Reading through the toolchain file <https://android.googlesource.com/platform/ndk/+/master/build/cmake/android.toolchain.cmake>, ANDROID_PLATFORM will be calculated from ANDROID_NATIVE_API_LEVEL. So that should not be the issue.
I'd start by pepper-spraying message() calls in toolchain .cmake file, and in other .cmake files as necessary, too.
