[IPOL discuss] compiling for windows

[Juan Cardelino]

In our experience cmake+libpng is the cleanest way for IPOL in
windows. Cross compiling could help, but the ultimate test is to use a
native windows environment.
I have extensive experience using wine and, while it works, it
presents different behaviour in a considerable number of cases.

I know Nicolas will say: we don't have resources. But if we seriously
plan to support the 3 major platforms, we can't be testing this by
hand, we already have a considerable amount of demos to take care of.
I don't know how hard it is, but it will be interesting to count with
an automatic build system, which compiles in many diffferent machines.
Something in the spirit of ITK's dashboard:

In our lab, we plan to get another project after the initial IPOL-LA
initiative. I see this as an interesting part for a new IPOL related
project.
Best regards,
                   Juan
