-iOS integration[2]. It compiles the code that apps have 
in common to native and it uses the LLVM toolchain. Afik, they 
modified it a bit, check it out on Github[3].
