I did not think that I could use a full path to a library in the TARGET_LINK_LIBRARIES. Is that right? I don't think what you suggest will work:
 
     TARGET_LINK_LIBRARIES ( <target> <child libs> ${Boost_LIBRARIES}
            ${MYSQLCPPCONNECTOR_LIB_DIR}/debug/mysqlcppconn-static.lib )
 
So I was looking at add_library. I am not sure I get the IMPORTED_LOCATION_<config>. First off what can I use for <config>? I tried IMPORTED_LOCATION_DEBUG but that gave me an error from cmake-gui saying its was an unknown cmake command. The documentation does not clearly define what <config> is other than stating its a configuration. Can you provide a simple example of what you are suggesting?
