Since paths specified on the command line like Ben's first attempt 
should probably take the highest priority I have now generalized the 
path ordering a bit.  Paths are now searched like this for libraries:

1.) Paths listed in the CMAKE_LIBRARY_PATH variable in the cache.
2.) Paths listed in the CMAKE_LIBRARY_PATH environment variable.
3.) Paths listed in the LIB environment variable.
4.) Paths listed in the call to the FIND_LIBRARY command.
5.) Paths listed in the PATH environment variable (useful for DLLs on 
windows).

and for include files:

1.) Paths listed in the CMAKE_INCLUDE_PATH variable in the cache.
2.) Paths listed in the CMAKE_INCLUDE_PATH environment variable.
3.) Paths listed in the INCLUDE environment variable.
4.) Paths listed in the call to the FIND_PATH command.

This order IMO is most-specific to least-specific for a particular 
system, project, user, and build tree.
