It's documented in the cmake-toolchains(7) manual:

The basic usage is:

```
$ cmake ../src \
  -DCMAKE_SYSTEM_NAME=Android \
  -DCMAKE_SYSTEM_VERSION=21 \
  -DCMAKE_ANDROID_NDK=/path/to/android-ndk
```

The ANDROID_NDK environment variable is among the documented ways to
specify the path to the NDK instead of defining CMAKE_ANDROID_NDK.
