Cannot get Boost library to work

Sirs/Madams

I installed Boost library by using GetIt Package manager under Tools menu. Everything went ok and package is now installed and I can see it for example in Project Options and Environment Block, I mean in the System Variables.

But when I try to compile something simple, basically I just make new project and only thing what I add into Unit.cpp file is:

#include

And then I try to compile. Error what I get is: E2209 Unable to open include file 'boost/fusion/include/unused.hpp'. Basically compiler cannot find include files. Files are ok on my hard drive in the directory where they are suppose to be and environment variable is also ok.

Any idea why compiler cannot find "*.hpp" s

thanks in advance
