From: "Yann E. MORIN" <yann.morin.1998 at free.fr>
Starting with 1.4.0, weston requires wayland-scanner to build its DT
So far, we got away with just hand-building wayland-scanner, and made
that available in HOST_DIR/usr/bin
But now, weston also requires wayland's DTD, which we did not care of
in our dirty little hack.
So, the best solution is to just build a host-variant of wayland, so
we get both wayland-scanner, and the DTD.
But then, we do not build the target wayland-scanner (he, wayland tries
to run it at build time...). So it is a matter of just tweaking a little
bit the host .pc file (which weston uses to find wayland-scanner, sigh...)
and fake it as a target .pc file.
