That means there is a bug in the kde4 build system.  It is using -lsolid 
to link a library but did not specify a link_directories call to add the 
appropriate library directory.  It worked before as a side-effect of 
CMake's previous linking implementation which added -L for everything 
(and another library that was specified with a full path appears in the 
directory containing the solid library).

The linking implementation is going through an overhaul so there have 
been more changes since your original post.  Please update to the latest 
CVS CMake and try again.

There is a compatibility feature to work around projects with this bug. 
  It is enabled if you set CMAKE_BACKWARDS_COMPATIBILITY to 2.4 or 
lower.  You can also explicitly enable the work-around by running this 
in your build tree:

   cmake -DCMAKE_LINK_OLD_PATHS:BOOL=ON .

Please let me know if this works.  The current linking implementation is 
very new and I want to make sure all these compatibility issues are 
worked out.

Thanks,
