[CMake] Finding Parent Directory for a Library

[Mike Jackson]

I need to get the Parent Directory for a library so I can add that  
directory to the LINK_DIRECTORIES().

I have this so far:


FIND_LIBRARY(MXADataModel_LIBRARY "MXADataModel"
   /usr/local/lib
   /usr/lib
   "${MXA_DIR}/lib"
   CACHE
)

Which will put the path to libMXADataModel.dylib" into the variable,  
How do I get its parent?
