Cannot switch NDK for existing project

When creating or importing a project, the CMake variables CMAKE_TOOLCHAIN_FILE and ANDROID_NDK are hardcoded to the paths to the ndk in the project's "Initial Configuration".

This results in a fixed NDK for that project. Changing the default NDK in the Android settings doesn't take effect (only for the compilers and debugger)

The initial configuration should use some variable like %{Android:NDK} or so
