This is a potential build fix for a problem Martin reported that I
couldn't reproduce myself.

I've pushed this on top of the piglit branch that isn't yet merged.

Thanks,

+Subject: [PATCH] cmake: Link utils with xcb explicitly
+
+Linking with g++ can reportedly lead to:
+
+libpiglitutil_gl.so.0: error: undefined reference to 'xcb_connect'
+libpiglitutil_gl.so.0: error: undefined reference to 'xcb_get_setup'
+libpiglitutil_gl.so.0: error: undefined reference to 'xcb_setup_roots_iterator'
+
+This may have appeared now because xcb-dri2 used to overlink publicly
+but now does not.
