In Mesa 6.1 we modified the conventional Makefile system.
Instead of specifying all the various system configurations in the
Make-config file, there's a directory named <code>configs/</code> which
has an individual file for each configuration.
One of the configs gets copied to <code>configs/current</code>, which
is then included by all Makefiles.

If you install the libraries in a non-standard location you can use
LD_LIBRARY_PATH (on Linux) to switch between the Mesa libs and another
vendor libs whenever you want.
Note: at runtime, you can set the LD_LIBRARY_PATH (on Linux) to switch
between the Mesa libs and another vendor libs whenever you want.
This is a handy way to compare multiple OpenGL implementations.
