As a convenience, cmake-gui uses a QSettings object to store the last
few build directories that it configured. These directories are
populated in the build directory dropdown menu.
The source directories are not stored in QSettings at all, but instead
extracted from the build directories. If the build directory hasn't
been configured, then CMake has no way of knowing what source directory
to pick.
