- Download and install the required dependencies. (Qt5, CPython, mpdecimal and libarchive)
- Open the CMakeLists.txt file in your favorite IDE.
- Build the "qcalc" cmake target.
- (win32 only) Because the windows PySide2 implementation requires special Qt dlls you have to copy the Qt dlls from PySide2 to the build directory. (Qt5Core.dll, Qt5Gui.dll, Qt5Widgets.dll, styles/qwindowsvistastyle.dll and platforms/*.dll)
