Examples fail to compile because of undeclared CLOCK_REALTIME
../examples/overlay_cairo_animation.c:38:7: warning: implicit declaration of function 'clock_gettime' [-Wimplicit-function-declaration]
38 | if (clock_gettime (CLOCK_REALTIME, &now) != 0)
| ^~~~~~~~~~~~~
../examples/overlay_cairo_animation.c:38:22: error: 'CLOCK_REALTIME' undeclared (first use in this function)
38 | if (clock_gettime (CLOCK_REALTIME, &now) != 0)
| ^~~~~~~~~~~~~~
I don't see an option to disable building examples either. Not sure if related, but this is being built on a Musl system.
