You should use the installed version of the library whenever possible 
(unless you really know what you're doing).  Pointing directly to the 
source tree usually leads to trouble at runtime.

Note that when pointing to the installed version, in general you 
shouldn't include the "lib" directory in the path, i.e. you should use

   --with-foo=/usr/local

Also note that some configure options want to be pointed to a 
configuration script and not to a directory, so you always need to read 
the "./configure --help" output or the docs to check what you need to 
pass. For instance, GDAL needs a reference to the gdal-config script, e.g.

   --with-gdal=/usr/local/bin/gdal-config
