Qt Creator extremely slow when adding large library INCLUDEPATH

Hallo,

i need to use /usr/include/eigen3/ for a project.
As soon as i add "INCLUDEPATH += /usr/include/eigen3/ " to the project Qt Creator gets really slow.
(some seconds for copying word to the editor)
Any ideas haw to fix this. I found some post that suggested adding the path to QMAKE_CXXFLAGS would help, but it didn't.
I guess it has something to do with auto-complete / syntax-highlighting of classes?

Can you try with a more recent version ? Current is 4.2

Hi and welcome to devnet,

Quoting myself:

Which may or may not apply to your case.
