Build fails with Dplatform=android

I followed as Getting started - Meson build(https://github.com/nnstreamer/nntrainer/blob/main/docs/getting-started.md#build-with-meson) says.

However, when I tired to build with -Dplatform=android option, it first told me that CMake was not installed (I installed only the packages that document suggested in my docker image). I installed CMake and tried again, but this time it failed with the following meson-log.txt:
