[CMake] cpack -G NSIS

[Andrea Crotti]

So yes this was with your try-out example, actually I can try to dig a 
little bit myself, the problem
is that with gdb I need to have the debug symbols, thus recompiling in 
debug mode.

But nowhere in the Readme or around the code I found a way to do it (it 
would be very nice
to add maybe somewhere)..

I found only this in the Makefile which might be useful, but I'm sure 
there is a smarter way
to just install with the debug symbols..

-DCMAKE_INSTALL_DO_STRIP=1

Thanks a lot,
Andrea
