[Evolution] Problem compiling evolution ews

["pablo a saavedra gmail com" <pablo a saavedra gmail com>]

Hi,

I updated to the latest evolution ews from git (git://git.gnome.org/evolution-ews) and it fails to compile with the following error:

make[2]: Entering directory `/home/pablosaavedra/projects/opensource/evolution-ews/src/calendar'
  CC     libecalbackendews_la-e-cal-backend-ews.lo
In file included from /usr/include/evolution-data-server-2.32/camel/camel.h:124:0,
                 from e-cal-backend-ews.c:44:
/usr/include/evolution-data-server-2.32/camel/camel-tcp-stream.h:47:18: fatal error: prio.h: No such file or directory
compilation terminated.


Any idea what can be the cause of this?
Thanks in advance.
