Error compiling Android NDK

Hello guys, I'm trying to compile the last version of the example LoadBalancing for Android NDK. I tried with Visual Studio 2010 and 2015 with VisualGDB installed, and also via cygwin + ndk-build, I don't know how to fix these errors:

NDK in cygwin :
$ /cygdrive/e/UDK/nvpack/android-ndk-r10b/ndk-build
Android NDK: ERROR:jni/Android.mk:photon-cpp-static-prebuilt: LOCAL_SRC_FILES points to a missing file Android NDK: Check that jni/../../Photon-cpp/obj/local/armeabi-v7a/libphoton-cpp-static.a exists or that its path is correct/cygdrive/e/UDK/nvpack/android-ndk-r10b/build/core/prebuilt-library.mk:45: *** Android NDK: Aborting . Alto.


VisualStudio2010: Configured with the java and android sdks, and the ndk paths, everything set, even the project properties, in release configuration...

is there anywhere a guide to compile this project properly?
I was able to compile the Windows version of LoadBalancing with Visual Studio 2015, but this is giving me headaches, so,
Thanks!.
