instead of -DHAVE_ECORE_X_XCB in the pc, which is a super-hack, add a
proper compile-time generated ecore_x_version.h that is included by
Ecore_X.h
This file contains HAVE_ECORE_X_XLIB or HAVE_ECORE_X_XCB defined and
will also define ECORE_X_VERSION_MAJOR and ECORE_X_VERSION_MINOR as
per other EFL (Ecore), also defining the runtime version in
Ecore_X_Version.
