[OE-core] Nothing provides libxcb-*

[Jack Mitchell]

I am trying to use the package libxcb-xfixes in a recipe however when I 
add 'libxcb-xfixes' to DEPENDS I get the error that nothing provides 
libxcb-xfixes however the libxcb package clearly has it in the PACKAGES 
variable

recipes-graphics/xcb/libxcb.inc:PACKAGES =+ "libxcb-composite 
libxcb-damage libxcb-dpms libxcb-glx \
recipes-graphics/xcb/libxcb.inc: libxcb-randr libxcb-record 
libxcb-render libxcb-res \
recipes-graphics/xcb/libxcb.inc: libxcb-screensaver libxcb-shape 
libxcb-shm libxcb-sync \
recipes-graphics/xcb/libxcb.inc: libxcb-xevie libxcb-xf86dri 
libxcb-xfixes libxcb-xlib \
recipes-graphics/xcb/libxcb.inc: libxcb-xprint libxcb-xtest libxcb-xv 
libxcb-xvmc \
recipes-graphics/xcb/libxcb.inc: libxcb-dri2"

I have also tried using others in this package list to no avail, can 
anybody comment on how I should be using these packages?
