Compilation issue on Windows with ninja

[diorcety]

On windows with ninja the precompiled.hpp can't be found. Put precompiled.cpp first doesn't solve the issue, a better dependency tree must be done.

I don't think we support ninja?

But it's windows stuff so I'm not really sure

[diorcety]

Ninja is not only for windows. But in this case, the issue appear because ninja doesn't process source in the given order. My fix force a dependency which force at the end the order

As I mentioned there's no support for it and afaik you're the first to ask, so if you are interested please do send PRs to add support for it

[bjovke]

@diorcety Thanks. I don't think building with ninja is supported for libzmq.

[diorcety]

Okay this is the only fix to do for supporting ninja :)
