LibreOffice SDK include files missing

Hello. I installed libreoffice and libreoffice-dev and try to compile the C++ extension examples. The C++ code contains lines as
#include <com/sun/star/beans/XPropertySet.hpp>
#include <com/sun/star/bridge/XUnoUrlResolver.hpp>
#include <com/sun/star/frame/Desktop.hpp>

but the sdk/include/com/sun/star directory contains only one uno subdirectory, neither beans, nor bridge nor any others. My OS is Linux Mint 22 “Wilma”.
Which package(s) should I install in order to get them? Thank you in advance.

No. All the packages libreoffice-dev* are installed, but it doesn’t help.

hpps should come from IDLs → https://opengrok.libreoffice.org/search?project=core&full=&defs=&refs=&path=com%2Fsun%2Fstar%2Fbeans%2F&hist=&type=&xrd=&nn=1

how have you tried to build ?

I’ve just found a solution. These headers don’t present straight out of the box, but are generated. Now I succeeded to build.
