i have problem compiling layoutmanager.cpp due some include priorities, see this log:

It is better to not include anything before Qt headers. or write some special Qt include wrapper which will undef all possible defines which are breaking Qt includes before including actual Qt includes.

the includes outputgraphicsitem.h layoutmanager.h makes anothers inclusions that puts C headers before QT headers.. that's the problem
