Yes.

It will use whatever qmake you give it, as before.

Normally bindings don't link against Python, they are dynamically loaded 
by the interpreter.

It doesn't build sip or a private sip module.

You need to install sip first (unless it is being installed 
automatically because you are using pip as the build frontend). Don't 
confuse sip and a sip module.

At the moment sip5/PyQt-builder don't have explicit support for 
cross-compilation. This will be fixed (if necessary) when sip5 support 
is added to pyqtdeploy.
