Hello,

The Find*.cmake code in CMake does not do a LINK_DIRECTORIES command
so that isn't it. But UseVTK.cmake and UseITK.cmake do make use of
LINK_DIRECTORIES. My guess is that your CMakeList file INCLUDEs some
other files such as UseITK.cmake and have built either VTK or ITK with
the [I or V]TK_LIBRARY_PATH set to nothing. I have checked in a fix
for CMake that handles LINK_DIRECTORIES with no arguments but it will
not show up for a day or two. If you can, take a look and see if that
is the issue.

Thanks
Ken
