antlr/AST.hpp: No such file or directory

Hi,
I am trying to compile an application. After the ./configure step, make is giving these kinds of problems:

error: antlr/AST.hpp: No such file or directory
antlr/config.hpp: No such file or directory
error: antlr/TreeParser.hpp: No such file or directory

and so on. So i downloaded antlr from the repos (packman, updates, oss and non-oss), but the problem persists since these files are not there anywhere, since i did a

find / -name AST.hpp

and so on search. Where can i find these files?
