I’m getting error while executing the android-project created on Cocos2d-x, The error is:

ERROR: You are using a non-Cygwin compatible Make program.
Currently using: D:/Cocos2d-X/Cygwin/bin/make

To solve the issue, follow these steps:

1. Ensure that the Cygwin 'make' package is installed.
   NOTE: You will need GNU Make 3.81 or later!

2. Define the GNUMAKE environment variable to point to it, as in:

     export GNUMAKE=/usr/bin/make

3. Call 'ndk-build' again.

I have installed all the required SW and set the path, environment etc properly,

NDK_PROJECT_PATH D:\Cocos2d-X\cocos2d-x-2.2.5\projects
