Qt - dependent class

Question

I've added a class to my project. After some time I resigned from that class and removed both source and header (from Qt Designer). Class is not included or imported anywhere, but when I build project, i'm getting message:

:-1: error: dependent 'C:\Qt\Project\dists\registration.h' does not exist.

I tried to search for registration.h over all files in project, deleted debug folder. There are no any result. Class is not referenced anywhere. Still can't build project.

Where are these hell dependencies then?

Answer 1

Ok, I've figured it out. Strange...

I've removed files dists.pro.user and dists.pro.user.ddfc87e. After new project configuration it started to work (if someone knows why, will be great to know it... )

Thanks for attention ;)
