xfwm4 build troubles

[Edscott Wilson García]

Hi Olivier,

  While building xfwm4, xfwm4/defaults and xfwm4/themes fail to build. For 
xfwm4/defaults I get a "no rule to make target defaults". 
While for xfwm4/themes I get:
required directory xfwm4/themes/linea does not exist
required directory xfwm4/themes/mofit does not exist
required directory xfwm4/themes/redmondxp does not exist
required directory xfwm4/themes/trench does not exist

xfwm4 compiles, but when I try to exec, it complains that it cannot find 
defaults and exits.

saludos,

Edscott
