For building on Windows with project files:
Assume $(WXWIDGETSROOT) is the root directory of your wxWidgets installation.
1. Open the file $(WXWIDGETSROOT)\include\wx\msw\setup.h
2. Search for the #define for wxUSE_GLCANVAS.
3. Change its value from 0 to 1.
4. Recompile the library.

Just use ./configure —with-opengl
