wxNURBS uses wxWidgets as the windowing toolkit. To download wxWidgets, goto http://www.wxwidgets.org.
Important: Please get version 2.4.2 of wxWidgets for building the application
Please install wxWidgets in a path that does not have spaces, say C:\Programs\wxWindows-2.4.2. For some reason, MinGW is not very happy with spaces in the path.
