* Launch Qt Creator and open the `qgroundcontrol.pro` project.
When you open a project in Qt Creator for the first time, it will ask what targets (*Kits*) you want to target. The options will depend on what modules you downloaded above. For instance, on Mac OS X you would select *Desktop Qt 5.4.1 clang 64bit*.
It's also a good idea to go into *Projects/Build Steps* (side tool bar) and select Make's *Details*. For *Make Arguments*, add `-jx` (`/J x` on Windows) where `x` is at least the numbers of cores you have. That is, if you are running on a Mac Pro with 24 cores, you would use `-j24`. That will run 24 concurrent compiler instances at a time and run the build a whole lot faster. Your mileage may vary depending on your disk IO throughput.

That will run 24 concurrent compiler instances at a time and run the build a whole lot faster. Your mileage may vary depending on your disk IO throughput. Note that for Windows, this method will build QGC x many times faster than when using Visual Studio as described above. Visual Studio allocates one process per *Project*. As QGroundControl is one very large project, it will still compile one file at a time within that one process. When you build from within Qt Creator (and give the ```/J x``` option to make), it will use x number of concurrent compiler processes.
Qt Creator is a full-blown development IDE. You can even debug right from within it and it provides the full Qt API documentation. Just place the mouse cursor over a Qt class/element and hit the F1 key.
