How to build
CMake is used to generate native build projects for target platform.
Windows, Visual Studio 2015
mkdir Build
cd Build
cmake -G "Visual Studio 14 2015 Win64" ..
cmake --build . --config Release
Visual Studio 2013 may also work.
MacOS, Xcode
mkdir Build
cd Build
cmake -G Xcode ..
cmake --build . --config Release
Linux
Linux support is not fully implemented.
How to run
Run ProbulatorGUI from the build output directory (Build/Source/ProbulatorGUI/Release by default).
