[LAD] Autotools and missing headers.

Hello, I try to develop some Autotools scripts for my project and I'm getting following make/compile errors: In file included from and.cpp:1: /usr/include/lv2plugin.hpp:34:25: error: lv2_uri_map.h: No such file or directory /usr/include/lv2plugin.hpp:35:29: error: lv2_saverestore.h: No such file or directory /usr/include/lv2plugin.hpp:36:23: error: lv2_event.h: No such file or directory /usr/include/lv2plugin.hpp:37:26: error: lv2_contexts.h: No such file or directory /usr/include/lv2plugin.hpp:38:24: error: lv2types.hpp: No such file or directory configure.ac: # -*- Autoconf -*- # Process this file with autoconf to produce a configure script.
