I am trying to download and install VXL for use with opengl. I referred to http://vxl.sourceforge.net/releases/install-release.html document for procedure to install VXL.

I downloaded CMake and followed all the instructions accordingly.

But in the end when I build the ALL_BUILD target I am getting
Build: 26 succeeded, 538 failed

And the CTest.exe does not run at all a message comes:
No Test Configuration File Found!

What am I doing wrong?

Any advice which can get me VXL running is appreciated.

So what do you suggest is the better alternative.

My application is to capture the screen using opengl.

Like not just opengl application, desktop and any and every application running.

I started off with the screenshot documentation on programmingexample[dot]net.

There it was mentioned the code requires VXL libraries.

Which other library should I use then for screencapture?

Corona? OpenCV? Devil?
