[IGSTK-Developers] New build system

[Julien Jomier]

Hi Andinet,

The problem is that I tend to modify the copied files and not the 
original ones.

I think I found another way to deal with that.

We create an IGSTK directory in the sandbox (Sandbox/IGSTK) that copies 
the file structure of the main IGSTK repository. The idea is to copy all 
the source from IGSTK to Sanbox-bin (using CMake) except the files that 
are in Sandbox/IGSTK (and subdirectories). We then compile the IGSTK 
library inside the sandbox. But there is no duplicate of the files at 
that point. Do you foresee any issues in doing that?

Let me know what you think about this design,

Julien
