compile pcl code pointcloud_to_pcd

edit

I have downloaded the code pointcloud_to_pcd and I am trying to compile it but I have errors.

I have created a new package ( pointcloud2occupancy) and inserted the source(pointcloud2pcd.cpp). I have modified the Cmakelists.txt file in lines:

• include_directories( ${catkin_LIBRARIES})
• add_executable(pc2og src/pointcloud2pcd.cpp)
• add_dependencies(pc2og pointcloud2occupancy_generate_messages_cpp)
• target_link_libraries(pc2og ${catkin_LIBRARIES} )

But catkin_make show this: fatal error: pcl/io/io.h: file or directory not found. #include <pcl io="" io.h="">

I think I should insert some dependence of pcl in package.xml or cmakelists.txt, and not only the lines #include in the source cpp. But I am not sure when I have to include "the includes" in those files and when not. Could some help me, please? Thanks in advance.
