Indeed it is, Pau. Remember that we changed all plugins so that they can be 
used as library as well. Plugins must be compiled apart, To link against them 
just use pkg-config with clam-spatialization module and you will get the flags 
to compile. You can include headers, for example, as 
<CLAM/spatialization/CrossCorrelation.hxx>
