I Agree, note that afaik there is no way to link against libX11.la without 
linking to the whole libX*.la ... unless you use X11_X11_LIB.
For instance, see what I did in kmplayer:
http://websvn.kde.org/?view=revision&revision=1046843
I could use X11_LIBRARIES, but, afaik I would be linking uselessly to the 
whole libX*.la.

The ones related with X11_X11_LIB; I *guess* that X11_Xlib_INCLUDE_PATH and 
X11_X11_INCLUDE_PATH should be documented too.
