No offense, but from the questions you ask, you don't know enough about programming to build this project. The Virtual MIDI Keyboard project requires another package, called "DrumstickRT", that you will also probably have to build from source code. It also may require dbus. After that, it may require CMake to configure the Virtual Keyboard project before it can be built and linked in with Qt and the drumstick library. The .pro file contains paths to libraries and include files that probably don't match what you have on your PC. It is impossible to give you "step by step" instructions for a project as complex as this.

If you are trying to learn Qt and C++, why don't you start with the examples and tutorials that come with Qt instead of downloading random projects that look interesting to you? You are only getting yourself lost and confused. The Qt examples can be built and run using nothing more than what comes with the Qt distribution.
