How might one run an NDK Cmake build independently from the rest of an Android project, ideally from the command line, external to Android Studio?
The equivalent of running ndk-build from the jni directory for slightly older Android NDK projects.
I need to investigate exactly what the calls to the compiler look like, and I can't seem to get this information when building the whole project from within Android Studio
My first attempt was just to run cmake from the project/app directory containing CMakeLists.txt, but this informs me that cmake is not installed - so how is Android Studio managing to build it then?

Running CMake from the command line To run in interactive mode, just pass the option “-i” to cmake. This will cause cmake to ask you to enter a value for each value in the cache file for the project. The process stops when there are no longer any more questions to ask.
The Android Native Development Kit (NDK): a set of tools that allows you to use C and C++ code with Android. CMake: an external build tool that works alongside Gradle to build your native library. You do not need this component if you only plan to use ndk-build.
If your goal is to just run from the command line (as opposed to trying to do exactly what gradle is doing), just use cmake the way you normally would:
$ cmake -DCMAKE_TOOLCHAIN_FILE=$NDK/build/cmake/android.toolchain.cmake \
-DANDROID_ABI=whatever $YOUR_SOURCE_DIR
Alternatively, you can just run ./gradlew from the command line.
