[Cmake] Link Lib Bug?

[John Biddiscombe]

The Library commands in cmake appear to be a bit unselective. I'm dumping 
out the lib linked to by each target...

example

Mace_LINK_LIB =  \
   C:/PROGRA~1/Tcl/bin/tcl83.lib \
   opengl32 \
   C:/Program Files/Tcl/lib/tk82.lib \
   vtkCommon \
   vtkFiltering \
   vtkImaging \
   vtkGraphics \
   vtkRendering

vtkRendering_LINK_DIR =  \
   C:/PROGRA~1/Tcl/bin/tcl83.lib \
   opengl32 \
   C:/Program Files/Tcl/lib/tk82.lib \
   vtkCommon \
   vtkFiltering \
   vtkImaging \
   vtkGraphics

Mace and Rendering are linking to tcl and tk when these are selected. This 
is wrong. How do I stop this? (Only the Rendering_TCL should be doing this).

[Should the ADD_LIBRARY(stuff) command have the target(s) specified?]

[NB. I may be doing something wrong, in which case please correct me!]

thanks
