cygwin comes with two flavours of opengl libraries. The native and the X11 ones.
The native ones have headers in /usr/include/GL and libraries in /usr/lib, the 
X11 ones have the headers in /usr/X11R6/include/GL and libraries in /usr/X11R6/lib

By adding -I/usr/include you force using the native headers but you link with the 
X11 libraries. Change the -I/usr/include to -I/usr/X11R6/include.
