Ryan, when building via CMAKE, and doing static builds, shouldn't it
define the preprocessors for you depending on what you want (zip, 7z,
whatever)?
In our case, was making a static lib, but we didn't want zlib
compiled, since that is used in 3 or 4 other libs, but we do want zip
support enabled.
Is that a bug with cmake, or is that just by design, or is that a user
error didn't see the right option type of thing ?
Was building a VS2k10 project, dunno if it matters or not.
