Include dependencies as SYSTEM libraries (!779) · Merge requests · tango-controls / cppTango

Michal Liszcz requested to merge github/fork/mliszcz/include-dependencies-as-system into tango-9-lts Oct 18, 2020

I just noticed that I'm getting tons or warnings like:

/home/michal/Documents/tango/prefix/omniORB-4.2.3/include/omniORB4/messaging.hh:252:18: warning: 'Messaging::Poller::_PR_copy_state' hides overloaded virtual function [-Woverloaded-virtual]
    virtual void _PR_copy_state(Poller*);

on clang 10.0.1 and omniORB 4.2.3.

This PR changes the way how we include directories for dependent libraries. They are now always included as 'system' libraries and any compiler warnings they emit are suppressed.
