glfwCreateCursor was added in GLFW 3.1, you will have to update to 3.1 or newer.

Thanks. When I build and install GLFW, I forgot the last sudo ldconfig, so cyglfw3 can not find the new .so

$ cmake -D BUILD_SHARED_LIBS=ON ..
$ sudo make install
$ sudo ldconfig

Ah, thanks for posting those steps. It will help anyone else who runs into the same problem =)
