You have any evidence for that? Usually cross-platform doesn't mean
"ignore the platform conventions", but simply abstract away from that.
In that sense I'd expect cross-platform apps to have something like

add_executable(foo WIN32 MACOSX_BUNDLE ${SRCS})

since cmake will simply ignore the windows/macosx specific flags on
platforms that they don't apply on.

For a CMake release I'd say that the generator should fully work on all
platforms it is enabled on. If there are things that are not supported
on a platform, disable it there.
