Following that thread:
I'm trying to set per-project includes to be used by semantic (in this very case: /usr/include/gtk-3.0/). So far, semantic's completion is aware of my include only when using semantic-add-system-include; nonetheless, my problem is that I cannot seem to get this setting to be persistent other than perhaps using the cpp-root-project (which I'd prefer to avoid since my project is an Automake). I would also like to ensure that my project tags cache really is used and that parsing every tag won't be necessary each time I'm opening the project (this might actually be the case but if it's not, I'd really appreciate some suggestions in that direction).
Some precisions about this would greatly be appreciated...
