Some foo-config scripts like freetype-config have an option
to display the library's .la file. However, it is more and more
common that .la files get removed by distributions if installed in
/usr/lib, as you are certainly aware.
My question is how to handle this properly. Shall the logic to test
for the existence of the .la in the foo-config file or in the
configuration script which actually uses foo-config? And what exactly
should be done if no .la file is available? I suppose it's best to
fall back to the standard foo-config option `--libs'.
Some info about this situation should be probably added to the libtool
