[ale] How do I force a specific version of a shared library to be loaded/used?

[Jim]

I have two versions of mysqlclient installed on the system, 
mysqlclient.so.14 and mysqlclient.so.12.  I'm compiling/running a 
program that needs to be linked to 14, but it's defaulting to 12.  How 
do I encourage it to link to 14?  Google wasn't much help.

Thanks,
Jim.
