[Ves] ndk-build NDK_DEBUG=1

[Pat Marion]

CMake is a replacement for Android.mk files and ndk-build.  CMake is
used to compile the VTK and VES libraries in a cross platform way, so
that they can be built for iOS, Android, and host architectures.

The file you are talking about is
Apps/Android/Kiwi/jni/KiwiNative.cpp.  This file is not part of the
VES cross platform library, it is part of the KiwiViewer app for
Android.  A CMakeLists.txt is provided to compile KiwiNative.cpp as a
shared library so that it may be loaded as a JNI library by the Kiwi
Java app.  Instead of using CMake to compile KiwiNative.cpp, you could
write an Android.mk file and use ndk-build, that will work fine.  The
reason that CMake is preferred is because it makes it easier to lookup
the required VES and VTK include dirs and libraries to link the JNI
shared library.  But, you could also list these things in an
Android.mk file and then use ndk-build.
