[Vm-dev] xcode and VM plugins

i agree that using CMake for building VM is good because it is
cross-platform tool.
So, it is obvious choice for automating building tasks.
But not when you in developing/debugging mode, since you need UI to
see what happens, (don't tell me gdb is all UI i need ;)
That's where integrated dev environments like xcode rocks.

So, i wonder if its possible to have a cake and eat it too :)
