You need to install the shared libraries in a well known location such 
as /usr/lib or set the LD_LIBRARY_PATH environment variable to point to 
the location of the libraries. The approach I use is to start my 
application with a shell script that first sets any environment 
variables required by my application, then launches the application.
For example:
> #!/bin/bash
> # setenv __GL_SYNC_TO_VBLANK 1
> __GL_SYNC_TO_VBLANK=1
> #__GL_FSAA_MODE=1
> export __GL_SYNC_TO_VBLANK
